Lockheed L-1049 Super Constellation
The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. The L-1049 was Lockheed’s response to the successful Douglas DC-6 airliner, first flying in 1950. The aircraft was also produced for both the United States Navy and Air Force as transport, electronics, and airborne early warning and control aircraft.
In 1950 Lockheed had repurchased the XC-69 Constellation prototype from the Hughes Tool Company. The XC-69 however, was equipped with four Pratt & Whitney R-2800 radial engines instead of the Wright R-3350s used on production models (Lockheed had made that installation on the prototype to test the R-2800 as a possible engine option for the L-049). Lockheed lengthened XC-69 by 18 feet (5.5 m), to become the basis for the L-1049 Super Constellation. The aircraft first flew later that year still fitted with R-2800 engines. Later R-3350 956-C18CA-1 engines with jet stacks increased thrust. Later modifications included strengthened landing gear and larger vertical stabilizers. Eastern Air Lines ordered 10 aircraft, while Trans World Airlines (TWA) followed with an order for 14. The L-1049 had some 550 improvements and modifications compared to the L-749, including greater fuel capacity, rectangular windows, larger cockpit windshields and improved heating and pressurization.
R-3350 Turbo-compounds made in 1953 became available for civil use. Lockheed incorporated them into the L-1049C, which first flew on February 17 of that year. The R-3350-972-TC18DA-1 turbo-compound engines on the L-1049C had a new turbine system, the Power Recovery Turbines (PRT). Each engine’s exhaust gas flowed through three turbines, increasing power by 550 hp (410 kW).
One drawback of the PRT was the visible flame from the exhaust pipes. Armor plating 2 in (5.08 cm) thick placed under the stack solved this problem. The L-1049C had a higher cruising speed and climb rate. Although lacking the range of the DC-6B, the L-1049C had identical performance to the Douglas and could carry a larger payload. The new model features a strengthened wing, cabin soundproofing, and landing gear retraction system.
