Experimental Studies of X-47B-type Unmanned Aerial Vehicle in TsAGI T-102 Wind Tunnel to Assess Effectiveness of Aerodynamic Controls in Longitudinal Channel

摘要

The results are given on the experimental studies of integral aerodynamic characteristics of X-47B-type “flying wing” unmanned aerial vehicle model. The dependence of the lift coefficient on the angle of attack for different trimmings and static margin is evaluated. It is shown that rational combination of aerodynamic surface deflections allows increasing sufficiently the trimmed lift coefficient values for take-off and landing flight regimes.
