Chinese is very angry and claim MMU is very ugly.
根据土耳其媒体报道,当地时间16日,土耳其航空航天工业公司(TUSAŞ)研发的第五代战斗机TF-X,在总装厂所在的本场进行了首次内部亮相。从视频中拍摄的画面来看,TF-X已经基本完成了制造工作,正停在滑行道上加油…

Pulling out TF-X like this also gave us some more intuitive impressions of its possible technical and tactical performance. It is estimated that more than one person has two impressions after seeing this fighter: one is that the appearance of TF-X is indeed a bit "not very good-looking"; the other is that the appearance of TF-X is actually "a bit mixed" .
Not so good-looking TF-X
Saying that TF-X looks a bit ugly, let’s talk about our intuitive impression. The shape and lines of TF-X can be described as both stiff and thin:
We all know that typical fifth-generation fighter jets, such as F-22A and J-20, have a smooth aerodynamic shape, few sharp transitions on the aerodynamic surface, fusion of wing and body, and natural envelope of the engine compartment, such as the tip of the vertical tail. Sometimes there is also sharpening. This is not only an optimization for the supersonic performance of the fighter, but also a necessary requirement for the low detectable performance of the fighter.
In contrast, TF-X is obviously much worse. Let me put it bluntly. At first glance, this aircraft is not designed so naturally from the fuselage to the wings, from the wings to the vertical tail, and from the vertical tail...
For example, from the air inlet to the wing, the F-22A and the J-20 have a natural transition, basically implementing the principle of parallel aerodynamic surfaces. And this TF-X has an extra fold line inexplicably, it looks like the centerline of the fuselage and the wings are not on the same level at all, which looks extremely ugly.
Another example is the vertical tail of TF-X. Since there is no cutting edge treatment and no full-motion vertical tail design, the vertical tail of TF-X looks thinner, just like adding two large pieces of iron on the top of the fuselage. the same. At the same time, the transition between the vertical tail and the fuselage is also extremely rigid, lacking the necessary chamfer transition, and the shape-conserving design is not well done. Compared with the F-22A and J-20 as a whole, how do you say it? Looking left and right, it doesn’t look so pleasing to the eye. Generally speaking, it doesn’t feel very good.
