It is a model just for show, allegedly based on a noval or whatever science fiction story. This is what I wrote for Key-Publishing:
"In addition to the events that have perhaps been summarized far too briefly above, there was also a funny - or rather embarrassing - story: AVIC has set up a 1:1 model of a futuristic fighter of the "6th generation" a little away from the regular exhibition area. Anyone who knows a little about the Chinese scene will have immediately recognized that this is a what-if, a pure fantasy product based on a novel/novella, according to which this model, known as the “White Emperor B”.
Almost as expected, several Western agencies have eagerly pounced on it and sensationally reported that “China has taken the lead in the race to develop a sixth-generation fighter jet”, “China is revealing an advanced prototype demonstrating China’s vision for next-generation air superiority” and so on. This type would be capable of flying at high-Mach numbers in almost near-space altitudes, would combine cutting-edge weaponry, AI-supported sensors and a human-machine collaboration system in order to enhance pilot decision-making and optimize mission performance”!
In fact, it is just a what-if model."
