What are the 4 forces that act on a plane in flight?
Thrust, Drag, Lift, Weight
Airfoil
Name for wing design
Center of Gravity (COG)
Point where plane balan
Steady unaccelerated flight
Thrust = Drag, Weight = Lift
2 Types of drag
Parasite & Induced
3 types of parasite drag
Form, skin friction, interference
LD Max
Lift:Drag ratio
How induced drag changes as airspeed increases
decreases exponentially
How parasite drag changes as airspeed increases
increases exponentially
Bernoulli’s Principle
faster speeds mean less pressure
3 components of Relative Wind
wind from thrust, prop wash, natural wind
Newton’s 3rd law
every action has equal & opposite reaction
Ways to create more lift
more speed, more camber (lower flaps), increase AOA
Stall
Rapid loss of lift
name for line between leading and trailing edge of air foil
chord line
Angle of Attack (AOA)
Angle between relative wind and chord line
How does steeper AOA affect lift
More lift
laminar air flow
individual planes of air going over wings
Boundary layer seperation
occurs when there is a steep AOA, causes turbulence, air doesn’t glide over wings smoothly anymore
Critical Angle of Attack
Exceeding this will always cause a stall
Lower AOA
Main way to break a stall
Spin
Aggravated stall (stall when uncoordinated), one wing stalls more than the other
What is the acronym PARE for?
Getting out of a spin
PARE
Power - Idle
PARE
Ailerons & Elevator neutral
PARE
Rudder - opposite (until spinning stops)
PARE
Elevator - up (to resume level flight)
How many wings are stalled in a spin?
Both, but one more than the other
Lateral Axis
Pitch Axis
Longitudinal axis
roll axis
Vertical Axis
Yaw axis
How to control lateral axis?
Elevator
How to control longitudinal axis?
Ailerons
How to control verical axis?
Rudder
Stability
the ability to correct for disturbances and return to flight path
static stability
initial tendency of the airplane after a disruptiond
dynamic stability
reaction over time after a disturbance to flight path
What is the positive static stability result after a ↗ disturbance?
↘
What is the neutral static stability result after a ↗ disturbance?
↗
What is the negative static stability result after a ↗ disturbance?
⬆
Dynamic stability types
Controllability
The measure of how well an airplane responds to inputs
As stability decreases, what happens to controllability?
It decreases as well
COG too far back
Makes recovering from stall (lowering AOA) more difficult
Slip stream
air flow over form of airport
Flaps
Increase lift & drag
Main benefit of flaps
Allows landing at slower airspeeds and allows for an increased descent angle
Plain flaps
simplest type of flap
Split flap
flaps that deflect from lower surface of wings
slotted flap
most common flaps (allows for extra lift without too much drag)
(slotted) fowler flap
flaps that extend on rails or tracks
