Science
What does pitch have to do with?
whether the airplane's nose is horizontal, pointing up, or pointing down
What does a pilot do when changing the airplane's pitch?
rotate the airplane around the lateral axis
If a pilot wants to pitch up what must he do?
raise the elevators
if a pilot wants to pitch down what must he do?
lower the elevators
what does the pilot use to control pitch?
the pilot uses the elevators
when does roll occur?
when the airplane's wings dip up and down
during roll what does the airplane rotate around?
rotates aroind the longitudinal axis
what happens when the left wing dips down?
the right wing moves up
what does the pilot use to control roll?
the pilot uses the ailerons to control roll
where are the ailerons located?
the trailing edge of the wings
what does the pilot have to do when he rolls right?
right aileron up and the left aileron down
what does the pilot have to do when he rolls left?
left aileron up and right aileron down
what does yaw have to do with?
turning the airplane's nose right or left
when would a pilot use yaw?
when they want to change the direction of flight
when changing yaw what does the airplane rotate on?
rotates on the vertical axis
what does the pilot do when they yaw right?
turn the rudder right
what does the pilot do when they want to yaw left?
turn the rudder left
what does the pilot use to control yaw?
the rudder
where is the rudder located
the trailing edge if the vertical stabilizer
what does a pilot do if they want to bank?
a combination of yawing and rolling
when would a pilot use banking?
when they want to turn an airplane
to bank right what would you do?
yaw right and roll right
to bank left what would you do?
yaw left and roll left
when lift is greater than weight the airplane will
ascend
when weight is greater than lift the airplane will
descend
when thrust is greater than drag the airplane will
accelerate
when drag is greater than drag the airplane will
decelerate
when lift and weight are equal and thrust and drag are equal the airplane will
hover
what are the three axes?
lateral, longitudinal and vertical axis
what are the controlling surfaces of an airplane?
ailerons, elevator and rudder
what is the fuselage?
the aircraft main body that holds the pilot, passengers and cargo
what are the horizontal stabilizers?
a set of miniature wings located on the aircraft's body
what are the verical stabilizers?
upright fin located on the tail of the airplane
what is a propeller?
a device consisting of a set of blades mounted to a shaft that is spun
what is the purpose of a propeller?
to create thrust
how does a propeller create thrust?
accelerating a large amount of mass ti a higher speed
what are 3 more efficient ways for a propeller to produce thrust
shaped like and airfoil
slightly twisted
taper off at the ends
what is a jet engine?
an object that provides thrust for airplanes
what are the 3 different principles of a jet engine?
compressed air had higher pressure than non compressed air
air pressure tries to equalize
there will be an equal force in the opposite direction
how does a jet engine work?
air is taken in
air can be compressed
compressed air is mixed with fuel and ignighted
gas mixture expands very quickly as it burns
the gasses escape through nozzels
the escaping vapours provide thrust
what are the principles rocket science is based off
fuel burns and form heat and gasses
gases take up more room than liquids
gas is compressed, compresses gases have higher pressure than non compressed gases
areas of gases will try to equalize
if force is produced in one direction another force is produced in the oppostie direction
