HYDRAULIC SYSTEMS FOR AIRCRAFTS

HYDRAULIC SYSTEMS FOR AIRCRAFTS

Abstract

The main aspect of designing an aircraft is to reduce its weight. Hydraulically operated systems are comparatively light in weight from the other systems used in aircraft. It can provide unlimited power for various operations, and high power producing capacity is the major advantage of hydraulic power systems.

The operations such as wing-flap control, landing-gear, braking systems requires very high safety and hydraulically operated systems ensures the safety.

Introduction

PRINCIPLE OF HYDRAULICS:

Hydraulics is division of science of fluid mechanics which include the study of liquids and their physical characteristics, both at rest and in motion. The type of hydraulics applied to aircraft and other aerospace-vehicle system is called power hydraulics because it involves the application of power through the medium of hydraulics.

Among the use of hydraulic systems in aerospace vehicle systems are the operation of landing gear and gear doors, flight controls, cowl flaps, and wide variety of other devices requiring high power, quick action, and/or accurate control.
What is hydraulic system?

It is system where liquid under pressure is used to transmit this energy. Hydraulics takes engine power and converts it to hydraulic power by means of a hydraulic pump. This power can be distributed throughout the airplane by means of tubing that runs through the aircraft. Hydraulic power can be converted into mechanical power by means of an actuating cylinder, or turbine.
