An Overview of the Development of a Vortex Based Inflation Code for Parachute Simulation (VIPAR)

摘要: Sandia National Laboratories has undertaken an ambitious, multiyear effort to greatly improve our parachute system modeling and analysis capabilities. The impetus for this is twofold. First, extending the stockpile lifetime raises serious questions regarding ability of parachutes meet their requirements in future due material aging. These aging cannot currently be answered using available tools techniques which are based upon experience expert staff full-scale flight tests are, therefore, not predictive. Second, atrophy technology base loss experienced eroded respond any problems with stockpiled or rapidly design a new on alone. To assure in-house capability technical oversight nuclear weapon parachutes, must move from present empirically approach computationally based, predictive methodology. This paper discusses current status code development experimental validation activities. Significant milestones that have been achieved those coming up next year discussed.
