The research is motivated by the need to study load accepting and load rejection characteristics of cooperating gas turbines. Only overall performance parameters of the gas turbine are provided by the manufacture and that made it difficult to carry out such studies. This work proposes the use of scaling method in the fixed geometry region and stage-stacking method in the variable geometry region. Generalized stage and overall component performance curves, all from literature, are used in presenting the performance maps. Characteristics of compressors whose actual maps are known are first used to choose a reference map. Relying on the selected map, predicted performance curves are obtained for the aforesaid gas turbine. The variable geometry is demonstrated considering actual data from literature. Having the design point parameters from limited overall performance data, the proposed approach has managed to get the key performance maps. The results can be used for stability, performance optimization and condition monitoring studies. © Asian Network for Science Information. date: 2011 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-79955554479&doi=10.3923%2fjas.2011.1885.1894&partnerID=40&md5=fd7330630e23c0d7ed0499a40eb7cf3f id_number: 10.3923/jas.2011.1885.1894 full_text_status: none publication: Journal of Applied Sciences volume: 11 number: 11 pagerange: 1885-1894 refereed: TRUE issn: 18125654 citation: Tamiru, A.L. and Hashim, F.M. and Rangkuti, C.
