AERODYNAMIC CHARACTERISTICS OF ANNULAR JET FLOW OVER A SCREEN,
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.
