Abstract:

This report describes the work accomplished during the 12-month Phase I portion of a 32-month program for the advancement of toroidal rotary regenerator technology for small gas turbine engines. The regenerator component work included analytical and experimental evaluation of candidate heat transfer surfaces where previous data did not exist experimental determination of matrix airflow distribution and corrective measures and refinement of seal system components, including all-metal inner diameter seals. The optimum matrix and seal configurations determined from these component tests were evaluated in an existing regenerator which was run at conditions simulating small gas turbine operation. As a result of these component investigations, major improvements in regenerator technology were made and were incorporated into the design of a flight-weight high-effectiveness toroidal rotary regenerator designed during Phase I.
