Study of Contra-Rotating Coaxial Rotors in Hover: A Performance Model Based on Blade Element Theory Including Swirl Velocity
… evaluate the performance of a counter-rotating coaxial rotor system. As it is based on the blade element theory, it could be used as a design tool where the engineer can modify all parameters - rotor radius, blade pitch distribution, tip velocity, rotor spacing, number of blades, blade chord, …

An acoustical based approach to conceptual design of non-traditional rotorcraft configurations
… investigates three configurations of rotorcraft: coaxial rotors, ducted rotors, and ducted coaxial rotors, to provide insight on how design configuration changes the acoustics of these vehicles. The methodology developed is a parametric environment to provide detail on influential parameters for a …
