MODELING OF THE FLOW AROUND AN AIRCRAFT EQUIPPED WITH BRIX-KORT NOZZLE SYSTEM

VTOL aircraft are of growing interest due to their versatility and ability to operate in confined spaces. A promising development of this direction is theapplication of a set of technical solutions for aerodynamic layouts to ensure the necessary aerodynamic quality of the aircraft in all flight modes simultaneously, namely, equipping the flying platform with a system of Brix-Court nozzles, which are capable of increasing the aerodynamic efficiency ofthe aircraft engines in both vertical and horizontal flight modes. A comprehensive study of this concept is a necessary step towards the creation of conceptually new flying aircraft - systems of ultra-small mobile flying platforms, the flight pattern of which depends on the orientation of the aircraft inspace. The object of research: models of aircraft with Brix-Court nozzles, for vertical take-off and landing and horizontal flight. The aim of the work isto develop a theoretically substantiated concept of a vertical take-off and horizontal flight (VTOL type) aircraft with a payload of up to 200 kg, capableof providing horizontal flight for 10 – 30 minutes at speeds up to 100 km/h. The main attention is paid to the creation of an effective aerodynamic layout,analysis of traction characteristics and research into the possibilities of using specialized aerodynamic elements (in particular, Brix-Court typenozzles) to increase the efficiency of engines in vertical and horizontal flight modes.
