The paper considers a complex criterion for assessing the characteristics of the radio-transparent fairing of the supersonic aircraft onboard radar. The algorithm for research performing which will allow to establish interrelation between radio, aerodynamic and the main geometrical characteristics of radio-transparent nose fairings, such as lengthening of the forward part of a fuselage, an angle of inclination of a tangent to a curve forming a body of rotation and a discriminant of a curve generator is developed. The process of forming the geometric shape of the onboard radar radio-transparent fairing of a supersonic aircraft is based on two interrelated processes: providing the appropriate radio technical characteristics of the fairing to meet the requirements for the range of the aircraft radar detection and minimizing the drag of the nose of the fuselage. Research following the proposed algorithm allows forming technical recommendations for the selecting rational geometric parameters of onboard radar radio-transparent fairing of a supersonic aircraft at the early stages of aircraft design.
