Research On Multi-Aircraft Cooperative Attack Mode Under Distributed Layout Of UAV Attack And Reconnaissance

Modern weapon systems are moving toward automation,intelligence,and lethality.Wars are becoming more intense,cruel,changeable,destructive,and more expensive.The threat of warfighters' lives in war is also more Big.Under the premise of this demand,all kinds of unmanned combat platforms have become the hotspots of national research and become the high-tech weapons and equipment that perform the most dangerous operations on the battlefield.At present,all kinds of unmanned vehicles are developing rapidly,but how to combine unmanned vehicles with battlefield reconnaissance and firepower is a difficult point in current unmanned combat research.In the background of the UAV cluster combat mode,the 12.7mm chain machine gun is used as the main combat unit,which can cover the effective kill radius of 1500 m.Firstly,the overall scheme design of the system is completed by examining the split layout.The spatial positioning technology of multi-machine under distributed layout,through the principle of pseudo-distance differential positioning,establishes coordinate transformation models of multiple coordinate systems such as unmanned carrier,weapon platform,photoelectric tracker,ground platform and attack target,through coordinate calculation and Simulation analysis,the error range is concentrated between 0.114-0.14 m.Secondly,the particle outer ballistic calculation model and the six-degree-of-freedom rigid ballistic calculation model are established.The Monte Carlo method is used to calculate the firing spread of the weapon system,and the hit probability of the typical target is analyzed.The analysis shows that when the radio frequency is 450 rounds/minute,the projectile When the initial velocity is 820m/s,when the four platforms cooperate against the target,the hit probability of the eight bursts can reach 0.9734.Finally,the shooting control system and the following system of the UAV under the weapon were designed,and the prototype and test verification were developed.The theoretical research and simulation analysis method are used to construct the combat mode of UAV cooperative attack and reconnaissance under distributed layout,which provides a way of thinking for the follow-up research of multi-machine cooperative combat platform.
