All UK nuclear-powered submarines entering service in the last half-century have featured Rolls-Royce turbo-generators. A large number of turbine products have also been designed for naval surface ship applications, many of which remain in service today around the world.

Turbo-generators are designed to convert the energy in steam into electrical power, essential for sea-going craft, particularly submarines that must maintain a breathable atmosphere. The turbo-generators run at a fixed speed and are designed to be both quiet and resistant to severe mechanical shocks.

Design and methods

We design bespoke steam turbines using cutting-edge, integrated thermodynamic/mechanical tools that are capable of complex three-dimensional (3D) blade design and performance prediction.
