基于全寿命周期费用的电动飞机外形参数多学科优化设计
Multidisciplinary optimization design of electric aircraft geometric parameters based on the entire life cycle cost
摘要
Abstract
To reduce the development costs of electric aircraft,a multidisciplinary optimization design approach was investigated based on the entire life cycle.By analyzing the composition of the entire life cycle costs for electric aircraft,an entire life cycle cost estimation model was developed.The research established multidisciplinary analysis models encompassing aerodynamics,flight performance,mass,and economic factors.With the optimization objective of minimizing life entire cycle costs,a comprehensive multidisciplinary optimization design method for electric aircraft was proposed.Taking a four-seat electric aircraft as a case,the parallel subspace optimization algorithm was employed to identify the optimal solution,resulting in an optimized overall design scheme that validates the method's effectiveness.This method can be applied to electric aircraft conceptual design,providing technical support for electric aircraft development.关键词
