PROPELLER BLADE ELEMENT MOMENTUM THEORY WITH VORTEX WAKE DEFLECTION

1 Abstract Various propeller theories are treated in developing a model that analyses the aerodynamic performance of an aircraft propeller along with the construct and behaviour of the resultant slip-stream. Blade element momentum theory is used as a loworder aerodynamic model of the propeller and is coupled with a vortex wake representation of the slip-stream to relate the vorticity distributed throughout the slip-stream to the propeller forces.
