Block XIV Flashcards
act, or process, of changing place or position
motion
rate of change of the speed and/or velocity of matter with time
Acceleration
rate of movement in terms of distance measured in an allotted amount of time
Speed
quickness or speed of an object in a given time and direction
Velocity
something that causes a change in the motion of an object
Force
the willingness of an object to remain at rest or to continue is motion unless acted upon by an outside force
Inertia
when all of a body moves in a line with all parts moving in the same direction
Linear Motion
when a body or part of it moves in a circle about a point
Angular Motion
combo of linear and angular motion
General Motion
An object at rest will remain at rest, or an object in motion will continue in motion at the same speed and in the same direction, until acted upon by an outside force.
Newton’s First Law
If an object moving with uniform speed is acted upon by external force, the change of motion will be directly proportional to the amount of force and mass of the object being moved
Newton’s Second Law
For every action there is an equal and opposite reaction
Newton’s Third Law
This principle states that when a fluid flowing through a tube reaches a constriction or narrowing of the tube, the speed of the fluid passing thru is increased and its pressure decreased.
Bernoulli’s Principle
the force that acts, in an upward direction, support the aircraft in the air
Lift
force of gravity acting downward on the aircraft and everything on the aircraft
Weight
force that tends to hold an aircraft back; caused by the disruption of the air about the wings, fuselage, or body.
Drag
force developed by the aircraft’s engine, and acts in the forward direction
Thrust
On longitudinal axis
Ailerons (roll)
On lateral axis
Elevators (pitch)
On vertical axis
Rudder (yaw)
tilts the angle of rotor blades forward, aft, or sideways, giving helicopter its directional motion
Cyclic stick (roll/pitch)
counteracts torque of the main rotor by increasing or decreasing the amount of horizontal thrust
Tail rotor (yaw)
creates extra lift by lengthening the top section of the wing resulting in max lift to reduce takeoff runs and landing rollout
Flap
used to decrease or spoil wing lift by destroying the smooth flow of air over the wing surfaces
Spoiler
hinged or moveable control surfaces used for reducing the speed of aircraft
Speed brakes
movable control surfaces attached to the flaps; when open, a slot is created.
Slats
the angle at which the airfoil or fuselage meets a flow of air.
Angle of Attack
method of allowing a helicopter to land safely from altitude without using engine power.
Autorotation
(5) Landing Gear Components
- Shock Strut Assembly
- Tires
- Wheel Brake Assembly
- Retracting and Extending Mechanism
- Side Struts and Supports
Navy’s primary jet fuel
JP5-NATO Code F-44
displays the speed of aircraft in relation to the air in which it’s flying
Airspeed indicator
shows the height of the aircraft above sea level
altimeter
show the rate at which an aircraft is climbing or descending
rate-of-climb indicator
pilot determines this by referring to the horizon
attitude indicator
shows the correct execution of a turn and bank
turn and bank indicator
an electronic system that allows a friendly craft to identify itself automatically before approaching near enough to threaten the security of other naval units
Identification Friend or Foe (IFF)
used to detect objects at distances much greater than is visually possible
Radio Detection and Ranging (RADAR)
One radar range mile is how many microseconds?
12.36 microseconds
