The Riga Technical University (RTU) is developing a system for launching pico- and nanosatellites into low Earth orbits (LEO). The system as a platform includes the transport aircraft A319 and a three-stage launching system with the code name LatLaunch. One of the supersonic fighters was selected as the LatLaunch aerodynamic prototype based on its technical characteristics (flight altitude record, flight speed record, and information availability on some aircraft aerodynamic characteristics). The article presents the results of modeling the aerodynamic characteristics of the first and the second stages of the LatLaunch system, represented by modeling using 3D modeling of SolidWorks software and Scilab at subsonic, transonic, supersonic, and low hypersonic flight speed modes of LatLaunch flight.
