|
1. Fuselage 2. Wings 3. Tail assembly or empennage 4. Landing gear 5. Powerplant 6. Flight instruments/controls and control surfaces
|
Fuselage
|
Body of the airplane. Contains the cockpit, the cabin, cargo area (if there is one) attachment points for other major air plane components such as wings, tail section, and landing gear.
|
Firewall
|
A fireproof partition between the engine compartment and the cockpit/cabin to protect the crew and passengers (if any) from a fire in the engine.
|
Truss
|
Fuselage construction- truss construction fuselages use steel or aluminum tubing in a series of triangular shapes to get the necessary strength and rigidity.
|
Monocoque
|
Fuselage construction- designs use bulkheads, stringers (running the length of the fuselage) and formers (perpendicular to the stringers) of various sizes and shapes to support a stretched or "stressed" skin,
|
Airfoil
|
An aircraft part or surface (such as wings, propeller blades or rudder) that controls lift, direction, stability, thrust, or propulsion for the aircraft
|
High wing, mid-wing, low-wing
|
Wings may be attached at the top, middle, or bottom
|
Monoplanes
|
Airplanes with one set of wings
|
Biplanes
|
Airplanes with two sets of wings, usually stacked vertically
|
Cantilever
|
(in terms of wing bracing and support) cantilever wings require no external bracing, getting its support from internal wing spars, ribs, stringers and construction of the wing's skin or covering.
|
Semi-Cantilver
|
(in terms of wing bracing and support) requires both internal bracing and external support from struts attached to the fuselage
|
Ailerons and flaps
|
Control surfaces, both are attached to to the rear (trailing) edges of the wings.
|
Ailerons
|
Extend from about the middle of the wing out toward the wingtop; they move in opposite directions to create aerodynamic forces that cause the airplane to roll.
|
Flaps
|
Extend outward from near where the wing joins the fuselage (called the wing root) to about the middle of the wing's trailing edge.
|
Flaps are usually flush with the rest of the wing surface during cruising (constant speed, neither climbing nor diving) flight.
|
When flaps are extended, the flaps move downward together to increase the lift of the wing for takeoffs and landings.
