The Fuselage and Empennage 4 2 . 1

The Aeroplane An “aeroplane” as defined by the Canadian Aviation Regulations (CARs) means a power-driven heavier-than-air aircraft that derives its lift in flight from aerodynamic reactions on surfaces that remain fixed during flight.

The Aeroplane Isn’t it an airplane??? Airplane is an American term. However, for the purposes of this course the terms airplane and aeroplane are interchangeable. Just remember for exam purposes that Canada uses the term “AEROPLANE”

Airplanes may be classified according to: Position and number of wings in relation to the fuselage, The number of engines, and The undercarriage configuration.

The essential components of an aircraft are: Fuselage, Wings or lifting surfaces, Tail section or empennage, Propulsion system, and Landing gear or undercarriage

The Fuselage The part that makes up the central body of the airplane, designed to accommodate the crew, passengers and cargo. Almost all other parts of the aircraft are attached to the fuselage.

Classification of Fuselage Truss Type Consist of tubes (wood or metal) that are usually welded or bolted together. The longerons are the principle member of the truss that run lengthwise. They are braced, or held together, by vertical or diagonal members to form the frame.

Classification of Fuselage STRINGER FORMER Classification of Fuselage Monocoque A series of rounded formers / bulkheads held together by stringers. The formers and bulkheads carry most of the load of the structure. The Stressed Skin that covers the fuselage is capable of carrying some of the load.

Empennage Attached on the rear of the fuselage is the tail group called the empennage. Horizontal Stabilizer a fixed, non-movable horizontal section of the tail plane. Elevator a moveable section of the tail group, hinged to the trailing edge of the horizontal stabilizer. Vertical Stabilizer (Fin) a fixed vertical section of the tail group placed in the center of the horizontal stabilizer and elevator. Rudder a moveable vertical section of the tail group hinged to the rear of the fin.

Empennage Canard Canard Stabilator Stabilator some modern aircraft have replaced part of the tail section with a canard - a horizontal stabilizer assembly is located at the front of the airplane. Stabilator Stabilator a single airfoil section that replaces the combination of stabilizer and elevator. It is attached to the fuselage at a point around which it pivots. Canard description on this page did not reflect that it was “part of the tail”.

The Fuselage and Empennage Theory of Flight The Fuselage and Empennage Congratulations!! You have now completed the Fuselage and Empennage lesson of the Theory of Flight Module. Of course, this lesson is always available to you for future reference if required. You are now ready to move along to the next Theory of Flight lesson you have not completed or to any other module you wish. You can advance to the Self Test Module if you feel ready to challenge the final exam. Good Luck! Text corrected – two “the”
