Aircraft maintenance and structures - Assignment Example This is true for the combination of the reduced performance factor like wet and long grass, uncoordinated or severe manoeuvres, tire engine, turbulence, emergency situations, and high ambient temperatures (Seabridge & Moir, 67). The performance of an aircraft and the characteristics of handling are all influenced by the cg and the gross weight. If different pilots could get to know and provides respect to this facts, the aviation accidents could significantly reduce. An aircraft that is improperly balanced or overloaded needs requires great consumption of fuel, and power for the maintenance of flight. This will affect the controllability and stability. The absence of appreciation to the balance and weight on the aircraft performance specifically the combination of the performance factors. The aircraft performance is depended on the wing airfoil design, the speed of movement of the wing, and the air density. It is the aircraft wing design that is the limitation of the quantity of the available lift and the existing power from the engine. This may limit the movement speed of the wing. The engine efficiency or the wing combination is minimum in situations of a less dense air than the standard day. In this case, each and every pilot is expected to ascertain the fact that during pre-flight preparation the gross weight of the aircraft falls in the category of the safe limit of the flight when the aircraft performance is considered. The pilots need to understand that the weight of the baggage cargo together with the fuel load is to be adjusted accordingly to give the safety margin. This means that for general aviation aircraft, it may not be easy to have all seat filled, to have the baggage capacity loaded, carry full fuel and maintain the approved weight and balance of cg. For the six-planes airplanes, the tanks of fuel may not be filled to capacity whenever a full set of passengers

Research and prepare a report about how the application of Essay

Research and prepare a report about how the application of gravitational concepts has helped astronomers - Essay Example and even how to calculate the mass of the sun without travelling to them but through application of gravitational laws (Topper, 2012).They have discovered gravitation lensing and even determined the mass of galaxies. More to this is the discovery of Massive Compact Hallo Objects (MACHOs), primarily recognized as brown dwarf stars while some are regarded as black holes (Kyle, 2010). These and others are examples of discoveries that the astronomers have aided by the application of the gravitational concepts. Through gravitational concepts, astronomers have been able to discover the cosmic microwaves whereby in 2002, a team led by Dr. Kovac discovered the polarization of these microwave radiations (Kyle, 2010). Gravitational waves that are produced as a result of moving masses like those of stars or black holes normally described as ‘ripples in space-time’ have been discovered by the astronomers by the use of interferometers which detects these slight changes in space-time (Topper, 2012). Understanding the gravitational waves has helped the astronomers in explaining certain events such as the birth of black holes and the death of stars. They can therefore be able to tell how the universe began as well as what the future holds for us. This has been aided by application of gravitation concepts by astronomers (Longair, 1986) Gravitation lensing is another thing that astronomers have discovered as a result of understanding the gravitational concepts. This is bending of the light rays by a mass object extending far in the sky, which causes these light rays to be focused somewhere else through its gravitational field (Morison, 2008). According to the research done, the greater the quantity of the body, the sturdier the gravitational field created and thus the greater the bending of these light rays will be. Lensing has been useful in verifying the existence of dark matter which is the determinant of how clusters and galaxies form and develop. Astronomers have
