美海军研制雷达诱饵无人航空器

美国海军研究实验室正在研制一种小型无人航空器,称为“福莱特”(Flyrt,FlyingRadar Target),它可以用北约标准的箔条发射器发射。这种     

用于核动力攻击潜艇的全综合容错(FIFT)指挥、控制、通信和测量(C~3I)系统

目前,美国实用的潜艇用电气和电子系统设计实际上是彼此独立的。这样的实践限制了利用过去几十年所获得的技术进步的优点。为了使潜艇平台的能力最大化,必须综合传统的、具有类似处理和通信要求的各个系统。本文研究和分析一种可能的称之为FIFT C~3I系统的实现,该系统综合支援潜艇任务的所有主要的电气和电子系统。这样的系统必须有容错能力,以致于使综合系统的可靠性、可用性和安全性等于或优于要替换的现有系统。这种方法的优点很多且可用现有技术和部件实现。     

村民兵连长兼职的利与弊

在市场经济形势下,如何加强和改进村级民兵组织建设,笔者对资阳市33个村民兵连长由村支部书记和村副主任兼任的利弊作了如下调查: 一、村支书或村副主任兼任民兵连长的有利因素 1.减少了村干部人数,提高了村干部的待遇。原村干部由支书、村主任、副主任、民兵连长、妇女主任、团支部书记、会计等人组成。如今他们改为由村支书(兼民兵连长)、村主任(兼治安)、副主任、妇女主任     

乡镇专武干部老化与退伍军人安置难的现状及对策

最近,笔者就四川内江市3个县(市)的乡镇专武干部老化与城市退伍军人安置难问题做了一番调查。 乡镇专武干部的现状是: 一、年龄过大。3个县共有243名专干,44岁至57岁的占总数的24.5％;40岁至42岁的占46.5％;39岁以下的占29％。 二、文化程度普遍偏低。243名专干中,大

Aerial multi-spectral AI-based detection system for unexploded ordnance

Unexploded ordnance(UXO) poses a threat to soldiers operating in mission areas, but current UXO detection systems do not necessarily provide the required safety and efficiency to protect soldiers from this hazard. Recent technological advancements in artificial intelligence(AI) and small unmanned aerial systems(sUAS) present an opportunity to explore a novel concept for UXO detection. The new UXO detection system proposed in this study takes advantage of employing an AI-trained multi-spectral(MS...     

High-Velocity Projectile Impact Behaviour of Friction Stir Welded AA7075 Thick Plates

In this study, high velocity impact behaviour of friction stir welded AA7075-T651 25 mm thick plates were investigated using a 7.62 mm × 51 mm lead core and 7.62 mm × 39 mm steel core projectiles. Prior to ballistic trails, mechanical and metallurgical properties of friction stir welded AA 7075-T651 25 mm thick plates were studied. Microstructural and hardness studies revealed that friction stir welds constituted three distinct regions namely Weld Nugget(WN), Thermo-Mechanically Affected Zone(TM...     

Burning rate analysis of laser controlled 5-aminotetrazole propellant

As an innovative propulsion technique, laser augmented chemical propulsion(LACP) seems superior to the traditional ones. However, the corresponding combustion theories have still to be ascertained for LACP. Burning rate of 5-aminotetrazole(5-ATZ) propellant has been studied by testing pressed samples under different combustor pressures and laser powers. Based on micro computed tomography(Micro CT),an advanced thickness-over-time(TOT) method to characterize the regression of the produced nonplana...
