Project Description: This project is focused on developing testing capabilities in the Arizona Polysonic Wind Tunnel, which represents the largest facility of its kind at any US university. One key roll of facilities like this is to generate 'aerodynamic databases' i.e. measurements of forces and moments that act upon a vehicle at any given condition (Mach, altitude, attitude, etc.). Since these databases are dense with test points, it is highly advantageous to sweep through multiple attitudes during each test. To that end, a Model Positioning System has been in development. Currently, models may be pitched and vertically translated; however they critically lack the ability to roll that replicates sideslip flow conditions on a vehicle. The intern shall take the existing concept for this roll device (a 'roll pod') and mature it to fabrication and assembly. They shall then integrate the device with the broader Model Positioning System and perform tests to verify operation.
NASA Relevance: Various NASA facilities play a major role in populating aerodynamic databases for academia and industry. Establishing this capability in a few facility offers great potential for the advancement of experimental diagnostic approaches and provides a pipeline for workforce development as students work in the facility and move on to their future careers.
Work Description:
- Establish requirements for the roll pod, considering the range of potential future uses
- Finalize the system design to ensure that requirements are met
- Oversea fabration and purchasing of subcomponents
- Assemble system and integrate to existing positioning system
- Perform initial tests to verify operational capability
Open or Reserved Project: 1 position reserved, but mentor may consider new student if requested student not awarded.
