Title: Donald C. Moringiello and Rotor-Damping Inventions

Introduction

Donald C. Moringiello is an inventor associated with Windsor, Connecticut, and United Technologies Corporation. His patent work includes damping systems designed to manage vibration in gas turbine engines and their rotor-supporting bearings. He is credited with 3 patents.

Latest Patents

Moringiello’s listed inventions include a viscous/friction damper and a friction damper. The viscous/friction damper combines a friction damper in series with a viscous damper to address both ordinary vibration and stronger vibration caused by a larger imbalance in a jet-engine rotor, such as one resulting from a bowed rotor. A loading spring helps recenter the friction damper after the stronger vibrations subside.

The friction damper concerns bearings that support gas-turbine-engine rotors. It uses frictionally juxtaposed discs supported by a spring arranged in parallel with the discs.

Career Highlights

Moringiello’s listed patent contributions focus on controlling rotor vibration through mechanical damping arrangements. These designs address vibration conditions that can vary in magnitude, supporting the operation of gas turbine engine components.

Collaborations

Moringiello’s listed coworkers include David H. Hibner and Nils G. Carlson. His work is associated with United Technologies Corporation.

Conclusion

Donald C. Moringiello’s patent record highlights engineering approaches to rotor and bearing vibration control, including systems that combine frictional and viscous damping.
