Variable-Pitch Mechanism
A mechanical device that adjusts lift by changing the installation angle of blades, commonly used in helicopter and single-motor drone designs.
Timeline (last 90 days)
A variable-pitch mechanism adjusts lift by changing the blade installation angle without changing motor speed; adding cyclic pitch allows the rotor disc to tilt and generate pitch and roll moments.
The cost of a variable-pitch mechanism is a large number of precision linkages, bearings and servos, making maintenance far more complex than electronic speed control, but its control bandwidth and response linearity perform better in hover.
