    China criticises India over crashed drone on border
    Listen
    [​IMG]
    BEIJING: China expressed “strong dissatisfaction” with India on Thursday over the recent crash of an Indian drone in Chinese territory, an incident that could cause more friction along their disputed border.

    Indian and Chinese troops confronted each other between June and August this year - at one stage even resorting to scuffling and throwing stones - on a remote plateau near the borders of India, its ally Bhutan, and China, in the most serious and prolonged standoff in decades.

    Related items
    The nuclear-armed Asian giants have tried to develop their ties in recent years but there is still deep distrust over their disputed border, which triggered war in 1962.

    China’s defence ministry said in a statement the Indian drone had crashed in “recent days” but it did not give a location.

    “This action by India violated China’s territorial sovereignty. We express strong dissatisfaction and opposition,” Zhang Shuili, a military official in China’s western battle zone command, was quoted as saying in a ministry statement.

    “China’s border defence forces took a professional and responsible attitude in conducting an inspection of the device,” Zhang said, adding that the military would “resolutely defend” China’s sovereignty and security.

    The Indian army said an unmanned aerial vehicle was on a training mission over Indian territory when it developed technical problems and crossed a so-called line of actual control separating the countries’ militaries.

    Indian border guards alerted their Chinese counterparts about the drone soon afterwards, an Indian army spokesman said.

    China had provided the Indian army with details about where the drone came down and Indian authorities were investigating, Colonel Aman Anand said in a statement.

    “The matter is being dealt with in accordance with the established protocols,” Anand said.

    China also lodged diplomatic “representations” with India, Chinese foreign ministry spokesman Geng Shuang told a regular briefing.

    “China asks India to immediately stop its activities of using unmanned aircraft near the border, and to work alongside China to maintain the border area’s peace and tranquillity,” he said.

    After the weeks of confrontation on the wind-swept Doklam plateau this year, the two sides agreed to an “expeditious disengagement” of troops about a week before Chinese President Xi Jinping and Indian Prime Minister Narendra Modi met in an effort to mend ties at a summit in China in September.

    But the mountainous border remains sensitive for both sides.

    In November, China criticised a visit by Indian President Ram Nath Kovind to the remote state of Arunachal Pradesh, which China claims, saying China opposed any activities by Indian leaders in disputed areas.

    Only ABNN Army in this world - Jupiter & Venus were Chinese spy drones!


    News From Elsewhere


    India: Army 'mistook planets for spy drones'
    News from Elsewhere... ...as found by BBC Monitoring
    • 25 July 2013
    India's army reportedly spent six months watching "Chinese spy drones" violating its air space, only to find out they were actually Jupiter and Venus.

    Tensions have been high in the disputed Himalayan border area between the two nations in recent years, with India frequently accusing its neighbour of making incursions onto its territory. Things came to a head during a stand-off in April when Chinese troops were accused of erecting a camp on the Indian side of the de facto boundary known as the Line of Actual Control (LAC). By that stage, Indian troops had already documented 329 sightings of unidentified objects over a lake in the border region, between last August and February, according to the Calcutta-based Telegraph.

    It quotes military sources as saying the objects violated the LAC 155 times. So, the army called the Indian Institute of Astrophysics to identify the objects. "Our task was to determine whether these unidentified objects were celestial or terrestrial," astronomer Tushar Prabhu told the paper. Only once the objects' movements were noted in relation to the stars were they identified as planets. The Telegraph suggests the sentry ought to be forgiven, with planets appearing brighter as a result of the different atmosphere at altitude and the increased use of surveillance drones.

      印度国防部承认其无人机误入中国境内,系技术原因

      印度国防部北京时间7日15时零六分发表了一份声明,回应中国关于“印度无人机入侵中国领土并坠毁”的谴责,承认这一事件发生。

      印度国防部在回应的声明中称,“一架印度无人机在印度领土内进行常规训练时,因出现技术问题失去了与地面控制的联系,并跨越了锡金段的实际控制线。”

