N08-037 TITLE: High Temperature Sensing Parameters

TECHNOLOGY AREAS: Air Platform, Materials/Processes, Sensors

ACQUISITION PROGRAM: Joint Strike Fighter Program Office, Propulsion IPT, ACAT I D Program

OBJECTIVE: Develop high temperature sensing devices that measure parameters other than temperature and pressure, such as heat flux, flow, strain, and gas species.

DESCRIPTION: Previous research and development (R&D) efforts for high temperature sensing have largely focused on temperature and pressure readings. These sensor types are expected to be commercially available in the foreseeable future. Future R&D efforts for high temperature sensing must focus on other sensing parameters, such as heat flux, strain, and gas concentration for advanced engine prognostic and diagnostic monitoring. Industry desires to incorporate such sensors in regions such as the turbine hot section to achieve in-situ, real-time measurements. Sensors that can survive this environment are necessary to advance the state of the art. Sensors must be able to survive beyond 600�C and show merit to meet material expectations of reliability and robustness. The sensor must also include a realistic packaging scheme for the environment and application.

PHASE I: Demonstrate the feasibility of the proposed sensor types and the packaging approach. Describe the manufacturing feasibility of the sensor and packaging necessary for commercialization efforts. Experimentally demonstrate feasibility of the proposed sensor at a laboratory scale.

PHASE II: Fabricate and characterize several full prototype devices in a laboratory environment and in a representative turbine test bed system, such as a burner rig or other applicable device.

PHASE III: Conduct necessary qualification testing of the device to merit further investment and consideration for military turbine engine platforms. Work together with OEM to develop a business plan and necessary IP, and seek necessary investment to support the product/process/service for the OEM military provider.

PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: Both military and commercial turbine engine manufacturers and operators have a need for advanced sensors. The ability to gather real-time data from in-situ sensors will provide enormous benefits and useful information.
