The Turbomeca TM 333 is a turboshaft engine manufactured by French company Turbomeca and designed for helicopters weighing 4-5 tonnes.[1] It first ran in August 1981 and was introduced commercially in the mid-1980s.[1] It was the first Turbomeca engine to use a single stage turbine, making it more compact than its predecessors.[1] In its original design, the engine was rated at 750 continuous horsepower, though it was designed to allow for future power increases,[1] and the later 2B2 variant made 1,100 horsepower.[2]
