Answers
Fixed-wing aircraft structure Ans: 1. Fuselage
2. Wings
3. Tail assembly or empennage
4. Landing gear
5. Powerplant
6. Flight instruments/controls and control surfaces
Fuselage Ans: 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 Ans: From which the pilots and the flight crew controls the
aircraft's operations
Two design systems of fuselage construction Ans: 1. Truss
2. Monocoque
, Page | 2
Truss construction fuselages Ans: Use steel or aluminum tubing in a
series of triangular shapes (called trusses) to get the necessary
strength and rigidity. Consists of welded steel-tubing longerons
separated by diagonal members to endure the loads placed
upon the aircraft.
Monocoque construction fuselages Ans: 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. Consists of a thin sheet-aluminum alloy curved to fit
the shell of the fuselage. This metal skin is designed to withstand
the stress of loads and minimize the total weight of the aircraft.
Wings Ans: Airfoils attached to each side of the fuselage that
serve as the main lifting surfaces supporting the airplane in flight
Airfoil Ans: An aircraft part or surface (such as wing, propeller
blade, or rudder) that controls lift, direction, stability, thrust, or
propulsion for the aircraft
Monoplanes Ans: Airplanes with one set of wings
Biplanes Ans: Airplanes with two sets of wings
Cantilever wing Ans: 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 Ans: Requires both internal bracing and
external support from struts attached to the fuselage
, Page | 3
Ailerons location Ans: 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 Ans: 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 Ans: 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 Ans: If we plot the points that lie halfway
between the upper and lower surfaces, we obtain a curve called
the mean camber line
Camber Ans: The maximum difference between the mean
camber line and the chord line. A measure of the curvature of the
airfoil
Thickness Ans: The maximum difference between the upper and
lower surfaces. A percentage of the wing chord; typically ranges
from 6.5 to 13.5 percent.
Wingtips Ans: The ends of the wings
Wingspan Ans: The distance from one wingtip to the other
A planform Ans: The shape of the wing viewed from above
