HYPERSONIC VEHICLE SHAPE DISTORTION SENSING WITH OPTICAL FIBRE BRAGG GRATINGS
Abstract
This project will demonstrate and optimize the application of established fiber-optic based measurement techniques for use on novel hypersonic fluid-thermal-structural interaction (FTSI) experiments, demonstrating a pathway for application to flight experiments. Optical fiber sensing is attractive to both reduce the intrusiveness of the hardware and its sensitivity to high-temperature environments, while also being immune to electromagnetic interference and versatile in terms of the variety of measurands that can be sensed. The techniques will be developed to support FSI measurements on a simple cantilevered plate model in UNSW Canberra’s supersonic wind tunnel before being applied to FTSI experiments in the TUSQ hypersonic wind tunnel. The technique will be focused on Bragg-grating based measurements of strain distribution via a dedicated fiber optic network.
