Research of thermal stress analysis on fuze

This paper describes that in high-speed flight of the projectile, temperature of fuze changes due to aerodynamic heating caused by the projectile surface layer, thus likely to impact fuze mechanical structure and internal circuit performance, even worse it can affect work of the fuze. So this paper studies the projectile surface aero-dynamic with the Supersonic flight of projectile based on Fluent software, then it can get the displacement of fuze component which caused by thermal stress using transient thermal analysis based on Ansys software. Therefore it can provide effective technical support for the design of fuze.
