The invention discloses a helicopter ground driving method. The helicopter ground driving method comprises the following steps that the minimum output power of an engine at the low ground rotating speed is calculated on the premise of analyzing and determining the low ground rotating speed of a helicopter, the required power of the whole helicopter is calculated and analyzed at different total distances, and by comparing the output power with the required power, a total distance value meeting the requirements of matching the output power of the engine and the required power of a rotor system is determined; when the helicopter is started slowly on the ground, the total distance is increased to a corresponding position in a slow-ground state, so that the power input and output of the whole helicopter are balanced during slow-ground operation; and in the process that the engine flies slowly from the ground, the total distance is lowered, the needed power is reduced, and therefore the ground driving process is completed. The method can effectively avoid possible damage to the engine and the helicopter due to mismatching of the output power of the engine and the absorption power of therotor system in slow ground operation of the helicopter.
本发明公开了一种直升机地面开车方法,包括:在分析确定直升机地慢转速的前提下,计算地慢转速时发动机的最小输出功率,计算分析在不同总距下全机的需用功率,通过对比输出功率和需用功率,确定满足匹配发动输出功率和旋翼系统需用功率的总距值;在直升机地慢开车时,在地慢状态下,将总距提到相应位置,使得地慢运转时的全机功率输入输出平衡;在发动机从地慢到飞慢过程中,将总距放低,降低需用功率,从而完成地面开车流程。本发明方法可以有效地避免在直升机地慢运转中由于发动机输出功率和旋翼系统吸收功率不匹配可能对发动机和直升机造成损伤。
