The value of ‘n’ in fuel flow formula C=C2\(\theta^{\frac{1}{2}}\)M^n is 0.6 for turbojet.(a) True(b) FalseThis question was addressed to me in an international level competition.I want to ask this question from Cruising Performance topic in portion Cruising Performance of Aircraft Performance

Answer» RIGHT choice is (b) False

To explain I would say: The correct formula for fuel flow is C=C2\(\THETA^{\frac{1}{2}}\)M^n where θ is the temperature, M is MACH number and n varies from 0.2-0.6 for TURBOJET to turbofan. It depends on the bypass RATIO of the combustion chamber.
