Brake system

A brake system comprising an air vehicle (V);

• a plurality of wheels located on the air vehicle (V) and enabling movement of the air vehicle (V) on the ground (Z);
• at least one rotating structure located on the air vehicle (V) to be concentric with the wheel and performing rotational movement with the wheel;
• a friction element which contacts and suppresses the rotating structure, thereby creating a braking force and enabling the air vehicle (V) to be decelerated;
• at least one actuator triggered by an electric motor (E) such that pressure of the hydraulic fluid (H) therein changes, thus enabling the friction element to be moved towards or away from the rotating structure;
• a chamber in which the hydraulic fluid (H) required for the operation of the actuator is stored;
• a control unit which controls movement of the actuator and pressure of the hydraulic fluid (H) based on the command transmitted from the user and/or flight control software, and adjusts the amount of braking force applied to the air vehicle (V), wherein a piston located to control the hydraulic fluid (H) passage between the actuator and the chamber by acting on the actuator;
• an opened position (O) in which the piston allows the hydraulic fluid (H) passage between the chamber and the actuator;
• a closed position (C) in which the piston is positioned to prevent the hydraulic fluid (H) passage between the chamber and the actuator, wherein the piston is moved to be brought from the opened position (O) to the closed position (C);
• the control unit which enables the piston to be brought to the opened position (O) and kept there for a time predetermined by the manufacturer in order to adjust the amount of the hydraulic fluid (H) when the braking force applied to the air vehicle is stopped, and enables the piston to be brought to the closed position (C) such that the hydraulic fluid (H) remains substantially in the actuator prior to the next braking command.
