...admits that early hybrids spat unburned propellants out their nozzles, but he claims that the habit has been cured by baffles that keep the propellants from escaping before they have mixed and burned. Baffles and other improvements, says Ordahl, have boosted combustion efficiency to 90% in some U.T.C. hybrids. Aerojet-General Corp. has a different kind of baffle that is said to get 95% . The Reaction Motors Division of Thiokol Chemical Corp. believes that good burning under variable conditions can best be had by injecting extra oxidizer near the rear of the combustion chamber or downstream from the baffles...
...surprising number of aerospace, electronic and other technically oriented companies are branching into shipbuilding, figuring that their scientific talent and sharp cost accounting can bail out the industry. Ingalls Shipbuilding got a technological fillip when it was acquired three years ago by Tex Thornton's Litton Industries. Aerojet-General recently bought Jacksonville's Gibbs Shipyards, and General Dynamics last January picked up Bethlehem Steel's huge yard at Quincy, Mass. Lockheed's highly efficient subsidiary in Seattle, Puget Sound Bridge & Dry Dock, has raised its payroll from 600 to 4,000 since 1960, expects that...
...rare gamble in the Government-nurtured aerospace industry. In addition to Lockheed, Thiokol Chemical Corp., maker of the Minuteman booster, has put $12 million into a Georgia plant to build solid-propellant engines up to 21 ft. 8 in, in diameter with 3,000,000 Ibs. of thrust. Aerojet-General Corp., maker of the Navy's Polaris booster, is doing the same near Miami. The United Technology Center of United Aircraft is building smaller solids at Sunnyvale, Calif. The rocketmakers are all betting high that the National Aeronautics and Space Administration will eventually be forced to call on them...
...toss its heavier load 1,000 extra miles, the A-3 packs more thrust and less deadweight. First-stage fuel, made by Aerojet General Corp., is denser, so that more can be carried in the same space. It is also more powerful, producing a hotter flame (6,300 to 6,600° F.) and more thrust. The casing that restrains its pressure (800 to 900 lbs. per sq. in.) has been lightened by making it out of filament-wound glass fiber instead of metal...
Working with the Aerojet-General Corp. of the U.S., Old Delft is aiming at an expanding military market. Plans for the night eyes are still secret, but they would be a welcome addition to Marine landing craft, the rugged little boats that would be so much more versatile if they could be equipped to see their way toward an unfamiliar enemy beach in the dark...
