摘要对电池驱动飞行器的续航能力进行了实验研究。在这项研究中，一架无线电控制的模型飞机在风洞中“飞行”。各种锂离子电池被用来为模型供电。在每次运行期间记录电池电特性以评估电池放电行为。基于电池特性的理论估计产生的耐久性估计值在实验测量值的3%以内。电池的放电特性被认为是耐久性估计的最大不确定性来源。
Abstract An experimental investigation is presented to validate endurance estimates for a battery powered flight vehicle. In this study a radio controlled model aircraft was ‘flown’ inside a wind tunnel. Various Lithium Ion batteries were used to power the model. Battery electrical characteristics were recorded during each run to assess battery discharge behaviour. Theoretical estimates based upon battery characteristics yielded endurance estimates within 3% of that measured experimentally. The discharge characteristics of the batteries were found to be the largest source of uncertainty for endurance estimates.
