Monocoque Structure - ANSWER 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 the total weight
of the aircraft.
Semi-Cantilever Wing - ANSWER requires both internal bracing and
external support from struts attached to the fuselage
Biplane - ANSWER an airplane with two pairs of wings
Thickness - ANSWER a percentage of the wing chord; typically ranges
from 6.5 to 13.5 percent
Camber Line - ANSWER amount of curvature of the wing. Imaginary line
runs halfway between upper and lower surfaces of the wing.
Chord - ANSWER the imaginary line in an airfoil; establishes a baseline
for the amount of camber and width required of the wing along with its
wingspan
How many types of wing platforms are there? - ANSWER 4 (rectangular,
elliptical, tapered, and swept)
Rectangular wing planform - ANSWER the simplest type, highly
inefficient, and typically used for light general aviation
Elliptical wing planform - ANSWER the most efficient style, with the lowest
possible induced drag
Tapered wing planform - ANSWER cross between a rectangular and an
elliptical, providing better lift distribution and moderate efficiency. Aircraft
with these wings have a wide range of speeds
, Swept wing planform - ANSWER tapered back to reduce drag. Includes
slightly swept, moderately swept, and sharply swept types. Disadvantages:
tendency to twist under stress
The amount of lift generated is dependent on the difference between the
camber line and the _________ - ANSWER chord line (when the
measurements of the chord line and camber line differ greatly, the
curvature of the wing will provide more lift)
powerplant - ANSWER encompasses the engines and propellers as well
as the induction, exhaust, electrical, cooling, lubrication, and fuel systems
reciprocating engine - ANSWER An engine that converts heat energy
created by combusted fuel mixed with air into reciprocating piston
movement, which in turn is converted into a rotary motion via a crankshaft.
(typically aircraft with cruising speed not exceeding 250 mph)
gas turbine engine - ANSWER Engine that burns natural gas, sending a
hot, high-pressure stream of gas through a turbine connected to an
electrical generator. (larger more powerful planes)
turbo-supercharged reciprocating engine - ANSWER aircraft traveling at
high altitudes (over 30,000 ft)
Turbojet engine - ANSWER A turbine engine which produces its thrust
entirely by accelerating the air through the engine. (those that operate at
Mach 1 or higher)
during takeoff, engines operate at ________ - ANSWER maximum
performance
fixed pitch propeller - ANSWER pitch has a blade angle that can't be
changed by the pilot. The propeller is connected directly to the engine's
crankshaft; engine power rotates the crankshaft as well as the propeller,
and the propeller converts the engine's rotary power into thrust
Variable pitch propeller - ANSWER Allows the pilot to adjust the blade
, pitch during flight
pusher propeller - ANSWER installed on the rear of an aircraft and faces
to the rear; the thrust created from its rotation pushes on the rear of an
aircraft instead of pulls the aircraft, contrary to fixed and variable
The pitch of any styles of propeller affects _______ - ANSWER the way it
cuts through the air, producing air mass
Thrust Horsepower Equation - ANSWER thp=(thrust x aircraft speed (in
mph))/375 pph
Styles of landing gear - ANSWER tail wheel, tandem, tricycle
tail wheel - ANSWER landing gear consisting of a third wheel assembly,
beneficial for landing on non-paved runways (when aircraft's main landing
gear is positioned forward of its center of gravity)
tandem landing gear - ANSWER has both main and tail portions mounted
along the longitudinal axis of the aircraft. Supports the use of flexible wings
tricycle landing gear - ANSWER includes a main gear and a nose gear,
which together support increased braking ability, higher landing speeds,
and better visibility for ground operations
tail (empennage) - ANSWER rear portion of the aircraft; provides stability
and consists of the rudder, vertical stabilizer, horizontal stabilizer, the trim
tabs, and 2 elevators
vertical tail structure consists of _____ - ANSWER rudder and vertical
stabilizer
rudder - ANSWER used to keep the aircraft in coordinated flight; at the
rear end of the vertical stabilizer
Vertical Stabilizer - ANSWER To control yaw.
