Abstract

This paper based on the ALE algorithm, the helicopter with emergency floating system load characteristics during ditching are numerically simulated and analyzed. Provide support for the design of emergency floating system, gasbag installation point and personnel evacuation channel. First of all the ditching model of the helicopter and the floats is established, and the accuracy of the simulation model and the calculation method is verified by comparing the results of the scale model and the physical testing, verified the accuracy and effectiveness of the simulation model, modeling method and calculation method. Then by using this method establish the full-size model. Based on this method, the influence of different roll angles, horizontal velocities and vertical velocities on the helicopter impact load during ditching is studied. This paper provides support for the design of emergency floating system, gasbag installation point and personnel evacuation channel. It not only overcomes the difficulty that the full-size prototype cannot carry out physical experiments, but also can effectively shorten the development cycle and save development funds.
