When they showed then it is already not their latest top secrets, outdated declassified models already. They are confident that nobody can catch up with their development.

厦大发布的载荷图片
[环球军事快评 梳理天下大事]这一回,厦大把美媒“吓大”了!最近一则消息引发航空航天领域爱好者和部分军迷的关注:4月23日,由厦门大学和凌空天行科技公司联合研制的“嘉庚一号”火箭在我国西北部沙漠无人区成功发射。而面对“带有翅膀的火箭”、“双乘波前体”等关键词,一些西方媒体似乎又紧张了,比如美国大众机械网站随后称,那似乎是一种高超音速验证飞行器,“甚至可能是一种武器系统的原型”。
嘉庚一号局部
实际上,对于中国高科技领域的动态,西方媒体总是那么敏感,还经常喜欢费时劳神地给中国装备找“爹”,在他们眼里,中国的研发成就总是“剽窃来的”,要不就是通过“逆向工程”搞来的,总之,中国科技就是不能有原创,你们中国人怎么可能凭自己的本事搞得出来呢?
近年来,面对铁一般的事实和成就,西方媒体偶尔也只能承认,某些领域中国确实走在了前面,于是,他们脆弱的心脏就更加虚得不行,东方大国的科技领域稍有一点风吹草动,他们就会一惊一乍地浮想联翩,哪怕是初步的试验,他们也会先拿过来炒作一通、把自己吓唬吓唬。而其实很多类似试验,他们自己早就搞了很多年,很多类似器械,他们自己早就搞了很多款,但他们就是见不得中国搞。
只许州官放火,不许百姓点灯!这是什么混账逻辑?
这真的是病,必须得治。那什么时候能完全治愈呢?中国科技全面领先的那一天!
厦大的这枚火箭无论从科技的角度如何评价,无论与高超音速飞行器有多大关联,这都是我们中国自己的事!退一万步,就算它是“一种武器系统的原型”,那又怎么样?我们把自己的事情干好就是,管他的西方媒体如何聒噪!
那么,具体来说,这次“嘉庚一号”火箭到底是什么?我们根据媒体报道和公开资料,略加梳理。
首先,从外形来看,这枚火箭的不同之处在于装了“翅膀”,据科技日报等媒体报道,起飞阶段由火箭发动机推动升空,达到2万米稠密大气层之外的临近空间后,转为平飞状态。此刻,载荷与箭体应该已经分离,至于载荷的动力是不是冲压发动机、还是组合动力?报道中都没有提及,我们也不便瞎猜,反正媒体继续说,平飞状态之后,“继续加速到5马赫”(5倍音速,约合6125公里/小时),“利用机翼在稀薄大气层里获得足够升力保持稳定飞行”。
至于有的专家认为,从结构图看,它并没有外媒所说的“进气口”,自然不可能采用吸气发动机。这一点,我们不能完全苟同:“结构图”看不到进气口,仅凭这一点,就能断定实物也没有进气口?当然,到底有没有进气口,以实物为准,媒体的报道没有给出现成答案。
嘉庚一号的双乘波前体
媒体还提及,“项目的最终目标是提升民航飞机速度到现有速度的五倍以上,实现两小时内的全球直达”。我们认为,这里的关键词是“两小时内的全球直达”。到这里,相信很多资深军迷会联想到另外一个短语——“一小时打遍全球”,是的,那是美国的,具体说是美军的“创意”,他们不仅这样想,也是这样做的。至于这次媒体提及的“提升民航飞机速度”,这……你懂得。我们只想说,中国C919大飞机还刚刚处于试飞阶段呢。
X-37B
美国“一小时打遍全球”宏大计划的代表性作品就是X-37B,军迷将其列为“空天战斗机”一类,起码也是未来太空战斗机的雏形,由波音公司研发,无人驾驶,可重复使用,由火箭发射进入太空,既能在地球卫星轨道上飞行、又能进入大气层,总之,厉害的狠。鉴于美国一贯的霸道行径,爱好和平的人怎能不高度警惕?
第二,继续看科技类媒体的公开报道,“嘉庚一号”火箭长8.7米,翼展2.5米,起飞质量3.7吨,最大飞行高度2.6-2.7万米,在临近空间(2万-10万米)范围内,火箭头部的试验载荷有两个,一是XTER “高超声速双乘波前体”,它由厦门大学航空航天学院研制,此前已经过了理论设计、数值分析和地面试验阶段,现在将它放到火箭上运送到指定高度和速度,在真实的飞行条件下开展“空气动力学测试”;二是舱内无线通信系统和临近空间高能粒子探测系统,它们由西安电子科技大学空间技术学院研制。
至于,有的人质疑,厦门大学能搞处那么牛的高科技吗?
