The paper presents an outline of a new theoretical method for the calculation of the off-design performance characteristics of ducted propellers. The model for the duct performance calculation is an advanced non-linear model based on surface vorticity distribution techniques. The propeller model is a combination of principles postulated by momentum, blade-element and lifting line with lifting surface corrections theories of propeller action.
