PLTW Aerospace Questions with Correct Answers
Aerospace Engineer Correct Answer-Develops new technologies for use
in aviation, defense systems, and space exploration, often specializing in
areas such as structural design, guidance, navigation and control,
instrumentation and communication, and production methods.
Aircraft Correct Answer-A device that is used or intended to be used for
flight in the air.
ATC Correct Answer-Air Traffic Control, A system is to prevent a
collision between aircraft operating in the system and to organize and
expedite the flow of traffic, and to provide support for National Security
and Homeland Defense.
FAA Correct Answer-Federal Aviation Administration. The U.S.
Federal Aviation Administration is an operating mode of the Department
of Transportation responsible for the safety of civil aviation.
NASA Correct Answer-National Aeronautics and Space Administration.
The United States government agency that is responsible for science and
technology related to air and space.
NACA Correct Answer-National Advisory Committee for Aeronautics.
From March 3, 1915 until October 1, 1958, the National Advisory
Committee for Aeronautics (NACA) provided advice and carried out
much of the cutting-edge research in aeronautics in the United States.
,Aileron Correct Answer-Small-hinged sections on the outboard portion
of a wing that are used to generate a rolling motion for an aircraft.
Airfoil Correct Answer-Any surface, such as a wing, which provides
aerodynamic force when it interacts with a moving stream of air.
Angle of Attack Correct Answer-The angle formed by the wing chord
line and the relative wind.
Aspect Ratio Correct Answer-The relationship between the length and
width of a wing.
Boundary Layer Correct Answer-A thin layer of air next to the surface
of an airfoil which shows a reduction in speed due to the air's viscosity.
Center of Gravity Correct Answer-The common reference point for the
three axes of the aircraft.
Cockpit Correct Answer-The space in the fuselage of a small airplane
containing seats for the pilot, copilot, and sometimes passengers.
Controllability Correct Answer-The capability of an aircraft to respond
to your flight inputs, especially with regard to attitude and flight path.
Dihedral Correct Answer-The mounting of wings so that the wingtips
and higher than the wingroot.
, Drag Correct Answer-Acts in the opposite direction of flight, opposes
the forward-acting force of thrust, and limits the forward speed of the
aircraft.
Dynamic Stability Correct Answer-Out of its own accord, an aircraft
eventually returns to and remains at its equilibrium position over a
period of time.
Elevator Correct Answer-A rear horizontal stabilizer that controls up and
down or pitching motion of the aircraft nose.
Empennage Correct Answer-The tail assembly of an aircraft, including
the horizontal and vertical stabilizers, elevators and rudder.
Flaps Correct Answer-Control surfaces attached to the trailing edge of
the wing extending outward from the fuselage to the midpoint of each
wing. Flaps can increase the lifting efficiency of the wing and decrease
stall speed.
Fuselage Correct Answer-Houses the cabin, the cockpit and is a
common attachment point for the other major components.
Glider Correct Answer-An aircraft that is designed to fly without an
engine.
