系留气球现已应用到许多领域,针对可能出现的主要问题,有些无法用实验手段进行验证,因而采取计算机仿真加以研究。介绍了系留气球的工作状况,描述了空中逃逸的飞行过程,通过建立动力学模型的数学方程式,仿真了升空高度和升降速度与时间的关系。对同型系留气球的设计方法提供参考,为浮空器使用安全提供帮助。 Tethered balloons have now been applied in many fields, some of which may not be validated experimentally for major problems that may arise, and computer simulations have been used to study them. The working conditions of tethered balloons are introduced, the flight process of flight in the air is described, and the mathematical relationship between the altitude and the ascending and descending speed and the time is simulated. The same type tethered balloon design methods provide a reference for the safety of aerostats to provide help.
