This is the nation's first all weather axial flow turbojet engine, the General Electric J-47-GE-23, which is going into large volume production for the world's fastest bomber, the Boeing B-47 Stratojet. To meet the needs for the six-jet Air Force bomber, General Electric will produce the ""23"" at Lynn Mass, and Lockland Ohio and also has licensed the Packard Motor Car Company and the Studebaker Corporation to manufacture the engine. Providing considerably more thrust of driving force than previously announced for the J-47 engines now in production, the all-weather turbojet has a thrust rating of more than 5,800 pounds and also has a lower rate of fuel consumption than earlier models. This will provide future models of the B-47 with even greater speed and range. The engine has a ""hot nose,"" made possible by bleeding hot air from the compressor to hollow nose parts, which provide anti-icing protection. It also has a special ignition system which makes possible high altitude starts and may be equipped with water injection for thrust augmentation.

ABOVE: General Electric jet center, Lockland Ohio. Dedicated March 18-19 on the 10th anniversary of the running of America's first jet engine and the GE Lynn, Mass. Plant. Utilizing nearly 4,000,000 square feet of floor space, the center encompasses facilities for development, parts production, assembly and test of turbojet engines for the Air Force. General Electric now occupies much of the plant which was erected in WWII for airplanes piston engines manufacturing and in addition has erected new office and factory buildings. Additional development facilities are under construction. The large building in the center is owned and occupied by the electric auto-light company. The building to the right if it has been leased by the GE from General Auto-light. The three structures on the far right are Air Force owned and occupied by GE. The tract at left is owned by GE and included the new factory and office buildings and development facilities. BELOW: seven aircraft jet engines, all developed by the GE Company's Aircraft Gas Turbine Division for the U.S. Air Force, graphically show evolution in size and design from the first engine built in this county, the General Electric I-A to the elongated J47-GE-17 and J-73, the company's latest turbojet. Not shown is the axial flow J-35 turbojet, for which engineering and manufacturing responsibilities were turned over to the Allison Division of General Motor Corp. several years ago.""

Although most of the engineers at the General Electric Company's Aircraft Gas Turbine Division laboratories do not consider themselves detectives, they spend most of their time ""just getting the facts."" To aid them in their search for clues to a better jet engines is this new Vacuum Fusion Gas Analyzer which is used to determine the exact amount of oxygen, hydrogen, and nitrogen in various metals and alloys. The gas content of a metal affects its strength. This is particularly true of titanium, the new ""light weight champion"" alloy so called because of its lower density and high strength. The metal under test is first heated in a small furnace to temperatures as high as 2400 degrees Centigrade to release the gases. The gases, caught in the glass tubing, circulate to a collection bulb where the engineer is able to determine the smallest residues of gas and is able to separate each gas for further analysis. The apparatus can determine if there are 10 parts of gas per million with an accuracy of plus of minus 10 per cent of the amount present.
