Question

What is the value of ‘n’ exponential in the fuel flow law for a high bypass ratio turbofan?

(a) 0.4

(b) 0.5

(c) 0.6

(d) 0.7

I got this question by my college professor while I was bunking the class.

I'd like to ask this question from Cruising Performance in chapter Cruising Performance of Aircraft Performance

Answer 1

The correct answer is (c) 0.6

Explanation: The value of ‘n’ exponential in the fuel flow law for a high bypass ratio turbofan is 0.6. The value of ‘n’ exponential is directly proportional to the engine bypass ratio i.e. it increases when the bypass ratio increases.
