摘　　要：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。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.
