The paper presents an experimental research and a particular operation mode of testing, for an industrial application. The application refers to one stage axial gas free power turbine, run by the gases provided from two gas generators of TV2-117A turboshaft engines. By running the free power turbine is analysed the starting and idle mode of TV2-117A modified engines and of free turbine. After the analysing, the major interest is how to be operated on higher modes than idle. To modify the TV2-117A turboshaft engine into an only gas generator, the free power assembly module was removed from the engine and the gas flow was delivered into one turbine. Also the conversion of TV2-117 turboshaft engine into a gas generator involves a modification into the engine fuel control. The gases from both the engines flow to an only one gas turbine and the turbine produces shaft power. The testing of the free power turbine is performed on the test bench by using a dynamometer and an operating system. For both, we use an acquisition system and a programmable controller using an operating sequence. The operating sequence is based on parameters and commands, used to control and monitor the engine. The free power turbine is designed to run a natural gas compressor for industrial application and at sea level conditions it develops a power of 2600 kW at a speed of 15000 rpm. The contribution of this paper is the study of behaviour of every engine and the free power turbine at start-up and for the idle mode.
