In order to develop faster, lighter, more maneuverable, and more accurate defense interceptors, jet interaction (JI) aerodynamic controls are being pursued to achieve highly effective control authority across large portions of the battlespace. The reliable use of JI to control a kill vehicle (KV)… More

The use of multidisciplinary analysis (MDA) techniques for complex fluid/structure interaction phenomena is increasing as proven numerical and visualization algorithms and high performance computing (HPC) platforms become more prevalent. Parallel solution methodologies and networked computing… More

The challenges of designing, developing, and fielding man-rated propulsion systems continue to increase as NASA's Vision for Space Exploration Program moves beyond the Space Shuttle and RSRM. The number and type of different propulsion elements required are significant, and predicting internal… More

The challenges of designing, developing, and fielding man-rated propulsion systems continue to increase as NASA's mission moves forward with evolving solid propulsion requirements. Recent developments in simulating solid rocket motor environments include Lagrangian particle tracking, particle… More

The goals of reducing total cost and increasing reliability and safety of access to space continue to be top priorities for NASA. The most immediate propulsion launch challenge involves increasing lift weight from 70 to 130 metric tons by developing the heavy lift Space Launch System (SLS). Solid… More
