[HUAG]Italia-JSF F-35 Thread Ufficiale

[dvd100]

credo che non si tratti di rimpiazzo ma di affiancamento dei due aerei

[maxsona]

Primo non esiste una versione imbarcata dell F-22, secondo il JSF avrà un ruolo completamente diverso, cioè quello di bombardiere leggero mentre il compito del Raptor è la difesa aerea, possiamo dire che il JSF stà all'F16 come il Raptor stà all'F15.

Ragazzi, mi stavo chiedendo, mentre il 35B è in hovering, quindi a velocità 0 come fa il pilota a governare l'aereo? Mi spiego, a velocità 0 i tradizionali timoni di profondità ovviamente non hanno nessuna utilità. Sull'harrier era stato risolto con dei getti di aria compressa per poter indirizzare l'aereo, con il Lightning II è la stessa cosa?

La domanda è vecchia ma mi era sfuggita.Rispondo ora per completezza.

Questo è lo schema del motore della versione a decollo verticale





L'ugello principale collegato al motore controlla l'imbardata
Gli ugelli posti nelle ali controllano il rollio



@Ventresca:l'F-35 verrà affiancato all'F-22,il quale è più grande,più veloce,più stealth,con più autonomia,carico bellico ecc ecc.
E' praticamente il fratello maggiore



@Kurak:ciao e benvenuto!Anche TXFW ci lavora ma purtroppo si fa sentire sempre più di rado

Il programma prosegue su tutti i fronti

PARIS: With 11 test aircraft on the assembly line, nine nations signed onto the program's production and sustainment phase, one aircraft deep into flight testing and another nearing completion, the F-35 Lightning II program is meeting its schedule and budget targets, and is on track to begin deliveries to the armed services in 2010.

"The Lightning II is a sophisticated machine and the program is extraordinarily complex, but the absolute commitment demonstrated by our international team is driving success after success, from the aircraft's first flight last December to the phenomenal accuracy and quality shown in the manufacturing process," said Tom Burbage, Lockheed Martin executive vice president and general manager of F-35 program integration. "We're proud that these and other remarkable achievements are the result of a global effort from our friends all over the world."

The first F-35, a conventional takeoff and landing (CTOL) variant, has completed 19 test flights to date and has shown unusually high reliability for a first-article aircraft. The second F-35, a short takeoff/vertical landing (STOVL) version, is on schedule for completion later this year and flight testing in 2008.

Assembly quality of the first two aircraft already is surpassing that of fighters whose production processes are mature. Critical Design Review (CDR) for the carrier variant, designed for the catapult launches and arrested landings of a large aircraft carrier, is under way. CDRs for the CTOL and STOVL variants were completed successfully in 2006 and underscored the F-35's design maturity. Software development, historically a challenge on highly complex aircraft like the Lightning II, remains on track six years into the F-35's System Development and Demonstration phase.

In late 2006 and early 2007, all of the F-35 partner nations signed an agreement to extend their participation into the program's Production, Sustainment and Follow-On Development phase. Those countries are the United States, the United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway. Each country is involved in the design and production of the F-35.

Funding for the first two production-model Lightning IIs is approved, parts fabrication for these aircraft is under way and component assembly will begin later in 2007. The pair of F-35A aircraft are the first of 1,763 scheduled for delivery to the U.S. Air Force, beginning in 2010. The U.S. Marine Corps and Navy together are planning to operate 680 F-35Bs and F-35Cs, and the United Kingdom plans to place 138 F-35Bs into service with the Royal Air Force and Royal Navy. The remaining F-35 participant countries plan to acquire from 600 to 700 aircraft, and further international sales are expected to create a demand for hundreds more Lightning IIs.

The F-35 is a supersonic, multi-role, 5th generation stealth fighter designed to replace a wide range of existing aircraft, including AV-8B Harriers, A-10s, F-16s, F/A-18 Hornets and United Kingdom Harrier GR.7s and Sea Harriers.

