DEVELOPMENT OF HARDWARE SIMULATOR FOR ROTOR SPEED AND PULSE WIDTH MODULATED SIGNALS IN GAS TURBINE SYSTEMS

Abstract

Gas turbine engines are widely spread in aviation, therefore their research is an important field of industry. The application range is very wide, from the giant turbofans of commercial airliners to the micro turbojet engines of hobbyist usage. Rotor speed is a key parameter in power management, indication and control, used in a vast majority of gas turbine systems. Control signals can also include pulse width modulation, among discrete or other analogue forms. The aim of this paper is to describe the development of a small simulation hardware that is intended to generate variable rotor speed and pulse width modulated signals for control or indicating system research, development, or diagnostics.
