摘要

风机是超压气球高度控制系统的核心设备之一，高性能的风机对超压气球的高度控制能力和飞行安全具有重要影响。本文提出了一种用于超压气球的混流式 MIX-140 风机。研究了超压气球在不同飞行高度下风扇工作特性的变化。首先，通过数值模拟获得了风机在地面的性能，并与原型机的测量数据进行了比较，以验证模拟分析的准确性。在此基础上，通过数值模拟研究了大气压力、温度和风扇转速的变化对风扇性能的影响。此外，还将 MIX-140 风机与现有风机进行了比较，并研究了单位时间充气量比和单位功率充气量比这两个参数在不同海拔高度下的变化情况。最后，通过实际测试研究了风扇在不同高海拔环境下运行特性的变化。结果表明，海拔高度的变化会导致风扇性能发生显著变化，大气压力、温度和风扇转速的变化也会影响风扇的工作特性。与现有风扇相比，MIX-140 风扇在 16-20 千米的海拔高度上，单位时间的充气量平均增加了 295.8%，单位功率的充气量平均增加了 14.6%。这种拟议的超压气球风扇的性能变化特征和测试方法可为超压气球控制系统的设计提供基础和参考。

Analysis and Testing of Variable Height Operating Characteristics of Super-Pressure Balloon Airbag Fan

A fan is part of the core equipment of a super-pressure balloon altitude control system, and high-performance fans have a significant impact on the altitude control capability and flight safety of super-pressure balloons. This paper proposes a mixed-flow MIX-140 fan for use with super-pressure balloons. Changes in the fan’s operating characteristics at various flight altitudes of a super-pressure balloon were investigated. First, the performance of the fan at ground level was obtained through numerical simulation and compared with measured data of the prototype to verify the accuracy of the simulation analysis. On this basis, the influences of changes in the atmospheric pressure, temperature, and fan speed on fan performance were investigated through numerical simulation. Furthermore, the MIX-140 fan was compared with an existing fan, and the variation of two parameters, namely, the ratio of inflation volume per unit time and the ratio of inflation volume per unit power, were investigated at different altitudes. Finally, the changes in the operating characteristics of the fan under different high-altitude environments were investigated through actual testing. The results reveal that changes in altitude can lead to significant changes in fan performance, and changes in the atmospheric pressure, temperature, and fan speed affect the fan’s working characteristics. Compared with the existing fan, the MIX-140 fan achieves an average increase of 295.8% in the inflation volume per unit of time, and 14.6% in the inflation volume per unit of power at altitudes of 16–20 km. The performance variation characteristics and testing methods of this proposed super-pressure balloon fan can provide a foundation and reference for the design of a super-pressure balloon control system.
