摘要
结合现代民用飞机绿色环保设计理念和对经济性的追求,减重是飞机设计中重点考虑因素。如何平衡民用飞机载水量与供水量的关系,对于降低民用飞机水废水系统运营载重,提高航线运营经济性至关重要。基于对航线用水统计数据的研究,给出航线运营所需水量计算技术;根据我国航线飞行时长分布特点,提出基于航线实际运营时间和载客人数为需求、为系统设定的分档加水设计技术,并对分档加水设计技术进行水位功能验证。结果表明:与同类机型数据对比,本文给出的航线需求水量计算技术是有效的;分档加水设计技术能够有效地降低系统在航线运营过程中的运营重量,提升民用飞机水废水系统的运营经济性。
Based on the green design concept of environmental protection and the pursuit of economy for civil air⁃craft,the weight loss is a key consideration factor in aircraft design.How to balance the relationship of water carrying capacity and water supplying capacity of civil aircraft is essential to reduce the operation carrying capacity of civil aircraft water and waste system,and improve the operation economy of flight route.On the basis of the re⁃search of route water consumption statistics,the calculation technology of water demand for route operation is given.According to the distribution characteristic of the flight hour in our country,the subsection water fill design technology based on the flight time and attendant number is proposed,and its water level function is verified.The results show that,in comparison with the data of other aircraft types,the water calculation technology for flight route requirement given in this paper is effective.The subsection water fill technology can reduce the operation weight of water and waste system in route operation effectively,and improve the operation economy of the civil aircraft water and waste system.
