Block 14 - Fundamentals Of Flight Flashcards
What is motion?
The act, or process, of changing place it position
What are the three types of motion?
Linear: all parts moving in the same direction
Angular: axis of rotation
General: combo of linear/angular
Describe the following terms:
Force
Inertia
Acceleration
Speed
Velocity
Force: causes change in the motion of an object
Inertia: willingness of an object to stay in motion unless moved by an outside force
Acceleration: changes of speed/velocity with time
Speed: rate of movement in distance measured in an allotted time
Velocity: the quickness of an object in a given time
Explain newtons first, second, and third law and Bernoulli’s principle
First: object will rest or stay at the same motion until acted by an outside force
Second: the net of the force on a object to accelerate
Third: every action will have an equal and opposite reaction
Bernoullis principle: when fluid goes through constriction it speeds up
What is:
Lift
Weight
Drag
Thrust
Lift: force that acts in an upward direction
Weight: force of gravity
Drag: force that holds back an aircraft
Thrust: must be greater than drag; acts as forward motion
List the axis.
Lat
Long
Vertical
Lateral
Longitude
Vertical
Ailerons, elevators, rudders, cyclic stick, tail rotor controls what?
Ailerons: longitude
Elevators: lateral
Rudders: vertical
Cyclic stick: roll/pitch
Tail rotor: yaw
Define the aircraft components:
Flap
Spoiler
Speed brakes
Slats
Flap: creates extra flaps
Spoiler: creates a better landing glide slope
Speed brakes: reduces speed
Slats: improves lateral control handling characteristics
Define an airfoil:
Anything that produces lift
Define the different between a fixed wing and helicopter airfoil:
Fixed wing: wings
Helicopter: blades
Define
Collective
AOA
Autorotstion
Collective: produces lift by rotating the blades at a high speed
AOA: angle of attack
Autorotation: a method of allowing a helicopter to safely land without using engine power
Explain the basic aircraft hydraulic systems:
A reservoir for hydraulic fluid
A pump to provide flow
Tubing to transport fluid
Selector valve to direct the flow
An actuating unit to convert the fluid pressure
What’s re the components of the landing gear?
Tires, shock strut assembly, wheel brake assembly, retracting and extending mechanism, side struts and supports
State the safety precautions used when servicing aircraft tires
Highly stressed, approach tires fore and aft, deflate when removing from aircraft
Describe the following engine systems:
Turbojet
Turbo shaft
Turboprop
Turbofan
Turbojet: propels aircraft in opposite or forward direction
Turboshaft: delivers power though shaft through something other than a propeller
Turboprop: turns gas-energy into mechanical power to drive propeller
Turbofan: propeller is replaced by a duct-based axial flow fan
