Aircraft Icing Research Paper Example | Topics and Well Written Essays - 1750 words
Aircraft Icing - Research Paper Example Icing does not spare any type of aviation. In extreme cold conditions, ice forms naturally. An aircraft, despite its size and shape, has no control over formation of ice over its surface. Deicing and anti-icing treatment helps ward off icing on aircraft surface. But even with these treatments, it is necessary to be on the lookout for sneaky icing to happen unobtrusively. No region in the world can boast of ice-free aviation condition. Icing is not known as the silent killer for nothing. It has taken heavy toll arising from complacency and lack of vigilance. Early in the 1940s when the problem of icing began to get noticed, people in the aviation industry did not view it very seriously. Aviation was not a huge industry then. However, when the industry began to grow in leaps and bounds in the late 1970s, icing problem began to get noticed. Customer base grew. It became a demanding market. It became necessary for flights to be frequent and time adherent. It was then that problems such as icing began to get noticed in the way it should. On 13 January 1982, the Air Florida flight 90 accident at Washington National Airport sounded alarm bells to the lethal hazards of ground icing (William M. Leary). The clear and smooth ice with air pockets that has the lumpy and translucent appearance. The more the accretion, the less the glazed ice takes the form of the wing. This ice is clear and hard to break and is more transparent. Mixed ice Rime ice and clear ice together form the mixed ice. Conditions that cause icing High humidity and the low winter freezing levels are the main causes of icing. The airframe icing are caused when planes are flying through visible cloud, rain and drizzle and the temperature reaches at a point zero or sub zero. The aerodynamic danger The weight of ice on the body of the plane causes accretion; the accretion occurred is asymmetrical that causes higher uncontrollability to the plane and aircraft movements. The visibility in front of the plane is also lost because of the ice. The propeller blades of the plane if iced causes reduction in thrust and may result in danger by causing imbalance to the movements of the plane; surface movement may be cut down because control of the plane may be lost, causing flutter. The antennae of the plane that helps in bridging communication may render ineffective. The speed of the plane may be stalled because its flaps may be extended. Technology of icing detection Anti icing technology The technology is used at a pre icing stage, to avoid ice to shape form on the body of the plane. Various areas of plane are heat up including carburetor heating, prop heating, pilot heating, fuel vent heating, and wind shield heating, etc. Deicing This procedure is used after the icing conditions have engulfed the plane. Surface deicing equipment is to prevent any ice from inhibiting the
