CONTRAROTATING PROPELLERS--DESIGN THEORY AND APPLICATION
Recent developments in design theory for contrarotating propellers are reviewed. The presentation includes: (1) a solution for the optimum circulation distribution; (2) prediction of slipstream contraction; (3) methods for computing the interactions between the forward and aft propellers; (4) numerical prediction of efficiency as a function of thrust loading, advance coefficient, and comparisons between single and contrarotating propellers; and (5) calculations for the forces and flow field velocities of a contrarotating propeller for uniform flow.
