Engineering approach to determination of parameters in high-speed aircraft designing

The concept of “separation” of the designed geometry was proposed as a way to speed up calculations in high-speed aircraft (HSA) designing and increase the accuracy of determining designing parameters. Methods for simplifying the HSA geometry using simple geometries and their compositions are determined. A method for determining external and internal parameters using correlation relations and exact methods is proposed. Modules for calculating the heat flux and friction stresses on the surfaces of a sharp plate and a sharp cone, based on the criterial relations of the boundary layer theory, are implemented. Modules were verified and validated.

Инженерный подход к определению параметров при проектировании высокоскоростных летательных аппаратов

Предложена концепция «дискретизации» проектируемой геометрии как способ ускорения расчетов при проектировании высокоскоростных летательных аппаратов (ВЛА) и увеличения точности определения проектных параметров. Определены способы упрощения геометрии ВЛА с использованием простых геометрий и их композиций. Предложен способ определения внешних и внутренних параметров с использованием корреляционных соотношений и точных методов. Реализованы модули расчета теплового потока и напряжений трения на поверхностях острой пластины и острого конуса, основанные на критериальных соотношениях теории пограничного слоя. Проведены верификация и валидация модулей.
