Title: Innovations by Jean-François Allias in Electrical Propulsion Systems
Introduction
Jean-François Allias is a notable inventor based in Toulouse, France. He has made significant contributions to the field of electrical propulsion systems, holding a total of 5 patents. His work focuses on enhancing the efficiency and functionality of aircraft propulsion systems.
Latest Patents
One of Allias's latest patents is an electrical propulsion system that includes a plurality of electric motors coupled to the same input shaft of a transmission system. This innovative design features an aircraft that incorporates at least one such electrical propulsion assembly. The assembly consists of a propeller with a rotation axis, at least two electric motors offset in a longitudinal direction parallel to the propeller's rotation axis, and a main drive shaft that is parallel to the propeller's rotation axis. The transmission system includes an output shaft connected to the propeller and an input shaft connected to the main drive shaft.
Another significant patent is for a propulsive electric motor set with an electric generator. This system is designed for aircraft and includes an electrical energy source and an electric motor equipped with a drive shaft on which a propeller is mounted. The electric motor features a first set of windings linked to the electrical energy source to provide rotational drive for the drive shaft. Additionally, a second set of windings is included, which, when the drive shaft is powered by the first set of windings, provides an electric generation function. This allows the aircraft's non-propulsive loads to be powered without compromising its aerodynamics.
