The United Aircraft Corporation (OAK) has found a solution to the problem of vertical take-off and landing (VTOL) aircraft design, which involves losing part of the lift during maneuvering. The scheme was officially published in the Rospatent database.
OAK designers proposed shifting course control from the main lifting rotors to a separate power plant with two impellers built directly into the longitudinal wing spars.
These impellers will create multidirectional thrust and turn the aircraft without changing the operating mode of the main engines.
The impellers inside the spars also do not create additional aerodynamic drag in horizontal flight and are better protected from icing, which eliminates the need for a separate anti-icing system in the design.
Previously, Russia also developed a kit for converting a light production aircraft into a hybrid VTOL. The unexpected solution is designed for aircraft with a high wing, struts, and a nose landing gear.
