Were Convair 880s That Smokey?

Sun Mar 04, 2001 9:24 pm

Is this the normal smoke of the engines or just an effect from B&W photograph? If it is, how were these planes allowed to fly?!!!

Yes, that was in sixties and seventies. Early 707/720 has about similiar to this before they re-engines. They were water-injected engines that make alot of smokes on the take-off. Thus that why they no longer in service nowday.

Ah. the good old days when jetliners were pure jets & real men flew them...not automation like today. Just an afterthought here...Some DC-8-60s still in service, still smokes a little, but not nearly like the Convair in the photos here. Regards.

The first generation of airliners were real jets! I miss their scream.

Indeed they were that smokey. The Convair 880 used an early General Electric turbojet engine called the CJ-805-3, which was not a water injection augmented engine. This engine was the powerplant that was featured on the Convair B-58 Hustler bomber as well.

Convair was quite smart using this engine (the PW JT3C was offered as an option I might add but none were taken up using it). Convair made vast use of the experience and technology used in military programs into civil ones like the CV-880 and 990. The "Scotchweld" feature on the CV-880 was developed by today's 3M Corporation, was used extensively in Convair's F-102 fighter program, this provided for sealed wing fuel tanks. Another feature developed on the F-102 was the use of hot bleed air from the engines to keep the cockpit windshield clear of rain or ice (no need for windshield wipers-take a close look at any CV-880/990 and you wont see them there (G).

These airplanes were known for their rugged construction, durability, speed and toughness. Clint Groves; owner of ATP Airliners America (decal and airline model retailer in the San Jose, CA area) and retired from TWA, wrote in his book "Jetliners", that the CV-880 was built like a "tank" and definitely the airplane you wanted to be aboard penetrating a line of tornado producing thunderstorms over the Midwest. (Imagine that (Grin)

Their weak side was their seemingly "over-complicated" nature of onboard systems for that time that made them maintenance nightmares. (G) Too bad they didnt sell as well as their competitors, they were truly ahead of their time. I suggest a read of Jon Proctor's "Convair 880 & 990" book available by World Transport Press. It's an excellent resource on these great airplanes.
