Embodiment Construction
[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. Spatially relative terms such as "below", "beneath", "under", "lower", "above", "on", "higher", etc. are used to facilitate description to explain the relative The orientation of two elements means that these terms are intended to encompass different orientations of the device in addition to orientations other than those shown in the figures. In addition, for example, "one element is on / under another element" may mean that two elements are in direct contact, or that there are other elements between the two elements. In addition, terms such as "first", "second", etc. are also used to describe various elements, regions, sections, etc. and should not be taken as limitations. Similar terms refer to similar elements throughout the description.

The invention discloses a protection device for an umbilical cord type connector falling test. The protection device comprises a binding unit used for being bound on a rocket body, a slow descending unit fixedly connected with the binding unit, a pulling rope connected to the slow descending unit, and a locking structure arranged at the movable end of the pulling rope. The locking structure is used for being connected with a connector; the binding unit comprises a flexible binding tape and a fastener arranged on the flexible binding tape, wherein the flexible binding tape is bound to the circumferential position of the rocket body through the fastener; and the slow descending unit is used for adjusting the acting force with the traction rope to reduce the speed when the connector falls off. The invention further discloses a protection method for protecting the connector in the falling test process of the connector. According to the protection device and the protection method, effectiveprotection can be realized during the connector falling test, and the rocket launching success rate is improved.
Description
technical field [0001] The invention belongs to the technical field of rocket launching, and in particular relates to a protective device and a protective method for the drop-off test of an umbilical cord connector. Background technique [0002] At present, in the aerospace field, the umbilical cord connector products that have been put into use basically do not perform the connector drop-off test before the rocket launch, mainly because the connector product is easy to hit the launch frame under the restraint of the pipeline during the drop-off test. damage to the connector. There are also very few aerospace companies that conduct a drop-off test before the rocket is launched, but no protective equipment is added during the test. It is also easy to cause the connector to fall off and directly hit the launch pad, which will cause damage to the connector. In this case, a new connector needs to be replaced when the rocket is launched, which makes this test meaningless, that i...
