Supersonic question.....
Ok… I once asked a question here about Mach speeds vs Stall speeds and got a very comprehensive reply from SNS3GUPPY . No-one growled too much (bloody simmers in our group !) and now something else is keeping me awake at night so I thought I’d try my luck again.
If I trade my (Microsoft Sim) 744 for a Concord and I’m blazing along somewhere close to FL400, at M0.85 thru M0.90 thru M0.95 thru M0.99.
Now Mmo is not going to be a problem for me so now I imagine that I’m flying up against a wall - (pushing the wall). As the afterburners push me thru M1.0 thur M1.1 I imagine that I ‘push thru’ the wall and as the wall moves (relatively slowly) along the length of the aircraft. Eventually, this pressure wave is going to get very close to some important aerodynamic controls (wings & control surfaces)
1. What happens to the aerodynamics of the wing and control surfaces whilst this is happening? (In fairly simple layman’s terms that even a simmer (with some engineering background) would understand).
2. As the afterburners continue to roar and I move to M1.2 and the ‘wall’ moves past the back of the tail of the aircraft am I now beyond the wall ? Do I now, given the same mass/power/attitude, experience increased acceleration up thru M1.5 until I start to feel the effect of the M2.0 wall approaching ?
If you HATE simmers on your forum…. Please ignore this entry.
If it just a silly question (and I should be taking sleeping tablets) – be kind explaining it to me.
