Marine Turbine Engines

[edloh]

Yatchjim,

you have described what is commonly known a 2 shaft gas turbine. part A is also known as the gas producer and part B is know as the power turbine. from what i was told, they are usually used with a jet drive. a variable pitch prop as suggseted above is an alternative. the main issue is that the power turbine have limited torque at low speed.
