DEVELOPMENT OF MONTE-CARLO METHODS FOR SOLVING AERODYNAMICS PROBLEMS OF REENTRY SPACE VEHICLES
The most service time of aerospace vehicles is at high-altitude, in free molecular flow conditions and the experimental investigation for its moving in this condition is quite problematic. Significance of rarefied gas dynamic is explained in practical importance to solve a wide range of the problems connected with the present stage of space exploration, development of vacuum and nano technologies. The first application of statistical methods connected with direct simulation of rarefied gas flows and the direct simulation of Monte-Carlo (DSMC) method was appeared the most effective. The purpose of this work is to develop aerodynamic characteristics calculation method for space vehicles in high-speed rarefied gas flow. Calculation results of aerodynamic characteristics for reentry vehicle are presented. The results may be useful for perspective space vehicle project.
