主题：【原创】F-22的蒙皮怎么皱起来了？ -- 晨枫

那个it 指代的是座舱盖，不是蒙批

The plane's million-dollar radar-absorbing canopy has also caused problems, with a stuck hatch imprisoning a pilot for hours in 2006 and engineers unable to extend the canopy's lifespan beyond about 18 months of flying time.

从生产图上看， 那个锯齿花纹的部分是设备检查舱口盖，黄色的锯齿，

横向条装花纹应该是整块的复合材料，黑色的 这个横向条纹

估计是机体frame(肋骨） 跟蒙皮结合的部分，
