AIDC F-CK-1 Ching-kuo Projects & Derivatives

J101 was designated in the turbojet number sequence (J79, J97 etc). It was a USAF designation.

J101/SF was a scaled down F404 giving about 12,000lb thrust. It is possible the bypass ratio was reduced, as the PW1120 did from the F100, leading it to revert to the J101 designation.

According to the article, originally it was just a scaled fan version of the F404, hence the SF, but that ended up being 500 lbs too heavy. It states they then scaled the whole engine to make this one, but it has 80% parts commonality with the F404.

What would be estimated performance of Ching Kuo with 12,000 Lb. thrust engines?

Wouldn't putting an F404 in the F-CK-1 require a whole new fuselage (i.e. a new plane)?

I realize that I am responding to a 2018 post, but sometimes you just have to - lol. In response to the above, it would require a new fuselage/plane, and it is called a F-18a, or YF-17.
 
Adding some old materials from General Hua Xijun, the core leader of the IDF project. He was once one of the most elite U-2 pilots and later took full charge of Taiwan's aviation industry. In his memoir published in 1999, he described different design phases. The earliest XF-6 design looked very similar to Israel's Kfir, which is understandable given Taiwan's special relationship with Israel at the time. Subsequent designs underwent many changes, including conventional layouts and tailless configurations

Interesting.
The first pic, the canard delta, has a wing sweep of 60 degrees, which is precisely the same as the Mirage III, and a near identical wingspan, within 4 inches of that jet.
Any other info on this design in the book?

The book provides only a brief introduction to the XF-6 . The plan began in 1978, with its core function being interception, designed to counter the MiG-21. The maximum speed requirement was over Mach 2, with a target of reaching Mach 2.3. The engine was based on the J79, and there was even a proposal to equip it with three J85 engines. The project was later named the "Ying Yang(Soaring Eagle) Project." However, the Taiwan Air Force soon realized that its design capabilities were insufficient to meet the requirements and began seeking assistance from the US, This eventually evolved into the IDF project. Interestingly, The Mirage2000 currently in Taiwan serves a role very similar to the original XF-6 concept, also focusing on high-speed interception.
 
I rememeber (from a south african publication I think) there was an effort between Israel, Taiwan and South Africa to develop a common fighter.
Maybe the XF-6 concept is connected to that.
