If nothing else, it's the third all-new Chinese military aircraft to emerge in two years, a pace of innovation unknown since the Cold War. It is also by far the largest indigenously developed Chinese aircraft.

Kiinalaiset ovat jo ainakin parin vuosikymmenen ajan tehneet "reverse-engineeringiä" eli purkaneet ja yrittäneet kopioida moottoreita. Nykyteknologialla (esim. 3D-skannerit) puretun osan mitat saadaan sadasosamillimetrien tarkkuudella suoraan 3D-malliksi. Ongelma on siitä huolimatta edelleen sitkeästi olemassa. Ilmeisesti moottoriteknologiassa on kuumuudenkestoon jne. liittyviä jippoja, joiden selvittämiseksi täytyisi tuntea valmistusprosessi yksityiskohtaisesti.SJ kirjoitti:Sikäli kun olen ymmärtänyt, niin kiinalaisilla on ongelmia noiden moottorien kehittämisessä, niin onko mahdollista, että ne hankkii nuo osittain siksi, että saavat muutaman moottorin tutkittavaksi? Siis onko noissa moottoreissa mitään mitä kiinalaiset voisivat niistä oppia?

It is probably no coincidence that modules for China's planned space station will be similar in size to powerful reconnaissance satellites. Rockets designed for one can launch the other. For the same reason, a new factory at Tianjin to build 6-8 outsize spacecraft a year has a clear military role.
The plant's best-known products will be modules for the space station that China plans to build around 2020, but another product line will be “large remote-sensing satellites.” The big spacecraft from Tianjin will join smaller payloads in a launch program that envisages sending up 30 rockets annually over the next seven years, more than doubling the rate of recent years.

New Communist Party chief Xi Jinping, who is also chairman of the Central Military Commission, approved the rules which aim to promote austerity and control expenditure, the official Xinhua news agency said.
