Block XIV- Fundamentals Of Flight Flashcards
What is acceleration
The rate of change of the speed and or velocity of matter with time
What is speed
The rate of movement in terms of distance measures in an allotted amount of time
What is velocity
The quickness of speed of an object in a given time and direction
What is Newton’s first law
(Inertia) an object at rest will stay at rest or an object in motion will stay in motion at the same speed.
What’s Newton’s second law
(Force) the change of motion is directly proportional to the amount of force and inversely proportional to the mass of the object being moved
What is Newton’s third law
(Action and reaction) every action there is an equal and opposite reaction
What is Bernoulli’s principle
When fluid flowing through a tube reaches a constriction the speed of the fluid passing through is increased as pressure is decreased.
How is lift accomplished
By the difference in the airflow across the air foil
What is lift
The upwards force that supports the aircraft in the air. Counteracts weight
What is weight
Force of gravity acting downward on the aircraft
What is drag
The force that hold the aircraft back. Drag resists motion
What is thrust
The force developed by the engine acts in the forward direction
What is the imaginary reference line running down the center of the aircraft between the nose and tail
Longitudinal axis
What is the lateral axis
And imaginary reference line running parallel to the wings
What is the imaginary reference line that runs from the top to the bottom of the aircraft
Vertical axis
What flight control controls roll on fixed wing and rotary wing aircraft
Ailerons (fixed wing) Cyclic stick (rotary wing)
What flight control controls pitch on fixed wing and rotary wing aircraft
Elevators (fixed wing) Cyclic stick (rotary wing)
What flight control controls yaw on fixed wing and rotary wing aircraft
Rudder (fixed wing) Tail rotor (rotary wing)
What does a flap do
Creates extra lift
What does a spoiler do
Decreases or spoils wing lift by destroying smooth flow of air over the wing
What do speed brakes do
Movable control surfaces that reduce the speed of the aircraft
What does the tail rotor do
Counteracts the torque of the main rotor with horizontal thrust
What do slats do
Allows the aircraft to be controlled at airspeed below normal landing speed
What does AOA stand for
Angle of attack
What is the angle of attack
The angle of the airfoil or fuselage meets a flow of air. Aids with landing
What is auto rotation
A method of allowing a helicopter to land safely from altitude without using engine power
What are the five basic parts of the hydraulic system
Remember PARTS Pump Actuator Reservoir Tubing Selector valve
5 Main components of the landing gear
Shock strut Tired Wheel brake assembly Retracting and extending mechanism Side struts and supports
What does a shock strut assembly do
Absorb the shock when landing
What is motion
The act or process of changing place or position Motion is movement
