Primary parameter calculation and optimization methods of traditional aircraft are not suitable for electric aircraft.A set of effective equations are developed for theoretically predicting the primary pa-rameters of electric aircraft by introducingtherelevant coefficient .Because particle swarm algorithm is based onthe evolvement technology of colony intelligence and has the advantages of facility to multi -ob-jectiveoptimization problems with complex restrictions ,mathematical model is built fordoing multi-objec-tive optimal design on electric aircraft .1) study of the particle swarm algorithm in the optimizationof air-craft primary parameters selecting battery weight as the single goal ofoptimization;2) study of the particle swarm algorithm in the optimizationof aircraft primary parameters selecting power unit weight , battery weight ,lift-drag ratio and range as multi-goals ofoptimization;3 ) flow chart of optimization of electric aircraft primary parameters .Studies show that:compared with the statistics ,the example results show good consistency .Thus the proposed methods of primary parameter calculation and optimization can be effec-tively applied to electric aircraft .
