摘　　要：为验证新型潜伏式无人船型在水面高速-半潜多种航态之间连续变换的航行原理,建造了约1t的自航模型,并基于自航模型性能测试系统对不同排水量、不同航速、不同加速条件和不同压载流道进排流条件下的变航态航行特性开展了试验研究.结果表明：船型及排水量对轴功率的影响主要集中在弗劳德数（Fr）为0.5～1.0的航速区间;加速和减速方式是主导该平台不依赖吹除装置、自动进排水完成航态变换的重要因素;匀速运动的航速与航态保持能力直接相关,当体积弗劳德数大于1时压载水可完全排出.A self-propulsion model that weighs about 1ton was built to testify the navigation principles of a newly designed latent high speed craft（LHSC）which could switch between surface and semi-submersible states.The performance tests on the model were conducted in the measurement system to clarify the effects of displacement,velocity,acceleration and ballast inlet/outlet conditions on the navigation mode conversion.It turns out that the shaft power is mainly affected by the new hull design and displacement when 0.5Fr1.0.The automatic inflow and outflow function of the ballast that independent of blow device is restricted by manners of acceleration and deceleration.The velocity of uniform motion is directly related to the capability to maintain current state and the ballast will be drained empty when volume Froude number Fr1.
