NASA's interest in civil rotorcraft research prompts for a computational tool which has an Integrated Design Environment that is easy to learn and be robust and computationally efficient. The proposed design tool accomplishes this goal, especially in areas where geometric design changes are being considered and wind tunnel testing is integral to the design study. The tool can be effectively used for rotorcraft and V/STOL aircrafts where quantification of parametric variation in the design is essential for success.
The integrated Design Environment with a simple module for geometry manipulation and tools for pre-processing and post-processing CFD simulation will be an asset to any organization with a need to analyze a rotorcraft design or develop a new design. Incidentally the tool acting as a computational wind tunnel will be an asset to other government agencies including ARMY, NAVY and AIR FORCE where wind tunnel testing of rotorcraft and V/STOL aircrafts is routine. In the rotorcraft industry, the proposed tool can be used to assist during the design process. The tool will be designed to be versatile and enable the user to easily vary design parameters. In the educational institution the tool will help the students to gain insight on different flow phenomena, the effect of geometric variation and wind tunnel walls on the flow and the performance of a rotorcraft.