Lockheed Martin is developing the F-35 Lightning II with its principal industrial partners, Northrop Grumman and BAE Systems. Two separate, interchangeable F-35 engines are under development: the Pratt & Whitney F135 and the GE Rolls-Royce Fighter Engine Team F136.

Headquartered in Bethesda, Md., Lockheed Martin employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2006 sales of $39.6 billion.

ho letto che sono ripresi i test sul motore F135 interrotti a maggio a causa di una anomalia che aveva danneggiato il motore. Il primo STOVL F-35B si trova, per l'assemblaggio finale, presso la Lockheed Martin a Fort Worth, Texas, previsto primo volo a maggio May 2008. Si conosce il motivo della rottura che aveva portato alla sospensione del test?

Researchers fine-tune F-35 pilot-aircraft speech system

by John Schutte
Human Effectiveness Directorate

WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFPN) -- When the first F-35 Lightning II rolls out in 2008, communications between pilot and aircraft will enter a new era thanks in part to testing and analysis conducted at the Air Force Research Laboratory's Human Effectiveness Directorate.

The F-35 will be the first U.S. fighter aircraft with a speech recognition system able to "hear" a pilot's spoken commands to manage various aircraft subsystems, such as communications and navigation.

Researchers at the directorate's Warfighter Interface Division are collecting data and recommending improvements now to ensure optimal performance when the F-35's new speech recognition system undergoes future operational tests, said David Williamson, senior crew systems engineer with over 25 years experience with speech recognition technology.

Currently pilots must press buttons, flip switches or glance at instruments for status information. The new system not only simplifies a pilot's workload but increases safety and efficiency, since pilots can remain focused on flying the aircraft and scrutinizing the combat environment.

Using digital recordings from in-flight tests aboard the NF-16D Variable-stability In-flight Simulator Test Aircraft, or VISTA, researchers pinpoint problem phrases and recommend alternatives that are more easily recognized. They also tweak error parameters and adjust the system's sensitivity for peak speech-recognition performance with minimal errors.

To collect data, AFRL electronic engineer Rob Snyder built a custom single-board computer system that plugs into the VISTA instrument panel. Researchers transfer data from the aircraft to the lab's database using a common memory stick.

The speech recognition system is integrated with the aircraft's onboard computer to access data. Communication occurs through the pilot's oxygen mask microphone with command feedback provided on the pilot's helmet-mounted display.

SRI International developed the DynaSpeak® speech recognition software as a highly accurate system for noisy environments, specifically for embedded devices like personal digital assistants, in-car navigation systems and avionics systems, Mr. Williamson said. It is speaker-independent, meaning a pilot can use it without first "training" the system to his or her voice, which took up to an hour on previous experimental systems.

SRI International is working with integrating contractor Adacel Systems, Inc., to tailor the system for the F-35 Joint Strike Fighter's airborne environment.

The AFRL team, including Mr. Williamson, Mr. Snyder and senior scientist Timothy Barry of General Dynamics Advanced Information Systems, worked with six pilots at the U.S. Air Force Test Pilot School at Edwards AFB, Calif., whose primary mission was flying VISTA test-bed sorties to collect speech recognition data.

During typical 90-minute VISTA flights, the system's digital recorder captured the pilot's ongoing dialog with the aircraft. Researchers then returned with the data to the lab where they studied it for troublesome phrases and the impact of environmental conditions, such as ambient cockpit noise or high acceleration forces, which can affect the quality of the acoustic characteristics.

Ambient cockpit noise degrades the quality of the spoken command entering the recognition system, which could cause the system to misinterpret or misunderstand the command. Acceleration forces, expressed in "g," had little impact up to about 6 g, Mr. Barry said.

If the system proves successful on the F-35, it could be applied to other platforms such as the F-22 Raptor, Mr. Barry said.

The system could be advanced enough in less than five years to enable a single ground-based controller to fly up to four unmanned aerial vehicles using voice commands supplemented with gestures or touch-panel commands, Mr. Williamson said.!!!

