Billy Mitchell Aerospace Test
Questions & Answers| A
Guaranteed
Dynamic Lift - ✔✔Newton's Lift, takes effect when a bird changes its body angle slightly upward to
it's flight path
Induced Lift - ✔✔Bernoullian Lift, pressure difference between upper and lower areas of a bird's wing
Dynamic - ✔✔Force in motion
Daniel Bernoulli - ✔✔Discoverer of relationship between pressure and fluids in motion
Bernoulli's Principle - ✔✔When a fluid accelerates, the pressure drops
Newton's 1st Law - ✔✔An object at rest remains at rest unless acted upon by an outside force
Newton's 2nd Law - ✔✔A force acting upon a body causes it to accelerate in the direction of
the force; acceleration is directly proportional to the mass of the body being accelerated
, Newton's 3rd Law - ✔✔For every action, there is an equal and opposite reaction
Trailing Edge - ✔✔The back portion of an airfoil
Coefficient of Lift Formula - ✔✔Mathematical formula with 5 components: air density, velocity,
wing area, airfoil design, angle of attack
Camber - ✔✔Curved part of the airfoil that goes from the leading edge to the trailing edge
Leading Edge - ✔✔The front portion of an airfoil
Relative Wind - ✔✔The flow of air which moves opposite the flight path of an airplane
Natural Forces of Flight - ✔✔Drag and Gravity
Forces of Flight - ✔✔Lift, Thrust, Weight (Gravity), Drag
Thrust - ✔✔Moves an aircraft forward
Drag - ✔✔Force that retards forward movement of the aircraft
Chord - ✔✔Imaginary Line drawn from the leading edge to the trailing edge of an airfoil
Lift - ✔✔Upward force that opposes gravity
Angle of Attack - ✔✔Angle between the chord line and the relative wind
Critical Angle of Attack - ✔✔The point at which a wing will stall
