Design and Development
Designed by John Knudsen Northrop and Gerrard Vultee, both of whom would later form their own companies, the plane was originally intended to serve with Lockheed's own airline routes. They set out to build a four-seat aircraft that was not only rugged, but the fastest aircraft as well. Utilizing the latest designs in monocoque fuselages, cantilever wings and the best engine available, the Vega delivered on the promise of speed.
The fuselage was monocoque, built from sheets of plywood, skinned over wooden ribs. Using a large concrete mold, a single half of the fuselage shell was laminated in sections with glue and then a rubber bladder was lowered into the mold and inflated with air to compress the lamination into shape. Two fuselage halves were then nailed and glued over a previously made rib framework. With the fuselage constructed in this fashion, the wing spar had to be kept clear, so they decided to make a single spar cantilever mounted on the very top of the aircraft. The only part of the aircraft that wasn't particularly streamlined was the landing gear although production versions wore sleek "spats". For power they chose the Wright Whirlwind, which delivered 225 horsepower (168 kW).

Famous quotes containing the words design and/or development:
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
