Title: Innovations of Robert J Hemmelgarn

Introduction

Robert J Hemmelgarn is a notable inventor based in Mason, OH (US). He holds a total of 6 patents that showcase his contributions to the field of turbomachinery, particularly in turbofan engine technology. His innovative designs have significantly impacted the efficiency and safety of engine operations.

Latest Patents

One of his latest patents is the "Fan case for turbofan engine having a fan decoupler." This invention features a fan case that includes a plurality of fan blades mounted to a rotor disk. The decoupler is designed to fail in response to a predetermined load, ensuring safety during operation. The fan case comprises a substantially annular shell with a forward section, an intermediate section, and an aft section. The design includes an aft-facing step at the forward end of the intermediate section to prevent blade fragments from being ejected forward. This innovative structure allows the fan to orbit when the decoupler fails, while also directing blade fragments aft to avoid secondary damage.

Another significant patent is the "Contoured hardwall containment," which presents an improved containment structure for turbomachinery. This casing features at least one impact-resistant section that is thick enough to resist piercing upon impact by a blade. The smoothly contoured thickness along its axial length minimizes the risk of local failure in the event of an impact, enhancing the overall safety of the engine.
