Question

Which of the following will use suction to divert the boundary layer?

(a) Boundary layer suction

(b) Step diverter

(c) Thrust loading

(d) Power loading curve

The question was asked by my college professor while I was bunking the class.

Query is from Propulsion topic in chapter Propulsion and Fuel System Integration of Aircraft Design

Answer 1

Correct choice is (a) Boundary layer suction

For explanation I would say: Boundary layer suction is one of the type of the boundary layer diverter. Here, the boundary layer air is removed with the help of suction. It doesn’t benefit from the ram impact. Power loading is related to propulsion system performance.
