Title: The Innovations of Ernst C. Schellhase
Introduction
Ernst C. Schellhase, an inventor based in Fort Worth, TX, has made significant contributions to engineering with a total of 12 patents. His innovative spirit and technical prowess have paved the way for advanced designs in the field of rotor dynamics, especially in applications related to helicopters.
Latest Patents
One of Schellhase's latest patents is the dual spring rate damper, which is a sophisticated rotor hub designed to enhance the performance of rotor blades during flight. This innovation features a central member that is rotatably coupled to a rotor mast, along with a blade grip that is rigidly attached to the rotor blade and movably coupled to the central member. The adjustable damper plays a vital role by damping the force exerted on the rotor hub, while selectively allowing for adjustments between a first and a second spring rate.
Another significant patent under his name describes a damper with a piston that incorporates elastomeric seals. These seals are in sealing contact with the piston and restrict movement to a specified path along its axis. The design cleverly utilizes fluid chambers to enhance damping, ensuring that movement of the piston can be resisted by varying spring rates depending on fluid flow conditions.
Career Highlights
Schellhase has worked with notable companies in the aerospace industry, including Bell Helicopter Textron Inc. and Textron Innovations Inc. His tenure at these organizations allowed him to apply his extensive knowledge in the development of innovative rotor systems, further solidifying his reputation as a leading inventor in the field.
