Flight instruments/controls and control surfaces fuselage - 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 - from which the pilots and the flight crew control the aircraft's operations Two design types of fuselage construction - 1. truss 2. monocoque Truss construction fuselages - use steel or aluminum tubing in a series of triangular shapes (called trusses) to get the necessary strength and rigidity monocoque designs - 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 - airfoils attached to each side of the fuselage that s erve as the main lifting surfaces supporting the airplane in flight. airfoil - an aircraft part or surface (such as wing, propeller blade, or rudder) that controls lift, direction, stability, thrust, or propulsion for the aircraft. monoplanes - airplanes with one set of wings biplanes - airplanes with two sets of wings cantilever wing - 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 - requires both internal bracing and external support from struts attached to the fuselage ailerons - 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 - 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 - 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 - if we plot the points that lie halfway between the upper and lower surfaces, we obtain a curve called the mean camber line. camber - the maximum difference between the the mean camber line and the chord lin e. A measure of the curvature of the airfoil. thickness - the maximum difference between the upper and lower surfaces wingtips - the ends of the wings wingspan - the distance from one wingtip to the other a planform - the shape of the wing viewed from above dihedral angle - when 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; aThe benefits of buying summaries with Stuvia:
