Rapidity Optimization of the Aircraft Carrier Based on the Minimum Resistance

On the basis of the model of the aircraft carrier "Kitty Hawk", the designer will obtain different models through parody transformation to change its aspect ratio(Lω/Bω), block coefficient(Cb) and displacement(∆) and calculate the resistance of different models. With the principle of the optimal speed, taking an overall consideration of initial stability, seakeeping performance and the restrictions of flight deck and hangar width of the aircraft carrier, we get a new ship form and the corresponding speed. Compared the results with the parent ship, the speed of the optimized ship has increased from 32 kn to 35 kn. The conclusion is that the rapidity of the new ship has been optimized.
