M.S. Thesis Proposal: Luke Battey

*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

“A Hybrid Navier-Stokes/Vortex Particle Wake Methodology for Modeling Helicopter Rotors in Forward Flight and Maneuvers”

Abstract
Maneuvering flight and high-speed flight are critical design points in any rotorcraft’s operating envelope. These conditions give complex flow phenomena, creating high stresses and vibrations. To accurately predict the flow properties over the relatively flexible rotor blades, coupling between computational fluid dynamics (CFD) and computational structural dynamics (CSD) is required.

In this work, GT-Hybrid, a hybrid wake rotorcraft CFD code that is coupled to DYMORE, is used. A vortex particle method has been implemented in place of the existing lattice methodology. Results have been obtained for two forward flight simulations and are in good agreement with flight test and wind tunnel data.

It is proposed that the GT-Hybrid solver with the vortex particle method be further evaluated by simulating three maneuvering flight conditions – a pull-up maneuver, and two dive-turn maneuvers.