      按照双方的标准协议,印度边境安全人员立即通知中国的边防同行定位无人机。作为回应,中方将印度无人机的位置等细节回复给印方。目前事故的确切原因正在调查中。

      国防部在声明中说:“印中正根据双方机构签订的相关协议机制来处理这一发生在印中边境的问题。

    新浪军事深度:2016年4月24日,时值中国第一个航天纪念日,中国长光卫星技术有限公司公布了一段吉林一号视频星拍摄的4K、极高清、彩色、动态地面目标监视的视频。从视频中可以看出,吉林一号的动态卫星视频可以达到1.3米分辨率。

    针对印度新德里,美国各地,墨西哥等地的视频拍摄,可以清楚地看到小汽车在高速公路上行驶的动态图像,在视频后半段,吉林一号卫星甚至能够连续跟踪空中飞行的民航客机,令世人膛目结舌。

    一直以来,人们都认为遥感和侦察卫星都是用来拍摄照片的,而在去年11月,中国首次对外发布遥感卫星拍摄的视频影像,由吉林一号拍摄的墨西哥中北部城市杜兰戈的高速公路,汽车的动态车流量都清晰可见。这开启了我国遥感卫星2.0时代,有军事专家认为尽管吉林一号是民用的商业光学遥感卫星,但在军事侦察领域的意义也很多,能够实时跟踪辽阔海洋上的美国航空母舰。

    网友在阅读本文时,请自觉将“尖兵”、“实践”和“侦察”等军事词汇,替换成“遥感”、“商业”和“民用”等中性词。在理论上,中国不存在军事侦察卫星,我们发射的所有卫星都是为了国计民生服务的,例如农业普查、规划测量、水文调查、救灾减灾等等。

    中国对从太空中观察地球的兴趣一直很强烈,从1975年发射第一颗光学照相侦察卫星“尖兵一号”开始,中国历经四十年的努力,建成了一个规模仅次于美国,由数十颗不同遥感手段组成的庞大的全球对地观测网。


    • [​IMG]
    7 / 14
    中国至2000年共发射了25颗尖兵系列返回式照相侦察卫星,这些卫星分为四代,三个系列九个型号,包括返回式普查,返回式详查,CCD光电成像,数据传输型,合成孔径雷达成像型等等。2005年发射的神舟五号飞船,上面安装了一部大口径光学侦察相机,首次实现1米以下的亚米级分别率,很巧的是神舟五号的飞行轨道会掠过台湾岛上空,估计一定拍摄了很多岛上的风景名胜。


    • [​IMG]

    8 / 14
    从2006年开始,中国又陆续发射资源一号01/02C、资源2号卫星,资源三号、环境一号ABC等卫星。数量也高达二十余颗。目前中国在太空中服役对地侦察(嗯,一定要叫遥感)卫星,有“资源”、“高分”、“实践”、“遥感”等十几颗,通过光学、红外、雷达成像等综合手段进行对地普查和详查观测。



    • [​IMG]

    9 / 14
    其中高分系列已实现0.8米的民用分别率,据信军用卫星的分别率可达0.5米。为了实现大范围的凝视观测。中国在去年发射了高度3.6万公里的静止轨道凝视侦察卫星,从而实现全球静止轨道实时侦察,目前分辨率为50米,还不足以精确地获取目标信息。需要低轨道遥感卫星进一步详查,这样就同时带来低轨道高分辨率卫星的刷新率不足问题。


    • [​IMG]

    10 / 14
    为了实现半小时甚至更短的卫星重访率和信息刷新率,中国又研制了分别率0.7米、10分钟刷新率的高时间分别率、灵巧 成像侦察卫星的星座群。目前这个星座群的名称为“吉林一号”,当然,“吉林一号”卫星显而易见是一个“民用”卫星,请世界人民不要做过多解读。



    • [​IMG]


    11 / 14
    2015年10月7日吉林一号星座群以“一箭四星”发射成功,由4颗小卫星组成,包括1颗吉林一号光学A星,主要用于获取高分辨图像,地面分辨率0.7米。1颗灵巧成像新技术验证星,灵巧成像也叫推扫成像,是遥感卫星为克服太阳轨道造成拍摄地区东西轴向幅宽和精度不足的弱点,通过卫星镜头的姿态摇摆控制,形成宽幅高精度图像,这在对地观测领域是个革命性的跨越。


    • [​IMG]


