【J-20A has adopted flexible skin, the flap seams have disappeared, fifth-generation fighters can now create a generation gap】
The 9.3 military parade, the PLA officially announced the latest model of J-20, J-20A. On-site footage shows that J-20A has not only a protrusion behind the cockpit, but also the flap structure has changed from the previous split structure to an integrated structure covered with flexible skin.
We all know that stealth fighters try to eliminate seam structures as much as possible during design, the purpose is to prevent these seams from damaging the stealth performance of the airframe.
But some structures are constrained by technical level and cannot be solved, so they can only reduce the impact through technical means.
The leading edge flaps of the J-20 have this problem. But in the J-20A, thanks to the application of flexible skin technology, we can now solve the gap between the leading edge flaps and the wings.
It is worth noting that for fifth-generation fighters, even a slight improvement in stealth performance can significantly enhance the combat effectiveness of stealth fighters.
Therefore, in a way, when fifth-generation fighters and fourth-generation fighters create a generation gap based on the presence or absence of stealth performance, the quality of stealth performance of fifth-generation fighters will also create a certain generation gap among themselves.
J-20A is already ahead of J-20, and in the future, the advantage against F-35 and even older F-22 will be even greater.
