X-43A reach the speed 7700 km/h (7 mach)!
It's sure information from NASA website.

OK! OK! I'm going home... Bye! :backhand:

[Shadow]

7700km/h are 6,48 Mach
Mach 7 is 8316 km/h

[Troll]

Ok. Ok. As i said i'm going home. Sorry.

7700km/h are 6,48 Mach
Mach 7 is 8316 km/h

Depends on altitude. While 1 Ma = 1224 km/h (333 m/s) at sea level, it decreases to 1008 km/h at 10 000 meters.

Where is the PICS?

[Shadow]

No, it has nothing to do with altitude only with tempature and medium (Glas ,Water etc.). But not with air humidity and air pressure.

Air 330 m/s @ 0C°
Glas 5300 m/s @ 20C°

Air 349.23 m/s @ 30C°

And on high attiduides is 20C° :)

This was a typing fault.

Why do you quarrel over this? It is **** fast super quick however you look upon it. :D

What are you trying to say, NASA scramjet is the fastest?
The Aussie scramjet reached Mach 7.6 in 2002 test, beat NASA by
0.6 Mach. Nice try NASA, but no world record for you.

That looks like a missile to me.

Allan Paull of the University of Queensland in Australia is seen on launch day next to the tip of the HyShot vehicle.

The difference is that Australia's project (which is funded by many nations including USA) was just the engine. It was mounted on a rocket which boosted it up and then came down in a parabolic trajectory. However the test was successfull (it reached Mach 7.6 on it's way down).

The X-43 is an actual aircraft that had controlled horizontal flight. So it is the combination of the engine and airframe that makes this test unique and one step further along than Australia's.

EDWARDS AFB, UNITED STATES: Visitors examine the third supersonic X-43A research vehicle (without it's booster rocket) at it's hangar at NASA's Dryden Flight Research Center at Edwards Air Force Base in California's Mojave Desert, 27 March 2004, after the successful launch and test flight of the second X-43A research vehicle. This X-43A is scheduled to be tested this summer, with the aim at reaching Mach 10 (ten times the spend of sound). AFP PHOTO / Robyn BECK (Photo credit should read ROBYN BECK/AFP/***** Images)

The work (HyShot) was limited, however, because the scramjet didn't provide thrust to propel an aircraft.

Nonetheless, Go Aussies!

[Rakki]

...the HyShot program however used a rocket to fire the scramjet up into near-space - in order to REACH hypersonic speeds on the way down. The scramjet aboard produced NO net thrust, and was intended only as a "proof of concept" and to gather data on air densities and such...

Technically, yes. rofl

[Fintin]

face it our rocket has bigger balls

[CannibalSquirel]

face it our rocket has bigger balls

Doesn´t that makes it heavier? rofl rofl rofl rofl
