Turbine D
We are using 2 x LM 2500's to power a 99m fast ferry. The craft should atain speeds of up to 50 knots. The LM 2500's will be rated at 22mW each. Each gas generator is coupled via fluid (exhaust gas) to a power turbine which is directly coupled via a clutch to a reduction gearbox and onward via a shaft to a thrust bearing and finally a large water jet. The power turbine is rated at max 3600 rpm driving the shaft at approximately 600 rpm. Engine control is via the power turbine. These engines will run on LNG gas and liquid fuel (gas oil), dual fuel. A world first for a high speed craft.
We have various shutdowns built in to the engine as well as slowdowns which return the engine to an idle state. Shutdowns will shut the engine down irrespective of the Captain's wishes to "save the engine". Shutdowns will include, low low lube oil pressure following an audible warning, overspeed following an audible warning, fire in the turbine enclosure, failure in part of the gas system, gas detection, gearbox low low oil level after a 10 sec delay etc etc.
If you would like more information please advise.