But first, the Human Effectiveness team wants the F-35 system to be the best it can be, meaning an error rate of less than 2 percent to consider the baseline system optimized.

"We're going to work with the vendor to improve the baseline system for the F-35," Mr. Williamson said. "Collaboratively, we're going to make the system much better before it even gets to the initial operational test and evaluation phase."

Work Starts On Carrier Variant of F-35 Lightning II
BAE Systems | Oct 22, 2007

SAMLESBURY, UK: BAE Systems has started manufacture of the F-35 Lightning II Carrier Variant (CV). The CV aircraft is the final F-35 variant to start production and means that all three variants of the world’s most advanced fighter aircraft are now being produced concurrently by BAE Systems.

The initial manufacturing on the CV variant is of the first titanium and aluminium frames that will form part of the aft fuselage for the first CV aircraft, which is planned to take to the skies in 2009. The aft fuselage and empennage (vertical and horizontal tails) for each F-35 Lightning II variant are being designed, engineered and built by BAE Systems, using the latest in advanced digital design and manufacturing technology.

BAE Systems’ F-35 Lightning II Managing Director, Tom Fillingham said: “Developing three variants of the same aircraft, at the same time, is a first for the military aircraft industry. We are breaking new ground on the F-35 programme.

“Each variant has its own unique challenges that have required some innovative solutions from the team. Now that we have all three variants in manufacture it is great to see all the design and engineering work coming together.”

The F-35 Lightning II programme is the world’s largest defence programme and is currently in the System Development and Demonstration (SDD) phase. The SDD phase will see the production of 21 test aircraft. Fifteen F-35s will undergo flight test, and six will be used for static testing. Another high-fidelity full-scale model F-35 will validate the aircraft’s radar signature. The aft fuselages for all variants of the F-35 are produced at BAE Systems' Samlesbury facility in Lancashire, UK. As production rates increase in the SDD phase, the BAE Systems team is starting a new aircraft assembly every four weeks – a significant achievement for this stage of a development programme.

The three variants of the F-35 Lightning II are being developed to meet the different performance requirements of the US and UK armed forces. The Carrier Variant (CV) is being designed for the US Navy and must cope with the demands of the catapult launches and arrested landings on the large US aircraft carriers. The Conventional Take Off and Landing (CTOL) variant will meet the needs of the US Air Force. Finally the Short Take Off and Vertical Landing (STOVL) variant is being developed to meet the operational requirements of the US Marine Corp and the UK.

BAE Systems is also responsible for the design and delivery of key areas of the aircraft and weapon systems, in particular the fuel system, crew escape, life support system and prognostics health management integration. The company also has significant work share in autonomic logistics, primarily on the support system side, and is involved in the Integrated Test Force, including the systems flight test and mission systems.

BAE Systems is the premier global defence and aerospace company delivering a full range of products and services for air, land and naval forces, as well as advanced electronics, information technology solutions and customer support services. With 96,000 employees worldwide, BAE Systems' sales exceeded £15 billion (US $27 billion) in 2006 on a pro forma basis, assuming BAE Systems had owned Armor Holdings Inc for the whole of 2006.

Lockheed Martin | Oct 29, 2007


FORT WORTH, Texas: Electrical power was applied to the Lockheed Martin F-35B Lightning II for the first time Thursday night, initiating a series of ground tests that will lead to the inaugural flight of the short-takeoff/vertical landing (STOVL) stealth fighter next spring.

"The successful 'power-on' demonstrates that the integration of this unique aircraft is progressing to plan. It signals that production of our first F-35B Lightning II is on track for first flight next year, a key step toward realizing the aviation future of the U.S. Marines, the Royal Air Force and the Royal Navy," said Dan Crowley, Lockheed Martin executive vice president and F-35 program general manager. The aircraft is scheduled to roll out of the factory in December.

