为解决飞艇使用常规化石燃料引起环境污染和携带充足燃油影响有效载荷比,而利用能量分散、易受光照时间影响的单一太阳能作为飞艇的能源存在利用率低和需携带足够储能装置存在的问题和不足,本文针对不同高度范围、留空时间各异、执行不同任务的各类飞艇,提出适合其需求的多能源系统方案,引出能量平衡关系式,应用功效函数法确立最优化模型,分别得出成本与电能、效率最优化关系式,由其可合理配置微型风力发电机数量、高效薄膜太阳能电池面积及化石燃料携带量,使产生的电能最多、效率最高,成本最低,飞艇能源系统达到最佳状态,保证飞艇全系统安全可靠工作,具有一定意义,给出功效函数法的评价机制以校验优化模型。
To solve problems and deficiencies of airship energy, these are using conventional fossil fuels which cause environment pollution, carrying numerous fuels which effect payload ratio, applying single solar whose energy is dispersive and which is susceptible to influence of time and low utilization rate and taking along sufficient storage device. Aiming at different height ranges, diverse time in the air, performing various tasks, solutions of multiple energy system for their needs are proposed. At the same time, energy balance equation is obtained, optimization models are established by efficacy coefficient methodevaluation function law and relationships of best optimization are acquired between costs and energy or efficiency. So the number of micro-wind turbines, the area of efficient flexible membrane solar cell and carrying capacity of fossil fuels are reasonably deployed, which generate the most power, highest efficiency and lowest cost. These that enable energy system to achieve optimal state and ensure safe and reliable operation of airship have a significance. The paper also gives the evaluation mechanism of efficacy coefficient method to verify the efficacy of optimization models.
