Designing a Basic Model of an Unmanned Aerial Vehicle for the Subsequent Development of a Family of Samples with Different Purposes

The general initial positions making basis of technical intention of the maneuverable multimode unmanned aerial vehicle, that determined forming the general configuration and the choice of key parameters are briefly outlined. The overview and reasoning of accepted design and technical decisions are carried out; the principles of their functioning are stated. Methodical features of aerodynamic designing in relation to complexification of the unmanned aerial vehicle of integrated configuration are revealed. Results of verification of design models by results of wind tunnel tests of scale model of analog of aerodynamic configuration are presented. The parametrical geometrical model of the airframe is created, and results of computational researches of alternative designing in selection process of key parameters of lifting system are given. The parametrical geometrical model of air-gas paths is created; the results of iteration cycle of profiling of submerged inlet device and ejector nozzle of step type are presented; the capability of functioning of system of the airframe with integrated power plant is shown.