The F-35 will be the most electronically advanced aircraft ever built, with capabilities unavailable in current multi-role fighters. The F-35B's power-on is an incremental process of testing the aircraft's circuits, electronic components and wiring.

"This event is one of the major milestones in the life of the STOVL aircraft and we have eagerly anticipated it for some time," said Maj. Gen. C.R. Davis, F-35 program executive officer. "The F-35 has the most complex electrical system of any fighter to date. We had great success with the first jet we flew, but that jet taught us some very important lessons about its electrical system and those lessons have been incorporated into the jet we powered up today. So congrats to the team and on to first flight."

The aircraft incorporates parts and systems from all nine F-35 participant countries (United States, United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway), including the wiring harnesses, produced by Stork Fokker-Elmo of the Netherlands. The wiring harnesses are crucial to the F-35's electrical system, routing and apportioning electrical current throughout the aircraft.

The U.S. Marine Corps and Navy together are planning to operate 680 F-35Bs and F-35Cs, and the United Kingdom plans to place 138 F-35Bs into service with the Royal Air Force and Royal Navy. The F-35B will be the world's first stealth fighter with supersonic and STOVL capability. The first F-35B fleet will go operational in 2012 with the Marines.

The first F-35, a conventional takeoff and landing version, began its flight test program on Dec. 15, 2006.

The F-35 is a supersonic, multi-role, 5th generation stealth fighter designed to replace a wide range of existing aircraft, including AV-8B Harriers, A-10s, F-16s, F/A-18 Hornets, and United Kingdom Harrier GR.7s and Sea Harriers.

JSF: prima accensione dei sistemi della versione STOVL

Giovedì per la prima volta la Lockheed Martin ha "attaccato la corrente" al primo esemplare di F-35B Lightning II, il Joint Strike Fighter (JSF) nella versione short-takeoff/vertical landing (STOVL) che in futuro sostituirà anche gli AV-8B Plus Harrier II della Marina Militare italiana.
L’evento, considerato una pietra miliare del programma, ha dato il via ad una serie di prove a terra per la verifica dei circuiti, dei cablaggi e dei componenti elettronici dell’aereo.
Il successo di questa prima accensione dei sistemi, conseguito anche grazie all’esperienza realizzata sul primo esemplare della versione a decollo e atterraggio convenzionali, fa ben sperare per il rispetto della tempistica del programma anche per questa versione dello Joint Strike Fighter.
Il roll out del primo esemplare dell’F-35B è previsto per il prossimo dicembre, mentre nella prossima primavera dovrebbe essere effettuato il primo volo del velivolo.

La versione STOVL è di gran lunga la piu complessa e problematica.Speriamo bene

Primo rifornimento in volo effettuato

FORT WORTH, Texas --- The Lockheed Martin F-35 Lightning II successfully completed the first stage of its airborne refueling tests during the aircraft's 34th flight yesterday. Aerial refueling capability will expand the F-35 operating envelope enabling longer-duration flights.

The milestone is another in a series leading to first production deliveries in 2010.

"Our progress on the F-35 program remains strong. The F-35 is flying and proving its value every day," said Dan Crowley, Lockheed Martin executive vice president and F-35 program general manager. "The F-35B, the first short takeoff/vertical landing aircraft, is on plan for a mid-2008 first flight. All 19 test aircraft are in manufacturing flow or on the flight line and assembly is under way on the first two production aircraft, which are on schedule for delivery to the U.S. Air Force in 2010."

A specially instrumented KC-135 tanker from Edwards Air Force Base, Calif., is deployed to Fort Worth to support the refueling missions, which will continue over the next two weeks.

"We've known since our first flight in 2006 that the F-35 is extraordinarily stable and controllable, and we've conducted extensive ground testing on the aerial refueling equipment, so it was no surprise that the tests today went smoothly," Crowley said. The tests are designed to evaluate and confirm the operation of the aerial refueling system, procedures and aircraft handling qualities, and are being conducted from Lockheed Martin Aeronautics Co. headquarters in Fort Worth.

