Vintage Pacific Airlines/Rolls-Royce Dart F-27 Cutaway Demonstration Engine
1950s - 1960s; Rolls-Royce Motor Cars Ltd. - West Sussex, England
Large educational cutaway model illustrating the operation of the Rolls-Royce Dart turboprop engine used in the Fairchild F-27 airliner. The silver-finished engine nacelle incorporates a broad transparent viewport revealing a central shaft, compressor stages, turbine stages, combustion chambers, fuel-supply system, and color-coded airflow passages. Clearly printed labels identify the "AIR INTAKE," "COMPRESSORS," "FUEL SUPPLY," "TURBINES," and "COMBUSTION CHAMBER."
The engine is fitted with a freely turning four-blade propeller and supported above a beveled wooden base by two chromed metal uprights. A detailed plaque explains the compression, combustion, turbine, reduction-gearing, and propeller-drive sequence. A second plaque reads, "THE ROLLS-ROYCE DART PROP-JET POWERS THE FAIRCHILD F27 OPERATED BY PACIFIC AIRLINES." A push-button control and concealed wiring remain present, although the electrical demonstration function has not been verified.
Rolls-Royce introduced the Dart to commercial aviation during the early 1950s, helping establish the turboprop as a practical powerplant for passenger aircraft. Pacific Airlines ordered six Rolls-Royce-powered Fairchild F-27s and placed its first three into revenue service on April 26, 1959.
Item is in good condition; the base shows edge wear, one chip, and scattered scratches. The explanatory lettering remains crisp and complete, while the small Rolls-Royce logo on the engine exhibits deterioration. The plastic viewing port has a few light scratches, and the propeller turns freely. The underside of the engine displays a series of black marks. The underside of the base is inscribed "368" and "PAC." Electrical operation has not been tested.
