Abstract:

An engineering method is presented for calculating air-cushion vehicles ACV with two peripheral nozzles. The method is based on a study previously published by the author On the aerodynamic calculation of air-cushion vehicles. Sb Samoletostroyeniye i tekhnika vozdushnogo flota, vyp. 6. Izd-vo KhGu, 1965. It is assumed that two peripheral jets I and II of an incompressible fluid join at the point K and that jet II contracts by a factor M after contacting the ground. Formulas were derived for the main characteristics of ACVs with two peripheral jets from these characteristics the lifting capacity, the air flow rate, and the required power relative to the ACV geometry and its operating regimes can be determined.
