This paper discusses the basic operating characteristics of ducted propulsors of all types, but with primary emphasis on ducted propulsors with no stationary blade rows. Both blade element theory and momentum principles have been used to design and analyze ducted units with little attempt to correlate between the two. Momentum methods seem to be more appropriate for performing the parametric analysis commonly used in the preliminary stages of a design and for determining the basic operating principles while blade element theory appears to be better suited for the final blade shape design. The paper, among other things, develops some connections between the concepts and parameters used in the two methods.
