First, I'd like to express my appreciation for making us old guys (at least this one
) catch up on the more recent developments on the cutting edge of technology.
Glad to be of help.
The original formula read: T= 220(1+ 0.2*Machnumber squared)
Okay the equation would go like this
1.) T
0 = 220 (1 + 0.2(M)^2)
2.) T
0 = 220 (1 + 0.2(5)^2)
3.) T
0 = 220 (1 + 0.2(25))
4.) T
0 = 220 (1 + 5)
5.) T
0 = 220 (1 + 5)
6.) T
0 = 220 (6)
7.) T
0 = 1320 K
In this case, the 220 is the assumed initial (Freestream) temperature Kelvin.
Which I'm guessing is the outside air temperature they're going to be flying Mach 5 at?
