Abstract:

A detailed experimental investigation of the aerodynamic characteristics of annular jets impinging on a screen is presented. Knowledge of the interactions of annular and plane jets with the ground which generate a lift force should be of prime interest to the design of air cushion vehicles. Six different annular nozzle configurations were investigated 1 three with an annulus width b 8 mm and angles of inclination phi 0.30 and 45 deg with respect to the vertical 2 two with an annulus width b 20 mm with angles of inclination phi 0 and 45 deg and 3 one with an annulus width b 25 and angle phi 30 deg. The design details of the nozzles are described and geometrical dimensions are given. The technique used for interpretation of the experimental data and measuring techniques are also described.
