Title: Frederic Beule: Innovator in Turbomachinery
Introduction
Frederic Beule is a notable inventor based in Brunoy, France. He has made significant contributions to the field of turbomachinery, holding 2 patents that showcase his innovative approach to combustion systems.
Latest Patents
One of his latest patents is for a turbomachine annular combustion chamber. This invention features an outer axial wall, an inner axial wall, and a chamber bottom end that connects these walls. The design includes several passages that enable the initiation of cooling air films along the hot inner surfaces of both walls. The outer and inner axial walls are multi-perforated to reinforce these cooling air films. Notably, the upstream part of these walls is equipped with a first zone of perforations that allows cooling air to be introduced inside the combustion chamber in reverse flow.
Another significant patent is an air/fuel injection system that incorporates cold plasma generating means. This system is designed for injecting an air/fuel mixture into a turbomachine combustion chamber. It includes a hollow tubular structure for the flow of the mixture, a fuel injection device at the upstream end, and an air injection device downstream. A cold plasma generator is also included to generate active species in the flow, facilitating the prefragmentation of the air/fuel mixture molecules. The system features a control device for the cold plasma generator that adjusts based on the turbomachine's operational speed.