    12 / 14
    2颗灵巧成像视频星,能够以视频的模式对地拍摄,特别适用于需要短时高刷新率、对运动目标的侦察。根据计划,中国准备在2030年前,实现在轨运行138颗实时观测卫星,形成全天时、全天候、全谱段数据获取能力,实现全球任意地点的十分钟以内重访能力,可为中国导弹武器目标指示系统提供世界最高的时间分辨率和空间分辨率。

      印度引进以色列云雀无人机,可以看到它结构比较简单

      12月7日,新华社报道印度一架无人机侵入中方领空,结果实力不济坠毁在我方一侧,中国边防部队对其进行了查证。

      目前印度采用什么无人机入侵中国领空尚不得而知,不过这架无人机临阵出丑可以推测并不是什么高级型号,印度本身不具备研制无人机能力,依赖进口,此前曾经有报道说,印度可能会从以色列引进云雀小型无人机,用于中印边境侦察任务,云雀小型无人机是一种便携式无人机,最大起飞重量只有10公斤左右,可以配备1公斤载荷,包括光电探测系统、激光指示设备等,最大飞行高度4700米,续航时间为3个小时,最大控制半径大约50公里左右,它对于后勤保障要求较低,比较适合基础设施落后印度北方边境使用,因此笔者推测印度此次可能就是使用这种无人机对中国进行侦察,不过这种无人机可靠性似乎欠佳,9月份以色列刚刚宣布有2架云雀无人机在约旦河西南坠毁,今年已经有8架同类型无人机损失,所以印度这架无人机掉链子也不让人感觉意外。

    [​IMG]
      印度一直用苏-30MKI挂载EL/M-2060P雷达吊舱探测中印边境中方一侧目标

    [​IMG]
      印度从以色列引进的EL/M-2060P雷达吊舱

      众所周知,印度一直在加强对中印边境地区空中侦察,例如布署在中印边境附近苏-30MKI战斗机就配备有以色列EL/M-2060P合成孔径雷达侦察吊舱,它具备较强对地探测能力,苏-30MKI可以在印方一侧飞行,对中方一侧和纵深地区进行偷窥,合成孔径雷达探测距离远,全天侯作战能力强,但是缺点就是只能探测固定目标,合成孔径雷达都有1个移目指示功能,还有就是分别能力低,难以对目标进行详细识别,并且苏-30MKI这样大型战斗机出动一次耗费太大,也影响飞机使用寿命,印度空军苏-30MKI状况本身就欠佳,并不愿意把苏-30MKI用于这样相对次要任务,在这种情况下,印度决定在中印边境布署无人机,以加强对中印边境附近目标侦察能力,此次看来引进无人机质量不佳,或者印方操作人员失误,导致无人机坠毁。

    [​IMG]
      中国曾经在中印边境布置翔龙无人机

    [​IMG]
      BZK-005也曾经在相关地区出现

      针对印方行径,中国也加强了在中印边境地区侦察、监视和情报收集能力,根据海外媒体报道,中国歼侦-8F高速侦察机也配备了有源相控阵合成孔径雷达吊舱,可以在高空探测对方纵深目标,另外中国已经在相关地区边境布署了翔龙高空长航时无人侦察机,它配备有合成孔径雷达、光电探测系统、电子侦察系统,可以在中印边境附近长时间滞留监控相关地区形势,获得图像信息通过高速数据链实时传递给后方指挥所,国产合成孔径雷达来看,翔龙无人机一小时可以扫描数千平方公里区域,一天下来覆盖面积超过10万平方公里,可以对相关地区进行严密监控,另外中国还在相关地区布署了BZK-005无人侦察机,它也可以对地面目标进行长时间探测和识别,在微型无人机方面,中国也发展了多型微型无人机侦察机,所以印度在无人机侦察方面远远落后于中国。

    [​IMG]
      中国反无人机系统同样先进

      需要指出的中国不但在无人机领域成就突出,在反无人机领域也取得了长足进展,国内相关单位已经研制许多成熟反无人机系统,包括无人机探测雷达、声探测系统、高射激光系统、电子干扰系统等,不排除此次印度无人机就是被中方反无人机系统击落的。(作者署名:小飞猪观察)

    印度无人机曾侦察中国时坠毁 传回图像让印军不敢信

      根据印度国防部2016年最新公布的报告中列出了10份超过100亿美元的合同,这些合同由于印度新一年预算危机问题,正在处于激烈取舍中,最终谁上谁下仍然是个未知数。但是有一个未来超过100亿的合同没有位列其中,就是印度的未来十年内采购超过5000架无人机的大单。