在此,我们只想摆几个此前的事实:中国第一枚自行研制并成功发射的探空火箭是1958年9月8日由北京工业学院(现名:北京理工)研制发射的;2004-2017年,哈工大的小卫星七次闪耀太空,包括“快舟一号”;2018年6月2日,由武汉大学委托长光卫星研制的珞珈一号升空,用于试验验证低轨夜光遥感、导航信号增强等技术……大学,那可是有“大家”的地方。
查阅资料显示,“嘉庚一号”如果不算头部的载荷,底部的火箭名字其实是“天行Ⅰ”系列中的“天行Ⅰ-1”,作为可重复使用的高超声速运载器,天行Ⅰ可满足目前国内对高超声速总体、气动力\热、控制、材料等多学科的真实飞行试验环境获取或设计结果验证需求,为我国高超声速研究领域提供商业化、可靠、低成本的飞行试验解决方案。
那么,第三点来了——这个“天行Ⅰ”系列火箭是什么来头?
公开资料显示,“凌空天行”(北京凌空天行科技有限责任公司),成立于2018年8月,致力于解决商业航天领域中发射高成本的问题,为客户提供高可靠、低成本、便捷的航天运输服务。今年3月7日完成数千万的天使轮融资,主要用于“天行Ⅰ”项目。
凌空天行作为成立不足一年的商业航天公司,不仅快速推出“天行”可重复使用火箭产品,还通过垂直起飞、水平降落回收,在国内首次实现了全箭的整体回收重复使用。他们为何迅速取得这么亮眼的业绩?
我们查阅的资料显示,该公司的创始团队“均具有航天系统内10年以上工作经验,工作经历覆盖市场开拓、总体设计、总装生产、质量管理等航天型号研制全部关键环节”,公司核心研发团队“均在航天系统内共同工作多年,专业齐全、配合默契”。原来都是系统内的资深老手呀。
据介绍,该公司的各型产品分别对应“航空航天领域科学试验、商业小卫星组网发射、载人太空旅游等不同阶段的商业需求”。“天行I”将实现100-1000千克载荷,最大马赫数8,200公里以上的高速飞行环境,应用于新型高速发动机试验、材料测试、制导\控制测试、新设备验证等领域,在产品研发阶段就已获得一系列商业订单。
第四点,不得不再次说一说的临近空间和临近空间飞行器。
临近空间是指距地面20-100公里的空域,由于其重要的开发应用价值而在国际上关注很广。关于它的重要意义,通常的说法是这样的“随着现代高新技术的快速发展,信息对抗空间不再局限于陆地、海洋、低空,临近空间已成为现代战争的一个新战场,是国家安全体系的一个重要环节。
嘉庚一号飞行轨迹
临近空间飞行器具有航空、航天飞行器所不具有的优势,在通信保障、情报收集、电子压制、预警等方面极具巨大发展潜力,具有快速响应、超强突防、灵活机动的特点,是一种兼备战略威慑和实战应用能力的新概念武器,对于慑止强敌、控制危机和打赢战争具有重要作用,是美俄等军事大国竞相发展的利器。它可作为连接空天战场的有效纽带,在未来空天一体联合作战中扮演至关重要的角色。比如,若将其扩展成为对抗干扰平台,可以实施压制干扰和欺骗干扰,形成强大的电子对抗优势;若将其作为武器平台,则可以在大覆盖区域对目标实施随时随地的打击;它能随时应急升空,快速高效部署,飞行条件稳定,信息传输延时很小,雷达和红外特征又都很不明显,难以探测并锁定,当前的各类作战飞机和地对空导弹都难以对它构成威胁。
近20多年来,世界航空航天大国纷纷以高超声速天地往返系统、高超声速导弹和高超声速飞机为目标,形成了一股研发热潮,成为了各国抢占空中和空间战略优势的利器。
对此,崛起中的东方大国当然不会束手旁观!
因此,无论“嘉庚一号”/“天行Ⅰ-1”火箭的具体成就达到了什么水平,我们的态度简单明晰:别管西方媒体的聒噪,撇开“有色眼镜”的质疑,继续光明正大地在中国科技全面崛起的道路上努力奋进!
中国人有中国人的魄力,中国人有中国人的节奏!

