abstract

In December 1991, the United States Navy awarded a contract to Northrop Grumman Marine Systems (then Westinghouse Electric Corporation) for the design and development of an intercooled, recuperated gas turbine engine system (ICR). The system is known by the designation WR-21. The development team includes Northrop Grumman as the prime contractor and system integrator, Rolls-Royce (RR) as the gas turbine developer, Allied Signal as developer of the recuperator cores, recuperator housing, and intercooler cores, and CAE Electronics Ltd. as the digital controller developer.

After the development program began, the Royal Navy and the French Navy became interested in the ICR technology and have since become active program participants. The Navy team’s joint goal is to design, develop, and qualify a fuel efficient engine for future surface combatants. This paper provides an overview and update of the WR-21 requirements, principles of operation, system description/performance, and the development program.
