Measured aerodynamic forces on a satellite-type vehicle constructed from tungsten wire cloth are presented. The test medium was nitrogen, with a Mach number of 10. 15 and a Reynolds number of 388in. The feasibility of using force models of this type is demonstrated. Because no other data on such a model are available to the author, no detailed comparison of aerodynamic features is offered. Drag coefficient at small angle of attack was found to be approximately the same as a roughly similar shape of nonporous construction, but corresponding lift coefficient slope was markedly reduced by the porosity.
