Science test
what does the pilot do when he wants to pitch up
raise the elevatord
what does the pilot do when he wants to pitch down
lower the elevators
roll ocours when the wings
dip down
during roll the airplane rotates around its
longitudinal axis
where are the ailerons located
at trailing edge of the wings
what does the plane do when it wants to roll right
the left aileron goes up and the right aileron goes down
what does yaw have to do with
yaw has to do with turning the airplanes nose right or left
to yaw right you must
turn the rudder right
what must happen to yaw left
turn the rudder left
where is the rudder located
at the trailing edge of the vertical stabilizers
what does the pilot must do to turn the airplane
he or she must do a combination of yawing and rolling
to bank right what do you do
yaw right roll right
what needs to happen when you bank left
yaw left roll left
what do serveral diffrent aircrafts have in common
they are based on the principle that when possible air pressure tries to equilaze. And they are based on the principle that if is a force that is directed in one direction there will be an equal force directed in the opposite direction
whta are two difrrent ways that aircrafts produce thrust
jet engines propellers and rocket launchers
the principles on how a car move are the same as as a jet engine that provideds thrust to a jet engine true or false
true
what is the first step on how a jet engine works
air is taken in = the engine sucks in air in the front with a fan
what is the secound step on how a jet engine works
the air is compressed = a set of blades attached to a shaft rotates. this compresses the air thus raising the pressure of the air
whats the third step in how a jet engine works
the compressed air is fueld with gas and ignited = the compressed air is then is sprayed with fuel and an electric spark lights the mixture
whats the fourth step on how a jet engine works
the gas mixture expands quickly as it expands = as the gas mixture burns it expands very expands furthur. this raises the pressure in the combustion chamber even more
whats the 5 step on how a rocket launch
the gases gush through the jet nozzle toward the ground with a tremendous amount of force
what is the 6 step on how a rocket launches
the rocket lifts off the launch pad in the oposite direction as the escaping gases. the force of the escaping gases are enough to launch the rocket
what do liqued rockets use as fuel
liqued oxidizer and liquid fuel
what do solid fuel rockets burn
they burn this fuel and oxidizer
whats the 1 step on how a rocket is launched
fuel is mixed with oxegen
whats the 2 step on how a rocket is launched
the fuel oxegen is ignited in a combustion chamber. this produces large amounts of heat and gases
whats the 3 step on how a rocket is launched
the hot gases become compressed as they fill the combustion chamber. The pressure inside the combustion chamber is very high compared to the surrounding air pressure
whats the 4 step on how a rocket is launched
the compressed gases are allowed to escape through a jet nozzle .
what is the 5 step on how a jet engine works
the gases escape through nozzles = the air that is being pressured tries to equalize with the air around the engine. they are able to escape through tiny holes called nozzles
what is the 6 step on how a jet engine works
the escaping vapours provide thrust = the gases exit the engine with great force which provides thrust moving the rocket forward
