Parachute Computation in
the Far Wake of a Wing
CDT Kyle Brennan, USMA
Professor Tayfun E. Tezduyar,
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
and NASA Johnson Space Center. The T*AFSM is working on developing the
methods and tools needed to simulate the effect of unsteady wake flow on
a paratrooper jumping out of a trailing aircraft and crossing the wake
of the leading aircraft. CDT Brennan worked on parallel computation of
the effect of an unsteady wake flow generated by a wing on a
paratrooper. He generated the finite element mesh for the parachute, and
carried out the simulation for three different lateral locations of the
paratrooper at the wake of the Wing. In this project, CDT Brennan was helped by
Mr. Yasuo Osawa, at that time a PhD student supevised by Tezduyar.

mesh. Figure 2 shows the computed flow field at an instant.
