The LAPCAT A2 is a proposed jet that could whisk passengers around the globe at a dizzying 6100km/h, about five times the speed of sound.

The A2 project - ponderously titled Long-Term Advanced Propulsion Concepts and Technologies (LAPCAT) - was funded by the European Space Agency, which challenged scientists to produce a commercial jet using space-travel technology.

Supersonic aviation as a workable model may have ended prematurely with the death of the Concord, but that didn't stop other people from attempting to bring back the hypersonic civil transportation. The LAPCAT project is a study, funded by Europa General R&D, that seeks to determine whether or not it is possible to create a plane that can cover long distances in a very short amount of time. The result? The A2 Mach 5 Civil Transport Concept.

Aside from being fast, the new jet would also be clean and green, burning a liquid-hydrogen fuel that gives off water vapor and nitrous oxide (laughing gas), instead of polluting carbon emissions. At 142 meters in length, the A2 would be about twice the length of the Airbus A380, the largest airliner in service today.

The term hypersonic flight relates to speeds above Mach 5, a velocity at which friction can cause an aircraft's wings to heat to 1000C.

Unfortunately, attaining such external temperatures would mean doing without windows, but designers may put flat-screen televisions where the windows would be, giving the impression of seeing outside.

Despite being capable of traveling at twice the speed of its predecessor, The Concorde, the A2 would be quieter. Senior engineer and managing director Alan Bond said the A2 could be here within 25 years.

At that speed they've been, gone, come back again and are fondling the stewardesses as we speak.

The pilots fly with monitors, too?

What ever happened to the old sub-orbital transport designs?
30 mins to opposite point on Earth kind of inter-continental people missiles.

Sadly the time when we have fuel enough to run such things economically is on the wane.

Those suborbital planes can not be used for pasenger flight at all, It would generate 4G to get to that altitude atleast.

Even with this aircraft that almost does Mach 6 the G-forces involved would cause the pasengers verry much disconfort, people could even die if that had acardio problem.

I dont think its reall purpes is passengers, but more as display of technology or worse, a cover up for a new kind of strategic bomber.

Also i seen images of that aircraft before but if i remember corectly it had a difrent name than.

That's the same buggaboo that will prevent rapid acceleration to light speed
in a theoretical starship.
To reach C1 it would take nearly exactly one year
at 1G acceleration.
So if you have developed an improbability drive to break the speed of light it will take 4 years of accel and decell on a round trip (not including the trip time!).
Exteded periods at over 1.5G are thought to be fatal no matter
your physical condition.

P.A.

Is there Gravity in Space? Just asking how that works?

How about something at the completely opposite end of the spectrum

http://www.abc.net.au/news/stories/2008/02/07/2157295.htm

The Japanese are going try to land paperplanes from space.

I reminds me of the old film "the mouse that roared" where an obscure little country beat the US into space by making launching a rocket that went too slow to burn up on re-entry!

It's relative. http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

If your inside a rocket with no external clues, the ship accelerating at 10 meters a second per second will be indistinguishable to being in Earth's gravity. To an outside observer, your moving rapidly, but to your perspective, you would walk around, jump or bounce a ball on the wall like normal.

This may help you get started. Approach it with an open mind, and be prepared to throw out some preconceived notions so you can be as confused as the rest of us. http://forums.ubi.com/images/smilies/35.gif

The improbability drive doesn't work like that. Theres no acceleration at all. It works by the fact that it is highly improbable that all points in the universe are actually sharing the same location at the same time. By creating an enormous 'improbability field' powered by a 'Brownian Motion' generator, such as a nice hot cup of tea! (itself highly improbable on british rail or in the low pressure environment of a spaceship!) You just happen to be in the same location as where you want to go! Which is a very lucky coincidence and highly unlikely. Very improbable as you might say!

My error Skoshi, I forgot to mention the tea.... http://forums.ubi.com/images/smilies/88.gif
At a constant acceleration of 1G the people onboard the fantasy starship would feel the same effects
as 1G on earth with down being the direction of the engines outlet.
Stop accelerating and there would be zero G.

But there is gravity everywhere in space, there is never any escaping it.
