The Turbomeca TM 333 represents a turboshaft powerplant engineered by the French company Turbomeca specifically for helicopters within the 4 to 5 tonne weight category. Its initial test run occurred in August 1981, with commercial deployment commencing during the mid-1980s. This engine marked Turbomeca’s inaugural incorporation of a single-stage turbine, enabling a more streamlined and compact configuration. Originally, it was rated for 750 continuous horsepower, but it was engineered with scalability in mind, culminating in the later 2B2 variant capable of producing up to 1,100 horsepower.
