Abstract: Brayton cycles are open gas turbine cycles extensively used in civil aviation and the petrochemical industry because of their advantageous volume and weight characteristics. Given the bulk of engine emissions associated with them, it is necessary to promote their environmental friendliness, including regular sound technical performance. This research examines high-bypass, lowspecific-power plants in aviation and aero-derivative gas turbines for combined heat and power generation in the petrochemical industry. The investigation encompasses the comparative assessment of simple and advanced gas turbine cycle options, including the component behaviour of the systems. This comprises the performance module. The research has contributed to understanding the technical performance of advanced and straightforward cycle helicopter engines, as well as aero-derivative industrial gas turbine cycles, at both design and off-design conditions. The simple cycles were modified to improve fuel burn and thermal efficiency by incorporating additional components, resulting in the advanced cycles. The helicopter engine investigated was converted to a small-scale aero-derivative industrial engine. Modelling the combined heat and power performance of small, medium, and large-scale aero-derivative industrial gas turbines was also implemented. The contribution also includes understanding the technical performance of both simple and advanced aero-derivative gas turbines, as well as combined heat and power systems, at both design and off-design conditions. A case study underlies the development and deployment of this model. The novelty lies in the conception of a tool for predicting the most preferred simple and advanced cycle aero-derivative engines, as well as combined heat-and-power generation in the petrochemical industry, and the derivation of advanced and straightforward cycle small-scale aero-derivative industrial gas turbines from helicopter engines.
