Embodiment 1

[0042] In this first embodiment, a light torpedo sound conductor guide is described.

[0043] like figure 1 with figure 2 As shown, the light torpedo acoustic guide device includes a guide head 1 and a transducer basis.

[0044] Among them, the guide header 1 uses a flat-top structure, that is, the front end surface of the guide header 1 is a circular plane 2 having a relatively small diameter. The rear end of the guide head 1 is an electronic bin 3, and the electronic bin 3 is opposed to the diameter. A larger cylindrical structure.

[0045] A transition section 4 is disposed between the front end surface of the guide header 1 and the electronic bin 3, wherein the transition section 4 uses a streamlined arc segment.

[0046] The transducer base array includes a front end face plane array 5 and a side sparse circular peripheral array 6.

[0047] Among them, the front end face plane array 5 includes a plurality of transducer matrix elements arranged on the front end surface of the ...

Embodiment 2

[0065] In this first embodiment, a light torpedo acoustic guidance device is different from that of the above-described embodiment 1, and the remaining technical features can be refer to the above-described Embodiment 1.

[0066] like image 3 As shown, in order to avoid the influence of the flow noise on the transducer matrix as much as possible, the second embodiment change the arrangement of the side sparse circumference, which is about the side of the circular array 6 in each transducer matrix 8 The cylindrical segment (i.e., electronic warehouse 3) placed on the transition section 4 of the flow line arc transition section.

[0067] In this case, the transducer module 8 is placed in the circumferential direction, and the transducer matrix element 8 is large in the circumferential direction, and the direction of the transducer matrix 8 is guided by the light torpedo. The cylindrical axis direction is perpendicular.

Embodiment 3

[0069] In this Example 3, a light torpedo sound guidance method was provided, which is based on the light torpedo torrent guidance device in Example 1 or in Example 2 to meet the guidance needs of light torpedoes in different task stages.

[0070] like Figure 4 As shown, a light torpedo sound guidelines are included, including the following steps:

[0071] Step 1. Light fish thunder into the water stage, light torpedo large angle into the water, the side is sparse around the circumference of the circle, and the surrounding situation of the torpedo, and the goal is approximately determined at the time of the target, the search results are received before the launch of the torpedo. The initial instruction of the target passes through information, and the general spatial orientation of the torpedo steering target is controlled by the integrated control system.

[0072] Step 2. In the initial phase of the light torpedo navigation, the purpose is to search for the target and confirm th...

Abstract

The invention belongs to the technical field of self-guiding engineering of torpedo science, and discloses a light torpedo acoustic guiding device. The device comprises a guiding head and a transducer array. The front end face of the guide head is a circular plane; an electronic bin is arranged at the rear end of the guide head and adopts a cylindrical structure; the diameter of the front end face of the seeker is less than that of the electronic bin; A transition section is arranged between the front end face of the guide head and the electronic bin; the transition section adopts a streamline arc section; the transducer array comprises a front end surface planar array and a side sparse circumferential array; the front end surface planar array comprises a plurality of transducer array elements which are arranged on the front end surface of the seeker and are arranged according to a symmetry principle; the side edge sparse circumferential array comprises a plurality of transducer array elements which are arranged in the circumferential direction of the transition section at equal intervals, and all the transducer array elements in the side edge sparse circumferential array face forwards. According to the invention, the transducer array is optimized and compactly arranged, so that the maximum space gain can be fully obtained in the limited volume space of the small-caliber acoustic guiding device.

Description

Technical field [0001] The invention belongs to the technical field of self-guided engineering techniques of fish thunder, and is particularly related to a light torpedo-torpedo guidance device, and a light torpedo-torpedo guidance method based on the light torpedo acoustic guidance device. Background technique [0002] When the torpedo works mainly through the guidance device to detect the target, after the signal is amplified, after calculation, the relative positional relationship between the torpedoes and the target is calculated, and then the triangle is subjected to the attack trajectory, pass the signal to the control system to The rudder face controls the torpedo motor trajectory to attack the target. Therefore, the guiding device is the earpiece of torpedo in underwater, and the fish thunderous guidance device is automatically formed by the acoustic energy of the target, which automatically forms a system, active, passive and main passive joint three. A way. The active a...
