And the throwing separation device is used for cutting off the connection between the lifting rope system 3 and the aircraft.

In the present embodiment, part of the suspension rope roping 3 is connected to the nose of the aircraft and the other part of the suspension rope roping 3 is connected to the tail of the aircraft. As shown in fig. 1, three lifting rope ropes 3 are connected to the head part, the middle lifting rope 3 is a front lifting point lifting rope, and the lifting rope ropes 3 on both sides are side vertical plate lifting point lifting ropes. The tail part is connected with two lifting rope ropes 3 as a rear lifting point lifting rope.

In the embodiment of the invention, two sides of the hoisting frame 1 are respectively provided with a posture adjusting driving device 4 to respectively drive the hoisting rope systems 3 at the two sides to be wound and released so as to realize the adjustment of the lift-off angle.

In the embodiment of the invention, the whole hoisting frame 1 can adopt a TA4 titanium alloy material truss structure design so as to greatly reduce the weight of the hoisting frame structure.

In the embodiment of the invention, the throwing separation device can be formed by arranging a plurality of cutters in series through redundancy.

The diameter of the flame cutter may be, for example, 12 mm. The rope ring 6 is cut off by the cutter 5, and then the throwing separation of the aircraft can be realized.

In order to further ensure the safety and reliability in the attitude adjusting and throwing process, the hoisting flight attitude adjusting and throwing device can also comprise a tension measuring device and a telemetering system.

The tension measuring device is used for measuring the tension of the lifting rope system 3 and transmitting the tension to the ground command room in real time, and fig. 3 schematically shows a tension change curve diagram of the lifting rope system at each lifting point in the aircraft attitude driving tilting process provided by the embodiment of the invention.
