The invention belongs to the technical field of transmission, and particularly relates to an active anti-strike oil loss system and method for a helicopter transmission system. The system comprises atransmission device (1), a vacuum generator (2), a sensor (3) and a controller (4), and oil is contained in a shell of the transmission device (1); one end, provided with the inductive probe, of the sensor (3) extends into a shell of the transmission device (1); a negative pressure opening of the vacuum generator (2) extends into a shell of the transmission device (1); the position of a negative pressure port of the vacuum generator (2) is higher than the maximum liquid level of oil in a shell of the transmission device (1); and the controller (4) is electrically connected with the sensor (3)and the vacuum generator (2) respectively. The vacuum generator generates negative pressure to inhibit transmission system oil loss caused by bounce and other reasons, so that the survivability of helicopters and other aircrafts in a harsh battlefield environment is effectively improved, the safety of the aircrafts is guaranteed, and the life safety of pilots is protected.

本发明属于传动技术领域，具体涉及一种直升机传动系统主动抗弹击失油系统及方法。包括传动装置(1)、真空发生器(2)、传感器(3)、控制器(4)，所述传动装置(1)壳体内盛有油液；所述传感器(3)具有感应探头的一端伸入所述传动装置(1)壳体内；所述真空发生器(2)负压口伸入所述传动装置(1)壳体内；所述真空发生器(2)负压口位置高于所述传动装置(1)壳体内油液的最大液面高度；所述控制器(4)与所述传感器(3)和所述真空发生器(2)分别电连接。本发明通过真空发生器产生负压抑制弹击等原因造成的传动系统油液流失，从而有效提升直升机等飞行器在严苛战场环境下的生存力，保障飞行器安全，保护飞行员生命安全。
