SIFT Army Aviation questions with 100% correct answers graded A+ Airfoil - correct answer Blade that cuts through air so that air passes above and below it Top of an airfoil is ________ - correct answer Cambered Why is the top of an airfoil cambered? - correct answer To allow air to quickly get past the airfoil and create low pressure What happens to the air below the airfoil? - correct answer Has a shorter distance to travel and is slower, creating high pressure Lift - correct answ...

SIFT Army Aviation What are the 3 types of drag? - correct answer Parasite Drag, Induced Drag, Profile Drag Profile Drag - correct answer Type of drag caused by the separation of boundary layers and increased friction on airfoils. Dependent on the shape of the aircraft. Parasite Drag - correct answer Type of drag that acts on an object, creating friction when the object is moving through liquid (a.k.a, the atmosphere.) Induced Drag - correct answer Type of drag that occurs when airfoil...
