抗空间碎片碰撞穿透的航天器加强防护板设计

文章描述了以整体薄护罩和等效重量波纹薄护罩制作的双层板结构系统穿孔阻力的研究结果。指出如果以等效重量波纹缓冲器代替整体缓冲器可以显著地增加穿孔防护能力。针对在倾斜超高速碰撞事件中跳飞碎片的产生,波纹薄护罩的波纹参数可以用减少势的方法优化。

数字式射击瞄准计算机设计与实现

某型射击军械系统的射瞄计算机原采用模拟机电式技术实现,存在体积大、功耗大、可靠性及可维护性差等缺点,因此,使用数字式计算机技术对其进行升级改造势在必行.本文首先对原系统的火控原理及火控构型的进行了分析;其次,介绍了射击瞄准计算机的对外接口关系.重点介绍了数字式射击瞄准计算机的采样解算时间的确定、计算方法的选取及接口设计等内容.本文所设计的数字式射击瞄准计算机已通过了系统验证并得到了使用,克服了原有系统所存在的固有缺点.文中的设计思想与所用的工程方法对类似武器系统的升级改造有所借鉴.     

Reconstructed 3-d magnetic field structure and hard X-ray two ribbons for 2000 Bastille-day event

The Bastille-day event in 2000 produced energetic 3B/X5.6 flare with a halo CME, which had great geo-effects consequently. This event has been studied extensively and it is considered that it follows the two-ribbon flare model. The flare/CME event was triggered by an erupting filament and TRACE observations showed formation of giant arcade structures during the flare process. Hard X-ray (HXR) two ribbons revealed for the first time in this flare event (Masuda et al., 2001). The reconstruction of 3-D coronal magnetic fields revealed a magnetic flux rope structure, for the first time, from extrapolation of observed photospheric vector magnetogram data and the flux rope structure was co-spatial with portion of the filament and a UV bright lane (Yan et al., 2001a, 2001b). Here we review some recent work related to the flux rope structure and the HXR two ribbons by comparing their locations and the flux temporal profiles during the flare process so as to understand the energy release and particle accelerations. It is proposed that the rope instability may have triggered the flare event, and reconnection may occur during this process. The drifting pulsation structure in the decimetric frequency range is considered to manifest the rope ejection, or the initial phase of the coronal mass ejection. The HXR two ribbons were distributed along the flux rope and the rope foot points coincide with HXR sources. The energy dissipation from IPS observations occurred within about 100 R _⋅ is consistent with the estimate for the flux rope system. This revised version was published online in August 2006 with corrections to the Cover Date.
