Propeller Analysis using Adjoint Method

To cater to the increasing passenger volume in air transport and subsequently adhere to the environmental regulations, there is a renewed interest to research the propellers. Given its aerodynamic efficiency, propeller-driven aircraft are being sought as a viable option to be used for short-range passenger transport as well as their application using electric propulsion. With the limited energy density of the current batteries for electric propulsion and attention to emissions from the increased number of turboprop aircraft in future, it is crucial to assess sensitivity of the propeller's performance to variation in shape design of the blade. This study combines the adjoint method with computational fluid dynamics to determine the sensitivity of propeller's performance parameters to variations in the blade's shape design. This goal is met by comparing the propeller aerodynamic analysis with SU2 and ANSYS Fluent, and then implementing SU2's adjoint capabilities for performing a design sensitivity study. The resulting understanding of the sensitivity of the propeller's performance parameters to the variation in blade shape design can be used as an input for future design studies aimed at designing efficient propellers.
