面向有效载荷质量的平流层飞艇设计参数优化
Design parameters optimization for stratospheric airship payload mass
摘要
Abstract
The maximal payload capacity is an important merit index for stratospheric airship conceptual designs, which is associates with a number of factors. Firstly, the performance estimation models for subsystems were provided. Based on these models, a maximal payload capacity optimization model with considering the buoyant weight balance, pushing resistance balance, energy balance, the material strength constraints etc was proposed. And an example calcultion was carried out based on chaotic particle swarm algorithm. The results show that: the goals such as minimum resistance or mass can't be a good response to airships' task. In addition, the design of stratospheric airship is a solution process with subsystems tightly coupled and mutual constrained. Through design parameters optimization with constraints such as resistance, buoyancy, energy, materials, etc are considered, the capability of airship payload increases by 50%.关键词
