Blasting Height Control Method of Millimeter Wave Proximity Fuze for Tank Gun Based on Data Setting
In order to meet the requirements of striking the personnel,armor,covered and other targets,the millimeter wave proximity fuze for tank gun needs to have a variety of blasting heights to maximize the projectile damage efficiency.It is difficult to meet the multiple blasting heights of proximity fuze due to the low ballistic extension of tank gun and the narrow beam of millimeter wave detector.A blasting height control model of millimeter wave proximity fuze for tank gun based on setting delay is established,and the strategy for increasing the ignition delay is analyzed to achieve the blasting height control.The ignition delay is calculated according to the initial firing angle and other attack conditions before launching,and the information crosslink between the weapon platform and the projectile is used to set the firing delay to the proximity fuze,so as to realize the blasting height control of projectile.A mathematical model is established,and the relationships among ignition delay,projectile initial velocity,firing angle,beam width of millimeter wave detector,detection distance and blasting height difference are analyzed by simulation.The calculation formula of ignition delay is summarized.The validity of the proposed method is verified by static test in laboratory and dynamic test in field.
