Let us consider the ambient air temperature is 25°C and aircraft has Mach number of 1.5. Find the stagnation temperature.(a) 432.32K(b) 789K(c) 123.56K(d) 213.458KI had been asked this question during an interview.My doubt is from Structures in portion Structures and Loads of Aircraft Design

Answer»

Correct CHOICE is (a) 432.32K

The best I can explain: GIVEN, ambient air temperature T1 = 25°C = 25+273.15 = 298.15K, MACH NUMBER = 1.5

Stagnation temperature for air is given by,

Stagnation temperature = T1*(1+0.2*M^2)

= (25+273.15)*(1+0.2*1.5^2) = 432.32K.
