 The WR-21 is the first production aero-derivative gas
turbine to incorporate compressor inter-cooling and
exhaust heat recuperation technologies that deliver
low specific fuel consumption across the engines entire
operating range. The 25MW engine offers a 25-27 per
cent fuel saving over current simple cycle marine gas
turbines by improving efficiency at all powers.
Extensive use of aero parent design
data and components improve turbine efficiency and give
the WR-21 outstanding reliability.
Features and benefits:
- 27 per cent lower fuel consumption than simple cycle
gas turbines
- Power turbine derived from the Trent 700 and Trent
800
- Radial combustors for optimum maintainability
- Modular for ease of maintenance
- Reduced IR signature
The WR-21 uses proven reliable components from current
Rolls-Royce RB211 and Trent engines as its core, to
make a truly modular engine for ease of maintenance
and reduced through life costs.
The gas generator and power turbine consists of 12
interchangeable pre-balanced modules. Because of their
size and low weight, these modules can be removed and
new modules can be fitted to reduce maintenance costs
and down time.
