摘要:为了提升垂起固定翼无人机垂直机动时间,在简化油电混合动力系统研究与应用难度的同时提高油电混合动力垂起固定翼无人机能量利用率与动力冗余度,提出了一种油电混合动力垂起无人机动力系统拓扑结构方案。基于此拓扑结构选择与开发适配于起飞重量为15-20kg的垂起固定翼无人机动力系统软硬件,以此搭建了油电混合动力垂起无人机动力系统一体化验证平台,该验证平台能够在地面模拟油电混合动力垂起无人机不同工况与工作模式,同时具有较强的人机交互性,能够实现对动力系统不同工况下的典型输出参数采集。基于此验证平台,设计了动力系统稳态特性与动态特性试验方案,采用试验建模法建立了动力系统稳态与动态数学仿真模型,通过仿真与实物对比试验分析法,验证试验方案可行性与模型准确性。动力系统配装垂起无人机完成飞行试验,全系统工作正常,验证了实际工况下动力系统的可靠性。
Abstract:A new topology was developed for the fuel-electric hybrid VTOL UAV power system in order to improve the vertical flight duration of the VTOL UAV, reduce the research and application complexity of the hybrid power system, increase the VTOL UAV"s energy usage ratio, and increase its power redundancy. The software and hardware that are appropriate for the hybrid power system of the VTOL UAV with a take-off weight of 15 to 20kg were chosen and developed based on this topology. Additionally, a framework for the integrated verification platform of the hybrid power system was constructed, which can simulate various working conditions and operational modes on the ground for a VTOL UAV powered by fuel-electric hybrid power system. With high human-computer interaction, this platform can collect the power system"s output parameters under various working conditions. Based on this platform, the testing schemes for the steady-state characteristics and dynamic characteristics of the power system were designed, steady-state and dynamic simulation models of the power system were established by using the experimental modeling method. By comparing simulated and experimental results, it was able to confirm the viability of the test and the model"s correctness. The power system was equipped with a VTOL UAV to complete the flight test, and the whole system worked normally, which verified the reliability of the power system under actual working conditions.
