电池供电的多旋翼飞机的低成本、简单性和易用性使其在商业、工业、农业和军事应用中得到采用。然而，这些飞机的有效载荷有限，续航力和航程都比燃料动力的传统飞机短。为了扩展这些关键性能指标，开发了一种结构电池，其使用市售电池单元作为重量关键应用的承载和电源元件。圆柱形结构电池在三点弯曲中进行测试，发现其刚度是没有电池加强件的结构的四倍，屈服强度是没有电池加强件的结构的两倍。四轴飞行器的模拟，重新设计与拟议的圆柱形结构电池，展示了41%的悬停时间。
The low cost, simplicity, and easy use of battery‐powered multirotor aircraft has led to their adoption in commercial, industrial, agricultural, and military applications. These aircraft, however, have limited payloads and shorter endurance and range than fuel‐powered conventional aircraft. To extend these key performance metrics, a structural battery is developed that uses commercially available battery cells as load bearing and power source elements for weight critical applications. The cylindrical structural battery is tested in three‐point bending and is found to have four times higher stiffness and two times higher yield strength than the structure without battery reinforcement. Simulations of a quadcopter, redesigned with the proposed cylindrical structural batteries, demonstrate 41% longer hover time.
