Problems solved by technology

Or install a control ring and a stop ring at the tail, but it will generate a large flow resistance. Although it is suitable for the maneuvering navigation of the vehicle body, it is difficult to achieve the supercavitation drag reduction capability required for supercavitation high-speed long-distance navigation.

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] A control device applied to autonomous and stable navigation of a vehicle, such as figure 1 As shown, it includes a cavitator 2, an exhaust port 8, a vent valve 7, a vehicle body 6, a tail bubble sensor 5 and a tail axial nozzle 9,

[0026] The head of the vehicle 6 is provided with a cavitator 2, and an exhaust port 8 is provided at the tail of the cavitator 2, and the gas discharged through the exhaust port 8 forms a supercavitation 3 on the outer surface of the vehicle 6, and the cavitator 2 The position of the starting point of the supercavitation 3 can be controlled, and the ventilation valve 7 connected with the exhaust port 8 is arranged inside the vehicle body 6. The throat area of ​​the exhaust port 8 is the flow area required by the limit flow of the supercavitation 3, which is used here The jet port design with maximum flow limitation can p...

Abstract

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 resistance is avoided, and high-speed navigation achieving supercavity drag reduction is facilitated.

Description

technical field [0001] The invention relates to a control device and method applied to autonomous and stable navigation of a navigation body, belonging to the control field of autonomous and stable navigation of a navigation body. Background technique [0002] The traditional underwater speed is only 30-70 knots. Faced with the continuous innovation of underwater vehicles and the continuous improvement of navigation performance, the underwater future will develop towards high speed, large depth and long range. For example, the speed of supercavitation vehicle can reach 200 knots, and the combination of supercavitation vehicle and underwater vehicle technology forms an underwater long-distance high-speed vehicle. Russia represents the highest level in the field of supercavitation. The advent of "Blizzard" represents a revolutionary leap in underwater weapons. The powerful deterrent effect brought by its underwater high-speed strike has set off a research boom in supercavitat...
