This project is part of a research effort by the T*AFSM in collaboration with US Army Natick Soldier Center. When a cargo aircraft with relatively new design is put into operation, the aerodynamic interaction between the aircraft and a paratrooper or a payload separating from that aircraft becomes a very relevant issue in terms of successful and effective airdrop operation. The goal in this project is to simulate such aerodynamic interactions.

Figure 1: Here we see how the model of the paratrooper was improved to better reflect the actual conditions.

Figure 2: In this picture we see the aerodynamic simulation of a payload as it exits from the cargo door of the aircraft.
