N06-111 TITLE: High-Turbine Operational Sensor Assembly
TECHNOLOGY AREAS: Air Platform
ACQUISITION PROGRAM: Joint Strike Fighter
OBJECTIVE: Develop innovative hot-section sensors (or an assembly of sensors) that would be positioned closer to the combustor outlet to better assess the high-pressure, and low-pressure turbine component environments and transients. Rotor-speed variable and time-varied turbine gas-stream and/or component pressures, temperatures and airfoil dynamic responses are needed.
DESCRIPTION: The assembly should enable the determination, monitoring and tracking of failure modes of interest (through near real-time data processing methods not included herein, but in coordination with the other SBIR and/or engine OEMs schemes). Examples of the types of safety related parameters and life limiting failure modes are: the airfoil structural response normality-state tracking (for sudden deviations and with aging), cooling blockages or leakages from cracks or abnormal holes, oxidation, corrosion, thermal-mechanical failure (TMF), creep, life-cycle fatigue (LCF) and high-cycle fatigue (HCF). Abnormal- or damaged-state sensing is needed, especially if coupled with an upstream issue such as a hot-start or an EDO/FOD event.
PHASE I: Define the sensing and interface requirements, to include the expected data transmission approach. Initiate the design to the conceptual-level for one or several engine systems, like the JSF P&W F135 or GE/RR F136, the SH60 GE T700, F/A18E/F GE F414, E-2C RR T56-427 or a similar future naval air systems platform. A prototype sensor assembly may be demonstrated in bench tests if feasible.
PHASE II: Produce detail design(s) and prototype the assembly. This effort should be performed in strong coordination with selected-engine OEM and/or multiple designated 2nd-party partners (especially relating to signal data bus transmission scheme, data acquisition and processing approach, and the specific assembly-interface to the engine case).
PHASE III: Finalize hot section sensor assembly integration with major DOD end users and engine manufacturers and conduct necessary qualification testing.
PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: This integrated sensing capability, sensing in closer proximity to the combustor would provide better information for control and avoidance of exceedances that damage expensive turbine components. The technology is directly transferable to commercial gas turbine engine applications.
