The choice of the right material for a particular overhaul job stresses understanding of the common physical and chemical properties of different metals. Another aspect of aircraft maintenance and repair is that aircraft hardware is frequently ignored since of the insignificant size of the parts. But, selection of right hardware for the use in aircraft is very vital for the efficient operation and safety of any aircraft. The goal of this essay is to emphasize the importance of material, its various process and hardware selection for the use in aircraft structures (faa.gov, ND). Introduction The earlier aircraft materials must refer timber as the first materials used to create a power-driven aircraft. The Wright brothers involved mainly of Sitka spruce and bamboo fastened and bolted together to make a canvas-covered assembly. Aircraft made by wooden material were very successful in the initial years of flying. Currently, timber is only fit for fairly small aircraft. As the requirement for larger aircraft became unavoidable for the modern society, materials with superior specific strength come to be essential. Currently airplane consists mainly of aluminum alloys with steel, titanium alloys and polymer compounds. The equilibrium of materials does rest on on the kind of airplane as military fighter airplanes have much higher amounts of composites and titanium alloys. In this essay more emphasize is given to aircraft materials and its different processes. Pure aluminum and Aluminum alloys Airplane must be made of material with lesser weight to carry more loads and to reduce fuel consumption. The more travelers an airplane can transport the more income an aircraft corporation can create. At the same time as pure aluminum have less weight, very good corrosion resistance and exceptional thermal and electrical conductivity but it is weak and ductile to be used on aircraft structure in its pure form. The credit goes to Dr. Alfred Wilma, a German metallurgist, who found out that aluminum alloyed with copper and heat treated properly can be made much sturdier. The alloy of aluminum with 4% copper is said to be Duralumin and the heat treatment procedure is termed as precipitation hardening. After this Duralumin have characteristically little specific gravity and great strength (450 MPa). Since it is restricted to a maximum amenity temperature of around 660°C supplementary heat treatable aluminum alloys have been developed for aircraft use. These comprise a variety of intricate aluminum-zinc alloys which improve the maximum strength of several aluminum alloys. These alloys have used for contemporary aircraft design in which the skin of the fuselage and wings are stressed aluminum alloy parts that lessen the total heaviness of the aircraft. The disadvantage of the aluminum alloys discussed above have a drawback of not being as corrosion resistant as compared to pure aluminum. Therefore a thin coating of pure aluminum is usually fused to either sides of the alloy and is called Alclad aluminum alloy. Even though titanium is very costly it is used where great strength is required in load bearing applications for example, landing gear and engine escalating supports

From the literature, it is only but Graziano et al. (2011) who conducted a study on 141 girls and 127 boys to evaluate how childhood obesity can be predicted by cardiovascular regulations. However, in this study, the researcher used a study population of boys and girls within the age limit six and twelve and the key objective was ascertaining if there was a significant difference between the African American Children and the white American children.
Materials have evolved from wood to composites. Some of the commonly used materials include aluminium alloys. The choice of these materials has been influenced by their lightweight, durability and ease of manufacture. The paper will discuss some of the materials used in aircraft construction.
Due to the large stiffness to weights ratio and strength to weight ratio aluminium and titanium have been the used predominantly for the past several years.( Aitchison Leslie, 1924) However of late, composite materials have found increased acceptability since this causes a saving of 30 to 40 percent in weight compared to aluminium and titanium.
Generally, there are three major kinds of incidents. The most critical is the high-impact crash. Cases are mid-air collisions or explosions in mid-air. There are more or less no survivors. However there is still a need of massive search operations.
Low-impact crashes are sometimes survivable, although can have a disastrous outcome.
This papers reviews the latest technology used for maintaining the aircraft and how maintenance has change to adopt the latest technology advances. Closing with the future of aircraft maintenance.
Aircraft Maintenance technology relates to the actions required to improve the airworthiness and the designed-in reliability of an aircraft and its systems, subsystems, and components throughout the life cycle of the aircraft.
It’s a wonder that during this accident there were not many victims. The cause of the accidents was rapid decompression, which happened because 24,000 feet section of the fuselage tore from the airplane /Miller, 1990/.
In spite of not numerous victims this air

The current focus on sustainable development in concrete technology aims at producing more environmentally friendly cement, which spawns less carbon dioxide and expends less energy. Such environmentally favorable cement is what is referred to as “green
On the other hand we have structure B which is a 800 circular column with a thickness of 50 cm. the total volume for this structure is 400. The analysis period for this structure is similar to that of the above structure. This structure is also
Current engineers, however, apply automated machines in undertaking manufacturing works. Old machines are no longer applicable in the manufacturing process; automated machines outdo the role of old machines. Markillie emphasizes on the introduction of 3D
