To meet these requirements, the aircraft is highly powered and has a very strong structure. For example, when bending a piece of tubing, the upper portion stretches (tension) and the lower portion crushes together (compression). Aircraft Structures for engineering students Author: T.H.G. Most aircraft structure mechanics actually find jobs in the technology and professional industries. The Aircraft Structures (ACS) trade was brought about during a time of fiscal constraints for the Canadian Forces. Bending action is shown in. Stresses are analyzed and considered when an aircraft is designed. General The structures of most flight vehicles are thin walled structures (shells) Resists applied loads (Aerodynamic loads acting on the wing structure) Provides the aerodynamic shape Protects the contents from the environment SPATER Definitions Primary structure: … Structure Repair For the entire aircraft – incl. If you're interested in becoming an aircraft structure mechanic, one of the first things to consider is how much education you need. There were two major … T. H. G. Megson (Figure 2) Helicopter airframes consist of the fuselage, main rotor and related gearbox, tail rotor (on helicopters with a single main rotor), and the landing gear. The landing gear absorbs the forces imposed on the aircraft by takeoffs and landings. The wings are prevented from folding over the fuselage by the resisting strength of the wing structure. By contrast, propellers and rotating airfoils of an engine on an airplane are not considered part of the airframe. Bending increases when the aircraft makes a carrier landing. A simplified explanation of how a helicopter flies is that the rotors are rotating airfoils that provide lift similar to the way wings provide lift on a fixed-wing aircraft. Bending is a combination of tension and compression. Like Wood, cement, hydrogen, air and water are all examples of materials. Metallic Aircraft Construction Stress and Structure – Aircraft structure must be strong, lightweight and streamline. This force creates a torsional stress in the fuselage. The skin of aircraft can also be made from a variety of materials, ranging from impregnated fabric to plywood, aluminum, or composites. – Internal structure ... and, for any given aircraft weight, this reduces the stalling speed • The Fowler flap is an example of one which increases the area of the wing. Academia.edu is a platform for academics to share research papers. The ACS trade is an amalgamation of three aircraft maintenance trade (Machinist, Aircraft refinisher, and Metal fabrication). Compression is the opposite of tension. All aircraft structure must flex slightly to withstand the forces imposed during takeoff, flight, and landing. The trade was officially integrated into the RCAF in … These factors determine the requirements to be met by any material used to construct or repair the aircraft. Solutions Manual . An aircraft built so heavy that it couldn’t support more than a few hundred pounds of additional weight would be useless. joints in aircraft structures are identical: Restoring the damaged structure to a required capability in terms of strength, stiffness, functional performance, safety, service life. Structural members of an aircraft’s fuselage include stringers, longerons, ribs, bulkheads, and more. Aircraft undergo rigorous testing before they can be considered safe and certified for flight to ensure that they can operate how they need to. Introduction: The airframe is the basic structure of an aircraft, design to withstand aerodynamic forces and stresses imposed.
