Examination of the fuel supply system of a naval gas turbine in operation

Abstract

Preliminary results are presented of fuel consumption measurements in a naval multishaft gas turbine. The main aim of the examination was to evaluate the relationship between fuel mass flow and pressure drop at two- passage fuel injectors. The results are used to verify values of the fuel outflow coefficient applied to an injector mathematical model, as well as to check a method, under development, for diagnosing the fuel supply system of the engine in service conditions.
