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

Abstract:
The advent of smaller, lighter Urban Air Mobility (UAM) and Unmanned Aerial Vehicles (UAV) focus on missions that are performed primarily in urban and nap-of-the-earth environments. These vehicles, with slower forward flight speeds and reduced mass ratios flying through large transients, have led to a renewed interest of gusts (discrete turbulence) and their impact on vehicle response. This knowledge is required to ensure both safety and the reduction of noise during operations, in particular during takeoff and landing (terminal operations).
As such, a greater understanding of the flow physics of large canonical wing-gust interactions is required in order to accurately model these physics during vehicle design, especially for manned and autonomous control law development. This understanding requires the development of physical and computational experiments that accurately capture the details of the flow field so that existing linear models can be expanded or new theories developed.
This proposal will present the development of a computational methodology to model nonlinear sharp-edged transverse gusts and validate the results against experimental data.
