05/31/2010. First commercial transport certificated with Turbo-Compound engines, the Model 1049C was developed to correct the basic shortcomings of the original Model 1049, insufficient power resulting in performance lower than that of the Douglas DC-6B, by taking advantage of the new powerplant developed by the Wright Aeronautical Division of Curtiss-Wright.

Adding to the basic Double Cyclone engine three 'blow-down' turbines, which converted the heat energy of exhaust gases into additional power, the Turbo-Cyclone offered a twenty per cent reduction in fuel consumption. In its
872TC-18DA-1 version as fitted to the Model 1049C, this engine was rated at 3,250 hp for take-off and markedly improved performance. Take-off gross weight and maximum landing weight were respectively increased to 133,000 lb (60,328 kg) and 110,000 lb (49,895 kg).

The first Turbo-Cyclone powered Super Constellation, the pictured PH-TFP, began flight trials on 17 February, 1953, three months before the similarly-powered Douglas DC-7. Lockheed produced a total of 48 Model 1049Cs, for delivery between June 1953 and June 1954 to Air France (ten), Air-India (two), Eastern (sixteen), KLM (nine), PIA (three), Qantas (three), and TCA (five).

PH-TFP was registered in the Netherlands on December 20, 1953, was reregistered as PH-LKP on March 8, 1954 and in 1956 the designation was altered to a Model 1049E. On June 22, 1965, the aircraft was deregistered as "scrapped and sold in parts".
