ABSTRAKT

Investigated numerically are the flow pattern and the aerodynamic characteristics of a new generation of winged re-entry space vehicles (RSVs) of comparably small size. Examined is the RSV — TsAGI [1, 2] layout, which has a complicated configuration: strongly blunt fuselage, wing with variable-swept leading edge and with two tips, elevons, fuselage trim panel, and a vertical fin with a rudder and air brake installed on it. Calculations were performed for inviscid and thermally nonconductive gas within the range of Mach numbers M = 1.1−16.5 and within the range of angle of attack α = 0−45°. The main aerodynamic characteristics of RSVs, i.e., their flow field topology features, are defined by means of numerical simulation, and the influence of real air thermophysical properties at hypersonic velocities was investigated by means of numerical simulation.
