The invention discloses an aircraft control surface jet flow exciter, and relates to the technical field of jet flow exciters, the aircraft control surface jet flow exciter comprises a medium inlet, a jet flow cavity, a jet flow seam and a transition flow channel, the jet flow cavity is arranged in a control surface along the length direction of the control surface, the jet flow seam is arranged on the upper surface of the control surface along the length direction of the control surface, and the transition flow channel is located in the control surface. One end of the transition flow channel communicates with the jet flow cavity, and the other end of the transition flow channel communicates with the jet flow seam. The jet flow cavity adopts single-end air supply and can be used for a control surface with a small internal space, the jet flow seam (slit) is adopted for air blowing, the uniformity of the jet flow speed in the length direction can be guaranteed on the premise of single-end air supply, and the transition flow channel is used for connecting the jet flow cavity and the jet flow seam so as to reduce the energy loss of a medium; the jet flow cavity is a device used for connecting the medium inlet and the jet flow seam and provides a stable and uniform air source for the jet flow seam.

    本发明公开了一种飞机舵面射流激励器,涉及射流激励器技术领域,包括介质入口、射流腔、射流缝以及过渡流道,射流腔沿舵面长度方向布置在舵面内部,射流缝沿舵面长度方向布置在舵面的上表面,过渡流道位于舵面内部,过渡流道一端与射流腔连通,另一端与射流缝连通,介质入口与射流腔的一端连通。本发设计的射流腔采用单端供气,可用于内部空间较小的舵面,采用射流缝(狭缝)吹气,在单端供气的前提下能够保证长度方向射流速度的均匀性,过渡流道用于连接射流腔和射流缝,目的是减小介质的能量损失;射流腔为用于连接介质入口和射流缝的装置,为射流缝提供稳定均匀的气源。
