Specialists of the N.E. Bauman MSTU have developed an unmanned aerial vehicle with two rotary engines according to the tilt-rotor scheme. The novelty combines the properties of an airplane and a helicopter and is designed to take off even from unprepared sites.
It was proposed to perform the convertiplane according to the aerodynamic scheme and equip it with two engine nacelles at the ends of the wing. Each nacelle contains a power frame, an engine rotation mechanism with a servo drive, a rocker and a rod, as well as a two-section skin with a cutout for the engine stroke.
The rotation is carried out up to 95°, which ensures the transition from vertical mode to horizontal flight.
Instead of a wheeled chassis, skids made of plastic materials are used. This reduces weight and resistance, increasing range and speed. Control in vertical mode is achieved by tilting the propellers and differentiating thrust.
According to the developers, the new scheme simplifies platform scaling and increases the resource of components compared to three-engine solutions.
