Question

What is meant by static thrust?

(a) thrust at maximum airspeed

(b) power at zero airspeed

(c) thrust at zero airspeed

(d) power at maximum airspeed

I have been asked this question in an online interview.

This interesting question is from Power Producing Power Plant in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Correct choice is (c) thrust at zero airspeed

For explanation I would say: Static thrust is the thrust at that is produced at zero airspeed. This static thrust decreases with the increase in airspeed of a power-producing engine. This condition arises when propulsive increases with decrease in airspeed.
