Hybrid turbomachine comprising an electric generator, a gas generator-equipped with an air inlet and with an exhaust and an acoustic monitoring system comprising a control unit and a plurality of loudspeakers. At least a first loudspeaker is disposed on the electric generator, and/or at least a second loudspeaker is disposed on the air inlet of the gas generator, and/or at least a third loudspeaker is disposed on the exhaust of the gas generator. The control unit of the acoustic monitoring system is mounted on the electric generator and is configured to make an AC-DC electrical conversion of the electromotive force of the electric generator into an adjustable DC voltage intended to be distributed to loads or to energy storage means.

Hybrid turbomachine for aircraft with an active acoustic control system

A propulsion assembly for aircraft includes a single-shaft engine turbomachine including a combustion chamber and a rotatably mounted shaft that turns at a turbomachine rating; an electrical generator coupled to the shaft; and a control system. The control system includes a fuel pump that brings fuel into the combustion chamber at a fuel flow rate which is a direct function of an ambient pressure and of the turbomachine rating, and power electronics that are coupled to the electrical generator and that control an electrical power drawn off the electrical generator so as to attain a target turbomachine rating.

Turbogenerator with simplified control system for aircraft

A turbogenerator () for an aircraft () comprising: a turboshaft engine (); an electric generator () comprising a rotor () driven mechanically by the turboshaft engine () and a stator () supported by a housing () of the electric generator (); characterized in that the turbogenerator () comprises a static separator () for separating an air/oil mixture coming from the turboshaft engine (), the static separator () being positioned around the housing () of the electric generator ().
