Patents by Inventor Johannes Stuhlberger

Johannes Stuhlberger 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).

  • High frequency-stabilized combustion in aircraft gas turbines
    Patent number: 9625145
    Abstract: A gas turbine includes a combustion chamber and a microwave source to produce microwave radiation. The gas turbine is arranged to guide the microwave radiation into a cavity of the combustion chamber. Due to the microwave radiation, in the cavity of the combustion chamber, combustion in the cavity may be supported and thus lean operation of the gas turbine is made possible.
    Type: Grant

    Date of Patent: April 18, 2017
    Assignee: Airbus Defence and Space GmbH
    Inventors: Juergen Steinwandel, Johannes Stuhlberger
  • Hybrid drive and energy system for aircraft
    Patent number: 9194285
    Abstract: A hybrid drive system for aircraft, in particular helicopters, with at least one energy generating module having an internal combustion engine and a generator that can be powered by the latter to generate electrical energy, and at least one electric motor for powering a drive means of the aircraft.

  • Drive system for helicopters
    Patent number: 9004395
    Abstract: The rotors of a helicopter are directly connected with electric high-torque motors, and are powered by the latter. Energy generation and rotor drive are separate from each other. The high-torque motor of the main rotor is pivoted to the cabin canopy, so that it can be tilted together with the main rotor.

  • Hybrid drive for helicopters
    Patent number: 8870114
    Abstract: The rotors of a helicopter are powered by electric motors. The electrical energy required for this purpose is produced by a motor-generator unit, which comprises one or more internal combustion engines. The motor-generator unit can be secured under the cabin floor. This yields a hybrid helicopter that can set the rotational frequency of the rotors within a large interval.
