Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of two -dimensional trajectory correction fuse detection, specifically, two -dimensional trajectory correction fuse ground detection system. BACKGROUND

[0002] The concept of two-dimensional trajectory correction fuse was first proposed by Sanders Associates in the mid-1970s. The United States began related technology research in the 1970s and developed technology from one-dimensional correction to two-dimensional correction. Currently, two-dimensional trajectory correction fuse technology has formed equipment and is used in actual combat abroad, while domestically it is in the stage of technology research and integration verification, but breakthroughs have been made in overall design, trajectory measurement, angle control and integration verification.

[0003] Two-dimensional trajectory correction fuse is a technology that integrates two-dimensional trajectory correction function in the fuse of ammunition to improve the accuracy of ammunition. This fuse can measure trajectory parameters in real time during the flight of the projectile and make trajectory correction according to the measurement results, thereby improving the shooting accuracy.

[0004] Two-dimensional trajectory correction fuse is suitable for various scenarios that require high-precision shooting, such as military strikes and precision strike missions. Its advantages include:

[0005] ‌Low cost and high efficiency‌: Compared with traditional precision guided weapons, two-dimensional trajectory correction fuse has lower cost but higher precision;

[0006] ‌High reliability‌: Due to the absence of complex rudder transmission structure and fewer moving parts, it has high reliability;

[0007] ‌Flexible use‌: Only the target position parameters need to be loaded into the fuse before launch to achieve accurate hitting;

[0008] However, there are limited detection methods for the gyroscopes inside two-dimensional trajectory correction fuses. Usually, only precision detection is performed when the gyroscope is shipped, and it is difficult to measure after the gyroscope is installed. Even if it is measured, it can only be measured individually, which is low in detection efficiency, making it difficult to guarantee the precision requirement during the use of two-dimensional trajectory correction fuse. Utility model content

To overcome the defects of the above prior art (or related technology), the utility model provides a two-dimensional trajectory correction fuse ground detection system.

[0021] In a possible implementation, the control module is further connected with at least one serial screen, so that an operator can input an execution instruction to the control module to control starting of the first driver and the second driver.
