P2.1 Determine the properties of air as a fluid power medium for aircraft system. Advantages of Pneumatics over Hydraulics Safety- pneumatic system is very safe because it uses air as main source which is non-flammable and as air is more compressible it can be operated without any support if it is stored the compared to other system this system Light weight- as aircraft should be weight less pneumatic system is suitable because it does not consists of any heavy materials it uses air which gradually decrease the weight and this system does not need return line as is the case with hydraulic fluids Simplicity of design and control- pneumatic machines is easily designed using standard cylinders and other components and operates via…show more content…
Like hydraulics pneumatics is also a type of fluid power application where instead of an incompressible liquid pneumatics employ gas in their system. Hydraulics present certain advantages over pneumatics, but in a given application, pneumatic powered equipment is more suitable for the aircraft for compressed air. P2.2 Explain the function and operation of anti-icing system in aircraft and their associated status indicators in the cockpit. Anti-Icings systems are designed for keep atmospheric ice from accumulating on aircraft surfaces like particularly leading edges such as wings, propellers, rotor blades, engine intakes, and environmental control intakes. If ice is allowed to build up to some significant thickness that can change the shape of the airfoils and the flight control surfaces, degrading the performance, control and handling the characteristics of the aircraft. An anti-icing system either prevents formation of ice or enables the aircraft to shed ice before it can grow to a dangerous thickness. Anti-ice and rain systems…show more content…
Compressor ii. Check Valve iii. Pneumatic actuator Compressor An air compressor is a device that converts mechanical or electrical power into potential energy stored in pressurized air compressor. By one of several methods an air compressor forces more and more air into the storage tank and increasing the pressure. When tank pressure reaches its limit the air compressor shuts off. The compressed air is then held in the tank until called for use. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. Check Valve Check valves are used in both hydraulic and pneumatic systems. in a flap-type pneumatic check valve air enters from the left port of the check valve and compresses a light spring and forcing the check valve open and allowing air to flow out of the right port. But if air enters from the right air pressure closes the valve, preventing a flow of air out from the left port and a pneumatic check valve is a one-direction flow control valve. Pneumatic
