NASA Convair 990

The Convair 990 Coronado was a jet airliner produced by the Convair division of General Dynamics, a "stretched" version of their earlier Convair 880 produced in response to a request from American Airlines. The 990 was lengthened by 10 feet, which increased the passengers from between 88 and 110 in the 880, to between 96 and 121 (depending on the interior). This was still considerably smaller than the contemporary Boeing 707 (110 to 189) or Douglas DC-8 (105 to 173), although the 990 remained some 25 to 35mph faster than either in cruise.

The 990 entered production in 1961. One interesting change compared to the 880 was the addition of large bulges on the upper wing, in order to increase the plane's wings critical Mach and reduce transonic drag. This allowed the heavier 990 to gain a small amount of speed over the 880, cruising at about Mach 0.91. Originally, there were plans to use the bulges as fuel tanks, but during test flights, the extra weight caused the tanks to vibrate excessively. Instead the inner set of bumps also served a secondary role as fuel dump for the fuel tanks in the fuselage. The engines were also changed to the uprated General Electric CJ-805-23s, which were unique in that they used a fan stage at the rear of the engine in addition to the small one found in the original 805-3's. Like the 880, 990s were later modified with a "raceway" added to the top of fuselage to hold the wiring for additional instrumentation.

The 990's engine, the CJ-805, was a simplified civilian version of the J79, used in military fighters. Like the J79, the CJ-805 was very smokey. Although other early jet airliners were smokey, the 990 is especially remembered for it. There are stories of people calling fire departments after seeing a 990 fly over to report seeing an airplane on fire. Indeed, when viewed from an airport, where the point of view was looking the long way through the smoke trail, a 990 on final approach looked as if it were burning.

Convair - Wikipedia, the free encyclopedia (173 words)
The Consolidated Vultee Aircraft Corporation, commonly known as Convair, was the result of a 1943 merger between Consolidated Aircraft and Vultee Aircraft, resulting in a leading aircraft manufacturer of the United States.
In March 1953, Convair was acquired by General Dynamics, becoming the Convair Division of the merged company.
Convair also developed Charactron tubes, which were precursors to modern CRT monitors.
The Convair 880/990 Aircraft Information (959 words)
At first, Convair 880 would use the Pratt and Whitney J57 but they were rejected and the aircraft decided to use the General Electric CJ-805, a civil version of the military engine J79 which was placed at the Convair B-58 Hustler.
It was then that Convair made another mistake by promising to American Airlines to develop an improved version of 880 for an order of 25 aircrafts, the Model 30 (Convair 990).
Only 35 Convair 990 were constructed (including aircrafts that were not delivered) and the last commercial flight of the type was done in 1987.
