UNMANNED HIGH-SPEED HELICOPTER-AIRPLANE Russian patent published in 2018 - IPC B64C27/24 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation technology and can be used in the design of unmanned and deck high-speed helicopter-planes. Unmanned high-speed helicopter-airplane (UHSHA) is equipped with two systems with various screws in propulsion (PS) and two-screw coaxial bearing systems (TCBS). TCBS includes under the wings of a closed structure (CSW) a pair with the opposite rotation of single-blade large screws with profiled back-tapered counterbalances, which ensure the creation of vertical thrust only with VTOL and STOL operations. DRS-X1 includes a smaller screw mounted in the rear annular channel (RAC) to create control moments in the performance of VTOL operations and hovering, and a flywheel in a high-speed horizontal flight with two fixed wing blades of the upper and lower coaxial screws located above the fuselage and under the fairing of the first arrow wing (FAW), respectively. FAW has an inverse narrowing of the inner sections. In the middle of the span of each half-wing on the underwing gondolas, nodes of deflection upward in the parking configuration of the trapezoidal end parts with FAW external drooped ailerons of the CSW system are installed.

EFFECT: simplification of longitudinal-lateral balancing with hovering, high-speed horizontal flight and in transient modes is provided.
