本发明公开了种应用于航行体自主稳定航行的控制装置及方法，将呈环状的尾部轴向喷口设置在航行体尾部底端的外沿上，通过喷流形成较小流量周向封闭的轴向喷流，形成的轴向喷流的引射作用可以对超空泡尾部收缩产生的周期性脱落和断裂，起到稳定作用，防止超空泡尾部的振荡、减少超空泡尾部气体泄露，有利于减少航行器高速航行时的气体消耗。此外，使用尾部轴向喷流而不是硬的凸起来稳定超空泡，不会产生额外的阻力，有利于实现超空泡减阻的高速航行。 The invention discloses a control device and method applied to autonomous and stable navigation of a navigation body. A ring-shaped tail axial nozzle is arranged on the outer edge of the bottom end of the tail of the navigation body. A small-flow-quantity circumferentially-closed axial jet stream is formed through jetting, the ejecting effect of the formed axial jet stream can play a role in stabilizing periodic falling and breaking generated due to shrinkage of the tail of a supercavity, oscillation of the tail of the supercavity is prevented, gas leakage of the tail of the supercavity is reduced, and reduction of gas consumption during high-speed navigation of an aircraft is facilitated. In addition, the tail axial jet stream rather than a hard protrusion is used for stabilizing the supercavity, extra
