平流层飞艇的控制模式对其定点特性的影响

 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。

Effect of the Control Style of a Stratospheric Airship on Its Floating Performance

Based on an analysis of the flight state, control style and working environment of a stratospheric airship, a physical model was established to describe its heat transfer and aerodynamic behaviors during its floating flight, and a visible C++ program was written to solve the governing equations. Numerical simulations and comparisons of their floating characteristics were conducted respectively for the airship covered with/without black-skin, and controlled with/without pumping in/out air. Variations of the ...
