  • Efficient low-noise aircraft propulsion system
    Patent number: 11878805
    Abstract: An aircraft propulsion system comprising a reciprocating liquid cooled engine housed within the fuselage driving twin fuselage mounted ducted-fans is disclosed. The propulsion system may be liquid cooled with a liquid cooled exhaust and at least one turbocharger. The ducted-fans may run fan blade tip speeds of up to 97% Mach driven by a near constant RPM engine through a continuously variable transmission. The propulsion system may be low noise and may meet environmental standards typical in the automotive industry.
    Type: Grant
    Filed: February 14, 2022
    Date of Patent: January 23, 2024
