2007 Lockheed L-049 tähtkuju oli Lockheedi tähtkuju lennukiliini esimene mudel. See asus Teise maailmasõja ajal Ameerika Ühendriikide armee õhujõudude jaoks kasutusele sõjaväe transpordilennukina C-69 ja oli esimene tsiviilversioon pärast sõda. Kui tootmine 1946. aastal lõppes, asendati see täiustatud L-649 ja L-749 tähtkujuga.

General Characteristics and Role

The Lockheed L-049 Constellation, often simply called the “Connie,” was the first production model of the famous Constellation family of aircraft. It was a four-engine, pressurized, long-range transport aircraft designed by Lockheed for Trans World Airlines (TWA) in the early 1940s. Its distinctive features—the triple-fin tail and the elegant, dolphin-shaped fuselage—made it an icon of the piston-engine airliner era. Although initially intended for civilian use, all L-049s were pressed into military service during World War II as the C-69 Constellation. Following the war, the C-69s were converted back for commercial service as the L-049, inaugurating the golden age of pressurized, non-stop transatlantic travel.

Powerplant and Performance

  • Engine: 4 x Wright R-3350-B7 Duplex-Cyclone 18-cylinder air-cooled radial engines.
  • Power Output (Each): 2,200 hp (1,640 kW).
  • Maximum Speed: 547 km/h (340 mph).
  • Cruising Speed: 483 km/h (300 mph).
  • Range: Approximately 6,400 km (4,000 mi).
  • Design Note: The R-3350 engines were initially plagued by reliability issues that required substantial engineering efforts to fix before the Constellation could reach its full commercial potential.

Service and Legacy

  • Initial Service: The L-049 was the first Constellation to enter commercial service, beginning with Pan American World Airways and TWA in 1946.
  • Pressurization: It was one of the first successful airliners with a pressurized cabin, allowing it to fly higher than weather disturbances, providing a smoother ride and reducing travel time.
  • Evolution: The L-049 set the stage for later, more advanced variants like the L-649, L-749, and the final, stretched L-1049 Super Constellation.
  • Transatlantic Pioneer: Along with the Douglas DC-4, the L-049 Constellation played a key role in making commercial long-haul and transatlantic air travel routine and comfortable in the immediate post-war period.
