Question

What is thrust matching?

(a) Comparison of the engine’s available thrust at cruise to the estimated drag of aircraft

(b) Comparison of the engine’s available thrust at cruise to the estimated weight of aircraft

(c) Comparison of the engine’s available lift at cruise to the estimated drag of aircraft

(d) Comparison of the engine’s available power at cruise to the estimated drag of aircraft

This question was posed to me in an interview for internship.

The question is from Thrust Weight Ratio-2 in section Thrust-Weight Ratio and Wing Loading of Aircraft Design

Answer 1

Correct answer is (a) Comparison of the engine’s available thrust at cruise to the estimated drag of aircraft

For explanation I would say: Thrust matching is nothing but the comparison of an engine’s available thrust at cruise to the estimated drag of aircraft. It is used for better initial estimation of the thrust to weight ratio.
