Rotor Brake Components
1 / 2Pages

Rotor Brake Components Rotor Brake systems provide pressurized fluid to the brake caliper by activating an operator handle to slow the rotation of the Helicopter rotor blades for engine shutdown or startup. Master cylinders, reservoirs, accumulators, control valves, and servicing provisions are included in many systems. Operational Characteristics: Provides hydraulic pressure and stored volume to actuate and hold a brake caliper to prevent movement of helicopter rotor blades Operated by mechanical handle (integral or remote) Detent provided in "Unlocked” position and locking device provided to hold lever in "Locked” position Major Components - Mechanical operator and linkage - Spring loaded accumulator - Housing - Actuating piston - Service features - Valves Design Characteristics: • Operating pressure up to 1,000 psig • Dual output pressures available, solenoid actuated • Bypass features can compensate for normal brake wear • Multiple mounting options Arkwin Industries is the technical expert in all things hydraulic for aerospace and defense.
