Odd question for any aerodynamics experts

[Echo38]

I'm afraid I don't understand half of that. What's CD?

[Exorcet]

CD is the drag coefficient.

 

To recap what I said:

 

Find the structural limit of the plane, you can estimate from the never exceed speed. Convert this speed into true airspeed and plug into the formula for dynamic pressure

 

https://en.wikipedia.org/wiki/Dynamic_pressure

 

That will be the limit that the aircraft can't exceed.

 

With the terminal velocity calculator and a chart for density at different altitudes, find the terminal velocity at a given altitude, then use this terminal velocity to compute a dynamic pressure. If this terminal dynamic pressure is greater than the never exceed speed dynamic pressure the plane can accelerate to dangerous speeds from gravity alone.

Structural damage, no suitable method of control, no way to control the plane when decelerating through Mach 1.

 

But to be cheeky, by inference, if heating doesn't occur, then friction can't exist, which means that none of the 4 fundamental forces exist and the universe will fall apart.

Well we could imagine that the aircraft is made of some super heat resistant material ;) Yay! Universe saved :D

But then it wouldn't be a WWII fighter if it had ceramic composite skin and prop. I honestly can't imagine where this question originated from.

I think the point is to try to understand aerodynamics a little better. Overblown unrealistic scenarios for thought experiments tend to be very effective at exploring ideas as the conclusions tend to be quite clear if there is any.
