通过对平流层飞艇定点过程的飞行状态、控制模式和工作环境的分析,建立了飞艇在定点阶段的热力学和动力学模型,并用C++可视化语言对控制方程编程求解。对无黑皮不充放空气和有黑皮充放空气两种不同状况、不同控制模式下的飞艇进行了飞行特性的数值模拟和对比,获得了两种不同状况下飞艇膜、黑皮、内部空气和氦气的温度以及飞艇的高度随时间的变化关系。结果表明:太阳辐射、飞艇的控制模式和太阳能电池阵列对其定点性能有较大影响。
Based on the analysis of the flight state, control mode and working environment of the fixed-point airship in the stratosphere, a thermodynamic and kinetic model of the airship in the fixed-point phase is established. The control equations are programmed and solved in C ++ visual language. There are two different states of non-black air without charging and discharging air and black air with charging and discharging air. The numerical simulation and contrast of the airship in different control modes are carried out, and the airship membrane, black skin, internal The temperature of the air and helium, and the height of the airship over time. The results show that solar radiation, control mode of airship and solar array have great influence on the fixed-point performance.
