Abstract
As known already by experimental study carried out previously the power required for a recirculating Air Cushion Vehicle depends on both the design and operating conditions, and the minimal values of the power can be achieved by the suitable combinations of parameters such as recirculating flow, hover height and the geometry of the recirculating air intake.
In this study the simple flow model of recirculating jet based on the results of flow visuarization using air-bubble technique is proposed, and above mentioned characteristics of recirculating jet are explained by the analysis based on the flow model.
