*** Posted by Rapier *** Hello, I a modern day Airliner were to change direction if it were going at a supersonic speed the wing's would snap off in a second. It is much easier to change altitude and direction in a fighter because they are built in a compact and have a very strong structure to deal with the stresses of G as you well know Run, ...

*** Posted by Rapier *** Hello Run, Of course the F-117 is a stealth aircraft, so aerodynamics suffer with this plane. Designing a supersonic stealth aircraft would not be practical at all because supersonic aircraft send out an excellent heat signature, so it would not make it a steathy plane at all. Very advanced material's would have to be ...

*** Posted by run *** Sometimes you have to compromise, fx when it comes to stealth. The f-117 is not excactly gods gift to aerodynamics. run [Of course, you make a good intuitive comment, but why would any aircraft designer design an aircraft with a high drag factor? Aircraft cannot be designed this way, it would be inpractical to do so. ...

*** Posted by run *** [ ---snip--- 1. Airliners dont have to change course that much in a horizontal way, I meant they have to change altitude in order to avoid other flight's, they will sometimes deviate if there is on-comming traffic and also weather factors come into play when avoiding a thunderstorm for saftey reasons etc. ---snip--- 2. It ...

*** Posted by run *** [---snip--- Most airliners dont go supersonic because they have to change course and deviate in altitude alot of the time. ---snip--- Rapier ] The reason airliners don't go supersonic is because they can't and not because they have to change course a lot. Transatlantic airliners don't turn a lot enroute. The sounlevel in ...

*** Posted by run *** Hi Rapier Size is not always the most important. Shape is way more important. A little object can easily create more drag than a big object with the right shape. run [Put it this way, the bigger the object the more drag there is through air space. You dont need all this mathematical shit it's just the way it is. Regards

*** Posted by Kim Nielsen *** Hi Rapier. You must have misunderstood my letter. I'm not facinated of the sound, but surprised, and interested in the technique around the background why it appears to its standing level such sudden (aproximately within a speed-difference of less than 50 km/t, due to the elapsed time of between 5 and 10 seconds ...
