Numerical investigation on water-entry impact load of TMA based on CEL algorithm

Abstract This work presents comprehensive numerical research on the impact load of trans-medium aircraft (TMA) using coupled Eulerian-Lagrangian (CEL) method during a water-entry event. The velocity, angle, and attitude play significant role in characteristics trajectory. In this paper, model typical TMA structure is established to study with velocity 0, 2m/s, 4m/s, 6m/s, 8m/s, angle 90°, 80°, 70°, 60°, 50°, 50°. Subsequently, variation laws different are analyzed. results obtained from investigation can supply good reference structural design TMA.
