NIFE Aerodynamics Questions - Answered with Correct Answers Which of the following, when doubled, will cause the greatest increase in lift? a) Velocity b) Coefficient of lift c) Density d) Area At zero degrees angle of attack and positive velocity, a symmetrical airfoil will produce: a) Lift, but less than a positively cambered airfoil b) No form drag c) No induced drag d) No net aerodynamic force Still produces parasite drag (because it is at a positive velocity), but the airfoil will produce...

NIFE Aerodynamics Exam - Questions and Answers What is turbulent flow? Disorganized with large amounts of friction drag. Adheres to surface What is the adverse pressure gradient in regards to the boundary layer? From high pressure to low pressure (works from trailing edge to leading edge) What happens to the adverse pressure gradient with a high AOA and kinetic energy decrease? Adverse pressure gradient increases and allows for boundary layer separation (not desirable) What is a stall? Conditi...
