苏-57批量生产，关键材料可能需要从中国进口
5月16日俄罗斯空天部队宣布将采购76架苏-57战斗机，这个消息引起外界广泛关注，俄罗斯国内外媒体对俄罗斯空天部队装备苏-57战斗机数量、部署地点进行了推测和探讨。
根据这些媒体消息，俄罗斯空天部队采购76架苏-57战斗机大约需要1600亿卢布，这些费用可能只是采购费用。如果算上全部服役期限成本应该在4500-5000 亿卢布左右。至于采购总数可能达到数百架，飞机将会生产到2030年中期之后，因此整个项目成本和费用将会达到数万亿卢布，不过海外媒体普遍不太认可1600亿这个数字，有人认为这个1600亿可能是第1批13架战斗机费用，即平均每架飞机大约120亿卢布（约合1.1亿美元）。
苏-57战斗机现在还处于早期状态
前期生产的苏-57战斗机继续采用117S发动机，这种发动机属于用四代技术改进的三代发动机，所以现在苏-57战斗机还属于早期状态。原来计划采用四代发动机-产品30发动机还在测试和试飞之中，按照俄罗斯国内媒体说法，苏-57战斗机将会从2023年起换装产品30发动机。
苏-57战斗机首批4架将会交付给位于利佩茨克的第4战术训练与试飞中心，这个中心与中国空军战术试飞训练基地相当，主要用于新型作战飞机战术试飞，战术与训练大纲编写等任务。飞机装备这个中心第968试飞团，原来有消息说第968团将会装备2架苏-57战斗机，随着飞机装备规模增加，这个数字增加到4架。
这样还有72架苏-57战斗机可以组成3个作战团，按照俄罗斯国内媒体消息这3个作战团将会部署在不同作战方向，包括西部、南部和东部，第一个作战团可能会是第303师第23团，这个团在2014年在俄罗斯空天部队之中第一个接收苏-35S战斗机，第23团驻地就在俄罗斯远东共青城附近，而苏-35S和苏-57都是共青城飞机厂生产的，这样便于部队和飞机厂及时沟通，解决技术障碍和问题。
苏-57战斗机批量生产，对于碳纤维材料要求较高
从俄罗斯国内外消息来看，苏-57战斗机批量生产还存在一些问题，主要是俄罗斯现在受到西方制裁和禁运，一些材料和元器件无法进口。其中就包括复合材料，例如碳纤维，由于俄罗斯在高品质晴纶方面能力欠缺，因此难以制备高规模碳纤维。而碳纤维是第四代战斗机关键材料之一，F-22复合材料使用比较达到25%，而F-35战斗机更是达到了35%，从这里我们可以看到生产苏-57战斗机要求大量碳纤维。2015年俄罗斯曾经向中国江苏恒神股份有限公司进口HF30-30K碳纤维，从江苏恒神公开资料来看，HF30-30K大约相当于加强版T-300碳纤维。发达国家例如日本已经实现T-1000批量生产，而中国相关单位在2019年也建成百吨级T-1000碳纤维生产。因此俄罗斯不能在碳纤维取得突破，那么苏-57战斗机只能提高金属使用比例，飞机结构重量就会增加，影响飞机性能。
中国已经能够生产T-1000级别碳纤维，但是产能需要满足国内需求
因此不排除未来俄罗斯从中国引进高规格碳纤维，但是中国自己第四代战斗机歼-20也进入了大批量生产阶段，新一代导弹也采用了碳纤维壳体，这些都需要大量的碳纤维，因此国内产能满足自用之后可能也提供不了多少给俄罗斯。从这个角度来讲材料苏-57战斗机批量生产还要俄罗斯在材料领域的进展。（作者署名：小飞猪观察）

Su-57 mass production, key materials may need to be imported from China
On May 16th, the Russian Air and Space Force announced that it would purchase 76 Su-57 fighters. This news has aroused widespread concern. The Russian and foreign media have speculated and discussed the number and deployment locations of Russian Aerospace units equipped with Su-57 fighters.
According to these media reports, the Russian Air Force’s procurement of 76 Su-57 fighters will cost approximately 160 billion rubles. These costs may be only purchase costs. If you calculate the total service period cost should be around 450-500 billion rubles. As for the total number of purchases may reach hundreds, the aircraft will be produced until the middle of 2030, so the entire project cost and cost will reach trillions of rubles, but the overseas media generally do not recognize the figure of 160 billion, some people think that the 160 billion It may be the first 13 fighter jets, or an average of about 12 billion rubles per aircraft (about $110 million).
Su-57 fighter is still in its early state
The pre-production Su-57 fighters continued to use the 117S engine, which is a three-generation engine improved with four generations of technology, so the Su-57 fighter is still in its early state. Originally planned to use four generations of engines - product 30 engines are still in the test and flight test, according to Russian domestic media, the Su-57 fighter will be replaced with 30 engines from 2023.
The first four of the Su-57 fighters will be delivered to the 4th tactical training and flight test center in Lipetsk. This center is equivalent to the Chinese Air Force tactical flight test training base. It is mainly used for tactical flight test, tactical and training program for new combat aircraft. Write and other tasks. The aircraft was equipped with the center's 968 test flight. It was reported that the 968th regiment would be equipped with two Su-57 fighters. As the size of the aircraft increased, the number increased to four.
In this way, there are 72 Su-57 fighters that can form three combat groups. According to Russian domestic media, the three combat groups will be deployed in different operational directions, including the west, south and east. The first combat group may be the first. The 23rd Regiment of the 303 Division, this group first received the Su-35S fighter in the Russian Air Force in 2014. The 23rd Regiment is located near the Komsomolsk in the Russian Far East, while the Su-35S and Su-57 are both Produced by Gongqingcheng Aircraft Factory, this will facilitate the timely communication between the troops and the aircraft factory to solve technical obstacles and problems.
Mass production of Su-57 fighters, high requirements for carbon fiber materials
Judging from the news from Russia and abroad, there are still some problems in the mass production of the Su-57 fighter. The main reason is that Russia is now subject to Western sanctions and embargoes, and some materials and components cannot be imported. These include composite materials such as carbon fiber, which is difficult to produce high-grade carbon fiber due to the lack of capacity in Russia for high-quality acrylic. Carbon fiber is one of the key materials for the fourth generation of fighters. The F-22 composite is used up to 25%, and the F-35 is 35%. From here we can see that the production of the Su-57 fighter requires a lot of carbon fiber. In 2015, Russia imported HF30-30K carbon fiber to China Jiangsu Hengshen Co., Ltd. From the information of Jiangsu Hengshen, HF30-30K is equivalent to the enhanced version of T-300 carbon fiber. Developed countries such as Japan have already achieved T-1000 mass production, while Chinese related units have also built 100-ton T-1000 carbon fiber production in 2019. Therefore, Russia can not make breakthroughs in carbon fiber, then the Su-57 fighter can only increase the proportion of metal used, and the weight of the aircraft structure will increase, affecting aircraft performance.
China has been able to produce T-1000 grade carbon fiber, but its capacity needs to meet domestic demand.
Therefore, it is not ruled out that Russia will introduce high-standard carbon fiber from China in the future, but China's own fourth-generation fighter 歼-20 has also entered the stage of mass production. The new-generation missile also uses carbon fiber casing, which requires a large amount of carbon fiber, so domestic production capacity After satisfying its own use, it may not provide much to Russia. From this point of view, the mass production of the material Su-57 fighter is also due to Russia's progress in the field of materials. (Author's signature: Xiaofei pig observation)
