Description

Technical Field

[0001] The utility model relates to the technical field of product simulation detection, in particular to a simulation test device for an initial velocity measuring device. Background Art

[0002] Measuring flight information, such as projectile muzzle velocity and trajectory, is one of the most fundamental parameters in artillery range testing and a fundamental indicator of artillery performance. Therefore, using ammunition training support monitoring equipment to accurately and promptly reproduce flight information, such as the trajectory and muzzle velocity of rapidly flying projectiles across a vast range, for researchers or observers is essential equipment at the range.

[0003] As a common piece of equipment at the range, ammunition training support and monitoring equipment is used frequently. To ensure test accuracy, these equipment require regular calibration. New equipment received at the range typically requires a joint test run and calibration between the customer and the manufacturer.

[0004] The existing verification method uses ammunition training and monitoring equipment commonly used at shooting ranges and calibrated artillery. During live-fire firing, the ammunition training and monitoring equipment, commonly used at shooting ranges, collects muzzle information to obtain the projectile's trajectory and initial velocity.

[0005] Using actual equipment for all debugging and testing would significantly inconvenience the debugging process during the development of new ammunition training support and monitoring equipment. This would also be extremely inconvenient for future performance testing during the manufacturing and acceptance process of ammunition training support and monitoring equipment. In particular, actual equipment testing requires the cooperation of troops, the mobilization of personnel and equipment, and is time-consuming and complex to coordinate. Therefore, it is necessary to design a projectile muzzle velocity simulation device for testing new ammunition training support and monitoring equipment. Utility Model Content

[0046] The utility model realizes the simulation of the initial velocity of a projectile of 30-2000 m / s by adjusting the lighting time of LED1 to LED54.

[0047] The muzzle flash module uses a 300x300mm rectangular aluminum alloy housing with an internal LED and a parchment-covered front panel. The projectile velocity module uses a 1000x40m rectangular aluminum alloy housing with an internal LED and a parchment-covered front panel.