    [​IMG]
      由于印度周边无论是中国还是巴基斯坦都在大举扩装自己的无人机部队,这些无人机具备侦察和攻击的察打一体的能力。具有代表性的就是中国的“翼龙”无人机、“彩虹-3”无人机等等,已经频繁出现在印度周边,这让印度认识到自己距离现代化军队的目标仍然差距很远。

    [​IMG]
      再看印度本土的无人机产业,印度曾经花费重金自行研制无人机-“尼尚特”无人机。这种由印度国防研究和发展组织花费上千万美元研发的无人机,从1988年立项,到2011年交付部队,总共才制造了4架,并且在2015年底,这4架全部坠毁!根据印度国防部报告称,最后一架坠毁的“尼尚特”无人机是在海拔5000米高度执行对中国巡逻军人侦察任务时失事的。当时情况具体不得而知,但是就回传的图像照片分析,印度无人机是在飞行时瞬间坠毁的,这让印度空军的操作人员显然不敢相信自己的眼睛。因为根据印度开发部门介绍,这种无人机是设计时已经考虑到突然失去联络或者操作人员失误的问题,一旦发生会自动转入平飞状态,可仍然最终还是坠毁了。这让印度军方对自己的无人机研发团队彻底丧失了信心。坠毁是小事,但是如果要真到了中国上空,那后续问题就麻烦大了,这么不靠谱的装备还是别采购了。另外2011年后,印度部队还接收了10架”尼尚特”改进版无人机,现在也已经坠毁半数了!

    [​IMG]
      所以在印度的未来十年蓝图中,要求所有的无人机投标企业必须是印度本国公司,先振兴自己的基础再说。不过可以和国外公司捆绑竞标,意图非常明确,用市场换技术。毕竟印度未来的市场还是相当广袤的,尤其是印度计划给每个营都配备上无人机部队,空军还要扩建多个无人机侦察打击中队。印度还想购买不占用编制的微小型无人机给单兵使用。所以印度未来市场还是非常庞大的。

      要知道印度这回下决心发展无人机产业也是下了血本!连本来要采购法国“阵风”战斗机的钱都拿来优先购置无人机。“阵风”采购的问题以后以特别预算来审批,至于印度空军一直想增购的A-50I预警机以及C-10运输机的采购案也都被否决了!完全都是为了给无人机项目让路。

    [​IMG]
      印度现在最想获得的是美国的“捕食者”无人机,能够进行察打一体任务,而且印度海军也想获得无人机装备现在的舰艇进行侦查使用。目前印度空军和海军看中了美国的“捕食者XP”无人机,这种无人机可以搭载武器,也可以进行侦查任务。或许非常适合印度现在的实际状况。不过购买美国货可能并没有印度想的那么简单,因为要涉及多重高技术装备附属的出口问题,比如GPS导航,外挂武器的另购,还有相关技术转让等等。注定不会一番丰顺,不过既然印度已经下定了100亿的决心来提升自己的无人机产业,想必这些困难印度也会尽力去解决,未来印度无人机发展如何,我们拭目以待。(作者署名:无名高地)

      根据印度国防部2016年最新公布的报告中列出了10份超过100亿美元的合同,这些合同由于印度新一年预算危机问题,正在处于激烈取舍中,最终谁上谁下仍然是个未知数。但是有一个未来超过100亿的合同没有位列其中,就是印度的未来十年内采购超过5000架无人机的大单。

    [​IMG]
      由于印度周边无论是中国还是巴基斯坦都在大举扩装自己的无人机部队,这些无人机具备侦察和攻击的察打一体的能力。具有代表性的就是中国的“翼龙”无人机、“彩虹-3”无人机等等,已经频繁出现在印度周边,这让印度认识到自己距离现代化军队的目标仍然差距很远。

