Based on the model of aircraft carrier "Kitty Hawk", a study on the influence of resistance performance and main elements was carried out. A designer will find out the elements effecting the aircraft carrier designing through its coefficient of Lω/Bω and block coefficient. With the change of coefficient of Lω/Bω and block coefficient improved by the law, the resistances were calculated. The objective of the optimization is to minimum resistance, optimal rapidity, also give a consideration to stability and seakeeping performance, optimizing the main dimensions with the restrictions of flight deck width. The speed of the optimal ship has increased from 32 kn to 35 kn. Compared with the parent ship, the main dimensions of optimal ship decreased while have performance improvement. © (2013) Trans Tech Publications, Switzerland. Source

In this paper, we obtain the detailed and precise data of the resistance performance in shallow water for the win-skeg buoy tender in the different shallow-water conditions by the numerical stimulation of the resistance characteristic with the assistance of the commercial software FLUENT. Otherwise, the above obtained data are used to compare with the experimental results of the corresponding model in the towing resistance experiment. FLUENT is indeed competent and reliable for the calculation of the ship resistance. © (2013) Trans Tech Publications, Switzerland. Source

The research in the fundamental principle and iteration steps of the simulated annealing algorithm is carried out. It is brought in the scheme generation for the overall elements of the aircraft carrier design. Taking account of the stability, celerity, seakeeping, operational effectiveness and the cost of the aircraft carrier, the minimum objective function model is built up. Overall optimization of elements is achieved according to this model in FORTRAN language. The results show that the global optimal solution can be efficiently obtained by using simulated annealing algorithm, without any limitation of the initial points. After the optimization, the stability, celerity, seakeeping, operational effectiveness and the cost of the aircraft carrier are sufficiently improved. Source

This paper studies the overall elements of aircraft carrier at the stage of demonstration and preliminary design. Firstly, the estimation formula of the attributes is developed, which should be considered in preliminary design of ship. Secondly, the basic multi-objects optimize model is built up according to weighted vector obtained by lowest deviation method. Finally, optimization based on the simulated annealing algorithm is achieved. The computing system will find the most reasonable scheme of overall elements through the model after the designer determines the constraints of the principal dimensions and the number of carrier-based aircraft and the importance of each objects. © Springer-Verlag Berlin Heidelberg 2013.
