J.-H. Borchard,F. Dierßen,J. Kotlarski,L. A. Kahrs,T. Ortmaiertative efficiency is the ratio of the open water propulsive efficiency to the efficiency of the propulsor when operating in the wake. The Quasi Propulsive Coefficient (QPC) is the ratio of useful power to the power delivered to the propeller. Submarines are often propelled by a large optimum diamete

F. Simroth,H. F. Ding,A. Kecskeméthyn optimum value of the .. to minimise resistance, depending on the hull form. The aft body shape can be characterised by the half tail cone angle, which defines its fullness. The primary aim of the design of the aft body is to avoid flow separation, and ensure good flow into the propulsor. Appendage

A. Kłodowskiare discussed. The aft control surfaces may include fixed and movable surfaces, with the fixed surfaces increasing stability, and the movable surfaces used to change trim, and hence to make large depth changes, and to turn the submarine. Different aft control surface configurations include: crucifor
