Aerodynamic performance enhancement of missile using numerical techniques

The objective of the paper is to conduct aerodynamic analysis on V-2 missile. The V-2 missile was the world's first ballistic missile and the first object to go into space. It is a long-range liquid propelled missile. It uses aerodynamic surfaces such as wings, fins, control surfaces and fuselage to deliver the lateral maneuverability. This is accomplished by deflecting the control surfaces through the actuation mechanism and thereby modifying the equilibrium forces and producing various moments. The V-2 missile was 14 meters long and weighed 12,700-13,200 kg at launching. It produces about 266 KN of thrust. ANSYS modeler is used to model the V-2 missile, and the flow around the missile body has been evaluated using the ANSYS workbench. This paper carried out simulations for varying angles of attack and Mach numbers until the stall was observed. Effects due to density, pressure coefficient, temperature and Mach number on the missile is noted in order to undergo detailed flow analysis.
