Ukrayinets' Y. The aerodynamic characteristics of coaxial rotor flying vehicles carrying system.

The dissertation is devoted to development of calculation technique of the aerodynamic characteristics of coaxial screw flying vehicles. The discrete vortex method with the closed vertical frame as a discrete feature is developed at this work. The velocity fields induced of screw currents, induced by screw on aerodynamic characteristics of wing, engine nacelles, empennage are investigated. The influences of engine operational mode changes, deviation of wing mechanization, approach to separation surfaces, presence of sliding on aircraft momentum characteristics are investigated. The main results of investigation are introduced in industry and in the educational process.
