T63 REGENERATIVE ENGINE PROGRAM (EXTENDED ENDURANCE AND ENVIRONMENTAL TESTING)
Abstract
The third set of regenerators successfully completed a 150-hour endurance test on the first attempt with no indication of regenerator performance deterioration or loss in structural integrity. The regenerators accumulated a total of 191 hours and in excess of 278 starts and 4500 accelerations. Overall engine performance was within the 5% allowable depreciation at the completion of the test. The second set of hardware successfully completed carbon fouling and sand and dust ingestion tests with no performance loss due to carbon fouling or any evidence of erosion or loss in structural integrity due to sand and dust ingestion. The analysis of the sound survey data obtained under the original contract indicated that the regenerative engine perceived noise level was one to three decibels lower than that of the nonregenerative engine when installed in the YOH-6A helicopter. The additional testing covered in this report again demonstrated the feasibility of a regenerative engine as a powerplant for aircraft operation. No problems were encountered which would indicate that a regenerative engine would be more susceptible to performance depreciation than the standard T63 engine.
