Abstract
The optimization of installed power in a low-speed overland ACV is shown to depend heavily on the minimization of skirt/terrain interaction drag, which is in turn shown to depend critically upon lift-air supply. The influence of hoverheight, terrain roughness and porosity, vegetation, and vehicle speed on drag is examined in the light of data from the CASPAR vehicles. An analysis is proposed by which the data can be reduced to give a lift airflow applicable to any vehicle having a segmented skirt, operating over a range of specified terrains. Tentative values for these flow coefficients, together with associated drag coefficients, are given.
