Question

What is the value of minimum power speed when minimum drag speed is 300m/s?

(a) 173.21 m/s

(b) 227.95 m/s

(c) 134.16 m/s

(d) 200.62 m/s

This question was posed to me by my college director while I was bunking the class.

My question comes from Aerodynamic Relationships topic in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Correct choice is (b) 227.95 m/s

The best explanation: The correct answer is 227.95 m/s. Given Vmd is 300m/s. From the formula Vmp=\(\frac{1}{\sqrt[4]{3}}\)Vmd substitute the values.

On substituting we get, Vmp=\(\frac{1}{\sqrt[4]{3}}\)*300

Vmp=227.95m/s.
