Abstract

The aim of this project was to determine the feasibility of operating gas turbines on liquid hydrogen fuel. Following a literature survey to determine the state of the art, project work commenced in several areas which showed promise for achieving the optimum use of the hydrogen properties. These included analysis of suitable burner and combustion chamber designs, heat exchange systems to allow cooling of turbine cooling air and recuperation of exhaust heat into the fuel, and the suitability of current air cooled turbine components for use with cooled cooling air supplies. A computer program was developed to calculate accurately the performance of engines with complex heat exchange arrangements, fuelled with cryogenic fuels. The data obtained were used to optimize the use of hydrogen fuel in two engines of current design, and to evaluate the performance of these and other engine cycles using hydrogen. The design rules for control systems for such engines were outlined, and the requirements for hardware development were defined.
