TASK 1 In this scenario demonstrate your knowledge of least three users of a pneumatic system in an aircraft. (P1) 1. Air Conditioning: Air conditioning is necessary in order to have air in the cabin, which is necessary for human breathing. In order to achieve this air ventilation must maintained to a certain degree to allow air to enter and leave the cabin. The minimum rate needed in the cabin is 0.4Ib (0.18kg)/passenger/minute (JAR25). The air needed per person. It is important also to control the temperature the air in the cabin need to balance in relation to hot and cold air, which is in the cabin. The temperature needed for the cabin is between 60°F - 80°F and relatively humidity must lie between 30%-40% because of the water evaporation of the air in the cabin. This helps to control through dryness caused by lower or higher humidity or condensation of windows. Before air going…show more content…
Pneumatic System: Pneumatic system has rubber boots, which has several tubes that inflates and deflates. The system is made from soft pliable of rubber fabric and neoprene used for the outer ply. Neoprene withstands friction and wearing also can disperse static electricity. Thus becoming a de-icing system. When icing, the rubber boot inflates some tubes creating a swell on the leading edge, which breaks the ice apart and blown away by the airflow. A vacuum helps to shape the airfoil back deflating the boots. 4. Fluid System (Chemical): Fluid system consists of de-icing fluid, which is stored in a tank. When there is a need it is taken by an electrical driven gear pump to the micro filters and distributed through many number of porous stainless steel distributer panels. The panels are made in the shape of a wing and tail unit and built into the leading edge. Each panel has a number of pours where fluid is passed to the outer skin after passing into a cavity and through a porous plastic sheet. The fluid makes the ice to weaken loosening the ice made and then wiped by the
