Cross Parachute Analysis with
Parallel Computing on the CRAY T3E-1200

CDT David McCourtney, USMA

Principal Investigator:
Professor Tayfun E. Tezduyar, T*AFSM

This project is part of a greater research effort by the T*AFSM on airdrop systems. Our research on airdrop systems involves extensive collaborations with US Army Natick Soldier Center (NSC) and NASA Johnson Space Center. The specifications of the cross parachute were provided by our collaborators at NSC. CDT McCourtney's project work included mesh generation and parallel computations using the stabilized finite element methods and software developed by the T*AFSM. In this project, CDT McCourtney was helped by Dr. Andrew Johnson, at that time a research associate supervised by Tezduyar. Figure 1 shows the finite element mesh. Figure 2 shows the computed flow field at an instant.
