description The present invention relates to a micro gas turbine engine provided with an active tip clearance control. In a micro gas turbine engine, a capacitive sensor is used for measuring a tip clearance of a radial compressor section thereof, and an actuator is used for axially displacing a rotor shaft in response to an output from the capacitive sensor. Because the capacitive change gives an accurate measure of the size of the tip clearance, a particularly high sensitivity can be achieved in parts where the tip clearance is small, thereby providing a highly precise tip clearance control.
