AI Technical Summary

Technical Problem

Traditional life-saving radios cannot be turned off after ejection from a rocket ejection seat, which exposes the pilot's position when ejecting in enemy-occupied territory, hindering rescue efforts.

Method used

A life-saving radio activation mode switching device was designed. Through the combination of a sliding plate and a fixed-force connecting rope, the device can switch between automatic activation in automatic mode and shutdown in manual mode. The irregular hole and steel ball on the sliding plate control the channel of the fixed-force connecting rope, and the pilot can select the activation mode as needed.

Benefits of technology

It enables automatic activation of the life-saving radio when needed and manual deactivation when not needed, ensuring the pilot's safety in dangerous situations. It is applicable to various types of rocket ejection seats, is easy to operate, and has good applicability.

Abstract

The application discloses a lifesaving radio starting mode conversion device, which comprises a sliding sheet, a constant force connecting rope, a sliding groove sheet and a gasket layer which are connected together and arranged on both sides of the sliding sheet, a through hole on the sliding groove sheet and a through hole on the gasket layer form a channel for the constant force connecting rope to pass through, the sliding sheet can slide a distance relative to the sliding groove sheet and the gasket layer when the sliding sheet is pushed and pulled, one end of the constant force connecting rope is connected with a lifesaving radio starting pull pin, and the other end of the constant force connecting rope is connected with a seat, the constant force connecting rope is provided with a safety device and a steel ball, the sliding of the sliding sheet makes different parts of the special-shaped hole appear in the channel for the constant force connecting rope to pass through, so that the steel ball can pass through the channel or be blocked by the special-shaped hole, and the gasket layer is connected with a lifesaving bag. The application can be applied to lifesaving bags of multiple models of rocket ejection seats, has good applicability and is simple to operate.
