AVIT 323 Final Exam- Dilse Questions
And Answers
High lift devices -
correct answer ✅✅✅Flaps, slats, slots
Definition of a stall -
correct answer ✅✅✅Exceeding the critical angle of attack
Coefficient of lift -
correct answer ✅✅✅-The ratio between dynamic pressure and
lift pressure
DOES NOT CHANGE WITH:
-Weight
-CG
-Aircraft pitch attitude (think AOA)
-Or Aircraft weight
Angle of indicence -
correct answer ✅✅✅Chord line related to the longitudinal axis
Negative AOA -
correct answer ✅✅✅More lift on the bottom of the airfoil
, AVIT 323 Final Exam- Dilse Questions
And Answers
Positive AOA -
correct answer ✅✅✅More lift on the top of the airfoil
AOA differs with -
correct answer ✅✅✅›Pitch Attitude
›Altitude
›Weight
›Speed
High density altitude -
correct answer ✅✅✅High altitude, air is thinner so lift is
decreased
Low density altitude -
correct answer ✅✅✅Low Altitude, thick air, good for flight
performance.
Types of parasite drag -
correct answer ✅✅✅-form drag (Separation drag)
-skin friction drag (viscus drag)
-Interference drag (produces two boundary layers 1+1=3)
