As shown in fig. 1, the active flow control method applicable to the underwater vehicle with the X-shaped control surface of the embodiment comprises a vehicle body 1, four groups of rudders 4 are installed at the end part of the vehicle body 1 along the circumferential direction at intervals to form the X-shaped control surface, water inlet and outlet ports 3 are formed in the side surfaces of two sides of a single rudder 4, and water inlet or outlet actions of the water inlet and outlet ports 3 are actively controlled by a power pump 8; as shown in fig. 2, the device further comprises a sensor group 5 arranged on the surface of the rudder 4 outside the circumference of the water inlet and outlet 3, wherein the sensor group 5 monitors the fluid pressure born by the surface of the rudder 4;
when the sensor group 5 detects that the pressure on the side surface of the rudder 4 is instantaneously and greatly increased, judging accumulated fluid, and controlling the water inlet and outlet ports 3 on the side surface of the corresponding rudder 4 to perform water outlet action through the power pump 8 to blow off the fluid accumulated on the surface of the rudder 4; on the contrary, when the sensor group 5 detects that the pressure on the side surface of the rudder 4 is reduced even zero and is in a vacuum state, the sensor group judges that the fluid is less or even no, and the power pump 8 controls the corresponding water inlet and outlet port 3 to perform water inlet action so as to suck the remote fluid to the surface of the rudder 4.
The water inlet and outlet ports 3 are respectively arranged on the side surfaces of each rudder 4 of the X-shaped control surface to form a blowing and sucking device, so that the purpose of improving and optimizing the flow field around the control surface is achieved, and the fluid around the control surface is always in a relatively uniform distribution state; the uniform distribution of the flow can lead the internal separation of the fluid to be less, the crushing of the vortex structure can be greatly reduced, so that less energy is dissipated, the corresponding pulsation pressure and resistance are reduced, the rudder efficiency is greatly improved, and the flow-induced noise is greatly reduced.
In actual use, the sensor group 5 monitors and feeds back the absolute value of the pressure, and the pressure is determined by increasing or decreasing the pressure.
The blowing and sucking direction of the water inlet and outlet 3 during water outlet or water inlet is vertical to the surface of the rudder 4, so that the effect of blowing and sucking fluid is effectively ensured.
The water inlet and outlet of the water inlet and outlet 3 on the side surfaces of the two sides of the single rudder 4 are opposite in action.
As shown in fig. 3, the power pump 8 is arranged inside the vehicle body 1, and the power pump 8 is communicated to the corresponding water inlet and outlet 3 through the pipeline 7, so that the reliable operation of blowing and sucking is realized, the reasonable layout is performed, and the overall streamline shape of the underwater vehicle is not influenced.
The power pump 8 is a bidirectional water pump and has a bidirectional water inlet and outlet function; the bidirectional water pump switches water inlet or outlet states of the water inlet and outlet 3 through switching forward work and reverse work; for example, when the power pump 8 rotates in the forward direction, water flow is sucked into the power pump 8 and matched with 'sucking' operation; when the power pump 8 rotates reversely, water flows out of the power pump 8 to cooperate with the blowing operation.
The power pump 8 is a double-port bidirectional water pump, and water inlet and outlet ports 3 on two side surfaces of the single rudder 4 are correspondingly communicated to double ports of the double-port bidirectional water pump respectively through pipelines 7; under the action of the power pump 8, the water inlet and outlet 3 on one side of the rudder 4 is in a blowing-off operation state, and the water inlet and outlet on the other side of the rudder 4 is in a sucking operation state.
In the embodiment, the use of the double-port bidirectional water pump enables the whole structure to be compact, and the maximum function can be exerted in an effective layout space.
The four rudders 4 are uniformly distributed along the circumferential direction of the aircraft body 1 at intervals, and the axial angle spacing between the adjacent rudders 4 is 90 degrees; the individual rudders 4 are connected to the aircraft body 1 via rudder bars 6, and the lines 7 are provided from the rudders 4 through the inside of the rudder bars 6 to power pumps 8 in the aircraft body 1.

In the embodiment, the rudder stock 6 is hollow, so that the structural weight can be reduced to the greatest extent while the structural strength is met, and the rudder efficiency is improved; on the other hand, the hollow structure is designed to facilitate the arrangement of the pipeline 7 on the rudder 4.

