Fundamentals Of Flight Flashcards
What is motion?
Act or process of changing place or position
Define acceleration
Change of speed over time
Define speed
Distance measured over time
Describe velocity
Quickness or speed of an object in given time or direction or
Describe force pertaining to motion
Something that causes a change in motion
Describe inertia pertaining to motion
Willingness of an object to remain at rest
Describe acceleration pertaining to motion
Rate of change of the speed and or velocity of matter with time
What is newton’s first law?
(inertia) An object 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.
What is newton’s second law?
(Force) if 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
What is newton’s third law?
(Action and reaction) for every action there is an equal and opposite reaction
Explain Bernoulli’s principle
When a fluid flowing through a tube reaches a constriction or narrowing of the tube, the speed of the fluid passing through the constriction is increased and it’s pressure decreased.
Define lift
The force that acts, in an upward direction, to support the aircraft in the air
Define weight
The force of gravity acting downward on the aircraft
Define drag
The force that tends to hold the aircraft back
Thrust
The force developed by an aircraft’s engine, it acts in the forward direction
List the axis of the aircraft
1) Longitudinal axis- imaginary reference line running down the center of the aircraft (nose and tail)
2) lateral axis- imaginary reference line running parallel to the wings
3) vertical axis- imaginary reference line running from the top to the bottom of the aircraft
Ailerons control what axis?
Longitudinal axis (roll)
Elevators control what axis?
Lateral (pitch)
Rudders control what axis?
Vertical axis (yaw)
What does the cyclic stick do?
Tilts the plane forward,aft or sideways, giving the helicopter its directional motion by changing the direction of the lift
