AIRCRAFTS HYDRAULIC SYSTEM AIRCRAFTS HYDRAULIC .ppt (Size: 790 KB / Downloads: 15) INTRODUCTION Hydraulics is based on the fact that liquids are incompressible Hydraulic system is a system where liquid under pressure is used to transmit energy In it a hydraulic pump converts mechanical power to hydraulic power An actuating cylinder converts hydraulic power to mechanical power. DEVICES USING HYDRAULIC SYSTEMS IN AIRCRAFTS Gun turrets Auto pilot Shock absorption systems Dive, landing, speed and flap brakes Bomb bay doors Doors and hatchways Landing gears, wing flaps, etc… PRINCIPLES OF OPERATION Governed by Pascal’s law The oil is in contact with both sides of the piston head but at different pressures. High pressure oil may be pumped into either side of the piston head. The selector valve determines to which side of the actuating cylinder the high pressure oil (red colored side) is sent. RESERVOIR FUNCTIONS Holds reserve supply oil to account for normal leakage, emergency supply of oil, volume changes, thermal contraction of oil, Provides pressure head on the pump, a place to remove air or foam from liquid, air space for expansion of the oil due to temperature changes etc ADVANTAGES It is lighter in weight than alternate existing systems. It is dead beat, that is, there is an absence of sloppiness in its response to demands placed on the system. It is reliable; either it works or doesn't. It can be easily maintained. It is not a shock hazard; it is not much of a fire hazard. It can develop practically unlimited force or torque. |
