An important element of this work will be the development of criteria to optimize the sensor design (absorption transition selection and modulation strategy) for optimum sensor performance for specific RDE operation conditions. Assuming Phase I success, the Phase II work will optimize and construct a second-generation prototype sensor for testing at DoD aeroengine test facilities, improve the design to account for lessons learned, and deliver a validated and optimized third-generation sensor for RDE research to the designated DoD point of contact. Benefits: A first-generation laser absorption based sensor for time-resolved measurements of combustion product mass fractions and gas temperature for RDE systems would greatly enhance the understanding and development of advanced propulsion systems. Such instrumentation could be adopted for a wide range of combustion applications from rockets and gas turbine engines to industrial burners. Such an experimental diagnostic system could be used in the development, testing, and day-to-day operation of propulsion and industrial combustion systems. The market for these instruments would include universities, research laboratories, and industrial burner manufactures. Return
