Active Noise Reduction System TRIZ Cases
- Fixed-Pitch Tail Boom Motor Matrix for Helicopter Anti-Torque
A tail-boom matrix of fixed-pitch electric motors replaces the tail rotor to cut vortex noise, reduce vibration, and improve anti-torque control.
- Dual Tail Fan Anti-Torque Assembly for Responsive Rotorcraft Yaw
Two tail fans with different rotational inertia combine high anti-torque thrust with fast yaw response in side winds and sideward flight.
- Distributed Fixed-Pitch Tail Rotor Control for Helicopter Anti-Torque
Multiple fixed-pitch motor modules replace the tail rotor to cut vortex interference, noise, weight, and variable-pitch complexity.
