Fundamental Of Flight Flashcards
Acceleration
Change of speed
Motion
Act of or process of changing position
Speed
Distance measured in a set time
Velocity
Speed of obj in a given time and distance
Newton first law
Obj in motion or rest will cont until acted upon by outside force
Bernoulli principle
Speed of Fluid through constriction is increased as its pressure decrease
Lift
Force acting in upward direction
Weight
Gravity acting down
Drag
Force holds plane back
Thrust
Force made by engine to propel it forward
Longitudinal axis
Roll
Runs nose to tail
Ailerons
Lateral axis
Wing to wing
Pitch
Elevators
Vertical axis
Runs from top to bottom
Yaw
Rudder
Cycle stick
Rotor
Roll/pitch
Tilt rotors forward aft or sideways
Tail rotor
Helo
Yaw
Counteracts torque of main rotor w horizontal thrust
Flaps on a helo
Leading trailing edge
Helo makes extra lift
Spoiler
Decrease wing lift
Speed brakes
Hinged surface used to reduce speed
stats
Located on leading edge improve lateral control at low air speed
Collective
Rotor blades change collectively to change angle of lift
Angle of attack
Angle airfoil or fuselage meet air
Measured in units
Autorotation
Let’s helo land safely wo using engine power
Basic aircraft hydraulic system
Reservoir to hold hydraulic fluid Pump to move fluid Tubing to transmit fluid Selector valve to direct flow Actuating unit to convert fluid pressure into useful work
Landing gear component
Shock strut assembly absorb shock
Tires lets plane roll
Wheel brake assembly Slow and stop plane
Retracting and extending mechanism puts out landing gear
Side strut and support Gives Strength/support for landing gear
