To develop the decelerating and rigging potential performances of cruciform parachute during to its relatively large stand-off with lower cost production in precision aerial delivery operations, the fluid structure interaction behaviours of steerable cruciform parachute is studied. The concept of suspension lines control of cruciform parachute is firstly proposed. Based on the multi-material Arbitrary Lagrange-Euler method, the coupling dynamic model between a viscous incompressible fluid and a flexible large deformation structure of the cruciform parachute is solved. The inflation performance of a cruciform parachute under different steerable conditions is analysed. The decelerating parameters of the parachute, including drag area, and opening loads are obtained from FSI simulation. Meanwhile, the evolution of the three-dimensional shape of the cruciform parachute inflation is predicted.
