New Gas Turbine Test


The WR-21 intercooled recuperated (ICR) advanced-cycle gas turbine ship propulsion engine has successfully completed the eighth in a planned series of 10 full system tests. It is being developed for naval warship applications by an industry team led by Northrop Grumman Corporation.
These latest engine tests, which took place at the United Kingdom's Defence Evaluation and Research Agency test facility in Pyestock, England, and lasted about 260 hours, were designed to test the WR-21's high-pressure turbine, engine control and combustor systems and other system components. Preparations are under way for the final WR-21 developmental engine test at Pyestock, which is set to begin in February and run through June. This will lead to a final 500-hour endurance test of the WR-21 next autumn at the US Navy's test facility in Philadelphia, Pa. A planned 3,000-hour qualification test of the engine is expected to follow starting in mid-2000.
The WR-21 engine is being developed to provide more fuel-efficient propulsion for naval ships. The WR-21 is also a candidate engine for European advanced combatants, and both the United Kingdom and France have invested in its development. The Project Horizon consortium, which includes the United Kingdom, France and Italy, may include the WR-21 in the design for its New Generation Frigate.
Unlike conventional marine gas turbine engines, the WR-21 features a recuperator downstream of the turbine that recovers energy from the exhaust gas to increase fuel efficiency. This translates into extended ship range for a given fuel capacity, more un-refueled time on-station for a given fuel capacity, or reduced fuel storage requirements for a given range. The WR-21 engine also will comply with International Maritime Organisation emission requirements for marine vessels.
