| 发明名称 | Controlling blade pitch angle | ||
| 摘要 | A method and arrangement of controlling blade pitch angle of a set of rotor blades. The method comprises providing a target blade pitch angle to a controller mounted on the rotor; measuring the speed of rotation of the rotor using a rate gyro mounted on the rotor; calculating the blade pitch angle required to match the target blade pitch angle by summing the target blade pitch angle and the measured rotational speed; and actuating the blades to the calculated blade pitch angle. | ||

| 主权项 | 1. A method of controlling blade pitch angle of a set of rotor blades provided on a rotor, comprising: providing a target blade pitch angle to a controller mounted on the rotor; measuring a speed of rotation of the rotor using a rate gyro mounted on the rotor; calculating a blade pitch angle required to match the target blade pitch angle based on the target blade pitch angle and the measured rotational speed of the rotor; and actuating the blades to the calculated blade pitch angle. | ||
