HIGH-SPEED AMPHIBIA SYNCHROCOPTER Russian patent published in 2018 - IPC B64C35/00 B64C27/08 

FIELD: aviation.

SUBSTANCE: high-speed amphibia synchrocopter (HSASC) has a two-prop scheme with closely spaced crossing props and a power unit with an engine, transferring torque via the main gearbox and shaft to the bearing props mounted on fuselage pylons, a vertical tail unit with a stabiliser and a non-retractable wheeled chassis. HSASC is executed with the propulsion-steering system in the longitudinal scheme with the criss-cross bowl-shaped props. Two-blade props are mounted on the output shafts of the main reduction gear in profiled fairings. The front rotor is tilted at an angle of α_P=5° forward on the flight. Two traction props in the cantilevered annular channels (CAC), located on the internal sections of the high wing, create control moments and cruise thrust. The high wing met with a negative angle of transverse V, implemented by outside tilted down sealed partitions, mounted on the outer sides of the CAC and equipped with flaperons and floats throughout their extent.

EFFECT: required power to control the roll and course when hovering is reduced, excluding the inclination of the props blades and their ends.
