| Types of fixed wing aircraft? |
|
Definition
|
|
Term
|
Definition
| get their thrust by the corkscrew action of one or more propellers with two or more blades each rotating very fastin front of the enginge, which pushes air backward with the result that the plane is pushed forward |
|
|
Term
| What law is associated with propeller aircraft? |
|
Definition
|
|
Term
|
Definition
| pilot can not change the angle of the blade; connected directly to crankshaft; engine rotates the crankshaft and propeller, propeller converts engens power into thrust |
|
|
Term
| Variable-pitch propellor or constant speed propeller |
|
Definition
| blade angle can be adjusted by pilot |
|
|
Term
|
Definition
| forcing incoming air into a tube or cylinder where the air is compressed, mixed with fuel , burned and pussed exhausted at high speed to generate thrust |
|
|
Term
|

|
Term
|
Definition
|
|
Term
|
Definition
| used to turn airplane while flying |
|
|
Term
| Netwons first law or Motion (inertia) |
|
Definition
| a body at rest remains at rest; a body in motion tends to remain in motion unless acted upon by an outside force |
|
|
Term
| Newton's second law of Motion |
|
Definition
F=ma
F- forces acting on an object
m- object's mass
a- object's acceleration |
|
|
Term
| Newton's Third law of motion |
|
Definition
For every action there is an equal and opposite reaction.
when one object exerts a force on another object the second object exerts and equal and opposite force on the first object. |
|
|
Term
|
Definition
| two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. |
|
|
Term
| what are the four forces that act in flying? |
|
Definition
| lift, gravity (weight), drag & thrust |
|
|
Term
|
Definition
| pushes the aircraft up awa from the earth |
|
|
Term
|
Definition
| pulls the aircraft towards earth |
|
|
Term
|
Definition
| pushes the aircraft forward |
|
|
Term
|
Definition
| resistance to the aircraft going forward |
|
|
Term
| What principle is used to provide lift? |
|
Definition
|
|
Term
|
Definition
velocity of fluid increases, the pressure exerted by that fluid decreases;
the faster a fluid travels over a surface the less time it has to exert pressure on any given part of that surface |
|
|
Term
|
Definition
caused by separation of air flow from the wings upper surface; rapid decrease in lift; falling out of the sky
|
|
|
Term
| How does a pilot counteract stalling? |
|
Definition
| decreasing the angle of attack below the stalling angle |
|
|
Term
| Profile or Parasiitic drag |
|
Definition
| cause by the plane pshing air out of the way as it moves forward |
|
|
Term
|
Definition
| result of the production of lift;force produced by the wing that is parallel to the relative wind |
|
|
Term
|
Definition
| objects that creat lift must overcome induced drag |
|
|
Term
|
Definition
| combination of lift, gravity, thrust and drag and others that allow the aircraft to be flown |
|
|
Term
| flying outside the envelope |
|
Definition
| unsafe condition that causes problems in maintaining stability or the ability to fly |
|
|
Term
