Lockheed 10 Electra

Lockheed's first all-metal aircraft, the Electra was 10-passenger transport featuring twin engines and a twin-rudder tail. It was adopted in 1934 by Northwest Airlines, followed by eight more American passenger lines. The plane was exported to Argentina, Australia, Chile, Columbia, Japan, New Zealand, Poland, Romania, USSR, UK, Venezuela and Yugoslavia. As a military transport, it saw service during the Spanish Civil War, and in WWII with the RAF, USAF, and the Royal Canadian Air Force. The most common version was the 10-A, with 101 examples built.

The Electra had a crew of two: pilot and co-pilot. The plane had a historical range of 810 miles. The plane uses 33.6 gallons of aviation fuel per hour at routine usage. A full load of fuel costs $52.

Design Notes:

Historical wing area was 458 sf. Design aSpeed was 190 mph. Historical values for wing area and loaded weight were used for performance calculations. Design loaded weight was lowered 14% to the historical; design payload was reduced 244 lbs. to the historical value as well. The design purchases a 270-gallon fuel tank; the historical capacity is shown.
