Chinese 6-generation Fighter (CAC J-36)

This is one of the three jets which gain attentions from the world in recent days. The jet is produced by Chengdu Airplane Cooperation (CAC), with three engines and a diamond wing.
On December 26, 2024, videos of the new diamond-like plane went virus on the internet. The plane took off at CAC's airport, accompanied by a J-20S. Days before the flight, clues had appeared on the internet, indicating a new triple-engine, twin-pilot fighter was going to appear. From the photos we learnt that the plane is numbered "36011" on the nose. Given that the first J-20 is numbered "2001", it is reasonable to guess that this is the first craft of "J-36" projects.
The main purposes of the plane is not clear. Some say the plane is designed to take air superiority, but the aerodynamic design is unlikely to attain high maneuverability. Some say this is actually a boomer, and it has a range of more than 6,000km. Besides, speculation arises for the three-engine design. Some infer that the middle engine is a brand-new engine designed for high altitude and high speed (over Mach 3), while some argue that it is unlikely for the plane to achieve that speed.
This work is still rough due to lack of further information. Although the plane probably has two crew members, I still use the single seat cockpit since photos of the cockpit are not clear. I also use three identical engines, and only 3 out of 5 control surfaces on the wing are deployed. Besides, I add movable wing tips (use Slider 1 to control) and cheating gyros to attain maneuverability. I am impressed by CAC's designers that they achieve fly control without my cheating components.
