abstract

The WR21 Intercooled and Recuperated (ICR) gas turbine has been developed to meet the future military needs for a fuel efficient, low cost of ownership, high power marine gas turbine. The engine is rated at 25.6MW (ISO) and has an outstanding pedigree derived from its two parent engines, the Rolls-Royce aero RB211 and Trent.

Having completed development in February 2000, a 3000 hour endurance test is now underway and a shock test is planned to qualify the engine for entry into service in the Royal Navy, United States Navy and French Navy. The 3000 hour endurance test commenced at DCN Indret, France in January 2001 and is planned to complete April 2002. Shock testing, conducted on the unrefurbished endurance engine, will complete in late 2002.

The three Navies have invested considerable time and effort in developing comprehensive running profiles that will thoroughly test the engine to the satisfaction of all parties. The first 1500 - 2000 hours will be conducted with the engine operating in the mechanical drive configuration, with the remaining running simulating the engine driving a conventional constant speed alternator.
