[HUAG]Francia e Giappone per un nuovo jet supersonico di linea
(Source: Cordis News Service; issued July 1, 2005)
After months of confrontation over who would host the International Thermonuclear Experimental Reactor (ITER), France and Japan are to work together on the design and manufacture of a new supersonic passenger plane to succeed the retired Concorde. The collaboration will begin with three years of research into technologies related to composite material structure, reduction of jet engine noise and other areas currently problematic for supersonic flight. The agreement is between the Society of Japanese Aerospace Companies (SJAC) and the French Aerospace Industries Association (GIFAS), but will also involve research centres and companies from both countries. Japan's Minister for the Economy, Trade and Industry, Shoichi Nakagawa, welcomed the agreement, saying: 'With the steadily intensifying international competition in the commercial aircraft sector, bringing their respective advantages together in order to overcome various technological difficulties should lead to the ability to offer highly advanced aircraft and services in the future. This is truly significant industrial cooperation.' Japan has already successfully tested an engine that can theoretically reach speeds of up to more than five times the speed of sound (mach 5.5), according to the Japanese ministry. For their part, the French will contribute their experience of Concorde, the world's first and only supersonic commercial jet. The partners hope to have the plane in operation by 2015, flying at up to 2.4 times the speed of sound. 'This cooperation programme represents the symbol of the cooperative relationship between the aircraft industries of Japan and France. I am convinced that this programme will stimulate the further development of both countries,' said Mr Nakagawa. ![]()

Forse le moderne normative impongono dei limiti molto più restrittivi di un tempo.

"Un problema importante collegato agli aerei supersonici è il rumore prodotto dai motori degli aerei da trasporto supersonici che è più forte e più acuto di quello dei jet subsonici, già causa di seri disturbi per gli operatori degli aeroporti e per la popolazione residente nelle vicinanze. Serie preoccupazioni sono anche volte agli effetti degli scoppi supersonici (i caratteristici "bang") che vengono prodotti quando le onde d'urto generate da un aereo in volo supersonico oltrepassano l'ascoltatore. Infatti il fronte d'urto che viaggia con l'aereo si estende per elevate distanze verticali e raggiunge il suolo con un impatto che sembra quello di un'esplosione, anche se l'aereo viaggia a quota elevata. L'onda d'urto può essere così potente da rompere i vetri delle finestre. Esistono norme che vietano il volo supersonico sopra le aree popolate." ![]()

..Anche il "Concorde" non poteva atterrare in tutti gli aereoporti a causa di queste limitazioni(sul rumore),se ricordo bene...,come ricordato da Spike...

Quindi passava in supersonico solo sull'acqua, cosa che gli riduceva l'autonomia, essendo ottimizzato per volare in supersonico. Il rumore dei motori mi sembra una scusa colossale trovata da qualche pseudoambientalista per contestare, tanto qualunque scusa va bene. Trovati vicino a qualche pista quando decolla un cargo russo e vedi cosa vuol dire motori rumorosi. Tempo fa ho letto su un giornale che la Boeing sta studiando motori che non fanno il bang sonico. Capisci che dopo aver letto una cosa (e' un eufemismo) del genere, prima di credere a qualunque cosa venga detta o scritta sul rumore dei motori ci penso 42 volte e poi ci credo poco.

O forse era il giornalista ![]() Sai, associare rumore - motore e' piu' facile e fa piu' notizia. Parlando di rumore, e' OT, ma credo che nessuno si lamentera'. Questa e' la lettera inviata da un idiota all'Arizona Republic. ------------------------------------ A wake-up call from Luke's jets Jun. 23, 2005 12:00 AM "Question of the day for Luke Air Force Base: Whom do we thank for the morning air show? Last Wednesday, at precisely 9:11 a.m., a tight formation of four F-16 jets made a low pass over Arrowhead Mall, continuing west over Bell Road at approximately 500 feet. Imagine our good fortune! Do the Tom Cruise-wannabes feel we need this wake-up call, or were they trying to impress the cashiers at Mervyns' early-bird special? Any response would be appreciated." ------------------------------------ E questa e' la risposta del comandante della base, che allo stesso tempo e' un classico e dimostra la sua professionalita'. ------------------------------------ Regarding "A wake-up call from Luke's jets" (Letters, Thursday): On June 15, at precisely 9:12 a.m., a perfectly timed four-ship of F-16s from the 63rd Fighter Squadron at Luke Air Force Base flew over the grave of Capt Jeremy Fresques. Capt. Fresques was an Air Force officer who was previously stationed at Luke Air Force Base and was killed in Iraq on May 30, Memorial Day. At 9 a.m. on June 15, his family and friends gathered at Sunland Memorial Park in Sun City to mourn the loss of a husband, son and friend. Based on the letter writer's recount of the flyby, and because of the jet noise, I'm sure you didn't hear the 21-gun salute, the playing of taps, or my words to the widow and parents of Capt. Fresques as I gave them their son's flag on behalf of the president of the United States and all those veterans and servicemen and women who understand the sacrifices they have endured. A four-ship flyby is a display of respect the Air Force pays to those who give their lives in defense of freedom. We are professional aviators and take our jobs seriously, and on June 15 what the letter writer witnessed was four officers lining up to pay their ultimate respects. The letter writer asks, "Whom do we thank for the morning air show?" The 56th Fighter Wing will call for you, and forward your thanks to the widow and parents of Capt. Fresques, and thank them for you, for it was in their honor that my pilots flew the most honorable formation of their lives. Lt. Col. Scott Pleus CO 63rd Fighter Squadron Luke Air Force Base

A tal proposito...
NASA Funds Studies for Quieter Supersonic Boom (Source: NASA; issued July 8, 2005) WASHINGTON --- NASA and industry teams are studying how to design and build an airplane that could demonstrate technology to lessen the noise and window-rattling effects of supersonic flight. Each team was awarded approximately $1 million for a five-month study. NASA will use the results to define technology and design requirements for a low sonic boom demonstration aircraft. The research will determine whether it's feasible to modify an existing aircraft or to design a new one as the quiet boom demonstrator. "NASA plans to develop a request for proposals to design and build a low sonic boom demonstrator using the information provided by the teams," said Sonic Boom Mitigation Demonstration Project manager Bob Meyer at NASA's Dryden Flight Research Center. NASA awarded a grant to American Technology Alliances to fund these studies. They will be conducted by four industry teams. The teams include solo endeavors by Boeing Phantom Works, Long Beach, Calif. and Raytheon Aircraft, Wichita, Kan. Northrop Grumman, El Segundo, Calif. is working with Gulfstream Aerospace, Savannah, Ga., and Lockheed Martin, Palmdale, Calif. teamed with Cessna Aircraft Company, Wichita, Kan. The same grant is funding Allison Advanced Development Company, Indianapolis; GE Transportation, Cincinnati; and Pratt and Whitney, Hartford, Conn. to support the teams with engine-related data. The Sonic Boom Mitigation Project could begin work on the research aircraft as early as this fall. "It is one element of a transformed Vehicle Systems Program (VSP) in which breakthrough technologies are carried forward to flight," said Rich Wlezien, NASA's VSP manager. NASA's Aeronautics Research Mission Directorate manages the program. ![]()
