chengdu j-20 3D 模型

the j-20 is a single-seat, twin-engine aircraft which appears to be somewhat larger and heavier than the comparable sukhoi t-50 and lockheed martin f-22 raptor. the j-20 may have lower supercruise speed yet greater range and less agility than a lockheed martin f-22 raptor or pak fa, but might have larger bays and carry more fuel. the j-20 has a long and wide fuselage and low jet engine intakes with a forward chine, a main delta wing, forward canards, a bubble canopy, conventional round engine exhausts and canted all-moving fins. the front section of the j-20 is similarly chiseled as the f-22 raptor and the body and tail resemble those of the sukhoi t-50 prototypethe j-20's overall stealth shaping is 'without doubt considerably better' than the f-35 and pak fa, and may be eventually comparable to the f-22, but the excessive number of airfoils on the j-20 will challenge its ability to remain stealthy from all directions. as of january 2011 the engine nozzles were clearly non-stealthy; this may be due to the fact that the final 'fifth generation' engines had not been completed yet. however, one of the prototypes uses ws-10g engines with stealthy jagged-edge nozzles and tiles.
