Convair 880 - Design and Development

Design and Development

Convair began development of a medium-range commercial jet in April 1956, to compete with announced products from Boeing and Douglas. Initially the design was called the Skylark but the name was later changed to the Golden Arrow, then Convair 600 and then finally the 880, both numbers referring to its top speed of 600 mph (970 km/h) or 880 ft/s (268 m/s). It was powered by General Electric CJ-805-3 turbojets, a civilian version of the J79 which powered the F-104 Starfighter and F-4 Phantom.

The first example of the initial production version, the Model 22, made its maiden flight on January 27, 1959; there was no prototype. After production started the FAA mandated additional instrumentation, which Convair added by placing a "raceway" hump on the top of the fuselage, rather than ripping apart the interiors over the wing area. The final assembly of the 880 and 990 took place at the Convair facilities in San Diego, California.

The airliner never became widely used and the production line shut down after only three years. The 880's five-abreast seating made it unattractive to airlines, while Boeing was able to out-compete it with the Boeing 720, which could be sold much more cheaply as it was a minimal modification of the existing 707. In addition, the General Electric engines had a higher specific fuel consumption than the Boeing's Pratt & Whitney JT3Cs.

General Dynamics lost around $185 million over the lifetime of the project, although some sources estimate much higher losses. It is generally agreed that the losses incurred in the Convair 880/990 were the largest losses incurred by a corporation up to that time. The aircraft was involved in 17 accidents and five hijackings.

A modified version of the 880 became the Convair 990 Coronado, produced in parallel between 1961 and 1963.
