AFOQT Aviation Information accurate fixed-wing aircraft structure - ANSWERS1. Fuselage 2. Wings 3. Tail assembly or empennage 4. Landing gear 5. Powerplant 6. Flight instruments/controls and control surfaces fuselage - ANSWERSbody 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 - ANSWERSfrom which the pilots and the flight crew control the aircraft's operations Two design types of fuselage construction - ANSWERS1. truss 2. monocoque Truss construction fuselages - ANSWERSuse steel or aluminum tubing in a series of triangular shapes (called trusses) to get the necessary strength and rigidity monocoque designs - ANSWERSuse 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 - ANSWERSairfoils attached to each side of the fuselage that serve as the main lifting surfaces supporting the airplane in flight. airfoil - ANSWERSan aircraft part or surface (such as wing, propeller blade, or rudder) that controls lift, direction, stability, thrust, or propulsion for the aircraft. monoplanes - ANSWERSairplanes with one set of wings biplanes - ANSWERSairplanes with two sets of wings cantilever wing - ANSWERSrequires 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 - ANSWERSrequires both internal bracing and external support from struts attached to the fuselage ailerons - ANSWERSextend 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 - ANSWERSextend 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 - ANSWERSthe 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 - ANSWERSif we plot the points that lie halfway between the upper and lower surfaces, we obtain a curve called the mean camber line. camber - ANSWERSthe maximum difference between the the mean camber line and the chord line. A measure of the curvature of the airfoil. thickness - ANSWERSthe maximum difference between the upper and lower surfaces wingtips - ANSWERSthe ends of the wings wingspan - ANSWERSthe distance from one wingtip to the other a planform - ANSWERSthe shape of the wing viewed from above dihedral angle - ANSWERSwhen 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 - ANSWERS1. straight 2.
