23、Trend</p><p>  Artillery and ammunition from the patrol's history and current status of development can be seen, it is a kind of information-based product of war. Only when the army's request for inf

24、ormation to the more important than ever today, there will be patrols of ammunition, and artillery as a repressive force, patrolling its development of the corresponding ammunition is essential. In the guided artillery s

25、hells, unmanned aerial vehicles, sensors, such as the progressive development and improvement of</p><p>  The so-called intelligence, referring to their own artillery ammunition patrol operations to complete

26、 multiple tasks, both targets of the battlefield reconnaissance, surveillance, but also the completion of battlefield damage assessment operations. From the development of artillery ammunition patrol the status quo can b

27、e seen that the function of artillery ammunition patrols mainly reconnaissance, surveillance, and assessment tasks. Patrol in the use of ammunition have been taken after the end o</p><p>  The so-called smar

28、t, and refers to the patrol artillery guns and ammunition to match a variety of delivery systems. The development of artillery ammunition patrol did not change in the existing artillery fired based on the platform, from

29、the artillery and ammunition Research patrols can be seen that the requirements of its current artillery systems compatible at the same time, but also hope that it is able to meet Some variety of artillery systems, this

30、can greatly reduce the use of artillery am</p><p>  Of the so-called low-cost means to patrol the emergence of ammunition, in a sense, because it is both conventional weapons and reconnaissance UAV's abi

31、lity to reduce the development of weapons systems and the use of the cost, but nevertheless, and now countries in the development of artillery radio patrol the course of ammunition are to seek the use of a variety of new

32、 low-cost materials. Information from existing reports can be summed up to reduce the cost of artillery ammunition, patrol the ma</p><p>  3 The Key Technologies</p><p>  Patrol artillery ammu

35、technologies.</p><p>  1) the overall multi-disciplinary design optimization techniques</p><p>  Ammunition as a result of patrols be considered in the design of body shape structural optimizati

36、on design, the module body optimize the matching function, quality and fuel payload to achieve the best ratio, aerodynamics and stealth properties of a range of issues, so this is a between the many disciplines involved

37、in the optimal design. Cross-coupling between the disciplines and the impact of the decision of the patrol ammunition is designed to be a problem of complex systems science.</p><p>  At present, an increasin

45、ions</p><p>  In the previous mentioned trends, patrol ammunition intelligent design is moving in the direction of development, which requires it to fly round the track planning; At the same time able to do

46、more than patrol to communicate with each other between rounds to ensure that work together to avoid duplication of reconnaissance and attack. Ammunition were also required to patrol their own situation based on real-tim
