系留气球以其显著特点已应用到许多领域,今后还会有大的发展。因所处环境的风力对飞行稳定性影响较大,故抗风能力成为系统重要指标。针对无法用实验手段进行验证的空中工作姿态,一般采取计算机仿真方法进行模拟研究。介绍了系留气球的设备组成,描述了空中飞行状态,通过建立动力学模型的数学方程式,施加1-consine型离散突风模型扰动,仿真了空中球体的俯仰角和滚转角随扰动时间的关系曲线,并对结果曲线进行分析研究,以期为同型系留气球的设计方法提供某种借鉴,为浮空器使用安全提供帮助。
繫留氣毬以其顯著特點已應用到許多領域,今後還會有大的髮展。因所處環境的風力對飛行穩定性影響較大,故抗風能力成為繫統重要指標。針對無法用實驗手段進行驗證的空中工作姿態,一般採取計算機倣真方法進行模擬研究。介紹瞭繫留氣毬的設備組成,描述瞭空中飛行狀態,通過建立動力學模型的數學方程式,施加1-consine型離散突風模型擾動,倣真瞭空中毬體的俯仰角和滾轉角隨擾動時間的關繫麯線,併對結果麯線進行分析研究,以期為同型繫留氣毬的設計方法提供某種藉鑒,為浮空器使用安全提供幫助。

Tethered balloon is applied in many scopes by it, s characteristic, and have a great fu—ture. The ambient Wind influences flight stability, so Wind—resistant performance becomes the important guide line of Whole system. There is no method to validate test for air attitude, and computer simulation is introduced as usual. The parts that compose the Whole are introduced in this article, the flight state is de—scribed, the correlation curve is investigated betWeen pitch angle and time and betWeen roll angle and time by modeling dynamic equation and putting on 1-consine discrete—gust model. The numerical simula—tion is reference to this tethered balloon design, and is helpful to aerostat safety.
