Abstract : The interaction of the aerodynamic force due to circulation, and the thrust force due to augmented jet was investigated. Total force was assumed to be the sum of aerodynamic, thrust and interaction force components. The solution of the coefficients of the total force equation was accomplished by using experimental data which was obtained from wind tunnel tests of an ejector model. The change in aerodynamic lift, due to jet effect, was a three-fold increase. The interaction force was also favorable and aided in the vertical lift of the device. Static thrust test results and rectangular test section survey procedures are included in the report. (Author)
