Allison T56

Aircraft Engines

The Allison T56 is an American single-shaft, modular military turboprop with a 14-stage axial compressor driven by a four-stage turbine. The Allison Engine Company developed it from the T38 for the Lockheed C-130 Hercules, and it entered production in 1954. It has been a Rolls-Royce product since 1995, when Rolls-Royce bought Allison, and its commercial version is the 501-D. More than 18,000 have been built, logging over 200 million flying hours. Besides the Hercules it powers the Lockheed P-3 Orion, the Grumman E-2 Hawkeye and C-2 Greyhound, and airliners such as the Lockheed Electra. Series upgrades raised power from about 3,460 to over 5,000 shaft horsepower.
