dimensional, high-speed movies have been made at the Wright-Patterson Air Force Base showing the action of such things as rapid-firing weapons on aircraft, flying missiles, and missile impact tests. Time-lapse movies have been made, depicting in three dimensions the life cycle of living things, and shortening them to a few seconds on the screen. Skin in Three Dimensions (General Electric Nezvs Digest, Sept.-Oct., 1951).--A new defense production tool, capable of producing jet aircraft “skin” structures lighter yet stronger than ever before possible, has been developed by engineers of the Giddings and Lewis Company, General Electric, It is thought to be the world’s and the Lockheed Aircraft Corporation. first machine for the manufacture of self-reinforced aircraft skin. The giant, 80-ft.-long machine, electronically controlled by G.E. equipment, automatically cuts, edges, and shapes a particular pattern in three dimensions in one surface of a metal sheet. A two-dimensional electronic tracer control, developed by G.E., causes the machining equipment to cut a pattern laterally and longitudinally according to a master pattern, while a cutting device known as a vertical milling head cuts the surface to varying thicknesses. The new type of skin structure will eliminate the necessity of welding or riveting into the plane the customary forest of struts, braces, and girders. Instead, fewer and simpler strengthening units will be used as integral parts of the skins, allowing new planes to be stronger, lighter and faster. The machine will be used in Lockheed’s new $S,OOO,OOOHall of Giants fabricating plant in Burbank, California, in the production of new F-94 jet fighters.
The lub-oil goes round and round in AF engines, and some of it is the same old oil, re-refined in Air Force efforts to conserve natural resources. During fiscal-51, over l,SOO,OOOgallons of used engine oil were recovered and processed, yielding 1,115,OOO gallons of re-refined oil as well as a substantial financial savings. AF estimates that for every 1000 gallons of new oil issued, 250 gallons of used oil will be accumulated, 177 gallons of re-fined oil will be recovered; plans now include re-refining of used oil from ground equipment. Thermos boots for the Marines in Korea have been tested at 45 degrees below zero, should eliminate the frostbite which claimed so many victims in the wet-cold of last winter. Actual tests of the sealed insulation rubber boots, with water frozen in the boots and wearers donning frozen socks, showed that ice melted in 8 minutes and feet stayed warm thereafter. So long as a man moves once an hour to keep circulation normal, Marines say the new boots will prevent trench foot.
A new greaseless pack for rifles has been standardized by the Army Ordnance Corps, will soon replace the heavy, greasy preservative coatings long remembered by anyone who has had to unpack and clean a new rifle. The new pack consists of an outer layer of cotton scrim, a layer of plasticcoated aluminum foil, and an inner layer of kraft paper coated with a volatile chemical compound known as VCI or volatile corrosion inhibitor. Weapons are heat-sealed in the pack, VCI vapors form an invisible film which protects all metal surfaces against corrosion. Unpacking the weapon and putting it to use is expected to take not much longer than reading this paragraph.
