Matching design for payload and range of civil aircraft family

There has been a pattern transform from single model to family with multiple models for the civil aircraft-developing concept. According to the strategies of modularization and generality, the aircraft family design method was developed. The design principle of the main parameters and the economic description method for the aircraft family were presented. Then the matching design model for payload and range of the aircraft family was established. The impact of the matching relationship of the payload and the range acting on the economy of the aircraft family was analyzed, too. With application of Pareto multi-objective genetic algorithm, the matching design for payload and range of a civil aircraft family was accomplished. The parameter comparison of different design schemes was carried out, and the results are satisfactory.
