Question

Which of the following is a type of inlet?

(a) NACA flush inlet

(c) Slat

(d) Fuselage

This question was addressed to me at a job interview.

My enquiry is from Propulsion in chapter Propulsion and Fuel System Integration of Aircraft Design

Answer 1

The correct answer is (a) NACA flush inlet

To explain: Inlet has primary function to reduce flow velocity of the incoming air. NACA flush inlet is one of the example of typical inlet profile. Flap and slat are secondary control surfaces. Gisele is main body of an aircraft.
