I have 27 years experience in web research and writing technical articles. I am also very good in English. I am mature, 52 years old, therefore take assignments very seriously. I hold a masters degree. I will deliver your work on time. SAMPLE ARTICLE - AVIATION MECHANIC
The work of an aviation mechanic is repair, replacement, servicing of mechanical and electrical parts of airplanes and helicopters and conducting periodic checks on the vehicles to ensure proper performance.
They may specialize in engines, landing gear, cabins, electrical repair, or communication, aircraft control devices or air conditioning.
Aviation mechanics find jobs in aircraft manufacturers, aircraft repair servicing workshops, airline companies, military and airforce. An aviation mechanic may also set up own workshop and business.
The student of aviation mechanics will learn the systems that make the aircraft function. They will be taught about the propulsion system, electrical system, electronic system, landing gear, fuselage, wing, and control surfaces (ailerons, landing flaps, tail).
The fuel tanks are carried in the wings. The landing gear consisting of the wheel, hydraulic shock strut designed to reduce the descent velocity at touchdown to zero but avoiding accelerations that would be uncomfortable to the passengers, or impose destructive high stresses on the airplane structure, the brakes and pitch propellers, which are rotated in the reverse direction to help cut the speed of the plane.
The fuselage houses the cargo and passenger compartments, and also acts as a pressure cabin allowing the atmospheric pressure at ground level to be maintained against the very low high altitude pressure.
The student will learn about the control surfaces consisting of the wings, vertical tail and horizontal tail surfaces. 75% of the wings are fixed and 25% consist of movable elements that allow the pilot to control the plane. The aileron allows the pilot to control the lateral and rolling motions of the plane. The landing flap gives the wings added lift to reduce the landing speed and permits fairly high angle of descent without gaining excessive speed. The flaps are also used for the same purpose during take off. Directional or yawing control is provided by a rudder fixed on the vertical tail surfaces and the pitch control provided by the horizontal tail surfaces.
The student will learn about the propulsion system consisting of the engine and the fuel. The fuel is the source of energy. The engine is the mechanical device by which the fuel’s energy is transformed into the propulsive force needed to drive the plane. Airplanes are propelled by accelerating a gas in the opposite direction as flight of the plane.
There are two types of airplane propulsion systems - those in which the rearward acceleration of gas is produced by the rotation of propellers driven by the plane’s engines and those in which the gas is accelerated rearward within the engines themselves – jet propulsion. For reliability planes normally have more than one engine – mainly four. The student will learn about the three types of internal combustion engines now in use – reciprocating engine for propellers, turbine engine for compressor which have no propellers and have the accelerated gas discharged directly from the engine, ram jet engine which consist of diffuser compressors and combustor burns air and discharges it through an exhaust nozzle, and rocket engine which does not use air for burning fuel and propulsion but carries its own oxidizer and is therefore independent of earth’s atmosphere.
The techniques used in this fulfilling carrier are easy to master and it does not take long to develop the skills. Manufactures produce the parts and service manual for all models. The operation manuals give details of all the parts in illustrative diagrams which are simple to understand. The manual also gives a detailed explanation on how to remove and replace the parts, when to replace them and under what conditions they give optimum performance.
One should not be intimidated by the terminology used. The training will help in grasping their meanings with a short time. They are just a language used to refer to the systems of operation and the parts.
