Large transport aircraft developed by China in the 1960s

大家好！给大家介绍一款非常有趣的中国运输机！



1969年，中国提出了建造大型运输机的计划。不久之后，工程师参考洛克希德 C-141A 设计了 Y-9（1969）。



这是Y-9（1969）的数据：



最大飞行速度900～950公里/小时，巡航速度743公里/小时，起飞推力比0.30，最大爬升率27～32米/秒，实用升力极限11500～12500米，最大载重航程为7000至7500公里，起飞滑行距离为1 390至1500米，降落滑行距离为1270至1400米。



事实上，按照中国当时的技术水平和物质条件，不可能实现运9这样的大型运输机的研发。因此，1971年年中，Y-9项目的研发工作中断。运9虽然是一首不切实际的“狂想曲”，但为后来我国大中型运输机的研发提供了借鉴，也时刻警示着中国人“实事求是”精神的重要性”。



后来，“Y-9”这个名字被用于 Y-8 的衍生型号。

Hello everyone! Introduce you to a very interesting Chinese transport plane!

In 1969, China put forward a plan to build large transport aircraft. Soon after, engineers designed the Y-9 (1969) with reference to Lockheed C-141A.
This is the data of Y-9 (1969):
The maximum flying speed is 900 to 950 kilometers per hour, the cruise speed is 743 kilometers per hour, the take-off thrust ratio is 0.30, the maximum climb rate is 27 to 32 meters per second, the practical lift limit is 11,500 to 12500 meters, the maximum load range is 7,000 to 7,500 kilometers, and the take-off and slide distance is 1 It is 390 to 1500 meters, and the landing taxi distance is 1270 to 1400 meters.

In fact, according to China's technical level and material conditions at that time, it was impossible to realize the research and development of a large transport aircraft like Y-9. Therefore, in mid-1971, the research and development of the Y-9 project was interrupted. Although Y-9 is an unrealistic "rhapsody", it provided a reference for the later research and development of large and medium-sized transport aircraft in China, and also always warned of the importance of the spirit of Chinese to "seeking truth from facts".

Later, the name "Y-9" was used in a derivative of the Y-8.

I suppose this was related to China efforts to get Spey turbofans and reverse-engineer them ? At some point was also a larger derivate of the Tu-16 with better engines.
No surprise nothing happened in 1971... China's aerospace efforts were kind at rock bottom, due to political circumstances in that (very) troubled era, late Mao era was pretty nightmarish. Lin Biao died that year in still mysterious circumstances.

The Y-9 is very likely an upgrade of Tu-16（H-6）.

I'm glad to hear from you! I think so. The Y-9 is very likely an upgrade of Tu-16.
