Emergency window sealing rubber strip jettisoning device and method for helicopter

Abstract

The invention belongs to the technical field of helicopter structure design, and particularly relates to an emergency window sealing rubber strip jettisoning device and method for a helicopter. The device comprises a mounting rubber strip (2), two jettisoning rubber strips (3), a jettisoning handle (1) and a bolt assembly (4). When the helicopter is in an emergency, the personnel in the helicopter can use the emergency window sealing rubber strip jettisoning device to complete emergency window jettisoning, and emergency escape is achieved. Compared with a traditional helicopter emergency window jettisoning device, in the aspect of structure, the structure of a jettisoning mechanism is simplified, the weight of the jettisoning mechanism is reduced, and the problem of jettisoning clamping stagnation is solved; in the aspects of operation and use, the jettisoning device is easy to operate, operation steps during jettisoning are reduced, the jettisoning force is reduced, the jettisoning time is shortened, and precious time can be saved for emergency escape; and in the aspect of maintenance and guarantee, the jettisoning device is convenient to maintain and repair, and is convenient and simple to disassemble and assemble.

Description

technical field [0001] The invention belongs to the technical field of helicopter structure design, and in particular relates to a device and method for throwing emergency window sealant strips for helicopters. Background technique [0002] The emergency window belongs to the emergency escape system of the helicopter. When the helicopter is in a crisis, the crew can throw the emergency window to realize emergency escape. The existing helicopter emergency window throwing devices are explosive and mechanical. [0003] The structure of the explosive throwing device is complex, relying on multiple detonators to complete the multi-point blasting of the emergency window, and finally complete the throwing of the emergency window. However, as a fire control product, the explosive throwing device is difficult to be applied to civilian aircraft, and there are certain safety hazards in use. The actual application is less and has great limitations. Since the emergency window needs to b...

AI Technical Summary

Problems solved by technology

In the mechanical ejection device, the connecting rod ejection form is the most common, but its structure is complex, the weight is heavy, and the ejection operation process is cumbersome. Emergency ejection will consume more time and delay the best time to escape.

The latches and connecting rods of the throwing mechanism are arranged on the frame of the window frame. When the frame of the window frame is deformed, problems such as latch jamming and connecting rod deformation may occur, resulting in excessive force when throwing, making it difficult to throw, and even the emergency window stuck on the window. Cannot be thrown in the box
