The MT7 Marine Gas Turbine

Product catalog summary

Overview
The MT7 Marine Gas Turbine by Rolls-Royce is a compact and powerful engine designed for demanding marine applications. It shares its core architecture with the AE1107C-Liberty aero engine, known for powering the V-22 Osprey tilt-rotor aircraft.

Power and Efficiency
The MT7 delivers between 4 to 5MW of power, offering a high power-to-weight ratio and low through-life costs. It is fuel-efficient and retains performance over time, making it suitable for various propulsion system configurations, including mechanical and electrical drives.

Heritage and Support
Part of the AE family of aero engines, the MT7 benefits from a robust production and support network. With over 48 million operating hours and 4,500 engines delivered, the MT7 is a proven, low-risk solution for modern marine applications. It also offers upgrade options to increase power by up to 20% or extend engine life.

Technical Specifications
The MT7 features a twin-shaft axial design with a 14-stage compressor, effusion-cooled annular combustor, and a two-stage power turbine. It includes a dual-channel Full Authority Digital Electronic Control system (FADEC) and modular construction. The engine is designed to resist sand erosion and salt corrosion, ensuring optimal performance in challenging environments.
