Returned Aircraft Aerodynamic Characteristics Definition Based on its Models’ Analysis Results During a Free Flight in a Wind Tunnel
Models tests methodology during a free flight in a wind tunnel stream and aerodynamic characteristics analysis results of a segment-conical returned aircraft, having a length to diameter ratio λ = L/D = 0,884 and a reverse cone angle Θs = – 20° are presented. Analysis tests results with assessment of the impact on the value of the damping coefficient in the range of Mach numbers equal 0,6 – 1,73 and in the range of Reynolds numbers equal 10 <sup>6 </sup>– 1,34 10 <sup>6</sup>.
