B-2飞机的结构特点B-2飞机的机翼主要由一根钛合金翼梁和一个在中央段/内翼段贯通的钛合金盒式结构构成。该结构为简单的承力结构件。外翼段为独立的复合材料组件,长19.8米。整体加强蒙皮厚23毫米。左右机翼内形成若干整体油箱,总燃油容量达74844千克。机体后段部分长15.2米,也由复合材料制成。机翼前缘内部是锲形隔板,内填蜂窝状雷达吸波材料,能使电磁波能量在反复折射中消耗掉。整个机翼前缘复盖绝缘材料,发动机舱四周采用耐高温复合材料以使发动机能够埋藏在机翼的中翼段内。这些材料能承受232℃的高温。进气道呈S形,以
Structural Features of the B-2 Aircraft The wings of the B-2 aircraft are mainly composed of a titanium alloy spar and a titanium alloy box structure penetrating the central section / inner section. The structure is a simple bearing structure. Outer wing segment is an independent composite component, 19.8 meters long. The overall thickness of 23 mm thick skin. Around the wing to form a number of the overall tank, the total fuel capacity of 74844 kg. The rear part of the body is 15.2 meters long and is made of composite material. Wings inside the front edge of the wing-shaped partition, filled with cellular radar absorbing material, can make the electromagnetic wave energy consumed in the repeated refraction. The entire front edge of the wing is covered with insulating material and the engine compartment is surrounded by a high temperature resistant composite material so that the engine can be buried in the middle wing section of the wing. These materials can withstand 232 ℃ high temperature. The inlet is S-shaped
