The turbine itself was designed primarily by Rolls-Royce with significant marine engineering and test facility input from DCN, with Northrop Grumman responsible for the intercooler, the recuperator and system integration. [1] [2] WR-21 development draws heavily on the technology of the successful Rolls-Royce RB211 and Trent families of gas ...
MAN Energy Solutions builds exhaust-gas turbochargers [48] using single-stage radial and axial turbines to create high charging pressures. The performance spectrum of these chargers, which are used both in two-stroke and four-stroke marine engines and in stationary systems, ranges from around 300 kW to 30,000 kW of engine power.
The Rolls-Royce Marine Spey is a marine gas turbine based on the Rolls-Royce Spey and TF41 aircraft turbofan engines. [1] The Marine Spey currently powers seven ship classes including the Royal Navy's Type 23 frigates and provides a power output of 19.5 MW (about 26,150HP). The Marine Spey incorporates technology from the Tay and RB211.
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats , most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller , or less frequently, in pump-jets , an ...
The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation.The LM2500 is a derivative of the General Electric CF6 aircraft engine.. As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships. [1]
In 1994, the Lycoming Turbine Engine Division was acquired by AlliedSignal, becoming part of AlliedSignal Aerospace, and Honeywell Aerospace in 1999. [3] In 1999, AlliedSignal/Honeywell formed a joint venture with MTU Aero Engines called Vericor Power Systems LLC to manage its marine and industrial gas turbine products. In June 2002, MTU ...

The propelling nozzle converts a gas turbine or gas generator into a jet engine. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). [18]
