Snapshot Imaging laser Displacement Sensor for Hypervelocity Diagnostic Testing
Project runs from 09/14/2016 to 09/10/2019
Reentry and hypersonic low- and mid-altitude vehicles are subjected to significant aerothermal heating as kinetic energy is dissipated into the atmosphere. Designing a vehicle to withstand aerothermal heating and other associated aerodynamic loads poses a significant engineering challenge in materials research. In the development of materials- and physics-based models, significant testing is conducted in hypersonic wind tunnels. Deformations in a surface or material can be related to internal stresses; thus, measuring such deformations, in situ, within the hypersonic environment must be achieved without distrubing the hypersonic characteristics of the flow. This project will develop high speed optical metrology equipment, optimized for use in hypersonic wind tunnel testing.
