Rolls-Royce Nene

The Rolls- Royce Nene or Rolls -Royce RB.41 was to the specimens Welland and Derwent, the third jet engine of the British company Rolls- Royce, which was built in series. The engine with radial compressor in 1944 designed and built in just five and a half months and completed the first test runs on 27 October 1944. Has been used in a few British aircraft types such as the Hawker Sea Hawk and Supermarine Attacker and soon from Avon engine with axial compressor replaced.

The U.S. Taylor Turbine Corporation built the engine as the J42 - TT -2 under license. Several of the early U.S. carrier aircraft such as the Grumman F9F Panther were equipped with this engine. Later the license to Pratt and Whitney was sold, a version developed in conjunction with Rolls- Royce with water injection, the J- 48th 25 engines, including the construction plans of the Soviet Union were passed as a sign of good will after in July 1946, a Soviet delegation, among others, Artyom Mikoyan, had visited at the invitation of the British Government, the Rolls- Royce engine production.

The engines were used in prototypes, then it came to the mass production of clones such as the Klimov RD -45 and the more powerful Klimov WK -1, which were used in a number of Soviet fighter aircraft, although there was no license agreement with Rolls- Royce. For example, in the MiG -15, the one-time best fighter in the world. The engine was built in France, China and Australia under license. In Australia, so the De Havilland Vampire of the RAAF was equipped.

Although it was a direct development from the work of Frank Whittle, a centrifugal compressor with two inlets for improved compression rate and thus higher thrust force was used in the Nene. It had a single-stage axial turbine combustors and nine and weighed 750 kilograms. During the construction phase Rolls- Royce decided to give its engines both numbers and names, with the Welland and Derwent retained their original numbers of Rover, B/23 and B/26. Later, it was thought that these numbers would be too reminiscent of bombers and completed the "R" of "Rolls ", so the " RB " numbers still used today originated.

The Nene reached about 22 kN twice the thrust of the engines of the previous generation, and that with similar dimensions and basic design. It would have been quite possible to replace the older engines by Nene. Due to the age of the Gloster Meteor saw no need for further improvement. Instead, a series considerably more powerful engines was driven based on the Rolls- Royce Avon. Centrifugal compressor engines such as Nene ran out after that.

The Nene powered the first civil jet aircraft, a modified Vickers Viking, which first flew on 6 April 1948.

The Nene was named after the East Anglian river.
