[according to whom?] In addition to the casting revisions that result in a physically larger carburetor, the primary metering rod length is different from '74 and older Q-Jets.
The CCC system included the electronic Rochester 4-bbl E4ME Quadra-Jet, with computer-adjusted fuel metering on the primary venturis and a throttle position sensor allowing the CCC to calculate engine load. In the ignition system, CCC was fully responsible for the timing curve; mechanical and vacuum advances were eliminated from the distributor.
This need extended into the beginning of the Jet Age, and combined with the limited thrust available from early jet engines, it was most practical to design large jet airliners with four engines. [ 4 ] [ 22 ] The first commercial jet aircraft was the four-engined De Havilland Comet , which first flew in 1949. [ 1 ]
For commercial jet aircraft the jet noise has reduced from the turbojet through bypass engines to turbofans as a result of a progressive reduction in propelling jet velocities. For example, the JT8D, a bypass engine, has a jet velocity of 400 m/s (1,450 ft/s) whereas the JT9D, a turbofan, has jet velocities of 300 m/s (885 ft/s) (cold) and 400 ...
True to form, Kylie kept it real, adding, “I still can't believe that people think that women who are building a human being want to hear anything about their size. Newsflash, they don't. Cut ...
The Cessna Citation is a family of business jets manufactured by Cessna that entered service in 1972. [1] In the fifty years following the type's first flight in 1969, more than 7,500 Citations were delivered, forming the largest business jet fleet in the world. [2] Deliveries reached 8,000 by 2022, while logging over 41 million flight hours. [3]
