Abstract:	With the objective of minimizing the number of aircraft used, this paper proposes an optimization model of aircraft loading schemes for multiple large equipment, under the condition of the constraints of the total weight limit, spatial limit, center of gravity balance and compartment floor loading limit. The initial feasible solution is obtained by random search algorithm, and the optimal solution is obtained by tabu search algorithm. The optimization problem of an air load of 15 large equipment with aviation compatibility is calculated. The results show that the average space utilization rate of the transport aircraft is 83.8%, and the average load utilization rate is 66.8%, both of which reach a high level on the basis of meeting the total weight limit, spatial limit, center of gravity balance and compartment floor loading limit. The main innovations are as follows: Firstly, a method is proposed to solve the problem of loading optimization of large equipment across different zones in the cargo hold of a transport aircraft; Secondly, all large equipment to be loaded is sorted into a sequence of equipment to be loaded as required to construct a feasible solution. Thirdly, the total length and total load capacity of the cargo hold of the transport aircraft are used as the basis for dividing the equipment sequence.
