Term
| Newton's First Law of Motion |
|
Definition
(inertia)
object at rest will stay at rest. object in motion will remain in motion unless acted upon a force |
|
|
Term
| Newton's Second Law of Motion |
|
Definition
(force)
object moving at uniform speed is acted upon by an external force, change of motion, or acceleration, will be directly proportional to the amount of force, inversely proportional to the mass of object.
(or force is equal to the change in momentum) |
|
|
Term
| Newton's Third Law of Motion |
|
Definition
(action and reaction)
for every action, there is an equal and opposite reaction |
|
|
Term
|
Definition
| fluid flowing through a tube reaches a constriction of the tube, speed of fluid passing through construction is increased, pressure is decreased |

Definition
(roll/pitch)
tilts the plane (angle) of the rotor blades forward, aft or sideways. |
|
|
Term
|
Definition
| counteracts torque of the main rotor by increasing or decreasing the amount of horizontal thrust |
|
|
Term
| Flap (leading/trailing edge) |
|
Definition
|
|
Term
|
Definition
| decrease or spoil wing lift by destroying the smooth flow of air. creates more predictable landing glideslope |
|
|
Term
|
Definition
| hinged or movable control surfaces reducing speed of aircraft |
|
|
Term
|
Definition
| movable control surface attacked to leading edge of wing. allows aircraft to be controlled at airspeeds below the normal landing speed |
|
|
Term
|
Definition
| lift is accomplished by rotating the blades through the air at a high speed. lift can be changed collectively increasing angle of attack or pitch of rotor blades. |
|
|
Term
|
Definition
angle which the airfoil or fuselage meets a flow of air
measured in units |

|
Term
| Basic aircraft hydraulic system |
|
Definition
reservoir to hold hydraulic fluid
pump to provide flow of fluid
tubing to transmit fluid
selector valve to direct flow of fluid
actuator unit to convert fluid pressure to work |
