some recent rumors:
1. The Commercial Space Department of the State Administration of Science, Technology and Industry for National Defense (SASTIND) has been established. Currently, launches in preparation need to go through a centralized re-approval process and will be collectively postponed (including almost all rockets except those that have already launched dozens of times). Although the establishment of the Commercial Space Department has caused delays shortly, it is evident that commercial space activities will begin to scale up next year, making this a necessary step. The most important role is to clarify standards and eliminate bureaucratic buck-passing.
2. Some issues have arisen with the progress of Wenchang LC301.
3. The CZ-10B is intended to fill the gap before the rocket using the YF150 is developed.
4. Build 7-meter-class rockets first.
5. The High-Pressure Test Stand for Rocket Engines in the U.S. is too expensive (costing $7 billion at the time), so it will not be built in China. China does not have such a super facility like the U.S., which generally means domestic engines cannot keep up with SpaceX, but this does not mean domestic engines are inferior.
6. The CZ12 is being developed quickly and cheaply, and in terms of price, only the ZQ2E can compete with it.
7. The Full-flow staged combustion (FFSC) will not be seen on a rocket next year.
8. The actual FY100 engine and the recently mentioned model diagram are very different, with even the turbine location being different.
9. The most capable domestic private engine design company is Space Pioneer. Space Pioneer's FFSC has already completed its design drawings.
1.国防科工局商业航天司成立,目前准备中的发射需要重新走集中审批流程,要集体推迟(包括几乎所有火箭除了打了几十发的)。商业航天司的出现虽然导致了推迟,但肉眼可见的明年商业航天会开始上量,所以这个是必要的。最重要的作用是明确标准,不再踢皮球
2.文昌LC301进度出了些问题
3.十乙是用来填用yf150的火箭出来前的空白的
4.先造7米级火箭
5.美国的那个火箭发动机挤压试车台造价太高(当年的70亿美元)所以不建。国内没有美国的那个超级挤压台,发动机一般赶不spaceX,但不是说国内的发动机差。
6.cz12搓得又快又便宜,价格上只有zq2e能与之一战
7.全流量发动机明年见不到上箭
8.fy100实机和模型图差得很远,涡轮位置都不一样
9.国内民营发动机设计能力最厉害的是天兵。天兵全流量发动机已经出图纸了。
