From the results of Chebyshev fit for a propeller serial across four quadrants, a Chebyshev representation of the four quadrant propeller properties is proposed for a deep submergence vehicle. The relation between J and J′ is clarified for the conditions across to four quadrants and its variation in ordinary and dynamic situations is further studied. The simulation models of DSV corresponding to four quadrant propeller work are given. The simulations show that the results are very colose to the existing practical data and, therefore, the correctness and effectiveness of above results are pvoved.
