Wind resistance requirements and test methods for tethered balloons

1 Scope

This document specifies the wind resistance requirements for tethered balloons in both ground-tethered and air-tethered states, and describes the corresponding test methods.

This document applies to the testing of the wind resistance of tethered balloons; other aerostat products should refer to this document for implementation.

3 Terms and Definitions

The terms and definitions defined in GB/T 43328 and the following terms and definitions apply to this document.

4 Symbols

The following symbols apply to this document.

vmax1 --- Maximum wind speed that can be resisted in the air, in meters per second (m/s).

vmax2 --- Wind speed at which the anchorage withstands wind, measured in meters per second (m/s).

v1 --- 60%~80% of the value of vmax1, in meters per second (m/s).

v2 --- 60%~80% of the value of vmax2, in meters per second (m/s).

Note. The specific values of v1 and v2 shall be determined in consultation with the user based on user requirements, ambient wind speed, and economic considerations for the experiment.

5 Wind resistance

Unless otherwise specified, the wind resistance of tethered balloons can be determined based on mission requirements and design specifications, with reference to similar products both domestically and internationally.
