    • A method of forming an airplane wing and a resulting article of manufacture where a wing structural member is provided which is composed of a plastic foam layer sandwiched between opposing paper sheets. A substantial portion of one of the paper sheets is removed from the plastic foam through application of water to pulpify one of the paper sheets and then stripping such from the plastic foam layer. The resulting structural member is then formed into a predetermined contour after compression of the foam layer in the leading edge region of the wing. Rib elements may be secured to an internal surface of the wing and the trailing edges are tapered prior to securement of the trailing wing edges throughout the wing extended length.
    • 一种形成飞机机翼的方法以及由此产生的制品,其中设置有由夹在相对的纸张之间的塑料泡沫层构成的翼结构件。 其中一个纸张的大部分通过施加水从塑料泡沫中去除,以对纸张之一进行造纸,然后从塑料泡沫层剥离。 然后将所得到的结构构件在机翼的前缘区域中的泡沫层压缩之后形成预定的轮廓。 肋元件可以固定到机翼的内表面,并且在将后翼边缘固定在机翼延伸长度之前,后缘是锥形的。
