摘要
为了选择经济高效的旅客机环境控制系统,对现役各种旅客机采用的环境控制系统方案进行了优化设计和比较,分别建立了二轮简单式低压除水系统、三轮升压式高压除水系统和四轮升压式高压除水系统(又称冷凝循环制冷系统)的优化设计数学模型,以起飞燃油质量代偿损失为目标函数,采用广义乘子法结合单纯形加速法求解,优化结果可作为设计研究旅客机环境控制系统的理论依据。
In order to choose the most economical and efficient airliner environmental control system, several types of air cooling systems for the modern airliners were optimized and compared. The optimized mathematical models of two wheels system with low pressure water separation, three wheels system with high pressure water separation and four wheels system with high pressure water separation were established respectively. The fuel oil loss for airliner environmental control system is taken as the objective function. Generalized multiplier combined with simplex method is used to seek the optimum solution. The optimized results can be used as the theoretic foundation for the design and research of airliner environment control system.
