布莱恩·库西奥(Blaine Curcio)和让·德维尔(Jean Deville)

作为SpaceWatch.Global与轨道网关咨询之间合作伙伴关系的一部分,我们被授予发布所选文章和文本的权限。 We are pleased to present “Dongfang Hour 中国 Aerospace 新闻 Roundup 7 Dec – 13 Dec 2020”.

您好,欢迎收看东方时报中国航空航天新闻综述的另一集!在GoTaikonauts!和我们的朋友特别鸣叫 航天工业信息港,都是航天工业新闻的绝佳来源。特别地,我们建议您检查GoTaikonauts!长期的中国报道以及《太空咖啡馆》系列 航天工业信息港。事不宜迟,该新闻从2020年12月7日至13日这一周开始更新。

iSpace 在Hyperbola 2开发中取得进展

iSpace 宣布他们已经完成生产 Hyperbola-2火箭的油箱。该公司的Hyperbola-2将使用液态甲氧萘氧化物燃料,并且是中国第一个用于直径3m以上火箭的普通舱壁燃料箱。

Common bulkhead tanks theoretically allow for more stability, more compactness, and less weight, although at the cost of complexity (structural distribution, thermal insulation). Given that we expect iSpace to launch their SQX-2 liquid methalox rocket next year, we may be in the midst of a liquid methalox rocket race among private Chinese space companies.

(有关常见舱壁的更多信息: 这里 )

iSpace 也于一周前完成 a series of supersonic wind tunnel tests for the vertical landing phase, a crucial moment of the flight with complex aerodynamics and instability. The videos and images released show Schlieren photography done in a supersonic wind tunnel, testing the efficiency of the grid fins during the landing stage. The 文章 also shows CFD simulations of the air flow during this phase.

3月11日发射了2颗CAS卫星

上周,中国发射了长征11月11日火箭,这是2020年在中国进行的第三次此类火箭发射。这次发射的掩护较少,因为它与同时进行的Chang娥五号大肆宣传保持一致。

This launch of LM-11 took place at Xichang on the 9th of December, and put into orbit 2 smallsats of the GECAM mission (aka Gravitational Wave High-energy Electromagnetic Counterpart All-Sky Monitor), and initiated by the CAS Institute of High Energy Physics in Beijing.

每颗卫星的名称分别为KX-08A和KX-08B,它们将搭载多种仪器来检测宇宙中的γ/ x波突发。

这些卫星说明了中国的日益重要的作用 在太空科学和天文学中发挥作用, and follows other scientific missions such as Wukong satellite (Dark Matter Particle Explorer) launched in 2015, the Mozi quantum satellite in 2017, or the upcoming SMILE mission with ESA (solar wind-magnetospheric interaction panoramic imaging satellite).

关于C919供应商的精彩文章

战略中心&哥伦比亚特区的智囊团-国际研究(CSIS), 12月7日发表了一篇关于中国商用航空业的好文章,尤其是从工业和技术角度来看,中国商飞的表现不佳。

根据CSIS的数据,尽管中国在许多行业内将自己转变为高科技超级大国的过程令人称赞,但民航业却不属于其中。

为了证明这一点,CSIS指出了COMAC经常出现的一些问题,包括:

  • 中国商飞的不良表现
  • 这些计划经历了重大的延误
  • 工业生产率差(以年生产率为基础)
  • 认证的麻烦
  • 及其对外国供应商的依赖

总的来说,这是一篇很好的文章,在CSIS文章的顶部链接了推荐的视频。应该考虑本文的观点,但总体而言,它提供了一些出色的信息和分析。

国家广播电视总局公告

中国的NRTA 本周宣布 该国广播部门现代化的计划。这包括几个关键短语,即“智能业务”,“ UltraHD / 4K”以及“卫星互联网/融合双向服务”。

The announcement also hits on the convergence of TV and internet access, that is, most TV can be delivered via internet access. Other points of note in the announcement included a call to build a cloud platform for satellite broadcast (建设直播卫星云平台), and to develop “two-way communications” for satellite broadcast that allow for things like online shopping, smart homes, and digitization of small towns (开展直播卫星双向融合业务试验, 推进智能家庭生态、高新视频服务、“数字乡村”栏目、应用商城在直播卫星上的应用试验).

总体而言,该公告应被视为表明中国希望实现其相对古老的线性广播产业的现代化。尽管有些省份的广播电台非常成功,但最值得注意的是 湖南电视台, which at one time was 中国 ’s second-most popular TV station (behind only CCTV1)  As noted in previous episodes, historically 中国 Sat’s broadcast business has predominantly been provincial TV stations, many of which  are currently struggling financially.  For those who want a more in-depth look at Hunan TV in particular, a 今年早些时候《经济学人》的好文章.
