A Modular Sensor Suite for Propulsion Testing

nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; Enrsquo;Urga Inc. will evaluate the feasibility of utilizing a modular sensor suite as general purpose combustion diagnostic for rocket propulsion systems. nbsp;The two key issues that will be addressed during the Phase I research work are: (1) the feasibility of configuring a modular tomographic sensor suite that can be used measure path integrated properties in high speed turbulent reacting flows, and (2) the feasibility of obtaining spatially and temporally resolved information from these measurements.nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; Three tasks are planned to be completed during the Phase I work to address the feasibility of the modular tomographic suite. nbsp;The first task is to design and integrate a breadboard version of the modular tomographic suite to measure path integrated extinction and emission from reacting flows. nbsp;The second task is to develop a configurable algorithm to obtain relevant spatially and temporally resolved information from the measurements. nbsp;The third task is to evaluate the system using laboratory scale experiments. nbsp;It is anticipated that at the end of the Phase I project, the feasibility of obtaining relevant local information from path-integrated measurements using a modular tomographic suite will be demonstrated conclusively. nbsp;For Phase II work, a prototype and customized modular tomographic system will be fabricated and delivered to NASA for use at the Stennis Space Center. nbsp;The customization for the Phase II prototype will incorporate specific spatial, temporal, and species measurement needs from Stennis Space Center. nbsp;The prototype system can be readily incorporated into the Stennis Space Center#39;s test facilities.
