gaS TurBineSGas turbines Rolls-Royce pioneered the use of aero-derivative gas turbines for ship propulsion back in the 1950s. Gas turbines are exceptionally power dense, enabling significant amounts of power to be placed in small spaces, and have therefore been selected to power yachts, hydrofoils, naval vessels and hovercraft. With over 1000 gas turbines in naval service, Rolls-Royce is continuing its tradition of transforming successful aero gas turbines into marine engines. The 36MW MT30 that uses Trent aero engine technology, is meeting the growing power requirements of future naval programmes in both mechanical and electric drive. Smallest of the range, the MT7, weighing just 441kg delivers 4 – 5MW and has been selected to power the US Navy’s new Ship-to-Shore Connector hovercraft. 58 59 Key features: gaS TurBineS • Designed to meet • Local or remote control MIL-S 901D shock • Full Authority Digital Key features: • Electric start Control (FADC) • Lightweight and modular • Mechanical starter for black • Minimal structural • No post shutdown restart • Local or remote control ship start borne noise restrictions • MIL-G-22077 qualified • Full Authority Digital • Shock tested to MILS-901D Control (FADC) Technical data Technical data Power (kW) Weight (kg) Dimensions (m) turbine Generator Power (kW) Weight (kg) Dimensions (m) turbine Generator LxWxH speed speed (rpm) LxWxH speed speed (rpm) (rpm) (rpm) 3000 29710 8. and generator and gearbox losses) enclosure ventilation.38 14600 1800 3900 51392 9. 40% relative humidity. 100ºF inlet temperature. the RR4500 has an exceptionally low emissions signature.
