How does the rotor brake system affect the rotor blades post-engine shutdown?

• A. Increases rotor RPM
• B. Helps to stop blade movement quickly
• C. Turns off the electrical system
• D. Prevents hydraulic leaks

Answer: (B)

The rotor brake system is designed specifically to stop the movement of the rotor blades quickly after the engine has been shut down. When the engine is turned off, the rotor blades continue to spin for a short period due to inertia. The rotor brake applies a force to the rotor system, effectively slowing down this movement more rapidly than would occur naturally. This quick stopping of the rotor blades is important for safety reasons, as it minimizes the risk of the blades causing injury to ground personnel or damage to equipment during post-flight operations. By ensuring that the rotors are brought to a stop in a controlled manner, the rotor brake system plays a critical role in the overall safety protocol of helicopter operations. While other options may touch on relevant systems, they do not pertain directly to the specific function of the rotor brake after the engine has shutdown.
