France and Japan Planning New Supersonic Jet

jonerik writes "According to this article from the Associated Press, Japan and France are cooperating on research to produce a supersonic passenger plane that would be able to carry 300 passengers (three times as many as the Concorde) and fly from New York City to Tokyo in a mere six hours. Current plans are for the plane to be able to cruise at mach 2.4 while reducing the noise and high fuel consumption associated with the Concorde during its years of service. Although Japan had previously done extensive research towards building a 250-person mach 1.6 passenger jet, the agreement with France - announced at the annual Paris Air Show on Tuesday - represents a interesting shift in technological alliances given the Japanese aviation industry's longstanding ties to the United States. 'To research closely in this area with the Europeans does represent something new,' said Yoshio Watanabe, an official with The Society of Japanese Aerospace Companies, which is heading the new initiative on the Japanese side."

    The U.S. aviation industry has no desire to build these aircraft. The FAA prohibits supersoinc flight over US Soil @ any altitude without prior special approval.

      No.

      The bottom line of the FAA directive, states that "no measureable sonic boom overpressure" may reach the surface of the U.S. except within an authorized test area. There is a rather lengthy procedure to be granted such an authorization. There is no mention of altitude in the FAR 91.817 or it's Appendix. The rule simply states that if you make a sonic boom, it cannot reach the surface of the United States.

      In addition, high altitued flights are generally regarded as a Bad Idea because of concerns of radiation.

      100 km is also 62 miles. A decent from such a flight will certainly put an aircraft above mach 1 over at an altitude which will cause a sonic boom to reach the US.

    I don't think US carries have ever been that interested in supersonic aircraft. One of the biggest hurdles is the prohibition against going supersonic over land which would drasictally limit the number of possible routes. I would make sense for Japan to do such research in that much of thier flying time would be over water anyway. I will be interesting to see if this actually catches on though. Boeing was working with the Russians for a while and nothing panned out there. Nor did anything pan out on the mach .98 plane they were designing.

    Its because large scale technological advances aren't marketable. I mean, ultimately that's why the Concorde project was left to die out. The costs associated with maintaining the Concorde was prohibitive, so they just peacefully let it die.

    The technological advances are still being attained at a good clip, but we don't see them because profit margins are maintained by being safe and marketable while calling yourself "innovative", not by actually being innovative. Its part of the reason people want to get rid of NASA, because it doesn't give the masses something easily consumable like a "War on Terror" or welfare or porn or the internet or whatever...

    The $1.8 Million investment should indicate that this is just a study, and that it's probably a lot of hype for whatever reason at the most famous air show in the world.

    Seeing Japan and France in the news together also makes me wonder if this is meant to assuage some of the bust up over the iter reactor.

    Another post mentions that there's no interest in the US in a supersonic jet, because of restrictions over land. This says nothing of Reagan's old Orient Express hypersonic proposal, or the basic desire to furnish jets for overseas flight.

    Look at it from another perspective... What does the US bring to the table, any more. G.E.'s new jet engine research facility is in India. US software jobs are migrating to India, and the semiconducter industry has been migrating to the Far East for over a decade. We're even starting to oursource our weapon systems. "If present trends continue," (and I'm hopefully quoting Lester Thoreau of MIT on this) by the time the keel is laid on any supersonic jet, the only thing the US will have to offer is overpaid executives.

    I agree with your general thrust, except for point 3.

    The engineering goals (efficiency @ speed @ altitude) dictate certain design parameters -- wing shape & area, fuselage size, engine design, etc. The problem is, an airplane designed to fly for 10,000 miles at mach 1.6 at 50,000 feet is *not* going to fly efficiently at subsonic speeds. So, alas, no, the pilot won't be able to just "throttle down" for 3000 miles... it would make the plane vastly more expensive to operate.

    Concorde had the safest flight record of any commericial plane. The more ironic thing is that concorde crashed because a piece fell of a different plane, and the debris was lieing on the runway, punctured the tire which ripped into the underside of the wing causing a massive fuel leak which got ignited by the engines and therefore crashed and blew up.

    Remember more people die per year on Britains roads alone than the total number of air crashes per year. It is by far the safest method of travel.

    These long jumps are the place for supersonic travel. With the hours of overhead of travel, reducing NYC/Paris from 6h to 2h makes very little of difference: you're still taking a whole day each way. At 600MPH, though, that overhead plus 15h travel winds up taking two days each way. For a trip that's usually a week, which means 4d travel / 7d total = 57%, down to 29%. Which means less time traveling than visiting, rather than the disproportionate reverse. With those proportions, a weekend trip anywhere in the world starts to be worth taking.
