The invention discloses a helicopter parachute-free air-drop platform sliding track device which is composed of a track, a traction rope and the like and has three states of folding, unfolding locking and track overturning. In the flying process of the helicopter, the device is located in a helicopter cabin and is in a folded state; when air-drop is prepared, a cabin door of the helicopter is opened, the rails are unfolded through the driving devices, when the rails are unfolded to the designated position, the locking mechanism is triggered, locking between the rails is achieved, and after the air-drop platform reaches the working position of the rails, the rail dropping plate is overturned under the action of the overturning mechanism, so that the air-drop platform smoothly completes air-drop; and after air-drop is completed, the rail is overturned and restored through the driving device, the locking state is relieved through the traction device, the rail is pulled to return to the folded state and is retracted into the cabin, and the whole air-drop task is completed. According to the device, the situation that the inclination angle of the platform relative to the rear cabin door is too large during air-drop can be well avoided, and it is guaranteed that the air-drop platform is evenly stressed when making contact with the ground.
本发明公开了一种直升机无伞空投平台滑行轨道装置,该装置由轨道、牵引绳等组成,具有收拢、展开锁定和轨道翻转三个状态。在直升机飞行过程中,装置位于直升机机舱内部,处于收拢状态;准备空投时,直升机舱门打开,通过各驱动装置使得轨道展开,当轨道展开到指定位置,锁定机构触发,实现轨道之间的锁定,空投平台到达轨道的工作位置后,轨道投放板在翻转机构的作用下进行翻转,使空投平台顺利完成空投;空投完成后,通过驱动装置进行轨道的翻转复原,通过牵引装置解除锁定状态,牵引轨道回到收拢状态,回收到机舱内部,完成整个空投任务。本发明装置能够很好的避免空投时平台出现相对后舱门倾角过大的情况,保障空投平台在接触地面时受力均匀。
