The difference is that these European fighters have pylons on the tip of the delta wing, which is not as obvious as J- 10. Secondly, 歼-10 really looks awkward and not very nice!
The front delta wing J 10 is called "canard wing", and its function is:
If the horizontal tail is moved to both sides of the nose in front of the main wing, the same control efficiency can be achieved with a smaller wing surface. The front wing and the wing can generate lift at the same time, unlike the horizontal tail, which will generate negative lift in most cases. The early duck layout flew like a duck, hence the name "duck layout".
An aircraft with canard layout has little advantage in normal flight, but when the aircraft needs high-intensity maneuvers, such as pitching up and hovering with small radius, strong vortex systems will be generated on the front wing and main wing of the aircraft, and the mutual coupling and enhancement between the two vortex systems will produce stronger lift than the conventional layout. Therefore, under the same conditions, the duck layout aircraft has better maneuverability than the traditional layout aircraft. When Sweden developed its own national air defense fighter, due to the characteristics of its own territory and its own military strength, it particularly emphasized the maneuverability and short take-off and landing performance of the aircraft. After various choices, they chose the duck layout. After World War II, JAS-35 Xiaolong, JAS-37 Thunder and JAS-39 Gryphon were all equipped with duck layout.
