福建舰的实力

为什么福建舰没有选择核动力？是技术问题还是什么问题？

据统计，航母的动力由来可以分成核动力和常规动力两类。现阶段全世界服役航母中选用核动力的仅有美国“尼米兹”级、“福特”级及其法国的“戴高乐”号。别的世界各国航母均为常规动力。

通常来讲，核动力航母的优点主要是“几近无尽的续航能力”，还能够省下舰用燃料的室内空间，从而带上大量航母舰载机然料和武器装备贮备。美国“福特”级核动力航母在计划的50年干龄内无需拆换燃料，可完成核反应堆和航母共同使用寿命。除此之外，核反应堆工作中时不用气体，可以节约人的全面发展的排烟道室内空间，让舰岛构造更小并有利于提高红外线隐藏实际效果。

但常规动力航母与核动力航母在战斗效率层面并没有太大区别。美国“中途岛”级基本航母在夫妻冷战期内多次参与部分矛盾，“小鹰”级基本航母还一直参军到21世际初，他们配备的航母舰载机军队和同时期的核动力航母相差无异。

而核动力航母的缺陷和优势一样突出。军事专家表明，核动力航母存在工程造价价格昂贵、修建周期时间较长、检修难度系数高、临战损伤填补比较艰难等缺陷。例如“福特”级选用的两部压水核反应堆工程造价就达到数十亿美元。航母应用的核反应堆研发技术水平大，对大小和抗冲击工作能力的规定十分高，并且还要专门的专业技术人员。除此之外，核航母的拆卸花费也比基本航母高得多。总而言之，从全使用寿命周期时间花费看，服役周期时间在50年以上的核动力航母花销远远高于常规动力航母。

可以说，核反应堆自身的高新技术门槛就阻拦了它的营销推广，而核动力航母的优点现阶段也并不显著。由于核动力航母有着无尽续航能力，不意味着航母战斗群也具有同样的工作能力，为航母保驾护航的巡逻舰、航母和驱逐舰等全是常规动力，必须经常补充。就算是美国航母打压群也需要借助全世界海军基地和随行地快速补给舰给予服务保障。因而核动力航母是不是合适于其他国家，还值得商榷。

但假如目光放得更远些，从行业发展趋势看，核动力航母的发展前景更强。据了解，伴随着现代化工艺的发展趋势，电磁轨道炮、功率大的定向能武器和全电推进系统软件等现代化工艺对电力的需求量愈来愈高。现阶段美国“福特”级航母和英国“伊丽莎白女王”级航母已选用了综合性电力工程推动系统软件，其动力装置最先推动功率大的发电机发电，随后借助计算机把电磁能精准地划分给动力装置、雷达探测系统软件和战斗部等差异的用电量单位。

这类行为可以将全舰的电力工程综合性分派：必须快速飞行时，就将电磁能优先选择提供给推动系统软件；必须战斗时，就将电磁能转至武器装备上。将来航母很有可能武器装备的激光武器、电磁轨道炮、电磁弹射等都属于短期内必须很多电磁能供货的武器装备，对电磁能分派规定很高，常规动力系统软件的总输出功率无法再次提高，且没法长期性满输出功率运行，不可以达到较大的电力工程要求，而核反应堆输出功率大、不断运行时间长的优点就十分明显了。

The strength of Fujian warship why did Fujian warship not choose nuclear power? Is it a technical problem or something? According to statistics, the power source of aircraft carriers can be divided into nuclear power and conventional power. At present, the only aircraft carriers in service in the world that use nuclear power are the American Nimitz class, Ford class and the French Charles de Gaulle. Other aircraft carriers in the world are conventional power. Generally speaking, the advantages of nuclear powered aircraft carriers are "nearly endless endurance capability", which can also save the indoor space of ship fuel, so as to bring a large number of aircraft fuel and weapons and equipment reserves. The U.S. "Ford" class nuclear powered aircraft carrier does not need to replace fuel within the planned 50 year dry age, and can complete the same service life of the nuclear reactor and aircraft carrier. In addition, no gas is used in the operation of the nuclear reactor, which can save the indoor space of the exhaust flue for people's all-round development, make the structure of the ship Island smaller, and help to improve the actual effect of infrared concealment. However, there is not much difference between conventional powered aircraft carrier and nuclear powered aircraft carrier in terms of combat efficiency. The "Midway Island" class basic aircraft carrier of the United States participated in some contradictions for many times during the cold war period between the husband and wife. The "little Eagle" class basic aircraft carrier still joined the army until the beginning of the 21st century. The aircraft carrier based aircraft army they were equipped with was no different from the nuclear powered aircraft carrier of the same period. The defects of nuclear powered aircraft carriers are as prominent as their advantages. Military experts have shown that the nuclear powered aircraft carrier has some defects, such as high engineering cost, long construction cycle, high maintenance difficulty coefficient, and difficult to fill the battle damage. For example, the cost of the two pressurized water nuclear reactors selected for the Ford class has reached billions of dollars. The research and development technology level of nuclear reactors used in aircraft carriers is high, and the regulations on size and impact resistance are very high, and special professional technicians are also required. In addition, the dismantlement cost of nuclear aircraft carriers is much higher than that of basic aircraft carriers. In a word, from the perspective of full life cycle time, the cost of nuclear powered aircraft carriers with an active service cycle of more than 50 years is much higher than that of conventional powered aircraft carriers. It can be said that the high-tech barrier of the nuclear reactor itself has hindered its marketing promotion, and the advantages of the nuclear powered aircraft carrier are not significant at this stage. Because nuclear powered aircraft carriers have endless endurance capability, it does not mean that aircraft carrier battle groups also have the same working capability. Patrol ships, aircraft carriers and destroyers escorting aircraft carriers are all conventional power and must be supplemented frequently. Even US aircraft carriers need to rely on naval bases all over the world and accompanying fast supply ships to provide service support. Therefore, whether the nuclear powered aircraft carrier is suitable for other countries is worth discussing. But if we look further, from the perspective of industry development trend, the development prospect of nuclear powered aircraft carrier is stronger. It is understood that, along with the development trend of modern technology, modern technology such as electromagnetic railguns, high-power directional energy weapons and all electric propulsion system software has an increasing demand for power. At this stage, the American "Ford" class aircraft carrier and the British "Queen Elizabeth" class aircraft carrier have selected the comprehensive power engineering propulsion system software. Its power unit first drives the high-power generator to generate electricity, and then accurately divides the electromagnetic energy into different power consumption units such as power unit, radar detection system software and warhead with the help of computer. This kind of behavior can comprehensively distribute the power engineering of the whole ship: when it is necessary to fly quickly, the electromagnetic energy will be preferentially provided to the propulsion system software; When it is necessary to fight, electromagnetic energy is transferred to weapons and equipment. In the future, it is likely that the laser weapons, electromagnetic railguns, electromagnetic catapults, etc. of the aircraft carrier's weapons and equipment are all weapons and equipment that must be supplied with a lot of electromagnetic energy in the short term. The regulations on electromagnetic energy distribution are very high. The total output power of the conventional power system software cannot be increased again, and it is impossible to operate at full output power for a long time, so it can not meet the requirements of large power engineering. However, the advantages of the nuclear reactor with large output power and long continuous operation time are very obvious.
