Abstract: Method And System For Increasing Propeller Thrust A method and system for increasing propeller thrust are provided. The method comprising measuring initial values of geometric parameters of one or more airfoil sections at one or more span-wise locations along a propeller blade; calculating aerodynamic characteristics of the one or more measured airfoil sections based on the initial values of the geometric parameters; conducting aerodynamics analysis including varying values of the geometric parameters to obtain one or more permutations of the calculated aerodynamic characteristics of the one or more measured airfoil sections; identifying airfoil sections which show an improvement in aerodynamic efficiency with variation in the geometric parameters values, and corresponding improved geometric parameters values as indicated by results of the aerodynamics analysis; and modifying the identified airfoil sections to exhibit said improved geometric parameters values as determined based on the results of the aerodynamics analysis.
