Fundamentals of flight

Question 1

What is motion?

Answer 1

The act or process of changing place or position

Question 2

What are three types of motion?

Answer 2

• linear(moves in a line or same direction)
• angular(moves in a circle)
• general(combo of both)

Question 3

define force

Answer 3

something that causes change in the motion of an object

Question 4

Define inertia

Answer 4

Willingness of an object to remain at rest or to continue in motion unless acted upon by an outside force

Question 5

Define acceleration

Answer 5

Rate of change of the speed and velocity of matter w/ time

Question 6

Define Velocity

Answer 6

Quickness of speed of an object in a given time and direction

Question 7

Define speed

Answer 7

Rate of movement in terms of distance measured in an allotted amount of time

Question 8

Newtons first law?

Answer 8

An object at rest will remain at rest an object in motion will continue in motion

Question 9

newtons second law?

Answer 9

an object moving with uniform soeed is acted upon by an external force,then change of motion.will be directly proportional to the amount of force &inversely proportional to the mass of the object moved

Question 10

newtons 3rd law?

Answer 10

for every actin there is an equal and opposite reaction

Question 11

bernoullis principle?

Answer 11

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 & pressure is decreased

Question 12

Define lift

Answer 12

Force that acts in an upward direction to support the aircraft in the air

Question 13

Define weight

Answer 13

Force of gravity acting downward on the aircraft & everything on the aircraft

Question 14

Define drag

Answer 14

Force that tends to hold an aircraft back

Question 15

Define Thrust

Answer 15

The force developed by the aircrafts engine & it acts in the forward direction

Question 16

Longitude

Answer 16

the imaginary line running down the center of aircraft

Question 17

Latitude

Answer 17

imaginary line running parallel to wings

Question 18

vertical

Answer 18

Imaginary line running top to bottom of aircraft

Question 19

ailerons control what axis?

Answer 19

longitudinal

Question 20

Elevators control what axis?

Answer 20

lateral

Question 21

Rudder controls what axis?

Answer 21

Vertical

Question 22

What does the cyclic stick do?

Answer 22

Tilts plane forward,aft or sideways

Question 23

what does the tail rotor do?

Answer 23

Counteracts the torque of main rotor by increasing/decreasing the amount of horizontal thrust the tail rotor produces

Question 24

Define flap

Answer 24

Creates extra lift by lengthening the top section of the wing resulting in max. lift to reduce takeoff runs & landing rollout

Question 25

define spoiler

Answer 25

used to decrease or spoil wing lift by destroying the smooth flow of air over the wing surfaces

Question 26

define speed brakes

Answer 26

Hinged of moveable control surfaces used for reducing the speed of an aircraft

Question 27

Define slats

Answer 27

Moveable control surfaces attached to the leading edge of the wing

Question 28

Define an airfoil

Answer 28

Air that creates lift

Question 29

Whats the difference between a fixed wing airfoil and a helo airfoil?

Answer 29

A fixed wing pulls air through the engine creating thrust to lift the plane. Helo pushes air down through the rotors to lift up

Question 30

Define collective

Answer 30

Lift may be changed by collectively increasing the angle of attack or pitch of the rotor blades

Question 31

Define AOA

Answer 31

The angle at which the airfoil or fuselage meets a flow of air

Question 32

Define autorotation

Answer 32

Method of allowing a helicopter to land safely from altitude w/o using engine power

Question 33

Explain the basic aircraft hydraulic system

Answer 33

• A reservoir to hold a supply of hyd fluid
• A pump to provide a flow of fluid
• Tubing to transmit the fluid
• A selector valve to direct the flow of fluid
• An actuating unit to convert the fluid pressure into useful work

Question 34

What are the components of landing gear?

Answer 34

• Shock strut assembly
• tires
• wheel brake assembly
• retracting and extending mechanism
• side struts and supports

Question 35

What is autorotation?

Answer 35

Method of allowing a helicopter to land safely from altitude w/o using engine power
