隐身飞机与非隐身飞机有很大的差别。在垂直面,特别是垂直安定面和机身侧壁的面积应尽可能缩小。这就使飞机具有一种极为平滑的外形轮廓。还应当避免机翼形状的不连续(比如导致电导率的不连续),这就使翼型曲线特别突出。此外,飞机的蒙皮要经过特殊的精加工,不能有结点,而且要用能吸收和散射雷达波能量的材料制造。当然,这种飞机不能有外挂部件,比如机载武器或辅助燃油箱;发动机 Stealth aircraft and non-stealth aircraft are very different. In the vertical plane, especially the vertical stabilizer and the side wall area should be as small as possible. This gives the aircraft an extremely smooth profile. A discontinuity in the shape of the wing (such as a discontinuity in conductivity) should also be avoided, which makes the airfoil curve particularly prominent. In addition, the skin of the aircraft has to be specially finished, not knotted, and made of materials that absorb and scatter the energy of the radar wave. Of course, this aircraft can not have plug-in components, such as airborne weapons or auxiliary fuel tank; engine
