Abstract

An apparatus and method for active gap monitoring for a continuous flow machine, in particular an aircraft propulsion device, which has a rotor and a housing which surrounds the rotor forming a rotor gap, is disclosed. The apparatus having a cooling channel which is arranged on the external circumference of the rotor housing and is supplied with cooling air from a plenum. The cross section of the cooling channel decreases from the plenum in the circumferential direction. This ensures homogenous cooling and reduces the weight of the apparatus.
