Parts of an Airplane Operated With Hydraulic Systems

When you look at the parts of an airplane operated with hydraulic systems, you quickly realize the integral role hydraulics play in aviation. Understanding hydraulic systems and the roles they play in operating an aircraft provides insight into the mechanics of flight.

What Is a Hydraulic System?

A hydraulic system uses fluid, usually some type of oil, to transmit power from one location to another within the system. The principal components of this system are the reservoir, pump, valves, hydraulic fluid, motor, and hydraulic cylinder.

The reservoir stores the hydraulic fluid. The pump creates pressure, forcing the fluid to move along the system. Valves control the flow and direction of the fluid. The hydraulic fluid carries the energy from the pump to the motor located at the other end. The motor then converts this hydraulic energy into mechanical energy. Finally, the hydraulic cylinder generates the force required for the operation of the system. The fluid then returns to the reservoir, making the system a continuous loop.

Critical Airplane Parts and the Hydraulic Systems That Support Them

Flaps and Slats

Flaps and slats contribute significantly to an aircraft’s ability to lift off and land safely. The flaps, located on the trailing edge of the wings, and the slats, found on the leading edge, extend and retract by the power of hydraulic systems. When extended, they increase the wing’s surface area and curvature, creating more lift at slower speeds. This mechanism is crucial during takeoff and landing when the airplane moves at lower velocities.

Landing Gear

Sometimes referred to as the undercarriage, the landing gear includes the wheels that the airplane moves around on when it is not flying, allowing it to taxi, take off, and land. The hydraulic system powers the retraction and extension of the landing gear.

Brakes, Spoilers, and Thrust Reversers

The hydraulic systems also operate the brakes, spoilers, and thrust reversers—all vital components for controlling the airplane’s speed and ensuring safe landing. The hydraulic brakes allow pilots to control the speed of the airplane on the ground, which is crucial when taxiing and after landing.

Spoilers, located on the top of the wings, disrupt the airflow over the wings, reducing lift and increasing drag when deployed by hydraulic controls. This action helps slow down the airplane during landing and aids in rapid deceleration on the ground.

Thrust reversers are devices that redirect engine thrust forward rather than backward when engaged using hydraulic controls. This action provides an additional means of slowing the airplane, supplementing the brakes and reducing wear on them.

Other Types of Equipment That Use Hydraulics

Many parts of an airplane depend on hydraulic systems for their operation. Aspiring engineers studying these systems will gain valuable insights into the mechanical wonders of flight.

If you’re interested in hydraulics but aircraft aren’t your thing, there are many other types of heavy equipment and machines that use hydraulic systems. These include bulldozers and excavators, cranes, and forklifts. Metalworking machines and pressurized fluid systems like press brakes and metal stamping or punching machines also use hydraulic power. And hydraulics power some ships’ steering systems. There are many avenues to explore how hydraulic systems power the machinery and transportation upon which we all depend.
