Abstract:

With the development of operational requirements and information technology, all kinds of information projectiles with the functions such as reconnaissance and positioning, precision attack, blockade and jamming have been born. The exertion of their effectiveness usually requires that the missile borne functional devices/components, missile body structure and materials can resist various high overload effects. The anti-high overload technology has become one of the main bottleneck technologies restricting the rapid development of shell informatization and intelligence. This paper combs the development process of the anti-high overload problem of information projectiles, and expounds its essential connotation. The key anti-high overload technologies such as overload environment modeling and measurement, anti-overload structure and materials, anti-high overload test are summarized. This paper puts forward the anti-high overload design idea with functional protection as the core goal, defines the anti-high overload design process of information projectiles. The anti-high overload method of “body strength reinforcement, support deformation and energy absorption, structural member damage transfer and intersection of cutting-edge technologies” proposed in this paper has achieved good results in engineering practice, and provides some reference for the anti-high overload design of information projectiles, rockets and missiles with high overload characteristics.

Key words: information projectile, anti-high overload, key technologies, functional protection, design method
