The invention relates to the technical field of helicopters, and discloses a helicopter rotor tail rotor failure protection system and a helicopter.The helicopter rotor tail rotor failure protection system comprises a jet parachute, a protection device and a parachute hatch cover, the protection device comprises a first cavity and a second cavity, the first cavity is used for containing the jet parachute, and the fixed end of the jet parachute is connected to the first cavity; the first cavity and the second cavity are separated through a partition plate, a jet opening is formed in the partition plate and corresponds to the jet umbrella, a sealing cover driving device is arranged in the second cavity, and a sealing cover is arranged at the top end of the sealing cover driving device and covers the jet opening. The sealing cover driving device is used for driving the rotor wing sealing cover to cover or be away from the jet flow opening, the second cavity is used for being filled with high-pressure gas, and the parachute cabin cover is an openable parachute cabin cover arranged at the opening end of the first cavity. Through the arrangement, enough lift force can be provided for the helicopter to balance the gravity of the helicopter, the original stable flight state is maintained to the maximum extent, and the safety of the helicopter is improved.
本发明涉及直升机技术领域,公开了直升机旋翼尾桨失效保护系统及直升机,包括射流伞、保护装置、伞舱盖,保护装置包括第一腔室和第二腔室,第一腔室用于放置射流伞,射流伞的固定端连接在第一腔室上,第一腔室与第二腔室之间通过隔板隔开,隔板上开设有射流口,射流口与射流伞对应,第二腔室内设置有密封盖驱动装置,密封盖驱动装置的顶端设置有密封盖,密封盖盖设在射流口上,密封盖驱动装置用于驱动旋翼密封盖覆盖或远离射流口,第二腔室用于填充高压气体,伞舱盖为设置在第一腔室的开口端的可开启式伞舱盖。这样设置,能够为直升机提供足够的升力以平衡直升机自身的重力,最大限度维持原有的平稳飞行状态,提高了直升机的安全性。
