关于排水型两栖车辆水上航速的研究

Study on the Navigating Speed of the Displacement Amphibious Vehicle on Water

本文引入造船学的有关理论,从理论和实验基础上研究履带式排水型两栖车辆水上航行所遇到的阻力,以形状阻力和兴波阻力为主.高速航行时,兴波阻力上升为主要阻力成份,它是阻碍排水型两栖车辆水上航速提高的主要原因,由此文中提出了排水型两栖车辆水上实用极限速度问题.

This paper introduces conceptions concerning naval architecture. On the basis of theory and experiment, it studies the drag which the tracklaying displacement amphibious vehicle overcomes while navigating on water. The drag is classified as the form drag and the wave drag primely. When it sails at high speed, the wave drag becomes its main resistance. This is the prime cause that prevents the displacement amphibious vehicle from raising speed on water. Hence, a working limit speed problem of the displacement amphibious vehicle on water has been put forward in this paper.
