Dinamika presents VTOL UAS prototype

CSTS Dinamika has completed an R&D project for conceptual design of a new multipurpose vertical takeoff and landing (VTOL) unmanned aerial system (UAS).

A collaborative effort with industry partners, this project was realized in line with the best traditions of the Russian aviation engineering school. From the very beginning the project was characterized by meticulous R&D work at each stage of the conceptual design process. The project’s early stages involved study and consideration of similar systems and prototypes currently existing in the world, patent research and definition of the system’s operational concept. We analyzed key technologies for the project, defined conceptual design of the entire system and drone demonstrator models (aerodynamic configuration, power plant, payload, etc.) and developed guidelines for ground and flight testing. The project also involved research and experimental testing of various VTOL drone configurations (fixed-wing, rotary-wing and tiltrotor variants). We built a series of prototype VTOL drones based on various aerodynamic configurations to analyze their suitability for a range of civil and military tasks.

Our further efforts included analysis of strength characteristics for composite materials used in the drone prototypes. We built wind tunnel test models for the principal tiltrotor concept including an operative power plant model. Those underwent testing in TsAGI’s wind tunnels, which proved the selected tiltrotor configuration highly effective for this type of aerial vehicles due to the comprehensive approach employed in the development of the drone’s wing structure and general configuration. Our engineers designed and built test benches for the vehicle’s power plant, steering mechanisms and servo unit. Test benches were also used to determine airframe deformation, vibration and control characteristics for all the power plant operation modes.

Next stage of the project featured development of a series of alternative VTOL drone prototypes based on various aerodynamic configurations, ground control station, radio control and data exchange interface, satellite navigation and landing system, payload mockup model and ground UAS operator station mockup. The alternative drone configurations were put to thorough bench, ground and flight testing in order to verify the vehicle’s conceptual design and system requirements. Finally, we successfully completed flight testing of all the UAS prototypes with each drone configuration developed in the course of the project.

As a result of this research and testing effort, we were able to finalize design, structure and components of the new VTOL UAS, evaluate its technical, engineering and technological feasibility and also come up with proposals for the implementation of alternative unmanned aerial systems based on different aerodynamic configurations and suitable for a variety of applications.

Ultimately, the project has yielded a considerable technology advance to the development of new VTOL unmanned aerial systems that can be used for a wide range of civil and military applications.
