Adjustment device for adjusting the pitch angle of the propeller blades, control functions that you can perform a variable pitch propeller, in a computer, and how to adjust the pitch angle of the propeller blade

摘要

First blade pitch angle range of positive pitch angle, the propeller blades to generate a driving force, and second blade pitch angle range, the propeller and-rotate in the same direction, the pitch angle of the propeller blades of variable pitch propeller An adjusting device to adjust in the third blade pitch angle range of negative pitch angle that the propeller blades to generate a reverse thrust in the state, said second blade pitch angle range, the first and the first blade pitch angle range It is an intermediate range of the pitch angle that exists between the three blade pitch angle range, it generates a low reverse thrust and range, a positive pitch angle that produces pitch angle range is very small tensile force with respect to the blade, the low driving force In the adjustment device which can contain a range of negative pitch angles to, the third blade pitch-angle range from the first to the propeller blades, or to adjust the first blade pitch-angle range from the third, actuated by the actuator it is, the propeller blade in the first group A are allowed to pass and the second blade pitch-angle range, at least, it is designed the propeller blades in another group so that there is a range of blade pitch angle positive. And method of variable pitch propeller control functions available are also described in the computer corresponding to this.
