太阳能/氢能长航时无人机重量能量耦合分析

提出一种太阳能/氢能长航时无人机重量能量耦合分析方法,即在太阳能/氢能长航时无人机的概念设计阶段,通过在质量与能量迭代求解过程中嵌入与能量相关的参数的求解,从而计算出相应总体参数下的质量和能量情况,得到无人机基本性能指标的估算。通过重量能量耦合分析方法,无人机的质量迭代计算得到收敛、能量结余系数和有效载荷系数2个重要设计指标在求解过程中获得收敛。由于提出的分析方法可完成无人机重量估算,及重要设计指标的估算,因而对于太阳能/氢能长航时无人机的概念设计具有重要意义。

WEIGHT ENERGY COUPLING ANALYSIS FOR SOLAR HYDROGEN LONG-ENDURANCE UAV

This paper presents a method for the analysis of the mass energy coupling of solar hydrogen long-endurance UAV,that is,in the conceptual design stage of solar hydrogen long-endurance UAV by embedding solving energy-related parameters in the process of mass and energy iterative solution,to calculate the mass and energy under the corresponding overall parameters and giving estimate of basic performance indicators of UAV. By using the mass energy coupling analysis method proposed in this paper,the mass iteration gets convergent and the two important design indexes of energy surplus coefficient and payload coefficient are obtained in the example. As the analysis method proposed in this paper can complete the estimation of UAV mass and the estimation of important design indexes,it is of great significance for the conceptual design of solar hydrogen long-endurance UAV.
