CFD SIMULATION AND FEA ANALYSIS OF A BALLISTIC MISSILE

Abstract

The ballistic missile model analysed in this paper presents a stringer type fuselage having 10 control surfaces, 8 directional surfaces to execute turns and 2 to execute manoeuvers for changing the angle of attack, but also 4 direction stabilisers. In this paper a CFD simulation was carried out on ballistic missile with a new structure for determining the flight performance and the aerodynamic configuration. It was also performed a finite element analysis of the ballistic missile and the results obtained allowed to precisely determine the areas where the stress is greatest and where is necessary to provide several measures to increase the structure’s rigidity, to protect it from temperature and pressure.
