Abstract
The invention discloses a method for cutting a cable of an overwater floating recorder, belongs to the field of an airplane design, and relates to a flight data record major. The overwater floating recorder is characterized by comprising a cable pressing block, an initiation control cabinet and a plane wave generator, wherein the cable pressing block is in a U shape, a to-be-cut cable is fixed on a mounting rack by a U-shaped slot in the cable pressing block, the plane wave generator is placed below the to-be-cut cable, and the initiation control cabinet provides a large instantaneous current to initiate the plane wave generator after meeting trigger conditions, so as to generate a shearing force to cut off the cable. The method provided by the invention has the beneficial effects that the problems caused by adopting a pulling out connector can be solved by using a way of physically cutting off the cable, and the problems of mistakenly cutting off or maintaining the cable can be prevented.
Description
Technical field
The invention belongs to airplane design field, relate to flight parameter record specialty.
Background technology
In flight parameter record specialty, the application of floating on water surface logger has solved after aircraft accident waterborne, and logger is difficult to the problem of search.After aircraft has an accident on the water, the butterfly logger with floating on water surface function can separate with body automatically, swims on the water surface and transmitted radio signal, searchable personnel's searching.
After floating on water surface logger separates with the set bolt of body, also be connected with the cable on machine, cable is a kind of flexible structure, how to ensure cable moment, reliable separation on floating on water surface logger and machine, is that can floating on water surface logger launch a key point leaving body.Current existing cable machinery separates the designs that adopt pulling-out connector more, as the guided missile of aircraft and ejector seat.Because floating on water surface logger will launch from the upper surface of aircraft, adopt pulling-out connector separate mode to have following problem:
A) on machine, cable connector need to be fixed on installing rack, need to be arranged in lower surface at the connector of logger, opens while safeguarding lid connector invisible, on-board maintenance difficulty;
B) because breakaway connector connector size is larger, need to increase the gap of installing rack and logger, and then cause installing rack size to increase, weight increases, and does not meet space, the weight indicator requirement of aircraft to system.
Summary of the invention
Technical problem to be solved by this invention is: a kind of simple, reliable, effective cable cutter blanking method of floating on water surface logger is provided.
Technical scheme of the present invention is: a kind of floating on water surface logger cable cutter blanking method, it is characterized in that, comprise cable compact heap, initiation control box and plane wave generator, wherein, cable compact heap is " U " type, to be sheared cable by the U-shaped groove of cable compact heap is fixed on installing rack, plane wave generator is placed on the below that is sheared cable, initiation control box is after meeting trigger condition, a transient high-current is provided, ignite plane wave generator, produce a shearing force by cable cutting.
Beneficial effect of the present invention: the mode that uses this physics to shear cable has solved the problem that adopts breakaway connector connector to bring, and the problem that can avoid cable to cut off by mistake and safeguard.
