Ivan Khamin, an engineer from Khakassia, has developed a concept for a vertical take-off and landing aircraft with rotors placed inside the fuselage. The aircraft features a cabin and two bearing arms – one at the front and one at the rear.
Inside them are rotors in diffusers. This design allows for thrust control without a classic swashplate, by changing the position of the rotors within the channels.
The key feature is the blade design. Each rotor consists of two elements forming a hemisphere. During rotation, their position automatically changes due to centrifugal forces, allowing thrust to be adapted to the flight mode.
Khamin implemented the drive through a system of shafts and gearboxes, and the tilt control of the rotors using hydraulics. A gas turbine engine in combination with an electric machine, operating as both a motor and a generator, is proposed as the power plant.
According to the author's idea, such a scheme can reduce the dimensions of the aircraft, improve balancing, and expand its application possibilities. In particular, the aircraft is potentially capable of hovering, landing on confined areas, and operating near surfaces.
