According to reliable sources XAC: New Stealth Flying Leopard JH-7B has been successfully flight. New J H-7B is a twin-seat, twin tail layout of stealth, all-weather fighter-bomber. Although the original Flying Leopard "body bone" bottom, but the big thrust to meet the new engine, new Flying Leopard had to be appropriately enlarged body size adjustment. As the new engine's inlet air quantity and unit of engine thrust than the original increase of nearly 50%, plus the stealth shape design needs, the new Flying Leopard can not simply follow and enlarge the body of the original Flying Leopard. New "Spey" engine than the "turbofan WS-9" and "Laosilaisi"
Diameter larger engine, but also short. Therefore, the researchers on the original machine's aerodynamic body shape and internal structure of a drastic improvement! Its great complexity of the workload, no less from the new design of a new aircraft. Because the body is increased so that the machine oil reserves increased significantly, so the J H-7B of the combat radius of several new active duty in the military combat aircraft has a combat radius of leading.
From the outline view; China's "J H-7B" In order to improve performance and strengthen the aerodynamic shape stealth, "JH-7B" uses the world's most popular "S"-shaped inlet, and a new nano-spray suction inlet wave coating to reduce the aircraft radar cross section and positive infrared signal characteristics, and to BWB technology integration, the whole machine the new composite application area increased significantly.
"J H-7B" The way has been improved fuel refueling equipment for the interior in order to further enhance the machine's stealth. Therefore, the "J H-7B" is the first kind of use of computer-aided design modified form of the stealth fighter-bombers.
As the "J H-7B" stealth using a newly developed radar absorbing paint, making the probability of machine to detect much lower. Canopy edge, weapons and weapons-bay doors built with jagged edges, etc. The combination of lines, can effectively reduce radar reflection. Airborne Weapon type used and the plug-in containing a balanced approach, in order to further reduce the infrared signature. J H-7B extensive use of effective stealth measures, its radar cross section (RCS) will be not more than XXX square meters.