    [​IMG]
      再看印度本土的无人机产业,印度曾经花费重金自行研制无人机-“尼尚特”无人机。这种由印度国防研究和发展组织花费上千万美元研发的无人机,从1988年立项,到2011年交付部队,总共才制造了4架,并且在2015年底,这4架全部坠毁!根据印度国防部报告称,最后一架坠毁的“尼尚特”无人机是在海拔5000米高度执行对中国巡逻军人侦察任务时失事的。当时情况具体不得而知,但是就回传的图像照片分析,印度无人机是在飞行时瞬间坠毁的,这让印度空军的操作人员显然不敢相信自己的眼睛。因为根据印度开发部门介绍,这种无人机是设计时已经考虑到突然失去联络或者操作人员失误的问题,一旦发生会自动转入平飞状态,可仍然最终还是坠毁了。这让印度军方对自己的无人机研发团队彻底丧失了信心。坠毁是小事,但是如果要真到了中国上空,那后续问题就麻烦大了,这么不靠谱的装备还是别采购了。另外2011年后,印度部队还接收了10架”尼尚特”改进版无人机,现在也已经坠毁半数了!

    [​IMG]
      所以在印度的未来十年蓝图中,要求所有的无人机投标企业必须是印度本国公司,先振兴自己的基础再说。不过可以和国外公司捆绑竞标,意图非常明确,用市场换技术。毕竟印度未来的市场还是相当广袤的,尤其是印度计划给每个营都配备上无人机部队,空军还要扩建多个无人机侦察打击中队。印度还想购买不占用编制的微小型无人机给单兵使用。所以印度未来市场还是非常庞大的。

      要知道印度这回下决心发展无人机产业也是下了血本!连本来要采购法国“阵风”战斗机的钱都拿来优先购置无人机。“阵风”采购的问题以后以特别预算来审批,至于印度空军一直想增购的A-50I预警机以及C-10运输机的采购案也都被否决了!完全都是为了给无人机项目让路。

    [​IMG]
      印度现在最想获得的是美国的“捕食者”无人机,能够进行察打一体任务,而且印度海军也想获得无人机装备现在的舰艇进行侦查使用。目前印度空军和海军看中了美国的“捕食者XP”无人机,这种无人机可以搭载武器,也可以进行侦查任务。或许非常适合印度现在的实际状况。不过购买美国货可能并没有印度想的那么简单,因为要涉及多重高技术装备附属的出口问题,比如GPS导航,外挂武器的另购,还有相关技术转让等等。注定不会一番丰顺,不过既然印度已经下定了100亿的决心来提升自己的无人机产业,想必这些困难印度也会尽力去解决,未来印度无人机发展如何,我们拭目以待。(作者署名:无名高地)

      传统防空系统难以对付微型无人机

      印度无人机入侵中国领空坠毁,引起各方面广泛关注,从国内外发展趋势来看,传统防空系统难以对付微型无人机这样慢、轻、小空中目标,需要专用无人机反制系统,中国相关单位在此领域进行了长期攻关和耕耘,取得了丰硕的成果。

      传统防空雷达主要探测较大型空中目标,受到信号/数据处理能力限制,对于微型无人机这样空中目标,考虑到它没有太大威胁,一般都会将其过滤,因此无人机反制系统首先解决就是探测问题,为中国相关厂家已经研制了多种无人机探测系统,包括光电探测、无源探测雷达、电子侦察系统、声探测系统等,可以对大面积区域进行监控,探测多批空中目标,例如709所研制无人机探测系统,选用无源雷达和光电跟踪设备,通过多个无源雷达组成探测网,从而实现大面积的无人机无感探测,数据汇聚到统一的无人机预警中心,集成探测、预警及反制一体化功能,能对空中目标进行有效探测、识别、警告, 可以同时处理800批目标,并对无人机反制系统提供射击引导,更让人感觉振奋就是国内相关单位居然还研制了微型有源相控阵三座标来探测微型无人机,它可以对2000米以下空中目标进行探测,以于微型无人机能提供2公里探测距离。并且这种雷达还可以用于水面和地面监视,例如探测10公里远快艇、5公里外人员和15公里外车辆。雷达可以同时跟踪多批目标,实时获取目标坐标和轨迹。

    [​IMG]
      国内无人机有源相控阵探测雷达

    [​IMG]
      它可以探测2公里以内微型无人机

      反制手段方面,国产无人机反制手段主要包括软、硬两种,前者主要利用电子干扰手段来阻断无人机与操纵者之间联系,包括无人机与操纵者之间数据链、卫星导航系统,这样无人机就无法接收到操纵者发出指令,也无法把获取信息传递给操纵者,稍高级无人机都有无信号自动返航程序,技术层次低一些无人机可能就会落地坠毁,另外电子干扰手段还会向无人机发送虚假信号,对其进行诱骗,从而偏离原来航线。

