newton Laws
1:object stays at rest or krrp moving unless a force acts on it
2:force=mass x acceleration
3:for every action there is an equal and opposite reaction
what are the 4 criterias that will affect lift
1:the surface =wing aspect ratio
2:the camber=wing camber and profile
3:the angle of attack= relative the the airflow
4:the speed=speed of aircraft
what is the load factor in a turn
-ratio between real weight and dinamic weight
45 turns=1,15G
60 turns=2G
cause when there is ice on wings
-reduce the wing lift by 30%
-increase drag by 40%
drag and air speed
+Airspeed = Less induced drag
+Airspeed = More parasite drag
the strains (due to stress)
tension: stretching - bracing wires
torsion= twisting - gears fuselage
flexion= bending - fuselage wings and landing gears
fix tab
small metal plate
adjusted by manufacturer or mecanic
to correct tendency of airplane to pull or drift in one direction
3 axis
longitudinal=(roll) ailrons
lateral= (pitch) elevator
vertiacal= (Yaw) rudder
three types of wings
sweepback= make aircraft laterally stable
helps plane to be level
efficent at high speed
elliptical= (round) idial at high and low speed due to minimum drag for given apect ratio
rectangular= provide a decrease from drag and increase lift
good stall characterisics
five mains airplane parts
1-fuselage
2-emprennage
3-wing
4-wheels
5-engine

forces in flight
up=vertical component
down=weight
right=centrifugal
left=centripedal
resultant loead