The load picture released by Xiamen University, the load picture released by Xiamen University
[Global military quick review to sort out the world's big events] This time, Xiamen University "frightened" the US media! A recent news triggered the attention of aerospace enthusiasts and some military enthusiasts: On April 23, the "Jia Geng No. 1" rocket jointly developed by Xiamen University and Lingkong Tianxing Technology Co., Ltd. succeeded in the desert no man's land in northwestern China. emission. In the face of keywords such as "rocket with wings" and "double-wave precursors", some Western media seem to be nervous. For example, the US Volkswagen Machinery website later said that it seems to be a hypersonic verification aircraft. May be the prototype of a weapon system."
Jiageng No.1 Partial Jiageng No.1
In fact, the Western media is always so sensitive to the dynamics of China's high-tech sector. They often like to spend time and effort to find “爹” for Chinese equipment. In their eyes, China's R&D achievements are always “plagiarized”. It’s not through “reverse engineering”. In short, Chinese technology can’t be original. How can you Chinese people come up with their own skills?
In recent years, in the face of iron-clad facts and achievements, the Western media can only admit occasionally that in some areas China is indeed ahead of the curve, so their fragile heart is even more illusory, and the technology of the eastern powers is slightly more. When the wind blows, they will be surprised to imagine, even if it is a preliminary test, they will first take a fuss and scare themselves. In fact, many similar experiments, they have been engaged in many years, many similar devices, they have long been engaged in a lot of money, but they just can not see China.
oppressive rule! What is this git logic?
This is really a disease and must be cured. When can it be completely cured? The day when China’s technology is leading the way!
No matter how much the rocket of Xiamen University is evaluated from the perspective of technology, no matter how much it relates to the hypersonic vehicle, this is our own thing! Retreat 10,000 steps, even if it is "a prototype of a weapon system", then what? What we do to do our own thing is to control how his Western media is noisy!
So, specifically, what exactly is this "Jia Geng No. 1" rocket? We sorted out according to media reports and public information.
First of all, from the appearance point of view, the difference between this rocket is that it has "wings". According to media reports such as the Science and Technology Daily, the take-off phase is promoted by the rocket engine and reaches the adjacent space outside the dense atmosphere of 20,000 meters. Turned to a level of flying. At this point, the load and the arrow should have been separated. Is the power of the load ramjet or combined power? There is no mention in the report, we can not guess, anyway, the media continues to say, after the level of flying, "continue to accelerate to 5 Mach" (5 times the speed of sound, about 6125 km / h), "Using the wing in a thin atmosphere Get enough lift to keep a steady flight."
As for some experts, from the structural diagram, it does not have the "air intake" mentioned by foreign media, and it is naturally impossible to use an intake engine. At this point, we can't completely agree with each other: "Structural map" can't see the air inlet. With this alone, we can conclude that there is no air inlet in the real thing. Of course, in the end there is no air intake, which is subject to the real thing, the media reports did not give an answer.
The double-passing wave precursor of Jiageng No. 1
The media also mentioned that “the ultimate goal of the project is to increase the speed of civil aviation aircraft to more than five times the current speed and achieve global direct access within two hours”. We believe that the key word here is "global direct access within two hours." Here, I believe that many senior military fans will think of another phrase - "One hour to travel around the world", yes, it is the United States, specifically the "creative" of the US military, they not only think so, but also do so. . As for the "improvement of civil aircraft speed" mentioned by the media, this... you know. We just want to say that the Chinese C919 big plane is just in the test flight stage.
X-37BX-37B
The representative work of the US "One Hour to the World" grand plan is the X-37B. Military fans have classified it as an "air-space fighter". At least it is the prototype of the future space fighter. It was developed by Boeing and is unmanned. It can be reused and launched into space by rockets. It can fly in the orbit of the Earth's satellites and enter the atmosphere. In short, it is extremely powerful. Given the consistent dominance of the United States, how can peace-loving people be highly vigilant?
Second, continue to watch the public reports of the technology media. The "Jia Geng No. 1" rocket is 8.7 meters long, with a wingspan of 2.5 meters, a take-off mass of 3.7 tons, and a maximum flying height of 2.6-2.7 million meters. In the adjacent space (20,000 - 10 Within the range of 10,000 meters, there are two test loads on the rocket head. One is the XTER “hypersyonic double-passing wave precursor”, which was developed by the School of Aeronautics and Astronautics of Xiamen University. It has already passed theoretical design, numerical analysis and ground test. In the stage, it is now transported to the rocket to the specified altitude and speed, and the “aerodynamic test” is carried out under real flight conditions. Second, the in-cabin wireless communication system and the adjacent space high-energy particle detection system are used by Xi’an Electronic Technology. Development of the College of Space Technology.
