Abstract:-  — The knowledge of flow behavior and associated aerodynamic characteristics are important in the design and analysis of a multi-stage launch vehicle. A typical launch vehicle in flight passes through denser layers of atmosphere covering both subsonic and supersonic Mach numbers. Aerodynamic coefficients are important inputs for trajectory simulation, performance analysis and control system design of a launch vehicle. A multi-stage launch vehicle with strapons is a complex configuration to study the flow behavior over it. Generally extensive wind tunnel testing is done to understand the flow characteristics of such a configuration. With the current popularity of Computation Fluid Dynamics (CFD) as a powerful design tool, it is appropriate to make use of its technology to understand the complex flow behavior over a multi-stage launch vehicle with strapons. Most present day launch vehicles have either solid or liquid strapons to meet the mission requirements
