aeroheating
is there any guidelines on the levels of aeroheat generated at various airspeeds? i am interested in bodies travelling between mach 2 to mach 5 and the aeroheating that they would be subjected to. would there be any sigificant differences between the leading edges and planar surfaces. any advice would be greatly appreciated. eng-tips forums is member supported. quite simple mach number calculations: t_0/t = 1 + [(g-1)/2]*m^2 where t_0 is stagnation temperature, t is static (ambient) temperature, m is mach number, g is specific heat ratio. g can be approximated by (n+2)/n where n is the degrees of freedom of the gas, which increases with temperature. for room temperature, diatomic conditions n=5, g=1.4. i think g~1.2 for re-entering apollo command modules. dig around nasa's website for historical stuff about the x-15. i re you might also simply peruse the many government lab report servers such as: |
