摘　　要：将自主可控的合成双射流激励器集成于常规布局飞行器中,进行了三轴无舵面控制飞行试验,验证了分布式合成双射流对飞行器巡航时的无舵面姿态调控能力.对合成双射流激励器进行改进,设计了分布式三轴姿态控制合成双射流激励器,滚转环量控制激励器分别安装于两侧机翼翼尖处后缘,射流出口靠近压力面;偏航反向合成双射流控制激励器分别安装于靠近两侧机翼翼尖20%弦长处,上、下沿展向均匀布置;俯仰环量控制激励器安装于V尾下的平尾后缘,射流出口靠近压力面.针对巡航速度为30 m/s的飞行器,进行了三轴姿态控制飞行试验,结果表明:分布式合成双射流实现了飞行器巡航时的三轴无舵面姿态操控;横航向控制存在耦合,滚转环量控制激励器实现了飞行器的双向滚转操控,能产生的最大滚转角速度达16.87°/s,偏航反向合成双射流控制激励器实现了飞行器的双向偏航操控,能产生的最大偏航角速度达9.09°/s;俯仰环量控制激励器实现了飞行器的纵向控制,能产生的最大俯仰角速度达7.68°/s.The autonomous and controllable dual synthetic jet actuators were integrated into an aircraft with a conventional layout and then,the three-axis flight tests without rudders were carried out to verify the ability of distributed three-axis dual synthetic jet actuators to control the attitudes of the aircraft during the cruising.First of all,the dual synthetic jet actuators were improved,and the distributed three-axis attitude control dual synthetic jet actuators were created.Moreover,roll circulation control actuators were installed on the trailing edge of both-side wings close to the wingtips,where their jet outlets were close to the pressure surface.Yaw reverse dual synthetic jet actuators,evenly arranged on the upper and lower surfaces along the span direction,were respectively installed at the 20%chord of the wing close to the wingtips on both sides.Pitch circulation control actuators,whose outlets were also close to the pressure surface,were installed on the trailing edge of the in-house flat tail under the V tail.Then,for an aircraft with a cruising speed of 30 m/s,the three-axis attitude control flight tests without rudders have been carried out during the cruising.Relevant flight attitude information shows that distributed dual synthetic jets could realize the three-axis attitude control of the aircraft without rudders during the cruising.What’s more,the coupling has been shown between the lateral and heading control.The two-way roll control of the aircraft could be realized by the roll circulation control actuators,and the maximum roll angular velocity that can be generated is 16.87°/s.In addition,yaw reverse dual synthetic jet actuators could achieve the two-way yaw control,and the maximum yaw angular velocity that can be generated is 9.09°/s.Pitch circulation control actuators could realize the longitudinal control of the aircraft,and the maximum pitch angular velocity that can be generated is 7.68°/s.
