The ultimate in turboprop technology, the T-4650 is a stock turboprop that produces ≈4650 kN of thrust. The T-4650 is also highly efficient, with a specific impulse of over 27000s. This engine comes from a (relatively) long line of turboprops created partly to help me learn the ins and outs of turboprop technology, but mainly for different purpose. This is probably the last turboprop that I will make, atleast for a while.
