fixed-wing aircraft structure - Answer 1. Fuselage
2. Wings
3. Tail assembly or empennage
4. Landing gear
5. Powerplant
6. Flight instruments/controls and control surfaces
fuselage - Answer body of an airplane. Contains the cockpit, the cabin, the cargo area if there
is one, and attachment points for other major airplane components, such as wings, tail section,
and landing gear.
cockpit - Answer from which the pilots and the flight crew control the aircraft's operations
Two design types of fuselage construction - Answer 1. truss
2. monocoque
Truss construction fuselages - Answer use steel or aluminum tubing in a series of triangular
shapes (called trusses) to get the necessary strength and rigidity
monocoque designs - Answer use bulkheads, stringers, (running the length of the fuselage)
and formers (perpendicular to stringers) of various sizes and shapes to support a stretched or
"stressed" skin
wings - Answer airfoils attached to each side of the fuselage that serve as the main lifting
surfaces supporting the airplane in flight.
airfoil - Answer an aircraft part or surface (such as wing, propeller blade, or rudder) that
controls lift, direction, stability, thrust, or propulsion for the aircraft.
monoplanes - Answer airplanes with one set of wings
biplanes - Answer airplanes with two sets of wings
, cantilever wing - Answer requires no external bracing, getting its support from internal wing
spars, ribs, and stringers, as well as the construction of the wing's skin or covering
semi-cantilever wing - Answer requires both internal bracing and external support from struts
attached to the fuselage
ailerons - Answer extend from about the middle of the wing out toward the wingtip; they
move in opposite directions to create aerodynamic forces that cause the airplane to roll
flaps - Answer extend outward from near where the wing joins the fuselage (called the wing
root) to about the middle of the wing's trailing edge. The flaps are usually flush with the rest of
the wing surface when cruising flight; when they are extended, the flaps move downward
together to increase the lift of the wing for takeoffs and landings. Most common high lift
devices.
chord line - Answer the distance from the leading edge of the wing to the trailing edge. Cuts
the airfoil into an upper surface and a lower surface
mean camber line - Answer if we plot the points that lie halfway between the upper and lower
surfaces, we obtain a curve called the mean camber line.
camber - Answer the maximum difference between the the mean camber line and the chord
line. A measure of the curvature of the airfoil.
thickness - Answer the maximum difference between the upper and lower surfaces
wingtips - Answer the ends of the wings
wingspan - Answer the distance from one wingtip to the other
a planform - Answer the shape of the wing viewed from above
dihedral angle - Answer when the left and right wings aren't truly horizontal to the fuselage,
but instead meet at this angle. Built into the design for roll stability; a wing with some dihedral
will naturally return to its original position if it encounters a slight displacement
Three basic wing types on modern airplanes - Answer 1. straight
2. Sweep
3. Delta
