The Siberian Aeronautical Research Institute named after S.A. Chaplygin (SibNIA) has completed a comprehensive test program for an electric/hybrid-powered rotorcraft demonstrator. Testing included both ground and flight phases. Engineers evaluated propulsion system performance, rotor dynamics, and avionics integration. The team also validated the ground control station (GCS), which provides flight monitoring and remote piloting capabilities, according to a SibNIA press release.
The demonstrator uses coaxial rotors powered by electric motors. This design delivers enhanced stability and control during vertical takeoff and landing (VTOL) operations. The aircraft employs a reaction control system that uses directed air jets through dedicated nozzles to manage yaw, roll, and pitch. This approach maintains control authority in hover and at low speeds, where conventional aerodynamic control surfaces lose effectiveness. The absence of moving control surfaces improves structural reliability and reduces the acoustic footprint.
The project targets urban and regional air mobility (UAM/RAM) platforms, including unmanned cargo operations. The test results will serve as a foundation for developing light aircraft capable of transportation missions within metropolitan areas and remote locations. Engineers will use the collected data to refine the aerodynamic design and optimize energy performance of future prototypes.
Electric and hybrid-electric propulsion systems can significantly reduce operating costs and noise levels. According to SibNIA, electric propulsion eliminates emissions entirely, while advanced flight control systems enhance operational reliability. This aligns with the broader industry trend toward sustainable and energy-efficient aviation solutions.
The demonstrator development is part of a government-funded program advancing electric aviation technologies in Russia. Test results lay the groundwork for subsequent development phases, including pre-production aircraft and certification testing preparation.
