Chapter 1 Flashcards
Fuselage
Body, cockpit
Wing
generates force called Lift, ans attached to Fuselage
Monoplane
One set of Wings
Biplanes
Two sets of wings
Empennage
tail section, consists of vertical and horizontal stabilization, rudder and elevator
Rudder
attached on vertical stabilizer, controls pedals in cockpit control left and right
Elevator
attached on horizontal stabilizer, control wheel in cockpit control up and down movements
Fixed Landing Gear
landing gear that is fixed in a downward
position, cannot be retracted
Retractable Landing Gear
Landing Gear that is retractable
Shock Struts
Absorb jolts and movements, located in wheels of landing gear
Powerplant
propeller + Engine
Cowling
Covers Engine, propeller attached to front of cowling
Firewall
protects cockpit from engine
Certification Normal+Utility
usually small planes
Certification Acrobatic
fewer operating limitations, designed for more power
Certification Commuter
passenger limit 19, 19,000 lbs limit
Certification Transport
surpasses passenger and weight limits
Certification Restricted
crop dusting and fighting fires
Certification Limited
Military
Certification Provisional
new designs, doesn’t meet all regulations, made for particular purposes
Certification Experimental
homebuilt, racing, testing out new concepts
four forces of flight
lift, weight, thrust, drag
Lift
Must overcome Drag, airflow over wing
Weight
Weight of aircraft, pressure + gravity affect weight
Thrust
must overcome drag, propels airplane through the air
Drag
pushes airplane back, opposes speed and thrust
what happens when the lift and weight are the same?
cancel each other out, making it zero
What is Bernoullis Principle?
as the velocity of fluid increases, pressure decreases
What happens when air flows over the curve of a wing?
the velocity increases and pressure decreases, this produces the upward force of lift