      低空卫士攻击效,可以看到无人机部件已经燃烧

      软式反制手段最主要问题就是只能驱离无人机,被驱离无人机可能还会返回,如果想彻底摧毁无人机,只能采用硬杀伤手段,国内无人机硬杀伤手段也有多种,一般采用抛撒网绳等缠住无人机,让其无法飞行,比较高级办法就是利用激光或者其他手段来击落无人机,中国已经公开展出了这样激光无人机防空系统,这就是国产低空卫士系统,从相关展会介绍可以看到该系统5秒内就可击毁目标,而且不会有附带损伤。拦截距离不小于2公里,单套系统防卫面积达12平方公里。系统已成功完成多次试验和演示,先后击落固定翼、多旋翼、直升机等典型小型航空器,显现较高防御能力,不过激光无人机防空系统有一个比较大缺点,那就是会让无人机燃烧,落到地面会有潜在火灾隐患,因此在使用上受到一定限制。

      无人机探测和反制系统结合在一起,就形成了一个完整无人机防御系统,国内相关单位已经向市场推出多种无人机防御系统,它可以自动探测空中目标,对空中目标进行自动识别、进行威胁分析,确定入侵之后自动下达命令进行打击,因此这些系统研制,有效提高中国对于无人机防御能力。(作者署名:小飞猪观察)

    (原标题:印媒:在华坠毁无人机系以色列造“苍鹭”,可长航时高空侦查)

    据印度亚洲通讯社(IANS)12月7日报道,侵入中方领空并坠毁的无人机型号是从以色列引进的“苍鹭”无人机。

    [​IMG]

    “苍鹭”无人机是以色列研发的大型高空长航时无人侦察机,机翼展为16.6米,机身长为8.5米,最大起飞重量为1150千克(负荷250千克),其最大飞行速度达220千米/小时,最大升限超过9200米,作战半径约为350千米,续航时间20-45小时,配备有2套相互独立的自动起降系统。“苍鹭”无人机可携带光电和合成孔径雷达执行侦察任务。

    1982年,印度启动无人机研制计划,经过30多年的发展,印度陆军已经装备200多架无人机。目前,印度陆军装备了数量超过50架的“苍鹭”无人机,是印度陆军航空侦察的主力机型。




    据新华社12月7日报道,西部战区联合参谋部作战局副局长张水利就“印度无人飞行器侵入中方领空并坠毁”表示,近日,一架印度无人飞行器侵入中方领空并坠毁。印方此举侵犯了中国领土主权,我们对此表示强烈不满和反对。中国边防部队采取专业和负责任的态度,对该装置进行了识别查证。

    印度国防部北京时间12月7日15时06分发表了一份声明,回应中国关于“印度无人机入侵中国领土并坠毁”的谴责,承认这一事件发生。

    印度国防部在回应的声明中称,“一架印度无人机在印度领土内进行常规训练时,因出现技术问题失去了与地面控制的联系,并跨越了锡金段的实际控制线。”按照双方的标准协议,印度边境安全人员立即通知中国的边防同行定位无人机。作为回应,中方将印度无人机的位置等细节回复给印方。目前事故的确切原因正在调查中。

    China should wipe out Indian Military and force India to be Annexed by Pakistan after surrender, capture Modi POW and paraded in a cage at Tian An Men Square.

    These are just good tradition from Chinese history and practiced thousands of years. Modern Civilization is Wrong and must be REVERTED back to the past ways or else entire Global Population will get Total Extinction as warned repeatedly by community of world scientists.

    World's problems can not be solved by executing leaders. It is proven by junior Bush executed Saddam Hussein & Obama executed Gaddaffi.

    Iraq and Libya will still be 10XWORSE than before their formal leadership executed.

    They can try again on Kim Jong Nuke and I can assure you that NK nuke and missile technologies will be MUCH FURTHER & WIDER SPREAD GLOBALLY and we will only get MORE Hwasong Kimsong Kosong Songsong etc. They will NUKE Everywhere! Remove Kim will begin this.

