Windowless Jets Faster Than Sound! Mach 1.8 - Travel Times Halved.

Spike Aerospace is building what it hopes will be the world's first supersonic business jet, one capable of traveling at Mach 1.8. The S-512, expected to launch in 2018, could cut travel time in half.
But what about the sonic boom problem!? :confused:

      One helluva speedy tin can though! And probably only for the super rich because a commercial sized aircraft would be far too noisy. Thunderclap explosions above.

      Mach 1.8, only 5 years away? I'm in!

    Well, I have been told there is an FAA law limiting civilian flight over most land to .8M.

    Planes often CAN go over Mach 1(Maybe as fast as just under 1.2M under some circumstances) and DON'T.

    Supposedly the reason is to limit sonic booms. When I was a kid, I would hear sonic booms like ALL THE TIME! In the past like 30 years, I think I only heard it like ONCE, and it turned out the shuttle was redirected over where I worked.

      I thought the space shuttle had a double boom? The nose and tail are spaced further apart so you get that delayed effect with the double shock wave.

      I love the sonic boom write up on the NASA site - the Armstrong Fact Sheets.

        It does, but I meant one occasion. STILL, it is usually like the concordin that it comes into a certain area made for it, at least it DID!

    This story reminds of a short-story I once wrote featuring a ridiculous guy who lives in a hi-tech house without windows, since he got better resolution on his computer screens.

    "It sounds like a claustrophobe's nightmare, though Kachoria has attempted to compensate for the windowless design by installing flatscreens, which can either display the view outside, or can be used to show a movie or PowerPoint presentation -- should a conference need to take place in the air."

    If it has no windows how do the pilots steer the darn thing? :confused:

      Well, the front is BOUND to have some problems ANYWAY. I guess that isn't as big of a difference. STILL, look at the concord with the way the nose is, etc...

      The pilots have a window right at the front of the plane. Passengers see the outside world via flatscreens from what I know.

    One of the major problems with early jets was metal fatigue around the windows. That is the reason why all the corners are rounded now. IRONIC, HUH!?!!?!? They are talking about FULLY getting rid of one of the earliest primary problems!

    Regulations against sonic booms are only over the continental US.

    Gun control means never having to say, "I missed you."

      The designers were not interested in a large part of the US market then. Or, New York to LA, go the long way 'round. Could work!?
