correct answers
fixed-wing aircraft structure Correct Answer-1. Fuselage
2. Wings
3. Tail assembly or empennage
4. Landing gear
5. Powerplant
6. Flight instruments/controls and control surfaces
fuselage Correct 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 Correct Answer-from which the pilots and the flight crew control the
aircraft's operations
Two design types of fuselage construction Correct Answer-1. truss
2. monocoque
Truss construction fuselages Correct Answer-use steel or aluminum tubing in a
series of triangular shapes (called trusses) to get the necessary strength and rigidity
monocoque designs Correct 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 Correct Answer-airfoils attached to each side of the fuselage that serve as
the main lifting surfaces supporting the airplane in flight.
airfoil Correct 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 Correct Answer-airplanes with one set of wings
biplanes Correct Answer-airplanes with two sets of wings
cantilever wing Correct 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 Correct Answer-requires both internal bracing and external
support from struts attached to the fuselage
ailerons Correct 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 Correct 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 Correct 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
