Multidisciplinary optimization design of electric aircraft geometric parameters based on the entire life cycle cost
为了降低电动飞机的研制成本,研究了基于全寿命周期的电动飞机多学科优化设计。通过研究电动飞机全寿命周期费用的组成,得到电动飞机的全寿命周期成本估算模型。建立电动飞机气动、飞行性能、质量和经济性学科分析模型,以电动飞机全寿命周期费用最低为优化目标,提出一套基于全寿命周期费用的轻型电动飞机多学科设计优化方法。以某型四座电动飞机为例,利用并行子空间优化算法对模型进行优化找到了最优解,从而得到最优的总体设计方案,验证了方法的有效性。本方法可应用于电动飞机概念设计,为电动飞机研发提供技术支持。
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.
