What are Aircraft Hydraulic Systems?
Aircraft hydraulic systems are key aircraft systems that use pressurized hydraulic fluids to transfer power and control functions. Hydraulic systems actuate landing gear, flight controls, brakes, steering, and thrust reversers. The aircraft hydraulic systems offer controlled and reliable actuation in harsh operating conditions. Hydraulic system design focuses on pressure maintenance, system reliability, and safe aircraft operation.
How Aircraft Hydraulic Systems Work?
The hydraulic systems of an aircraft make use of pressurized fluid in order to facilitate the motion of the aircraft components. A hydraulic pump pumps pressurized fluid into a set of lines connected to the moving component. The actuator will then use the pressure of the fluid to create motion. Depending on the airplane's design, the movement can be used to control the flight controls, landing gear, brakes, steering, or thrust reversers. It also monitors the movement of components for positioning purposes.
Step-by-Step Process
Command from Pilot: The pilot issues the command by means of the control that is, for example, to extend aircraft landing gear systems or manipulate flight controls.
Pressurization of Fluid: The hydraulic fluid is pressurized through a hydraulic pump and supplied to the system.
Transport of Fluid: The pressurized fluid flows through hydraulic pipes to the designated component of the airplane.
Activation of Actuators: The actuators work by using the hydraulic pressure to exert mechanical force on the component.
Monitoring the System: The valves and sensors maintain the pressure and ensure that the process is done properly.
Efficient Operation of the System: After the process, the hydraulic system keeps working efficiently for further commands.
Aircraft Hydraulic Systems Components and Functions
There are different components that make up the hydraulic system of an airplane. Each of the components serves a unique purpose within the hydraulic system. Pumps supply hydraulic pressure for the proper functioning of the system. Reservoirs contain the hydraulic fluid. Accumulators supply hydraulic power when extra pressure is required. Actuators convert hydraulic pressure into mechanical movement. The valves direct the flow of hydraulic fluid in the system. The filters clean the fluid of impurities. The performance of these components influences the reliability of the hydraulic system. The design of the components also differs depending on the aircraft and pressure in the system.
Pumps, Reservoirs & Accumulators
Pumps generate the pressure needed to transport the hydraulic fluid in the system. They get mechanical energy from the aircraft, then convert this energy to hydraulic fluid energy. Reservoirs house the fluid that is used by the system. In addition, they give room for fluctuations in fluid volume. Accumulators store hydraulic fluid at a certain level of pressure. They are able to provide extra fluid in case of high system demands. They can also help in maintaining fluid pressure in cases of increased demands.
