Helicopter design with one big supporting propeller, and others around the edge of the craft for control and balance. The firm that "communicated" the patent doesn't seem to be an applicant exactly according to the document itself, and it was presumably the assignee but that is not explicit either

  • Applicant firm location: 6, Boulevard du Point du Jour, Issy les Moulineaux, France
