The Intercooled Recuperated Gas Turbine Engine System (ICR) is being developed by the United States Navy (USN) for shipboard application as a prime mover. The major development goal of the program is reduced fuel consumption relative to the LM2500, the current fielded gas turbine prime mover. This paper describes a 500-hour endurance test of the ICR system. The test was conducted at Naval Surface Warfare Center Carderock Division (NSWCCD), Philadelphia, in accordance with USN requirements which mimicked the qualification requirements for the system.
Data to assess the capability of the ICR to pass the qualification test was collected. Overall, the ICR has demonstrated a readiness to commence qualification testing.
The ICR completed the test with a total accumulated operating time of 457 hours and total endurance time of 322 hours. Achievement of the planned 500 endurance hours was precluded by persistent facility waterbrake problems.
