Industrial RB211-- 15 Years of History and Development

Résumé du livre

The Industrial RB211 was derived from the aero RB211-22B engine in the early 1970's and was first installed at Burstall, Canada in 1974 as a prime mover in the Trans Canada Pipe Lines gas transmission pipeline. The paper opens by tracing the progressive power uprating of the engine since 1974 and then reviews its proven performance retention. The paper continues with a description of some specific requirements of the industrial engine that differ from acre philosophy. A review of the major technical challenges that have been encountered during its development is also undertaken. Most of these problems have been occasioned by the fundamental differences between continuous sea level operation and the relatively short cyclic duty of the aero engine. The paper closes with a brief look at the engineering programme for the aero family of RB211 engines that will provide the technology to further uprate the industrial engine well into the future. The current programme to meet future environmental requirements is declared. The orientation of components discussed in this paper are shown in Fig.l. Aero terminology is also used for the industrial engine so, for example, what would normally be called the low pressure (LP) compressor in a two-shaft machine is referred to as the intermediate pressure (IP) compressor.
