Abstract
The design method based on lifting-line and lifting-surface theories for highly skewed contra-rotating propellers was studied. An improved approach for designing the pitch distribution and camber surface was devised and incorporated into the existing design procedure to enhance its efficiency and accuracy. The design example and its numerical validation results indicate that the improved procedure is capable of enhancing computational efficiency and producing smooth blade geometries. The present method provides a useful tool for the design of highly skewed contra-rotating propellers.
