13 JUNE 1952 FLIGHT 3 PROCESS FOR NICKEL COATING OF ALUMINUM TO PROLONG PROPELLER BLADE LIFE —Development of a process for nickel coating of aluminum, hitherto considered impossible, was an nounced jointly last March by the Hamilton Standard Division of United Aircraft Corporation, and the Bart Laboratories Company of Belleville, New Jersey, The plating process, which was developed for the U.S. Air Force and the U.S. Navy, is of major importance to Hamilton Standard because it protects propeller blades from pitting and erosion by spray thrown up in sea landings and take-offs. Solid duraluminum propeller blades equipped with the new coating are already in service on Martin P5M-1 flying boats and Grumman UF-1 utility amphibians. Several hundred landings and take-offs with the two airplane types have conclusively demonstrated the coating's protective qualities. Tests at Hamilton Standard showed unplated blades lost approximately 20 per cent of their tip area while coated blades were relatively unharmed. U.S. ARMY TAKES DELIVERY OF ITS FIRST H-19 CARGO HELICOPTERS —The first Sikorsky H-19 cargo helicopter was delivered to the United States Army in January, 1952. It is one of approximately 100 of the big 10-place craft which the Army has ordered from Sikorsky Aircraft for delivery during 1952. Adoption of Sikorsky H-19s is a big step forward for the Army transport system. They will be used to speed the supply of ammunition, food, medical items and related goods to front line troops. In addition, they will transport troops to otherwise in accessible areas. The craft will be operated by the newly-created helicopter trans port companies of the Army Transportation Corps, FORD MOTOR COMPANY LICENSED TO BUILD P&W J-57 TURBO-WASP —The Pratt & Whitney Air craft Division of United Aircraft Corporation has licensed the Ford Motor Company to build its big, axial-flow J-57. The engines will be built under a production planning contract awarded to Ford by the U.S. Air Force. The J-57 has been chosen for the new Boeing B-52 eight-jet bomber, and is also to be installed on the Con- vair YB-60, and on high speed military fighters still under security restrictions. EUROPE'S TOOLS HELP PRATT & WHITNEY MEET SHORTAGE —Already at work on vital pro duction jobs at Pratt & Whitney Aircraft are the first of some 74 new machine tools which the company has purchased from European manufacturers during the past year. These foreign purchases represent a total investment of over $1,700,000, and were made because Europe's machinery manufacturers could guarantee earlier delivery than manufacturers of comparable American machines. Most of the tools which Pratt & Whitney has purchased abroad are the large, complex types which take many months to build. These include radial drills, horizontal and vertical milling machines, facing lathes, and boring mills. These orders placed abroad represent only a very small portion of the new tooling which the Pratt & Whitney Aircraft Division has ordered since the beginning of Amer ica's military expansion program.
