The Momentum Equation for a Static Hovercraft at Zero Incidence

Extract

The technical note by Dr. Alexander implies that hovercraft jet performance might be better than simple theory predicts for values of 1/x greater than 4. The experimental points used to compare with theory were obtained at the beginning of hovercraft development, but subsequently a number of British and American reports have been issued whose data can be interpreted to give points for comparison with theory. These results show that the simple theory overestimates the performance of the jet.
