Basic Hydraulic Principles

Hydraulic systems provide a means of remotely controlling a wide range of components by transmitting a force through a confined fluid.

Because hydraulics can transmit high forces rapidly and accurately along lightweight pipes of any size, shape and length, they are the prime source of power in aircraft systems such as flying controls, retractable undercarriages, flaps, and wheelbrakes.

The basic principle behind any hydraulic system is very simple - pressure applied anywhere to a body of fluid causes a force to be transmitted equally in all directions, with the force acting at right angles to any surface in contact with the fluid. This is known as Pascal’s Law.
