    Since no one mentioned this, the last photo is photoshopped. The bow has been flattened and the island reduced in size. It appears someone wanted to see what the Liaoning would look like if it was a catapult carrier.

    Finally a close up showing the serials

    370, 372 and 373

    Missing is 371 but we know it’s already exists

    4 x Z9D for SAR on CV-16

    I am so surprised that no one had said anything about this article: https://mil.sina.cn/sd/2019-05-15/detail-ihvhiews2077975.d.html?from=singlemessage&isappinstalled=0

    辽宁舰每百公里耗油54吨 一次加满8000吨要花1600万
    辽宁号航空母舰是我国第一艘航母,该航母由原来俄制瓦良格号改装而成,其主要动力系统是4具TB-12蒸汽轮机,配合8台增压锅炉,使用4轴推进模式,最大输出功率为20万马力,和使用西屋A4W压水反应堆的美军10万吨尼米兹级核动力航母相差仅为6万马力。辽宁舰采用重油锅炉的蒸汽轮机动力,辽宁舰好和俄海军“库兹涅佐夫”号航母采用同样的动力配置,动力系统为8台增压锅炉+四台蒸汽轮机的组合,使用重油做为燃料。

    相对于人们熟知的汽油、柴油和煤油,可能很多人并没有听说过重油,重油也叫燃料油,广泛的应用于船舶、发电站和供热领域。重油也是石油的重要产物。众所周知,石油原油的提炼过程其实就是一个蒸馏过程,主要依靠不同的温度分离提炼出不同的燃料。提炼完汽油、煤油、柴油后,接下来就是重油了,提炼完重油后,剩下的部分还可以提炼出沥青等物质。重油就是石油提炼出汽油、煤油、柴油后的主要残留物。它的性质比较特殊,和汽油、煤油、柴油这些液体燃料不同。重油的粘稠度非常高,比较容易凝固,所以重油在被使用前还需要进行加热,降低它的粘稠度,才能进行管道输送和后续使用。这也是采用蒸汽轮机动力的舰船出航准备时间长达数小时的重要原因,而使用燃气轮式的舰船出航准备时间则短得多。
    目前不仅仅是辽宁舰和“库兹涅佐夫”号航母使用重油,很多大型船舶都是使用重油。按照设计,使用蒸汽轮机的常规航母上的锅炉可以使用任何燃料,例如汽油、煤油、柴油等都可以,但最终还是选择了重油,主要是重油拥有一些比较独特的优点。重油的密度较高,容易储存,而且热值相对很高,更加适合供大功率机器使用。最为重要的一个原因,就是重油价格低廉,非常便宜。目前国内的舰用重油的价格大约为2100元/吨,这明显低于汽油、煤油、柴油等燃料的价格,例如船用轻质柴油的价格大约为7100元/吨,是重油价格的三倍以上。


    根据公开的报道,辽宁舰在2015年的一次航海活动,共计38天,共使用了高达8000吨燃油。从航速来看,辽宁舰跑得和尼米兹级航母是差不多的,之前辽宁舰也曾经持续保持30节的高航速航行了5个小时,证实了这艘航母的高强度航行能力。辽宁舰的满载排水量达到6万多吨,一次可搭载8000吨的舰艇燃料,这些燃料可供它以18节~20节的平均速度航行大约8000海里,采用30节高速巡航可行驶3800海里。这样算来,大约每海里油耗1吨。一海里是1.85公里,那么这相当于百公里油耗54吨。

    常规动力航母的耗费是相当高的,单就一艘航母的日常消耗就可以将一个中小级别的国家拖垮。如果使用的是重油,那么辽宁舰进行一次燃料补给大约需要1680万人民币。换成是柴油的话,那么费用将达到5680万人民币,一艘航母服役时间长达数十年,期间需要进行无数次燃料补给,由此积累下来的燃料成本差距将会非常巨大,自然是不容忽视的,这就是辽宁舰为什么要使用重油的原因。值得一提的是,未来中国新航母的发展方向肯定是向核动力迈进。(作者署名:科罗廖夫)


    The article says that Liaoning consumes 54 metric tons of fuel for every 100 km or one ton per NM. Liaoning outputs 200,000 horsepower, only 60000 less than American Nimitz class carriers. In 2015, Liaoning had a 38 days mission, consuming 8000 tons fuel. If the speed at 18-20 NM per hour, Liaoning can travel approximately 8000 NM. If the speed is 30 NM per hour, she can go 3800 NM. Liaoning has been traveling at constant speed of 30 NM per hour for 5 sustained hours.

    So at 18-20 knots it’s 1 ton per NM

    At 30 knots it’s ~2 ton per NM

    Basically doubling the consumption at 30 knots

    These are expected and normal conditions.

    To be confirmed but it seems that the Liaoning aircraft carrier is in Bohai Bay now until June 1st. Operational recovery or Certification of the 10th promotion of the air carrier pilots? CCTV-7 reported Wednesday night training for J-15 pilots.
