Question

A jet fighter aircraft is flying with maximum Mach number of 2.0. What will be the thrust loading of the fighter?

(a) 0.57

(b) 0.64

(c) 2.5

(d) 2.0

I got this question by my school principal while I was bunking the class.

I would like to ask this question from Thrust Weight Ratio-1 topic in division Thrust-Weight Ratio and Wing Loading of Aircraft Design

Answer 1

Correct option is (a) 0.57

The best explanation: Given, Jet fighter with max Mach number M = 2.0

Now for jet fighter thrust loading is given by,

T/W0 = a*M^c

For a jet fighter a=0.514, c=0.141

Hence, T/W0 = 0.514*2.0^0.141 = 0.566 = 0.57.
