    For actuating aircraft control system and motor, and other systems and units for aircraft use various forms of energy with considerable power consumer. Depending on the type of energy used are hydraulic, gas and electric. Each grid has specific properties and has certain advantages. On modern airplanes is important hydraulic system, the rapid development and a sharp increase in capacity that is due to the extensive use of hydraulic actuators control surfaces. The hydraulic system provides aircraft management systems and mechanisms that determine the safety of the flight. Reliability, survivability and durability achieved perfection hydraulic design units, multiple redundancy, as a source of energy and hydraulic drives, automation control, monitoring and operation information of the crew. The use of hydraulic actuators on the aircraft due to the relatively small weight and size, great speed and low inertia of the actuator (unlike electric motors). Weight and dimensions of the hydraulic unit is approximately 10-20 percent of the weight and dimensions of the electrical machine of this appointment and the same capacity. Hydraulic systems can develop a significant effort for a large speed, provide a simple fixation of the intermediate positions of the actuators. Hydraulic systems are used to control the stabilizer and rudder, for cleaning and landing gear, landing mechanization and other consumers. The disadvantages of the hydraulic system may include a relatively small mass units, pipelines, and the working fluid, the dependence of the units on the ambient temperature. Damage to components and piping associated with the loss of integrity can result in the release of fluid from the hydraulic system, which will lead to failure hydro system.