In the embodiment, the double-port bidirectional water pump can be a Tech SNBY516 type product, is provided with two ports, and is respectively communicated with the water inlet and outlet 3 on the two sides of the same rudder 4 through two water pipes to realize water absorption or drainage; the water absorption or drainage is finally communicated and stored in the water bin 9.
The sensor group 5 includes a plurality of pressure sensors arranged circumferentially with the water inlet 3 as a center.
In one of the cases of the arrangement of the sensor groups 5 in fig. 2, eight independent sensors are arranged with the water inlet and outlet 3 as the center, and the sensor groups 5 with the same arrangement mode are arranged on both sides of the rudder 4.
By means of the pressure sensor array arranged on the rudder 4 surface, the fluid condition of the rudder 4 surface is judged by reading in the pressure signal to make an active control decision, and corresponding operation is performed according to the fluid condition.
The outer wall surface of the middle part of the other end of the aircraft body 1 opposite to the rudder 4 is provided with a command room enclosure 2 for timely and effectively controlling the navigation of the underwater aircraft, including the work of a blowing and sucking device.
The basic principle of the invention is that an active control method of intervention is adopted, which is embodied as the blowing-off and sucking actions of a blowing-sucking device. When a large amount of fluid is accumulated in front of the X-shaped control surfaces (particularly four control surfaces), the pressure of the control surfaces is increased greatly instantaneously, a blowing-sucking device of the control surfaces is immediately started through a judging program, and an operation command is blowing off to actively blow off the fluid accumulated on the control surfaces, so that the pressure of the control surfaces is relieved; conversely, when the fluid behind the X-shaped control surface (particularly the control surface of four rudders) is less (the extreme case is in a vacuum state, and the back of the control surface is almost free of any fluid at the moment), the blowing and sucking device of the control surface is immediately started through a judging program, the operation command is 'sucking', the fluid at the far distance from the control surface is actively sucked to the control surface, the local pressure is negative after the blowing and sucking device of the control surface is developed, and the surrounding fluid is rapidly gathered to the control surface under the driving of the pressure difference; in so doing, the fluid surrounding the X-shaped control surface is always in a relatively uniform distribution.
By arranging the blowing and sucking device on the control surface of the underwater vehicle, different blowing and sucking strategies can be formulated and adapted according to different motion postures of the underwater vehicle, so that the flow field near the control surface is effectively optimized, the device is suitable for the direct navigation state of the underwater vehicle, the yaw and rotation states of the underwater vehicle, the using effect is good, and the application range is wide.
By adopting the active flow control method provided by the invention, numerical simulation and model experiments show that the maneuvering performance and stealth performance of the X-shaped maneuvering surface underwater vehicle are greatly improved before and after control; within the given test parameter range, the operability index (speed rise rate) of the X-shaped control surface underwater vehicle is improved by 12.5%, and the stealth performance index (flow induced noise of the main frequency band) is reduced by 10dB.
In the actual use process, generally, when the underwater vehicle turns clockwise or yaw to the right, a large amount of fluid is accumulated on the upper surfaces of the four rudders, the lower surfaces of the four rudders are less in fluid, the upper surfaces of the four rudders are subjected to blowing operation, and the lower surfaces of the four rudders are subjected to suction operation; conversely, when the underwater vehicle rotates anticlockwise or yaw to the left, the upper surfaces of the four rudders perform suction operation, and the lower surfaces of the four rudders perform blowing operation; thereby leading the rudder surface fluid to be average and uniform and improving the flow field.
As shown in fig. 5 and 6, schematic diagrams of the surface vortex structure of the underwater vehicle before and after the active flow control method is used, which are obtained through numerical simulation. It can be seen that the vortex structure near the tail control surface of the underwater vehicle is effectively controlled after the active control operation of blowing and sucking is adopted. As shown in fig. 5, in the case where active flow control is not used, vortex emission is serious, vortex separation point is early, and the overall strength of the vortex is great; in the case of active flow control, vortex shedding is controlled, the vortex separation point appears to shift, and the overall strength of the vortex is also reduced, as shown in fig. 6. Therefore, the maneuvering performance and the stealth performance are improved, and the effectiveness of the flow active control method is verified.
The invention effectively improves and optimizes the flow field around the control surface through active operation, and achieves the purposes of improving the rudder efficiency of the control surface and reducing the flow-induced noise, thereby greatly improving the maneuvering performance and stealth performance of the underwater vehicle.
The above description is intended to illustrate the invention and not to limit it, the scope of which is defined by the claims, and any modifications can be made within the scope of the invention.
