The J33 was a US-produced development of Frank Whittle's early Rolls-Royce Derwent, enlarged to produce dramatically more thrust, starting at 4,000 lbf and ending at 4,600 lbf with an additional low-altitude boost to 5,400 lbf with water-alcohol injection. Frank Whittle speaking to employees of NASA Glenn Research Center, USA, in 1946 Sir Frank Whittle, OM (June 1, 1907 - August 9, 1996) was a Royal Air Force officer who invented the jet engine. ... The Derwent was the second jet engine design to be put into production by Rolls-Royce. ...

The J33 was originally developed by General Electric as part of their work with Whittle's designs during World War II. Their first engine was known as the I-A, but after minor changes to adapt it to US production, it started limited production as the I-16 in 1942, the 16 referring to its 1,600 lbf thrust. Full production started as the J31 when the Army Air Force introduced common naming for all their engine projects. The General Electric Company, or GE, NYSE: GE is a multinational technology and services company. ...

Along with the I-16, GE also started work on an enlarged version, known as the I-40. As the name implied, the engine was designed to provide 4,000 lbf. The development cycle was remarkably rapid. Design work started in mid-1943 and the first prototype underwent static testing on January 13, 1944. Stanley Hooker of Rolls was shown the I-40 in 1943 and was startled at how much progress they had made so quickly, and returned to England to quickly design an even larger design, the 5,000 lbf Rolls-Royce Nene. Sir Stanley George Hooker (b. ... The Nene or RB.41, was Rolls-Royces third jet engine to enter production, designed and built in an astonishingly short five month period in 1944, first running on October 27th, 1944. ...

Lockheed was in the midst of the XP-80 project at the time, originally intending to power their design with a US-produced version of the Halford H-1 of about 3,000 lbf. Production of the H-1 ran into delays, and since the I-40 would dramatically improve performance, plans were made to fit the prototypes with the I-40 instead. The Lockheed SR-71, remarkably advanced for its time and unsurpassed in many areas of performance The Lockheed U-2 first flew in 1955 providing much needed intelligence on Soviet bloc countries Lockheed Corporation was an aerospace company founded in 1912 which merged with Martin Marietta in 1995 to form... The Lockheed P-80 Shooting Star was the first operational jet fighter used by the United States Army Air Force. ... The De Havilland Goblin was a turbojet engine. ...

The I-40 became important to the USAAF's plans when the I-16 powered P-59 was skipped over in favour of the I-40 powered P-80 as the US's first production jet fighter. In 1945 the license to actually produce the engine was not given to General Electric, but Allison Engine instead. Allison, working largely from government-owned wartime factories, could produce the engine in quantity more quickly and cheaply. GE was upset about this and complained that in the future they would no longer turn over their work for production. The Bell P-59 was a fighter aircraft built in the United States during World War II. Its prototype, the XP-59 became the first jet-powered aircraft to fly in the US when it took off for the first time on October 1, 1942. ... The Lockheed P-80 Shooting Star was the first operational jet fighter used by the United States Army Air Force. ...

By the time the production lines were shut down Allison had built over 6,600 J33's, and General Electric another 300 (mostly the early runs). In addition to P-80 and its derivatives T-33/TV-2 and F-94A/B, J33 was used in XF-92, MGM-1 Matador, SM-62 Snark, and MGM-13 Mace surface-to-surface guided missiles. The Lockheed P-80 Shooting Star was the first operational jet fighter used by the United States Army Air Force. ... Categories: Aircraft stubs | U.S. military trainer aircraft 1940-1949 ...

Allison Engine Company at AllExperts (913 words)
In 1929, shortly after the death of James Allison, the company was purchased by the Fisher Brothers, who instructed it to use the cylinder design for a six cylinder engine for a "family aircraft".
Allison also started the development of a series of turboprop engines for the U.S. Navy, starting with the T38 and a "twinned" version as the T40.
Allison tried again with the Allison T56, basically an enlarged T38 with the power of the T40, and was eventually rewarded when this engine was selected to power the C-130 Hercules.

The J33 turbojet is a direct descendant of the original British Whittle jet engine developed in the 1940s.
The J33 weighed over 1,700 pounds and generated a maximum of over 5,000 pounds of thrust with water and alcohol injection.
This J33 cutaway was created by the Training Aids department of the Chanute Technical Training Center for use in various jet engine courses.
