The Linearized Unsteady Lifting Surface Theory Applied to the Pump-Jet Propulsive System.

Abstract

A theoretical analysis is developed treating the 'Pump-Jet' propulsive unit comprised of stator, rotor and enshrouding nozzle by using the unsteady lifting surface theory. The analysis takes into account accurate geometry, realistic flow conditions and hydrodynamic interactions between all lifting surfaces of finite thickness distribution. The system is assumed to be immersed in a non-uniform flow of an incompressible fluid. Expressions have been developed for loadings on all interacting surfaces and corresponding resulting forces evaluated at proper frequencies dictated mainly by those of the rotor. (Author)
