INVISCID-INCOMPRESSIBLE-FLOW THEORY OF NORMAL AND SLIGHTLY OBLIQUE IMPINGEMENT OF A STATIC ROUND JET ON THE GROUND,
AIR VEHICLE CORP LA JOLLA CALIF
Pagination or Media Count:
An inviscid-incompressible-flow theory of normal and slightly oblique impingement of a static round jet on the ground is developed and compared with the results of a bench test. The velocity distribution along the ground and across the jet exit, the location of the free stream tube boundary, and thrust ratios at constant power and constant total head are presented as functions of the height of the jet exit above the ground and of the angle of tilt.
