What is the function of the hydraulic reservoir in the landing gear system?

The hydraulic reservoir in the landing gear system plays a crucial role by supplying hydraulic fluid. The reservoir acts as a storage container for the hydraulic fluid that is necessary to operate various components of the landing gear system, including the extension and retraction mechanisms.

When the landing gear is deployed or raised, hydraulic fluid from the reservoir is pressurized and directed to the hydraulic actuators and cylinders responsible for moving the landing gear. This process ensures that the gear operates smoothly and efficiently during takeoff, landing, and taxiing. The proper function of the hydraulic reservoir is essential for maintaining the effectiveness and reliability of the landing gear system, as any interruption in hydraulic fluid supply could impact the operation of the landing gear.

While the cooling of the hydraulic system, filtering contaminants, and electrical energy storage are important aspects of hydraulic systems, they are not directly functions of the landing gear hydraulic reservoir itself. The reservoir primarily focuses on ensuring an adequate supply of hydraulic fluid for the operation of the landing gear.
