Theory of flight Flashcards
Formula of lift
L=CL1/2PV(squared)S
Density formula
D=m/v
Lift
an upward force
Weight
gravity downward
Thrust
Forward force
Drag
rearward force
Atom
Smallest particle of an element
Monoque
external skin
Semi-Monoque
longerons, ribs and frames
Newton’s First Law
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton’s Third Law
Every action has an equal and opposite reaction
Newton’s Second Law
Force equals mass times acceleration
Flaps
Increase lift and drag
Aileron
flight controls that is used in longitudinal axis
Expand
if the liquid is heated it
Wing spar
main structural member of the wing
Aerofoil
a device that gets reaction from air moving over its surface
Angle of Attack
The angle formed by the wing chord line and the relative wind.
Angle of Incidence
angle formed by the chordline and the longitudinal axis of the microlight
Aspect ratio
ratio between the span and chord (s/c)=AR
Axis of rotation
An imaginary line around which rotation occurs
Roll-longitudinal
Axis
Yaw-vertical
Axis
Pitch-Lateral
Axis
