Question

Corner speed is defined as __________

(a) velocity for maximum instantaneous turn

(b) maximum lift velocity

(c) maximum aerodynamic efficiency

(d) minimum instantaneous turn speed

This question was addressed to me in an internship interview.

This interesting question is from Flight Mechanics topic in chapter Performance and Flight Mechanics of Aircraft Design

Answer 1

Right answer is (a) velocity for maximum instantaneous turn

The best I can explain: Velocity for maximum instantaneous turn is termed as corner speed. Corner speed is defined by intersection of the stall limit and the Structural limit. For a typical fighter, corner speed can vary between 300 to 350 knots.
