Abstract
A method and system for generating a set of values for respective ones of a set of parameters used in determining rotor blade profiles for a coaxial rotor system. The method includes establishing (302) a ratio of respective desired thrusts of an upper rotor (102, 602) and a lower rotor (104, 604) of the coaxial rotor system based on a desired performance of the coaxial rotor system, and determining (304) the set of values of the set of parameters from the desired thrusts ratio based on a torque balance condition between the upper rotor and the lower rotor of the coaxial rotor system.