As for some people, do you doubt that Xiamen University can do a good job of high technology? As for some people, do you doubt that Xiamen University can do a good job of high technology?
Here, we only want to put forward a few previous facts: China's first self-developed and successfully launched sounding rocket was launched on September 8, 1958 by Beijing Institute of Technology (now: Beijing Institute of Technology); 2004- In 2017, Harbin Institute of Technology's small satellites shined in space seven times, including “Fast Boat One”; on June 2, 2018, the No. 1 airlift developed by Wuhan University commissioned Changguang Satellite was used to test and verify the low-rail luminous Remote sensing, navigation signal enhancement and other technologies... University, that is where there is “everyone”.
According to the information, if the "Jia Geng No. 1" is not the load of the head, the name of the rocket at the bottom is actually the "Tian Xing I-1" in the "Tian Xing I" series, as a reusable hypersonic vehicle. Tianxing I can meet the requirements of real flight test environment acquisition or design result verification for hypersonic overall, aerodynamics/heat, control, materials and other multi-disciplines, providing commercialization, reliability and low cost for China's hypersonic research field. Flight test solution.
So, the third point is coming - what is this "Tianxing I" series rocket?
According to public information, “Lingkong Tianxing” (Beijing Lingkong Tianxing Technology Co., Ltd.) was established in August 2018 to solve the problem of high cost of launch in the commercial aerospace field, providing customers with high reliability, low cost and convenience. Space transportation services. On March 7 this year, tens of millions of angel rounds of financing were completed, mainly for the "Tianxing I" project.
As a commercial aerospace company that was established less than a year ago, volley Tianxing not only quickly launched the “Tianxing” reusable rocket product, but also realized the overall recycling and reuse of the whole arrow in China through vertical take-off and horizontal landing recovery. Why do they quickly achieve such brilliant results?
The data we reviewed showed that the founding team of the company “has more than 10 years of working experience in the aerospace system, and its work experience covers all key aspects of market development, overall design, final assembly production, quality management and other aerospace model development”. The company's core R&D team "Everyone has worked together for many years in the aerospace system, with complete professionalism and tacit cooperation." It turned out to be a veteran of the system.
According to reports, the company's various types of products correspond to "aerospace science experiments, commercial small satellite network launch, manned space travel and other commercial needs at different stages." "Tianxing I" will achieve a high-speed flight environment with a load of 100-1000 kg and a maximum Mach number of more than 8,200 km. It is used in new high-speed engine test, material testing, guidance, control testing, new equipment verification, etc. A series of commercial orders have been obtained at the stage.
Fourth, I have to talk about the adjacent space and the adjacent spacecraft again.
The adjacent space refers to the airspace 20-100 kilometers away from the ground. Due to its important development and application value, it has a wide international interest. Regarding its significance, the usual saying is that "With the rapid development of modern high-tech, information confrontation space is no longer limited to land, sea, and low altitude. The adjacent space has become a new battlefield for modern warfare and a national security system. An important part of it.
Jiageng No. 1 flight path Jiageng No. 1 flight track
The spacecraft has the advantages that aviation and spacecraft do not have. It has great development potential in communication security, intelligence collection, electronic suppression, early warning, etc. It has the characteristics of quick response, super penetration, and flexible maneuverability. The new concept weapon with both strategic deterrence and practical application capability plays an important role in stopping the enemy, controlling the crisis and winning the war. It is a weapon for the development of the US, Russia and other military powers. It can be used as an effective link to connect the air and space battlefield, and plays a vital role in the future joint operations of air and space. For example, if it is expanded into an anti-interference platform, it can implement suppression interference and deception interference to form a strong electronic countermeasure advantage; if it is used as a weapon platform, it can strike the target anytime and anywhere in a large coverage area; it can be used at any time. Emergency lift, rapid and efficient deployment, stable flight conditions, small information transmission delay, radar and infrared features are not obvious, difficult to detect and lock, the current various types of combat aircraft and surface-to-air missiles are difficult to construct Threat.
In the past 20 years, the world's aerospace powers have targeted the hypersonic world to the system, hypersonic missiles and hypersonic aircraft, forming a research and development boom, which has become a weapon for countries to seize the strategic advantages of air and space.
In this regard, the rise of the great powers of the East certainly will not stand by!
Therefore, no matter what level of the specific achievements of the "Jia Geng No.1" / "Tianxing I-1" rocket, our attitude is simple and clear: regardless of the noise of the Western media, open the question of "colored glasses" and continue to be bright and bright. Strive for the advancement of China's science and technology in an all-round way!
The Chinese have the power of the Chinese, and the Chinese have the rhythm of the Chinese!
