CALCULATED PARAMETERS OF AIR-CUSHION DEVICES WITH NOZZLE DEVICE AT HOVERING CONDITION,
Abstract
Hovering over a solid surface is one of the fundamental conditions for which calculations of the aerodynamic and power characteristics of an ACV must be made. By the method presented for calculating an ACV with a double-flow annular-nozzle arrangement, the power characteristics and aerodynamic parameters for the fan can be found if the weight of the vehicle, its hovering height, airflow configuration, and the nozzle arrangement are known. A formula is derived for finding the power required per ACV unit weight, which varies with the ratio G/S (G = weight of the ACV; S = overall area of the nozzles). (Author)
