The invention provides a thrust generating device. A controller (14) of a thrust generating device (10) executes either a first control for controlling thrust by changing the pitch angle of each blade (28) while maintaining the rotational speed of a propeller (26) at a reference value, or a second control for controlling thrust by changing the pitch angle of each blade (28) while maintaining the rotational speed of the propeller (26) at a reference value. In the second control, a thrust force greater than the thrust force generated in the first control can be generated by making the rotational speed of the propeller (26) greater than the reference value. Therefore, the noise generation opportunity can be reduced, and the required thrust can be obtained.
本发明提供一种推力产生装置。推力产生装置(10)的控制器(14)执行第1控制和第2控制中的一方,其中,在所述第1控制中,通过在将螺旋桨(26)的转速维持在基准值的同时使各桨叶(28)的俯仰角度变化来控制推力;在所述第2控制中,通过使螺旋桨(26)的转速大于基准值可以产生比在第1控制中产生的推力大的推力。据此,能减少噪声的产生机会且能得到所要求的推力。
