With a total of 2 patents, his work reflects a commitment to advancing technology in this area.

Latest Patents

Hess's latest patents include innovative designs for rotor systems in turbogenerators. One of his patents focuses on a rotor of a turbogenerator that incorporates direct gas cooling with a two-stage flow cascade. This design features an air-cooled electrical machine that utilizes reverse cooling in a closed circuit. The two-stage blade cascade optimizes the incident flow of cooling air to both the rotor and the rotor winding. The first stage acts as a deceleration cascade with pressure-generating properties, while the second stage serves as a deceleration cascade with deflecting properties.

Another significant patent by Hess pertains to a turbo-generator that includes a rotor and a stator concentrically surrounding the rotor. This design features a cooling arrangement where a main fan draws in a gaseous cooling medium. The cooling medium flows through passages in both the rotor and stator, enhancing rotor cooling by directing the heated medium radially outward from the air gap through outflow passages in the stator.
