摘要
Abstract
The airliner family is a set of airliners that uses a common sub-system or components while meeting different performance or operation requirements. The airliner family can share a larger market, which is one of the key strategies for success in business. Due to the shared demand, the optimization for conceptual design of airliner family is different from that of traditional conceptual airliner design. An effective optimization method is studied for conceptual design of the airliner family. A short/medium haul airliner family is used as an example for demonstration of the method. The configurations of the airliner family are presented. A global analysis code is modified to evaluate the conceptual design. The optimization formulation for the conceptual design is presented in detail, including design variables, design constraints, and objectives. A self-adaptive evolution algorithm is used to solve the optimization problem. The results after optimization indicate that the specific design requirements for each aircraft are satisfied, and design objectives (direct operating costs) are reasonably compromised for the airliner family.关键词