On Wednesday's flight, Beesley climbed to 20,000 feet and performed a series of maneuvers to verify the F-35's compatibility with the KC-135's refueling boom and its aerodynamic wake. The sortie also evaluated aircraft systems and handling while connected to the refueling boom. All systems functioned as designed. Beesley reported that the F-35's flight control system provided excellent handling qualities near the tanker, and while connected to the tanker refueling boom.

The Lightning II was aloft for one hour and 34 minutes and completed multiple tanker engagements. "The test team is completely satisfied we can maneuver in the vicinity of the KC-135, and the tanker boom can easily connect with the F-35," said Doug Pearson, Lockheed Martin vice president of the F-35 Integrated Test Force. "We will begin to evaluate the F-35 fuel system during the next refueling test mission by transferring various amounts of fuel from the tanker."



The F-35 carries a prodigious amount of internal fuel -- more than 18,000 pounds -- giving it exceptionally long range without external tanks, and dramatically reducing its need for tanker support. The internal-fuel configuration enables the Lightning II to remain stealthy by avoiding external tank carriage typically used by legacy fighters to extend range. Drop tanks reflect radar energy and can betray an aircraft's location. Operating without drop tanks also frees more stations for external weapons carriage when stealth is not required to fulfill mission objectives.

As the program progresses, international-participant support remains strong. The Netherlands Cabinet recently made a recommendation to Parliament to approve the procurement of two aircraft for operational test and evaluation. The United Kingdom and Italy also are in the process of making decisions on the procurement of test aircraft. All partner nations have parts or systems flying on the first Lightning II.

___________

L’F-35 Lightning II ha completato con successo la prima fase dei test di rifornimento in volo, una tappa importante in vista delle prime consegne del velivolo di produzione nel 2010.
La prova, che si è avvalsa delle precedenti verifiche a terra dei relativi sistemi, ha visto la partecipazione di un KC-135 e si è concentrata sullo studio aerodinamico del comportamento del velivolo nella scia del rifornitore e quando connesso al boom di rifornimento a 20.000 piedi.
Il volo è durato un’ora e 34 minuti durante i quali sono stati effettuati multipli avvicinamenti ed attracchi. Il capo pilota collaudatore Jon Beesley ha sottolineato l’eccellente manovrabilità dell’aereo sia nei pressi del tanker che una volta connesso alla sonda rigida.
I primi test con trasferimento di carburante seguiranno nei prossimi mesi.

JSF: continuano test motore F136

Il team General Electric Rolls-Royce ha completato con successo il programma di sperimentazione ad alta quota, anche con il post bruciatore inserito, del nuovo motore F136 per l’F-35 Lightning II.
L’F136 è il motore "alternativo" per lo Joint Strike Fighter fortemente voluto dal Regno Unito, fu causa di non pochi dissidi all’interno del programma, che sarà in grado di motorizzare tutte le varianti dell’F-35.
I test sono stati condotti con un motore configurato con gli scarichi compatibili sia con la versione Conventional Takeoff and Landing (CTOL) che con quella Short Takeoff Vertical Landing (STOVL); nell’ambito delle prove sono stati realizzati anche lunghi periodi con il postbruciatore attivato.
Nel frattempo un secondo motore F136 sta continuando la sperimentazione al banco presso lo stabilimento della General Electric di Peebles, nell’Ohio; recentemente sono statio completati i test per la versione CTOL, mentre continuano quelli per la versione STOVL.

