Benoit Meys has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10161267
    Abstract: A test bench for turbomachine comprising: an installation zone for turbomachine; an active system for attenuating the noise emissions produced by the turbomachine. The active system includes an attenuation zone with emitters such as loudspeakers; a first microphone placed downstream of the turbomachine; and a second microphone placed downstream of the attenuation zone. The system reduces the turbomachine waves on the basis of the measurements from the first microphone and from the second microphone. The invention also proposes a method for attenuating the noise emissions from the turbomachine tested in the test bench.

  • Patent number: 10107717
    Abstract: The invention relates to a test bench for an axial turbine engine, especially for a turbojet, including: a chamber intended to accommodate the turbine engine; a vertical inlet channel connected to the chamber upstream of the turbine engine; and a vertical outlet channel connected to the chamber downstream of the turbine engine; at least one wind power engine capable of converting the kinetic energy of a portion of the gas stream generated by the turbine engine into mechanical energy; the wind power engine or at least one of the wind power engines is situated in the vertical inlet channel and/or the vertical outlet channel. The invention also relates to a process for recovering energy of such a test bench.

  • Patent number: 9973047
    Abstract: The invention relates to a rotating electric machine, such as a dynamometer. The rotor of the machine comprises a circular row of resultant magnetic poles of which the polarity forms an alternation of opposed poles. The resultant poles each include a pair of permanent magnets in a “V”, each equipped with a north pole N, a south pole S, and opposed faces, where the magnet poles are located. In each resultant pole the magnets are disposed so as to have faces having identical polarities, which faces are oriented radially outwardly, facing towards one another, thus forming therebetween an angle ? between 90° and 110°, which makes it possible to increase the efficiency. The invention also relates to a turbomachine test stand equipped with a dynamometer enabling a recovery of electrical energy. The invention also relates to a hybrid motor vehicle propelled by the rotating electric machine.
