The invention discloses a wing rudder angle transformation structure for an underwater glider towing test, and belongs to the field of hydrodynamic experiments. Comprising a rudder plate, a left angle piece and a right angle piece, and the two sides of the rudder plate are fixed to the middle section of the rear edge of a wing through the left angle piece and the right angle piece respectively; the left angle piece is a strip-shaped plate with an included angle, the front half section of the left angle piece is fixedly mounted in a mounting groove in the surface of the wing, the upper surface is flush with the surface of the wing, and the rear half section is fixed to the left side of the rudder plate; an acute included angle between the front half section and the rear half section of the left angle sheet is a rudder angle; the right angle piece and the left angle piece are of a symmetrical structure. According to the invention, through the ingenious adaptive design of the angle sheet, the connection surfaces of the angle sheet and the wing and the rudder plate are conformal, the original hydrodynamic characteristics of the angle sheet can be maintained during an experiment, and the measured data are more accurate and real. By adopting the thought of replacing the angle piece, a steering engine with a complex structure is prevented from being used.
本发明一种水下滑翔机拖曳试验机翼舵角变换结构,属于水动力学实验领域;包括舵板、左角度片和右角度片,所述舵板的两侧分别通过左角度片和右角度片固定于机翼后缘中段;所述左角度片为带有夹角的条形板,其前半段固定安装于机翼表面的安装槽内,且上表面与机翼表面平齐,后半段固定于舵板左侧边;左角度片的前半段和后半段之间的锐角夹角为舵角;右角度片与左角度片呈对称结构。本发明通过巧妙的角度片适应性设计,使得角度片与机翼和舵板的连接面都得以保形,能够在实验时保持其原本的流体动力特性,使得测出的数据更为准确且真实。通过采用可替换角度片的思路,从而避免了使用结构复杂的舵机。
