Propulsion Integration — Quiz

Test your understanding of propulsion integration with 5 practice questions.

Practice Questions

Question 1

Which term describes drag arising from the intersection of aerodynamic surfaces such as the wing and engine pylon?

Question 2

An engine inlet has a total pressure recovery of 0.98 at cruise. If the free-stream total pressure is $P_0$, what is the total pressure at the compressor face?

Question 3

When a turbofan engine ingests the fuselage boundary layer through an aft-mounted inlet (boundary layer ingestion), the overall aircraft drag is expected to:

Question 4

Nozzle plume impingement on downstream airframe surfaces typically causes:

Question 5

At cruise, pylon-shadowing reduces the local dynamic pressure at the inlet by 5%, lowering mass flow. If ideal mass flow is $\dot m$, what is the installed mass flow?
