为了获得大气条件的性质，已经发展了许多种观测技术。较先进的大尺度气流观测技术有卫星设施遥感、雷达或多普勒雷达远距离观测等，而传统的固定地点气象站数据只能提供有限的局地尺度气流信息。如果系留气球的站立力学对强风有较强的抵抗能力，并且气球的运动对所有风向和风向的变化都是稳定的，那么系留气球也可以用于局部气流的观测。本文提出了一种用于流量测量的紧凑型系留气球（直径约2米），并利用风筝对气球高度的保持和运动的稳定性提出了挑战。在实验中估计并证实了作用在气球上的力平衡与气球高度或位置的关系。虽然单个风筝的升力工作成功，但由于它们的张力相互作用，多个风筝在气球的牵引力方面的表现较差。风筝支撑的紧凑气球由于体积小，只造成较低的空气阻力，因此可以漂浮超过300米。
Many kinds of observation techniques have been developed to obtain the properties of atmospheric conditions. The advanced observation techniques of the flow in relatively large scale are remote sensing by satellite facilities, long range observations by radar or Doppler Sodar, etc., while data from conventional climometers set at fixed places are merely limited information about local scale flow. Captive balloons are also available and feasible for the observation of local flows if their standing mechanics are robust against the strong wind and the motion of balloon are stable for all wind direction and the change of wind direction. In this paper, a compact captive balloon (about 2m diam.) for flow measurement is proposed and the preservation of balloon height level and the stabilization of its motion are challenged by using a kite. The relation between force balances acted on the balloon and the balloon height or position was estimated and confirmed in experiments. Although the lift force of single kite worked successfully, it is found that the performance of plural kites is less in the traction of balloon since the interaction of their tensions. The compact balloon supported by the kite enabled the over 300m floating by virtue of the small size causing only low air resistance.