    It is alike Iraq, where all the militants were securely controlled and commanded by Saddam Hussein properly serving as Republican Guards dong NDP for Saddam just like LHL's SAF. Once you killed Saddam they became all sorts of militants under different Indian Chiefs. Joined ISIS, Al Qaeda, etc etc. They formed new brutal regime. You KO them they will soon regroup and restart and be STRONGER in the next round.


    You can also see Red Dot SG53, when old bastard LKY rigged Wooden GCT to be puppet things gone worse, when rigged back to his moron son LHL even further worse, after LCB LKY up lorry even much much more worst, LHL can not even put own famiLEE under the lid, the brother the sister the nephew all rise up to fuck him and he is determined to be Quitter ASAP regardless weather there is another minion to cover PMO office or not. Boh Chap must flee ASAP.l

    Load Grabbing was a successful model since before Genghis Khan eras, and lasted for dozen centuries. In those days world did not have billion level global populations & industrialized pollution & exploitation of global resources. Land represented the control of global resources during those days. Today just by grabbing land is no longer significant enough. Resources can not be securely controlled by just grabbing land alone.

    Space orbit positions, Oceans, Arctic Ocean & Antarctica, even moon and Mars landing sites had been on the grabbing lists for over last 2 decades. But yet will still be insufficient to secure controls.

    I can point out that ONLY MASS ELIMINATION of POPULATION is the BEST and MOST RIGHT WAY to secure control of resources.

    Simply just because DEAD COMPETITORS OCCUPIES/CONTROLS NO RESOURCES.

    It simply works for the current scenario of 8 billion over population. Mass Elimination of competitive population is the only way. There is no innocent for anyone who breath in and consume oxygen - a vital resource and then breath out carbon dioxide - a pollutant. No Innocent for any living human beginning from new born babies. There is no alternative to eliminations, because even if these competitors were let to flee planet earth, they will be occupying and ruining and squandering resources on some other planets which may be our own future escape destinations. So THE ONLY WAY IS TO ELIMINATE & TERMINATE LIVES. The dead won't flee to Mars nor any other planet to shit up the other parts of the universe.

    Therefore from now on, not grab land nor sea nor lakes nor rivers nor satellite orbit position nor oceans, nor space - JUST SIMPLY CULL & KILL HUMANS - all are legitimate targets no innocences considered, Eliminate or Be Eliminated! Survival & Future only for the fittest and strongest, EQUALITY is rubbish, the only basis of security is the LACK OF OTHERS. Resources are best secured for yourself when there are no other living competitive consumers. If there are competitive consumer it is your duty and instinct to eliminate them ASAP. More so when level of resources is low and resource is precious.

    When all the oxygen generating forest on earth died each person you can eliminate saves 11,000 liters of air (388 cubic feet) daily. It does not matter weather you grab land or not any more. You have to stop other lungs from breathing so that you can still breath yourself. Or you can kindly take suicide for other to live a bit longer - up to you!



    https://health.howstuffworks.com/human-body/systems/respiratory/question98.htm



    How much oxygen does a person consume in a day?




    The average adult at rest inhales and exhales something like 7 or 8 liters (about one-fourth of a cubic foot) of air per minute. That totals something like 11,000 liters of air (388 cubic feet) in a day.

    The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day.

    Keep Reading Below


    A person who is exercising obviously uses a lot more oxygen than that. You could determine how much air is moving through your lungs by exhaling into a plastic bag of known volume at each breath and seeing how long it takes to fill the bag.

    Remember, do not be naive to expect Science to save us, 15,000 scientists from 184 countries, repeatedly warned us by issuing signed statements of Doomsday warnings. So far ALL Religious and Political Leaders only ACT deaf and play dumb - pretending no warning had been received. On the other hand there is no any scientist oppose these warnings or offered any assurance, nor proposed any solutions.

    Each average adult human takes 11,000 liters of air - please multiply by 8 billion global population level. Please add the consumption by their pets, farm animals etc!

    Consumption of air by car engine is their engine capacity multiplied by their revolution per min speed - (divided by 2 for 4-stroke engine) this gives the amount of air intake.

    This question came from our site for active researchers, academics and students of physics.



