Description

The design and development of a compact, rugged, cost-scalable optical diagnostic for measuring temperatures, species concentrations, and velocities to advance research vital to enabling the next generation of high-speed air platforms is proposed.nbsp;The sensor design overcomes many challenges associated with making measurements in the extreme environments of hypersonic and reactive flows. The system is fast, obtaining MHz (up to GHz) rate measurements that can resolve fluctuations and transient events. The monolithic structure is inherently compact, which lends itself well to low-profile packaging that can be easily integrated into existing ground testing platforms with a path towards onboard monitoring for flight tests. The system is robust, as the monolithic platform and single optical path are insensitive to vibrations and misalignment from mechanical loading, and thermal management is straightforward.
