Prognostics for Blisks and Rotors in a Modern Engine

"This proposal is aimed at developing comprehensive prognostics and diagnostics for blisks and rotors. A system would be designed and deployed into Williams FJ44 pacer engine. This engine accumulates operating hours in a test cell at Williams. Access hasbeen offered to Hood Tech for this purpose. The remainder of this proposal outlines this plan, linking it to parallel test activities Hood has scheduled in spin pits and test cells. This project is relevant to Hood Tech's continuing relationship with PW,specifically its JSF F119 program. P&W has asked Hood Tech to contribute PHM algorithms to its CEDU for this engine. This PHM work on the FJ44 is very likely to influence that EDU system on the JSF.Another potential outcome is an EDU subsystem for the FJ44. Hood Tech is not currently familiar with the customer demand for an EDU on the FJ44. Execution of this proposed work will bring familiarity with this potential market. Entry into that market ismost likely to be through Williams and very possibly in partnership with an established supplier of EDU's, possibly Hamilton Sundstrand or Israel's RSL Electronics. In such a relationship, Hood Tech would most likely license the established algorithms tothis commercial partner.A third commercialization possibility is the application, as engineering contractors or consultants, of the developed technology to any other turbine engine. This is as likely to be applied to terrestrial as to
