Supersonic flight is fascinating from many angles, but what I really find fascinating is that the biggest challenge to supersonic flight was actually the TRANSonic regime, that is the transition from subsonic to supersonic, and the opposite. That was one of the hardest things to figure out.

I’m glad you have shown this, I have often relayed to friends about coffin corner from my introduction in CPL training. But I get the “yeah right” look from them! From memory, there have been serious testing issues on aircraft with high tails like VC 10 and Trident etc. I think we were given report sheets to read through but that was 30 yrs ago so I can’t quite remember the details. On losing elevator authority from the shock wave pressure movement, I am sure I read an account of even lowering undercarriage to cause a downward pitch change from the shift of the drag centre line. Thank you..

So many dependencies on dynamic pressure, and how at Mach numbers above about .30, compressibility effects on dynamic pressure impact things like lift and drag. Great video.

Another excellent and informative video, and especially appreciate the demo of what happens as you approach it. I seem to recall reading the the U-2 spyplane spends much of its flight at Coffin Corner, due to the extreme altitude it operates at. BTW - I think Pilot Monitoring needs changing or feeding!

Thank you so much for explaining the coffin corner concept but I do have a question. If the aircraft is getting it’s airspeed from the air going into the pito tube and the air gets thinner the higher you go, How does aircraft determine the mach speed, ground speed and true air speed?
@IamJimhunder
2 жыл бұрын
Would the VLS creep up in a turn? Since the inboard wing will experience a lower airspeed than the outboard wing in a turn? Similarly, would the outboard wing stall? How does the Airbus protect the aircraft in this situation?
@jjsmallpiece9234
2 жыл бұрын
Yes, because the lift vector reduces as you turn the aircraft. So if lift goes down, more speed is required to compensate. Remember Lift (force) = 1/2 ro S Cl
@tomstravels520

I don’t think so because VLS is based off the stall speed of the aircraft at its current weight. Alpha Prot and Alpha Max would creep up but VLS (like green dot) are characteristic speeds

How would you pre plan for cruise altitude for the flight plan? I guess there is a weight/altitude chart or calculator so you don't prefile for 380 and then end up having to request 340, for example?

Hey, I'd still love to get your input sometime (maybe a video about it) about what rudder pedal sensitivity setting to use, or that you're using, to make the Fenix A320 (or any of the mods, I suppose (in msfs)), "feel" most realistic to the actual aircraft. I know, I know, there are many different rudder pedals, etc, but the "standard" sensitivity setting just seems wayyyy too sensitive. Would love your input on this.

@@dgonL why water that have the same temperature as air differ in speed of sound? Both are categorized as fluid and can have varying density (salt water is denser for example). Also it's density that seperates water and air at the same temperature.
@dgonL
2 жыл бұрын
@@bltzcstrnx There are two reasons for this. First of all the formula "speed of sound = sqrt(kappa*r*T)" has kappa and r. These two values change if the fluid changes. So for air they're always the same (kappa = 1.4 and r=287), but water has different values. Secondly, air can be approximated as an ideal gas (truely ideal gases don't exist, but air is very close), water (or steam) on the other hand is not an ideal gas at all. What I'm saying is that, as long as the fluid stays the same, the temperature alone is enough to determine the speed of sound.
