Abstract

The area of the flight deck on the aircraft carrier is limited. To improve the utilization rate of the flight deck and increase the amount of aircraft, the layout of aircraft is discussed. The docking relationship between envelope graphs of carrier aircraft and the determination method of their internal position in deck contour graphs are studied. The above-mentioned problem belongs to the calculation of critical polygons in two-dimensional irregular layout problem. The position of the aircraft is determined by overlapping the centre of gravity of the aircraft with the lowest point on the critical polygon, which is according to the proposed principle of the “lowest centre of gravity . The principle and optimization method of the improved simulated annealing (SA) method are studied. The method is studied according to the contact condition between the envelope figures of aircraft, which is used to determine the position of the envelope figure in the deck contour figure. The improved SA method is used to optimize the layout of aircraft graphics in a deck graphic. The simulations show that the improved SA method is better compared with recursive method. The utilization of the deck area is increased by 7.7%.
