The fighter aircraft J-10 impresses people most because of its aerodynamic look, though the metal bar located above air intake slightly disfigures its sleek shape.

The bar caused much speculation among people, some of whom believed the bar was actually a telescopic device, while some others thought it was for airframe reinforcement, and other thought it was simply a radar antenna.

Apparently, the bar couldn’t possibly be radar antenna since electronic signals would be seriously be obstructed by severe turbulence if electronic equipment were installed in the joint of air intake and airframe. Meanwhile the bar cannot be a telescopic device as there is no sign of sliding or overlapping sections. In all, as agreed by many international weaponry experts, this metal bar is most likely for structure reinforcement purposes.
