Title: A Spotlight on Ingo H J Jahn: Innovator and Patentee

Introduction: Ingo H J Jahn is a notable inventor based in Queensland, Australia, recognized for his contributions to sealing technology. With a total of five patents under his name, Jahn has demonstrated a significant commitment to innovation that enhances the efficiency and reliability of various mechanical systems.

Latest Patents: Among Ingo H J Jahn's latest inventions are two groundbreaking patents that focus on sealing elements. The first patent, titled "Sealing Element," introduces a unique sealing element designed for air-riding seal systems. This innovative seal features a mounting portion for attachment to a rotor, paired with a sealing portion possessing a sealing face intended to interface with a second sealing element. A distinctive bridging portion, which extends radially between the mounting and sealing portions, facilitates both axial and angular displacement, enabling optimal performance through a pliable or flexible membrane structure.

The second patent, referred to as the "Sealing Arrangement," is aimed at improving intershaft seals in gas turbine engines. This arrangement includes an air-riding sealing ring positioned between runners. It cleverly utilizes a buffer fluid—such as air—delivered to a buffer cavity via a passage in the sealing ring. This mechanism creates a positive pressure drop along fluid-riding gaps, effectively preventing leakage across the sealing arrangement. Notably, the design incorporates a split carbon ring, with measures to minimize buffer air leakage at the split.
