- The high cost of the reliability test for water-entry process of air-launched vehicle prompts the numerical simulation method which has become a mainstream in the process of equipment development. In this paper, the author integrated the simulation results of vehicle failure mechanism with the calculation of mission reliability of water-entry vehicle through the model research of water-entry process of air-launched vehicle under the condition of complex wave, and structured water-entry vehicle reliability model under complex wave condition, based on failure mechanism simulation environment. Furthermore, based on the basic flow field data obtained from CFD simulation, the author gained the movement parameters models on Attitude Angle, Angular Velocity and Centroid Displacement of the water-entry process of air-launched vehicle through the least squares fitting, which provides the basic input data for the reliability analysis of the vehicle water-entry process. In the end, the author fitted simulation results into the reliability model, and presented the reliability analysis result according to the fitting results of Attitude Angle, Angular Velocity and Centroid Displacement.
