Reasons For Using Hydraulic Power In Aircraft

p.1

Explain the reason for using hydraulic power as major source of energy in nose wheel & landing gear in an Aircraft in the form of written report? A system where the liquid under pressure is used for transmit the energy. This system takes engine power and converts hydraulic power by hydraulic pump. This power will be distributed throughout the airplane and by tubing it runs throughout the airplane this power can be reconverted to mechanical power by actuating cylinder or turbine. Hydraulic system is based on fact that liquid are in compressible.

 Hydraulic pumps converts mechanical energy to hydraulic energy

 A actuating cylinder converts hydraulic energy to mechanical energy

1. Weight As aircraft should be light in weight as hydraulic system is used so that it reduces the space and over all weight which is most essential thing for aircraft as it won’t be having big motors and eventually the weight will be reduced

2. Cheap

As so many operations done in aircraft by hydraulics it needs hydraulic oil which is so cheap and efficient than other systems which also reduces the maintenance cost of aircraft

3. High efficiency

They can produce 25 times greater force than pneumatic cylinders of equal size and they can operate in pressure up to 4000 PSI and which can produce high pressure

4. Shock absorber

An aircraft landing gear acts as shock absorber also it does the both functions while landing when aircraft touches earth the heavy shock is produced and hydraulics
