The Lockheed L-188 Electra is an American turboprop airliner built by Lockheed.First flown in 1957, it was the first large turboprop airliner built in the United States. With its fairly high power-to-weight ratio, huge propellers and very short wings (resulting in the majority of the wingspan being enveloped in propwash), large Fowler flaps which significantly increased effective wing area ...
Like the earlier 2-0-2, the 4-0-4 was a cantilever monoplane with a standard tail unit (cantilever tailplane and single vertical stabilizer). It had an airstair in the lower tail section for passenger boarding and disembarkation, retractable tricycle landing gear and was powered by two Pratt & Whitney R-2800-CB16 radial piston engines.
The Canadair North Star is a 1940s Canadian development, for Trans-Canada Air Lines (TCA), of the Douglas DC-4. [1] Instead of radial piston engines used by the Douglas design, Canadair used Rolls-Royce Merlin V12 engines to achieve a higher cruising speed of 325 mph (523 km/h) [2] compared with the 246 mph (396 km/h) of the standard DC-4.
