Flight/NAMP/AIMD/NALCOMIS/NATOPS Flashcards
Acceleration?
Rate of change of the speed and or velocity of matter with time
Speed?
Rate of movement in terms of distance measured in an allotted amount of time
Velocity?
Quickness or speed of an object in a given time and direction
Newtons 1st law
Inertia- an object at rest will remain at rest, or an object in motion will remain in motion at the same speed and in the same direction until acted upon by an outside source.
Newtons 2nd law
Force- an object moving with uniform speed is acted upon by an external force, the change of motion, or acceleration, will be directly proportional to the amount of force and inversely proportional to the mass of the object being moved.
Newtons 3rd law?
Actin and reaction- for every action there is an equal and opposite reaction
Bernoullis principle?
When a fluid flowing through a tube reaches a constriction or narrowing if the tube, the speed of the fluid passing through the constriction is increased and it’s pressure decreased.
Lift?
The force that acts, in an upward direction, to support the aircraft in air.
Weight?
The force of gravity acting downward on the aircraft and everything on the aircraft
Drag
The force that tends to hold an aircraft back.
Thrust?
The force developed by the aircrafts engine
Basic components of the aircraft?
Ailerons, elevators, rudder
What do ailerons control?
Roll-longitudinal axis
What do the elevators control?
Pitch-lateral axis
What does the rudder control?
Yaw-vertical axis
What type of aircraft has a cyclic stick?
Rotary wing aircraft
What does the cyclic stick control?
Roll/pitch
What type of aircraft has a collective?
Helicopter
What is a flap?
Leading/trailing edge- creates extra lift by lengthening the top section of the wing
What is a spoiler used for?
Used to decrease or spoil wing life by destroying the smooth flow of air over the wing surface.
What are speed breaks?
Hinged or moveable control surfaces used for reducing the speed of an aircraft
What are slats?
Movable control surfaces attached to the leading edge of the wing.
Explain angle of attack?
The angle at which the airfoil or fuselage meets a flow of air
Explain the purpose of auto rotation?
Method of allowing a helicopter to land safely from altitude without using engine power.
