 AILERONS AND SPOILERS The ailerons are the primary flight control surfaces used to provide lateral (roll) control of the aircraft; that is; they control aircraft movement about the longitudinal axis. They are usually mounted on the trailing edge of the wing near the tip. They are rigged so that when one is moving upward on one wing, the other is moving downward on the opposite wing. This movement changes the camber of the respective wings, with the down-ward-moving aileron increasing the camber and lift, and the upward-moving aileron decreasing the camber and lift. Since the ailerons are located outboard of the roll axis, this change in camber will result in a rolling motion. Large turbine aircraft often employ two sets of ailerons, one set being approximately mid-wing or immediately outboard of the inboard flaps, and the other set being in the conventional location near the wingtips. The outboard ailerons become active whenever the flaps are extended beyond a fixed setting (at low sp

 AEROPLANE AERODYNAMICS AND FLIGHT CONTROLS An airplane is equipped with certain fixed and movable surfaces, or airfoils, which provide for stability and control during flight. Each of these airfoils is designed to perform a specific function in the flight of the airplane. FIXED AIRFOILS The fixed airfoils are the wings, the horizontal stabilizer, and the vertical stabilizer (fin). The function of the wings has been previously discussed. The tail section of the airplane, including the stabilizers, elevators, and rudder, is commonly called the empennage. MOVABLE CONTROL SURFACES Movable flight control surfaces are divided into two categories; 1. Primary flight controls 2. Secondary flight controls The primary control surfaces of an airplane include the ailerons, elevators, and rudder. The secondary control surfaces include flaps; trim tabs, spoilers, and slats. The principles of the operation of flaps and spoilers are discussed later in this module. The primary control surfaces are used

 EXHAUST SECTION The exhaust section of the gas turbine engine consists of several components. Although the components have individual purposes, they also have one common function: they must direct the flow of hot gases rearward in such a manner as to prevent turbulence and, at the same time, impart a high final or exit velocity to the gases. In performing the various functions, each of the components affects the flow of gases in different ways. The exhaust section is located directly behind the turbine section and ends when the gases are ejected at the rear in the form of a high-velocity exhaust gases. The components of the exhaust section include the exhaust cone, tailpipe (if required), and the exhaust nozzle. The exhaust cone collects the exhaust gases discharged from the turbine section and gradually converts them into a solid flow of gases.  The exhaust cone assembly consists of an outer shell or duct, an inner cone, three or four radial hollow struts or fins, and the necessary n
