Manual USN 25 Basic Problems Metal Forming Aircraft
The subject goes beyond airframe fabrication and can be used as a reference to metal fabrication of any kind.
It is an ideal reference for engineers and students with an interest in metal forming as it was in the 1940s. All of the techniques in here can be adapted to your own project. Hi tech 60 years ago is garage tech today.
This e-book is as per the original manual - a beautiful little gem. There are 42 pages with illustrations per the original. As with all of our CD publications, they are high resolution text and graphics are sharp and clear. Where fold-out pages are present, they are presented as seen and not chopped down or altered in any way.
1. Introduction. The development of the all-metal airplane has followed closely the development of aluminum and its alloys. The light weight of aluminum, together with the high tensile strength of its alloys, has made it an ideal metal not only for the structural members of the airplane, but also as a covering for all surfaces such as the wings, the fuselage, and the tail section. The formability of the metal has made it possible to shape aluminum alloy sheets and strips to any contour required for the perfect streamiling of the skin surfaces, and to use realtively thin material to form such structural shapes as Z setions, channel sections, and such others as may be needed in the construction of the plane.
