Lockheed Constellation


Edit

1. - Development

The Constellation's wing design was close to that of the P-38 Lightning, differing mostly in scale. The distinctive triple tail kept the aircraft's overall height low enough to fit in existing hangars, while new features included hydraulically-boosted controls and a thermal de-icing system used on wing and tail leading edges. The plane had a top speed of over 340 mph (547 km/h), a cruise speed of 300 mph (483 km/h), and a service ceiling of 24,000 ft (7,315 m).

According to Anthony Sampson in Empires of the Sky, the intricate design may have been undertaken by Lockheed, but the concept, shape, capabilities, appearance and ethos of the Constellation were driven by Hughes' intercession during the design process.
