摘要
针对气象条件复杂的对流层对飞艇动力系统的较高要求,基于统计分析得到对流层飞艇平台动力系统功率配置准则,完成某小型飞艇动力系统的初步选型;通过工程算法对航空活塞发动机和螺旋桨的性能进行分析、预测,计算螺旋桨与飞艇平台的驱动力平衡、螺旋桨与发动机的驱动力矩平衡,经过耦合力平衡与耦合力矩平衡完成动力系统与飞艇平台性能匹配的分析、评估。此工程方法为动力系统与飞艇平台的功率匹配分析乃至飞艇平台的飞行性能预测提供了有效方案。
To meet the high requirements of troposphere on the power system of airships for the relatively complex working environment and meteorological conditions,this paper summarized basic principles of troposphere airship platform power allocation based on statistical analysis,and completed the preliminary power-plant option of a small airship;analyzed and predicted the performance of the selected aerial piston engine and fixed-pitch propeller by using the engineering algorithm mentioned;calculated and analyzed the balance of driving force between airship platform and engine and the balance of driving torque between engine and propeller;and finally analyzed and evaluated the performance matching of the selected power system and the airship mentioned through coupling the balance of driving force and driving torque using the method introduced in this paper.The engineering approach presented in this paper proves to be an effective solution to the matching analysis of power system and airship platform and even flying performance forecast of airship platform.