Northrop inizia assemblaggio del primo F-35 di produzione

Dopo BAE Systems, anche Northrop Grumman ha iniziato l’assemblaggio delle parti di competenza destinate al primo F-35A Lightning II di produzione, cacciabombardiere stealth supersonico multiruolo di 5a generazione, destinato all’US Air Force. In particolare Northrop Grumman, con una settimana d’anticipo rispetto al programma, sta assemblando presso le proprie strutture di Palmdale, California, la parte centrale della fusoliera, partendo dai condotti delle prese d’aria in composito e costruendo attorno ad essi la struttura e integrando i relativi sistemi.
Il blocco centrale, destinato al velivolo AF-6, è il primo che presenta i miglioramenti per quanto riguarda l’ottimizzazione del peso (ridotto del 28% dall’inizio della fase SDD - System Development and Demonstration) e segna la transizione alla fase LRIP (Low Rate Initial Production) del programma Joint Strike Fighter per quanto riguarda Northrop Grumman.
Una volta completata, la parte centrale di fusoliera si unirà alle parti prodotte dagli altri partner industriali presso la linea di assemblaggio finale di Lockheed Martin a Fort Worth, Texas.

L’azienda è responsabile di circa il 25% dei sistemi dell’F-35, fra cui il radar AESA AN/APG-81, la suite di comunicazione navigazione e identificazione (CNI), il DAS (Distributed Aperture System) e vari sottosistemi elettro-ottici.

F35B BF1

[Teox82]

Primo Volo dell’F-35B, la versione STOVL del JSF

L’F-35B, la versione STOVL (short takeoff/vertical landing) del Lightning II, ha effettuato il primo volo con decollo e atterraggio convenzionale presso il complesso Lockheed Martin di Fort Worth, Texas. Ai comandi il pilota collaudatore britannico Graham Tomlinson di BAE Systems, ex pilota di Harrier nella Royal Air Force, il quale ha portato l’F35B a quota 15.000 ft e condotto una serie di test di manovrabilità, variazione di spinta del motore F135 di Pratt & Whitney e controllo dei sottosistemi, prima di concludere il volo dopo 44 minuti.

La prima serie di prove di volo con l’esemplare BF-1 avverrà con decolli e atterraggi convenzionali. All’inizio del 2009 si inizieranno a sperimentare le capacità STOVL con decolli corti, atterraggi verticali e hovering.

“Siamo assolutamente convinti che questo aereo rafforzerà ulteriormente quello che è un enorme vantaggio asimmetrico che noi possediamo in termini di controllo aereo, intelligence, sorveglianza e ricognizione, capacità net-centrica, e la possibilità, se necessario, di rilasciare una bomba in un attacco di precisione “, ha dichiarato il Generale James Conway, comandante dell’ US Marine Corps.

Il velivolo soggetto dei test è il secondo dei 19 esemplari SDD (System Development and Demonstration) ed il primo a incorporare le novità riguardo alla riduzione e ottimizzazione dei pesi che verranno applicate a tutti i futuri F-35.

Quella STOVL sarà la prima delle tre varianti di Lightning II ad acquisire la capacità operativa iniziale (IOC), che verrà raggiunta con i Marines nel 2012.
Con la possibilità di operare da una varietà di navi o di piste semipreparate, F-35B può essere schierato più vicino alla linea del fronte, riducendo la distanza e il tempo di raggiungimento dell’obiettivo, aumentando il rateo di sortite e diminuendo di molto la necessità di assetti di supporto.

L’F-35B sarà il primo aereo STOVL stealth supersonico. Destinato a sostituire gli Harrier AV-8B, GR7, gli F/A-18C/D e gli AMX, entrerà in linea nell’USMC (United States Marine Corps), nella Royal Navy, nella Royal Air Force, nell’Aeronautica e nella Marina Militare Italiana.

L’ F-35B è una delle tre varianti del Lightning II. L’F-35A, versione a decollo ed atterraggio convenzionale ha iniziato il suo programma di test di volo nel dicembre del 2006 ed ha finora effettuato 43 voli superando le aspettative di performance ed affidabilità. L’F-35C, progettato per essere lanciato e arrestato in modo convenzionale tramite catapulte e cavi d’arresto dal ponte delle portaerei della US Navy, farà il suo volo inaugurale nel 2009.
