Description
Technical Field
The invention relates to the field of flight suspension. And more particularly to a test chamber hanging device for a fuse low-altitude hanging test.
Background
The traditional fuse low-altitude hanging test is that a test nacelle is hung on a helicopter by using a steel wire rope, and the helicopter is used for towing and flying. In the flying process of the helicopter, a tester utilizes a hatch and a hand-cranking device in the middle of the helicopter to lower the test nacelle for a certain distance, and the helicopter performs dive and pull-up flying according to the required gliding gradient according to the indication of a height meter on the nacelle so as to obtain different sea-sweeping and ground-sweeping heights of the fuze. The main disadvantages of suspending the test car with wire ropes are: because the lifting rope has certain toughness, when the helicopter drags and flies at a constant speed to the test chamber, the lifting rope is in a stable parabola shape; when the speed of the helicopter changes, the form of the lifting rope also changes correspondingly, so that the height of the nacelle is unstable. Because the lifting rope has toughness, before a hanging flight test is carried out according to a specified flight track, the helicopter needs to adjust the flight height according to the flight speed and the bending degree of the rope so as to ensure that the test nacelle is positioned at a specified altitude, and the complexity of the test process is increased. Meanwhile, in the flying process, a tester opens a hatch of the helicopter to receive and release the hanging equipment, and the personal safety of the tester has hidden danger.
In order to avoid the above disadvantages of the lifting rope, the experimental nacelle is suspended by generally adopting a fixed support mode at present, but compared with the lifting rope, the fixed support cannot be adjusted, so that the adaptability is poor, different helicopters need to be matched with corresponding supports, and the cost is huge.
Therefore, it is desirable to provide a test chamber hanging device for a fuse low-altitude hangoff test.

Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
The traditional fuse low-altitude hanging test is that a test nacelle is hung on a helicopter by using a steel wire rope, and the helicopter is used for towing and flying. Because the lifting rope has certain toughness, when the helicopter drags and flies at a constant speed to the test chamber 1, the lifting rope is in a stable parabola shape; when the speed of the helicopter changes, the form of the lifting rope also changes correspondingly, so that the height of the nacelle is unstable. Because the lifting rope has toughness, before a hanging flight test is carried out according to a specified flight track, the helicopter needs to adjust the flight height according to the flight speed and the bending degree of the rope so as to ensure that the test nacelle is positioned at a specified altitude, and the complexity of the test process is increased. Meanwhile, in the flying process, a tester opens a hatch of the helicopter to receive and release the hanging equipment, and the personal safety of the tester has hidden danger.
In order to avoid the above disadvantages of the lifting rope, the experimental nacelle is suspended by generally adopting a fixed support mode at present, but compared with the lifting rope, the fixed support cannot be adjusted, so that the adaptability is poor, different helicopters need to be matched with corresponding supports, and the cost is huge.
