Chengdu Aircraft Design Institute (or 611 Aircraft Design Institute, Chinese成都飞机设计研究所, Pinyin: Chéngdū fēijī shèjì yánjiūsuǒ), or «CADI», is a Chinese design institute and jointer partners with Chengdu Aircraft Industry Group for military aircraft.
The CADI seems to be working on the J-XX 5th Generation Fighter Aircraft, a stealth fighter project seemingly designated J-13 , a less radical design than the competing Shenyang J-12, yet seen by some sources as getting better chances to be selected by the PLAAF around 2015. Possibly developed from the Jiān 10 in cooperation with MiGAvia, this project may be powered by two improved Saturn AL-41F engines with thrust-vectoring nozzles, and a 20 T MTOW. The designers are hoping to surpass the Eurofighter Typhoon or the Dassault Rafale, though the F-22 Raptor's capabilities would remain out of sight. But little is known about this J-13 project, as can be seen at and other sources, and still less from the CADI's pages.
