AVIT 323- Block 10 Test UPDATED Exam
Questions and CORRECT Answers
Drag - CORRECT ANSWER - Component of aerodynamic force parallel to relative wind
and retards the motion of the aircraft
Parasite Drag - CORRECT ANSWER - Not associated with lift, displacement of air by
aircraft
Induced Drag - CORRECT ANSWER - Drag that results from production of lift
Pressure difference from upper and lower wing surfaces
Shockwave Drag - CORRECT ANSWER - Shockwave formation at high airspeeds
Skin Friction Drag - CORRECT ANSWER - Aerodynamic resistance due to conflict of
moving air with surface of aircraft, does not matter how smooth air surface is
Increase Skin Friction Drag - CORRECT ANSWER - Wetted Surface= airfoil that has
direct contact with atmosphere
Amount of Viscous Drag in Boundary Layer= airflow local reduction due to viscosity
Velocity
Reduce Skin Friction Drag - CORRECT ANSWER - Flush mounted rivets
Smooth finish
, Wax
Form Drag - CORRECT ANSWER - Drag generated by shape of aircraft and components
(net force develops and opposes flight path)
Reduce stream lining (less form drag and increase skin friction)
Profile Drag - CORRECT ANSWER - Result of skin friction and form drag an airfoil
creates
Drag Bucket= low AOA, coefficient of drag is reduced/ high AOA produce separation and
increase coefficient of lift
Interference Drag - CORRECT ANSWER - 2 airstream that intersect and create turbulence
and restrict smooth air flow
Reduce Interference Drag - CORRECT ANSWER - Surface do not meet 90 angles
(fairings), increase distance between lifting surfaces and external components
Cooling Drag - CORRECT ANSWER - Produced in the cooling process of a engine, sum
of skin friction and form drag
Calculating Parasite Drag - CORRECT ANSWER - Ratio of drag pressure to dynamic
pressure
Equivalent Parasite Area - CORRECT ANSWER - Found by placing aircraft at AOA
produces zero lift, parasite drag remains
Factors Influence Parasite Drag - CORRECT ANSWER - Velocity
