Available in PDF, EPUB and Kindle. Book excerpt: This is an interim report on a theoretical investigation of the flow of air jets in ground proximity. A previous report presented a theory which included the effects of viscosity on a two-dimensional wall jet. The theory was found to be adequate for the hovering mode. This report extends the theory to iclude the cases of forward velocity and small angular displacements in hover. The theory indicates that the vortices or vortex-type flow induced by the viscosity of the air jets is of some importance to the stability of the annular jet Ground Effect Machine. The investigation is continuing with experiments to confirm the assumed vortical flow pattern. (Author).