    A reasonable first approximation would be the mass of air that the engine flies through in a minute - i.e. frontal area of the fan blades $\times$ aircraft velocity $\times$ air density. As a sanity check on your estimate, though at different conditions where the inlet velocity is not equal to the aircraft speed, at takeoff each engine on a B747 generates about 200kN of thrust, with an air mass flow of about 1 tonne (1000kg) per second. – alephzero Jan 10 at 23:34

    The CFM56-5C, the largest CFM56, powers A340. Its thrust is about 145 kN at takeoff. It has an air mass flow of 485 kg/s (source).

    [​IMG]
    CFM56-5C, source.

    The Trent XWB (A350 XWB), a larger engine developing 430 kN at takeoff, has an air mass flow of 1,440 kg/s (source).

    T/O vs cruise power and fuel consumption

    According to this document, the CFM56-5C T/O thrust is 150 kN and the cruise thrust is 40 kN (other sources states 30 kN), 27% of the T/O thrust. Related fuel consumption are 2.3 and 0.5 kg/s, meaning cruise fuel consumption is 22% of the T/O fuel consumption.

    Air mass vs fuel mass

    For a fuel consumption of 22% of the T/O consumption, it can be assumed relatively safely that the air flow is in proportion, so we can roughly estimate air mass flow in cruise to be about 485 * 0.22 = 107 kg/s. This is supported by figures found online in non authoritative sources, like page 245 of this book:

    New 100,000-hp Marine Diesel Engine - 12/10/2008
    [​IMG] [​IMG]
    Send to a Friend Printer Friendly
    The world’s biggest engine is the Wartsila-Sulzer RTA96-C. It is a turbo charged two stroke diesel engine, and it is the most powerful and efficient low revolution engine in the world today. The Wartsila-Sulser is manufactured by the Aioi Works in Japan and is part of Japan’s Diesel United Ltd engine manufacturers. It is 89 feet long, 44 feet wide, and weighs 2000 tons.

    [​IMG]
    This 12-cylinder diesel engine develops 100,000-hp at 102 rpm,
    but its “best cruise” is at 90 rpm where it burns only 1,666 gallons per hour.


    After a long absence from these pages our trusty reader, Bill Noble, has hauled his 42-footer for the winter and is finally back in Florida digging through the Internet looking for “must see” pictures and material for BoatTEST’s readers. As always, we pay Noble in 6-packs of Coors Light for his submissions and you, the readers, tell us how many he should be paid – on a scale from 1 to 4 packs. Please look over the material and register your payment suggestion below.

    These large engines are designed to power the world's super oil tankers and large container ships. They are built to the ship owners preferences. They usually request an engine construction of a single unit and single propeller design for ease of maintenance, and not surprisingly any later troubleshooting. A single unit and single screw design has also proved over time to have a longer life span than double or even quad screws.


    [​IMG]

    These engines are built in 6, 8, 10, 12 and 14 cylinder configurations. All the engines are straight or 'inline'. The diameter of each cylinder is 3 foot 2 inches with a stroke of 8 foot 2 inches. The 12 cylinder version weighs in at 2000 metric tons and delivers 90,000 horsepower at 100 revolutions per minute, with best fuel economy at 53,244 hp at 90 rpm. When I mention economy, the 14 cylinder engine for example with a displacement of 25,480 Liters ( 1.56 million cubic inches ) burns up 1,660 gallons of crude ("bunker") oil every hour.


    The Mathematical calculation: 1,660 gallons/per hour = 39.5 barrels of crude oil/used per hour = $2,844. These figures are worked out from the basis of crude oil @ $72 a barrel*. $2,844 every hour the engine runs or 27.6 Gallons which is $46.00 every minute or 76 cents a second! That is of course if the ships buy oil at trade price -- if not then these figures are the absolute minimum. ( * at time of publishing )

    When you eliminated human consumers, you will eliminate enormous amount of squandering of resources and pollution generated. It is the CLEANEST elimination. All other methods and Recycling are not truthful and very misleading. You cut 50% of global population you will cut 50% of consumption of resources - preventing them from being turned into wastes and pollutions by man, you cut 90% of this you will also cut 90% of that, you can cut 99.99% for this and that or further, we are then quite assured of AVERTING OUR OWN TOTAL EXTINCTION as warned by Scientists, and need not to try to flee to other planets as desired by Stephen Hawking.
