AI Technical Summary
The existing tail rotor collector ring has a complex structure and is heavy, and dynamic faults in the anti-icing heating components are difficult to detect, making testing and maintenance inconvenient.
The tail rotor adopts a coaxial design with the rotor assembly and stator assembly, combined with the brush box and conductive ring assembly, and integrates a current detection circuit. The integrity of the tail rotor heating circuit is monitored in real time through the circuit board, and it is connected to the drive shaft through a clamp, simplifying the structure.
It achieves a lightweight design, simplifies the installation and disassembly process, enables real-time monitoring of the integrity of the tail rotor heating circuit during high-speed rotation, locates faulty blades, and improves testing and maintenance efficiency.
