WIND TUNNEL TESTS AND ANALYSES FOR GROUND MOUNTED AIR-SUPPORTED STRUCTURES

Abstract

The objective of the program is to provide tentage information based on wind tunnel test data that can be applied either to the evaluation and improvement of existing ground mounted air-supported tents or to the design of such future structures. The wind tunnel investigations consisted of detailed testing of twenty-six tent models to include sixteen single wall tents (ten with non-porous and six with porous fabrics) and ten double-wall tents. Tests were conducted at stabilized wind speeds up to 105 miles per hour. Results of the wind tunnel investigations and stress analyses were incorporated and includes comprehensive, practical design data suitable for engineering reliable, stable, single and double-wall air-supported tents. Data, in general, are presented in non-dimensional coefficient form, and therefore, are applicable to full scale tents within the range of the parameters investigated. Design information is presented as charts and tables on tent aerodynamic force and moment coefficients, anchor and guy line coefficients, structural deflection, material stresses and packaged volume, and weight.
