AVIT 323 Exam Questions and answers with complete solutions Latest Updated 2025 |
Verified
In one sentence, define induced drag and be very specific - ✔✔The aft-acting component of lift
What is parasite drag? - ✔✔Any drag that is not caused by the production of lift
What is the boundary layer? - ✔✔Layer of air over the surface which shows local retardation due to
viscosity
What are the 3 sections in the boundary layer? - ✔✔Laminar, Transition and Turbulent
Explain sphere of influence - ✔✔High aspect ratio changes the airflow minimally
See circles
What happens to induced drag as aspect ratio goes up? - ✔✔Induced drag is decreased (less down-
wash) the longer the wing the easier the aircraft has to work to produce lift
What happens to induced drag as weight goes up? - ✔✔Increases induced drag
What happens to induced drag as speed goes up? - ✔✔Induced drag goes down
What happens to induced drag as altitude goes up? - ✔✔Induced drag increases
What happens to induced drag as lift increases? - ✔✔Induced drag increases
Why are wingtip vortices included in induced drag? - ✔✔They are induced drag because they are
formed due to the production of lift.
