AI Technical Summary

Technical Problem

Existing helmet separation schemes suffer from problems such as complex structure, high cost, heavy weight, large impact load, and complex timing control, making it difficult to meet the requirements of rapid and safe separation for hypersonic missiles.

Method used

A direct-push hood separation method is adopted. Through aerodynamic shape and structural optimization design, the hood is kept in a neutral and stable state during separation. The axial separation speed is provided by separation actuators of the same specifications. The minimum separation speed and the number of actuators are determined by combining unsteady separation simulation analysis to achieve safe separation of the hood.

Benefits of technology

The weight of the hood and the impact of separation were reduced, the structure of the separation system was simplified, the research and development and production costs were reduced, and the reliability and safety of the separation system were improved.

Abstract

This invention provides a direct-thrust missile hood separation method and structure, primarily addressing the problems of added counterweights and complex timing control in existing hood separation schemes. In this invention, the lateral separation velocity is provided by the lateral aerodynamic force generated during hood separation by adjusting the missile's attitude. While ensuring load-bearing and heat protection requirements, the same specifications of separation actuators are used, resulting in a simpler separation structure. The hood separation scheme only requires the separation actuators to provide the specified axial separation velocity, reducing the synchronicity and speed requirements of each actuator during operation, lowering the timing control requirements of the system, and improving the reliability of the separation system.
