Space Shuttle Landing Speed

Sat May 24, 2008 11:04 pm

Hi Everyone,

Reading an interview with a former Space Shuttle pilot who said that basically the Space Shuttle is "falling rather than flying" I was wondering what is its landing and stall speed? The landings don't seem too spectacular but then again they are performed on a 15,000ft runway.

Any ideas?

Don't know about stall speed but I believe the touchdown speed is 200 knots or just over. Not too long ago I saw a video taken from the cockpit when it landed, it was interesting watching the altitude and knots as it approached, not too far from where I live in Daytona Beach.

As far as the approach angle and speed, the astronauts train by taking up the NASA GII to altitude, engage the thrust reversers and that apparently gets them a pretty good idea of what to expect.

I'm sure Thorny can expand or clarify on what I've said  Wink .

"The orbiter's main landing gear touches down on the runway at 214 to 226 miles per hour, followed by the nose gear."

No clue about stall speed, though.

Doesn't look like there is a 'SET' speed:

I'm guessing that for those of us not flying it for real, the number is wholly irrelevant unless we are trying our best to simulate it. I usually get it down @220 in FSX, but I have planted short a few times too. I really would like to get a copy of X-plane to do this better.

MLG touchdown speed depends on Orbiter weight.

There's no simple answer on the stall speed.

It doesn't say GMTA anywhere in that link... I'm confused.

Ted and I posted the same link at more or less the same time.

Ah, thank you for clearing that up. I read the whole damn link trying to find GMTA. Good read though.  Smile

If I get the shuttle's delta wing right it's kind of like an aircraft with a front canard. Like the Beech Starship or a Vari-eze. If you go too slow, the front of the wing loses lift before the rear part and the nose pitches down, gaining you speed. So, you the wing doesn't stall all at once like a conventional wing. The Shuttle is also somewhat of a lifting body, which makes the effect even more pronounced.

This site has some good video clips of launch and landing. Some of them have unedited crew communications. One of my favorites from this site is the shot from the launch tower.
