  • Electrical current converter/rectifier with integrated features
    Patent number: 11834987
    Abstract: A propulsion system for use with an aircraft includes a gas turbine engine, an electric power system, and at least one propulsor. The gas turbine engine includes a compressor, a combustor, and a turbine. The electric power system includes a generator coupled to the gas turbine engine to generate electrical energy, power electronics connected to the generator to receive the electrical energy from the generator, and a motor configured to produce rotational energy in response to receiving electric energy from the power electronics. The propulsor is configured to use rotational energy received from the motor of the electric power system to generate thrust for propelling the aircraft.
    Type: Grant
    Filed: March 16, 2021
    Date of Patent: December 5, 2023
    Assignee: Rolls-Royce Corporation
    Inventors: John P. E. Forsdike, Krishnamoorthi Sivalingam, Palanisamy Mohan Kumar, Rakesh Murali
  • Aircraft hybrid propulsion system including cold plate for a high density power converter
    Patent number: 11807381
    Abstract: A hybrid propulsion system for use with an aircraft includes a gas turbine engine, at least one propulsor, and an electric power system. The electric power system is coupled to the gas turbine engine to generate electrical energy and the propulsor to provide electrical energy to drive the propulsor. The electric power system includes a thermal management system configured to cool a heat load generated by the electric power system.
