Multi-Quantum Cascade Laser based sensors for high-speed characterization of flow parameters in hypersonic tunnels

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. 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.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
