Title: Helmut A. Geidel: Turbofan and Propfan Engine Innovations.
Introduction
Helmut A. Geidel is an inventor based in Karlsfeld, Germany, whose patent work focuses on gas turbine and aircraft engine technologies. His inventions address the design and operation of turbofan and propfan engines.
Latest Patents
Geidel’s listed patents include two engine-related inventions:
- **Turbofan engine having a contrarotating low-pressure compressor.** This design uses oppositely rotating fan rotors and a booster with two coaxial, contra-rotating rotors. Its gearless arrangement is intended to distribute loading more uniformly across the low-pressure shafts.
- **Propfan turbine engine.** This invention provides a dedicated lubrication system for the reduction gearing that drives the propfan rotors. The system is arranged between the gas turbine and the gearing, with cooling air supplied in a way designed to avoid disrupting airflow to the gas turbine compressor.
