Latest Patents

Stefan Irmisch's latest patents include two groundbreaking inventions. The first patent describes a **Rotating Machine**, which is cooled by a unique cooling medium directed through the machine in both a main flow and a secondary flow. This innovative design integrates a rotor and a stator with a swirl passage, effectively guiding the secondary flow to be discharged from a pre-swirl nozzle. A notable feature is a control device that employs a shape-memory alloy, automatically managing the secondary flow based on temperature variations.

The second patent focuses on a **Sealing Arrangement for a Thermal Machine**. This invention addresses the issue of sealing gaps between adjacent thermally loaded components within a thermal machine, particularly turbomachines or gas turbines. The design integrates a seal supported in a recess that extends transversely across the gap. What's remarkable about this seal is that it is partially formed from a shape-memory alloy, enabling it to alter its sealing behavior when specific temperature limits are surpassed.
