Komarov B. Adaptive wing with cross-flow fan

The dissertation is dedicated to the research and development of propulsive power plants, specifically the design of the wing and fuselage using a cross-flow fan propulsion system. The paper explores the history of implementing tangential fans in aviation as rotor propulsion systems. A new mathematical model has been created for rapid calculation of propulsion systems based on the "Propulsion-Wing" and "Fan-Wing" structural schemes. This model has been validated through practical experiments. Additionally, simulations of the aerodynamic characteristics of models under various flight conditions were conducted to confirm the computational results. New experimental wing profiles have been developed. A novel type of rotor propulsion system without partitions between sections and without a shaft inside, obstructing the airflow, has been proposed. These modifications reduce air resistance, promote free air circulation, and prevent the obstruction of airflow passing through it. The impact of the shape and angle of blade installation for optimal air capture and discharge from the propulsive system has been investigated. The rotor blades were experimentally tested for strength, and the structure was reinforced with blade connection elements to prevent the destructive effect of centrifugal force at high rotation speeds. These modifications almost do not impede airflow and allow for a reduction in the overall structure's mass through the use of highly elongated blades. The dissertation discusses new and prospective layout schemes of aircraft incorporating propulsive systems in their design and evaluates their rationality.
