Title: The Innovations of Sébastien Tajan
Introduction
Sébastien Tajan is a notable inventor based in Sucy en Brie, France. He has made significant contributions to the field of turbomachinery, particularly in the design and functionality of propellers. With a total of 2 patents to his name, Tajan's work showcases his innovative approach to engineering challenges.
Latest Patents
One of Tajan's latest patents is a propeller comprising a moveable dynamic scoop. The main purpose of this invention is to enhance the efficiency of a turbomachine by incorporating a propeller with a plurality of blades and a blade support ring. This design features housings that hold pivots supporting the roots of the blades. Notably, at least one of the pivots is associated with a dynamic scoop that can move between distinct positions. In the open position, it captures cooling airflow, while in the closed position, it adjusts based on the orientation of the corresponding blade.
Another significant patent is a system for controlling the pitch of the propeller blades of a turbomachine. This control system includes a power actuator that is coaxial with the axis of rotation of the propeller. A transmission device connects the power actuator to the pivots of the blades, which are arranged radially with respect to the axis of rotation. The actuator is a rotary jack, and its mobile part rotates about the axis of rotation, transforming the rotation into a movement of the blades about their respective pivot axes.
