Question

Linearized pressure distribution for higher deflection angle is inaccurate.

(a) True

(b) False

This question was addressed to me by my school principal while I was bunking the class.

I'd like to ask this question from Linearized Pressure Coefficient in chapter Linearized and Conical Flows of Aerodynamics

Answer 1

Right choice is (a) True

The explanation is: The linearized pressure distribution is usually inaccurate for higher deflection angles beyond 4 degrees. But when they are integrated to obtain the linearized coefficient of lift and drag, the inaccuracies are approximately compensated when adding the upper and lower surface.
