Performance Characteristics of a Jet Flap Propeller

Abstract

The performance characteristics of a marine propeller with a jet flap was investigated. It was found that the jet flap effectively reduced propeller blade cavitation and that for a given advance coefficient the thrust was considerably increased by using the jet flap. The propeller efficiency decreased somewhat, primarily because of the power required in delivering the jet.
