汲取无人机发展经验指导地面无人装备发展建设

军用无人机在实战中的成功应用和陆军较高的作战伤亡比重使得陆军发展地面无人装备的愿望和需求越来越强烈,但当前军用地面无人装备还处于发展的初期阶段,仍未形成完善的作战体系。本文针对如何促进军用地面无人装备发展和建设,加快战斗力生成,提出借鉴军用无人机成熟的发展经验来指导地面无人装备发展和建设的思路,首先论述了无人作战将成为未来战争主要样式的原因,然后简要归纳了军用无人机的发展经验,最后论述了如何根据军用无人机的发展经验来指导地面无人装备发展和建设,希冀这些建议能够为军队地面无人装备的发展建设提供一定参考。     

合成旅实战化装备保障能力问题与对策研究

军队的"跨越"系列实兵对抗演习存在保障人员在战场抢修装备时处置困难、难以在恶劣的战场环境中展开保障作业、器材补给不能精确送达抢修现场以及指挥控制偶尔失控等现象,战场装备也存在故障率高、维修保障难度大的实际情况。本文针对军队装备保障力量发展不均衡、保障分队自我保障存在不足、人才储备不强方面的影响,高温、潮湿、风沙、高海拔等周边环境的影响,器材筹措效率高低、器材储供管理的好坏、器材利用率高低的影响以及指挥控制链路关系、感知战场态势、控制战场节奏的影响四个方面存在的问题,从固强补弱装备保障力量、积极适应战场周边环境、优化器材储供管理和筹措渠道、提高装备保障指挥控制能力等方面着手,结合演训地区实际装备保障存在的矛盾问题进行梳理和思考,探索和研究实战化训练中装备保障的对策措施,以期为部队实战化装备保障提供借鉴。     

Effects of total pressures and equivalence ratios on kerosene/air rotating detonation engines using a paralleling CE/SE method

In this paper, the kerosene/air rotating detonation engines(RDE) are numerically investigated, and the emphasis is laid on the effects of total pressures and equivalence ratios on the operation characteristics of RDE including the initiation, instabilities, and propulsive performance. A hybrid MPI + OpenMP parallel computing model is applied and it is proved to be able to obtain a more effective parallel performance on high performance computing(HPC) systems. A series of cases with the total pressure of 1 MPa, 1.5 MPa, 2 MPa, and the equivalence ratio of 0.9, 1, 1.4 are simulated. On one hand, the total pressure shows a significant impact on the instabilities of rotating detonation waves. The instability phenomenon is observed in cases with low total pressure (1 MPa) and weakened with the increase of the total pressure. The total pressure has a small impact on the detonation wave velocity and the specific impulse. On the other hand, the equivalence ratio shows a negligible influence on the instabilities, while it affects the ignition process and accounts for the detonation velocity deficit. It is more difficult to initiate rotating detonation waves directly in the lean fuel operation condition. Little difference was observed in the thrust with different equivalence ratios of 0.9, 1, and 1.4. The highest specific impulse was obtained in the lean fuel cases, which is around 2700 s. The findings could provide insights into the understanding of the operation characteristics of kerosene/air RDE.     

Effect of metal powders on explosion of fuel-air explosives with delayed secondary igniters

In order to improve the energy level of fuel air explosive(FAE) with delayed secondary igniters, high energetic metal powders were added to liquid fuels mainly composed of ether and isopropyl nitrate. Metal powders' explosive properties and reaction mechanisms in FAE were studied by high-speed video, pressure test system, and infrared thermal imager. The results show that compared with pure liquid fuels, the shock wave overpressure, maximum surface fireball temperature and high temperature duration of the mixture were significantly increased after adding high energetic metal powder. The overpressure values of the liquid-solid mixture at all measuring points were higher than that of the pure liquid fuels. And the maximum temperature of the fireball was up to 1700 ℃, which was higher than that of the pure liquid fuels. After replacing 30％of aluminum powder with boron or magnesium hydride, the shock wave pressure of the mixture was further increased. The high heat of combustion of boron and the hydrogen released by magnesium hydride could effectively increase the blast effect of the mixture. The improvement of the explosion performance of boron was better than magnesium hydride. It shows that adding high energetic metal powder to liquid fuels can effectively improve the explosion performance of FAE.
