The US and Japan experts believe that North Korea’s missile technology has steadily improved, but still not fully grasp the data map: North Korea’s rocket launching site. (picture from the network) Reference News Network reported on February 12th   the foreign media reports, the commander of the U.S. Army space and missile defense command said on the 10, although the satellite launch North Korea recently didn’t seem to be able to ground transmission signal, but the rocket payload reached two times the DPRK launched last time, really worry. According to the Reuters reported on February 10th, David · a man in the Capitol Hill conference organization in the United States on the Hudson said: "look at the last launch and payload into orbit at that time, I think only the weight increase is a key factor." He said: "I don’t think the satellite can transmit the signal successfully, but it does reflect the ability of North Korea to try to strengthen the missile technology."." This payload was almost two times as much as the North Korean satellite launched in 2012, Mann said. He didn’t give the exact figure of the payload, but South Korean officials thought it was 200 kilograms. According to Japan’s "Yomiuri Shimbun" reported on the 2 11 7, North Korea launched the long-range ballistic missile, will be equipped with firing to orbit. Although North Korea’s reality is shrouded in a veil, scientists have found that Korean technology is very high-end after analyzing data and pictures. "Korea’s technological strength has steadily improved." After reading the DPRK missile launch screen, Japan’s former Defense Department of the Ministry of Technology Research Institute of the third Institute of long-term protection Tatsunami Nosuke made the above judgment. The orbit of the launch object is close to the special orbit of the earth observation satellite, so it is necessary to fine tune the direction of the flight when the object is put into the orbit. "It can be said that North Korea has mastered the more difficult part of flight control technology," said Akiba Jiro, an honorary professor of the Institute of space science, who has been working on rocket development for many years." The time of the one or two missile falling before it was reduced by 3 to 6 minutes compared with the last time, and the time of firing to the same height can be shortened. "It means that North Korea has been able to burn a lot of fuel in a short time," said Sawaoka Aki, President of the University of Datong, who is familiar with the theory of cosmic engineering. The propulsive force should be about 20% higher than the previous one." Reported, but North Korea will carry things into orbit around the earth, did not let it fall. Therefore, it can be concluded that North Korea has not yet mastered the long-range ballistic missile technology. One of the reasons is that it is very difficult to get the missile back into the atmosphere from space again. Re entering the atmosphere needs to withstand 1000 degrees of high temperature, so the need for high-end heat resistant technology. 美日专家认为朝鲜导弹技术稳步提高但仍未完全掌握 资料图: 朝鲜的火箭发射场。(图片源于网络)   参考消息网2月12日报道 外媒称,美国陆军空间和导弹防御司令部司令10日表示,虽然朝鲜近日发射的那颗卫星似乎没能向地面传输信号,但运载火箭的有效载荷达到了朝鲜上次发射的两倍,着实令人担忧。   据路透社2月10日报道,戴维·曼中将在美国哈得孙研究所组织的一场国会山研讨会上说:“看看上次的发射以及当时送入轨道的有效载荷,我觉得仅仅重量上的增幅就是一个关键要素。”   他说:“我认为卫星没能成功传输信号,但它确实反映了朝鲜在导弹技术方面试图加强的一种能力。”   曼表示,这次的有效载荷几乎是2012年朝鲜发射卫星时的两倍。他没有给出这次有效载荷的具体数字,但有韩国官员认为是200公斤。   另据日本《读卖新闻》2月11日报道,朝鲜7日发射了事实上的远程弹道导弹,将搭载物发射至绕地轨道。尽管朝鲜的实际情况笼罩着一层面纱,但科学家们在分析数据和画面后发现,朝鲜的技术已经非常高端。   “朝鲜的技术实力稳步提高。”在看完朝鲜公布的导弹发射画面后,日本前防卫厅技术研究本部第三研究所所长久保田浪之介作出了上述判断。   朝鲜所发射物体的轨道接近适合地球观测卫星等的特殊轨道,将物体投入该轨道,需要对途中飞行方向进行微调。多年来从事火箭开发的宇宙科学研究所名誉教授秋叶镣二郎表示:“可以说朝鲜掌握了飞行控制技术中比较难的部分。”   一、二级导弹下落前的用时比上次减少了3到6分钟,可以认为发射至相同高度的燃烧时间有所缩短。熟悉宇宙工程学的大同大学校长泽冈昭分析说:“这意味着朝鲜已经能够在短时间内燃烧掉大量燃料。推进力应该比上一次提升了20%左右。”   报道称,但朝鲜将搭载物送入绕地轨道,未让其下落。因此可以认为,朝鲜尚未完全掌握远程弹道导弹技术。其理由之一是,让导弹从宇宙空间再次进入大气层的技术非常难。再次进入大气层需要经受住1000度以上的高温,所以需要高端的耐热技术。相关的主题文章:
