Allison T56-A-1 (501-D13) Turboprop Engine, Cutaway, Motorized

Allison T56-A-1 (501-D13) Turboprop Engine, Cutaway, Motorized

     

In 1951, the U.S. Air Force announced a requirement for a medium-size logistic and tactical transport aircraft, which resulted in the workhorse Lockheed C-130 Hercules. With support of the Air Force, Allison designed the T56 turboprop for the C-130, and first flight-tested the engine in 1954 in the nose of a Boeing B-17 testbed aircraft. The first production installation was on the Lockheed YC-130, which first flew on August 23, 1954.

The engine displayed here, a T56-A-1 first-generation (Series I) military model, powered the Lockheed C-130A and Convair YC-131C Samaritan. Its commercial equivalent, the 501-D13, powered airliners including the Lockheed Electra L-188, which entered commercial service with Eastern Airlines in January 1959. This highly successful turboprop has powered several other large military and commercial aircraft, such as the Lockheed P-3 Orion, Grumman C-2 Greyhound and E-2 Hawkeye, and Aerospace Lines Super Guppy aircraft.
