114 FLIGHT International, 16 January (944 INDUSTRY International. . . alloy used in Titan. He continues: "We were able to convert these fixtures for welding work on the Titan III even though the tank thicknesses will be increased 50 per cent and more. But we very deliberately retained the same inside tank diameter, and allowed our increased thickness to move the outside skin line." Gauge thickness of the tanks must be increased because of addi- tional weight and thrust. The Titan III-C version will include a pair of solid-propellant motors, each rated at more than 1,000,0001b thrust (this journal, August 1 last). United Technology Center will build the solid motors, which will be attached to support forgings built into the core vehicle. These forgings—extensions of existing motor mounts—will be standard for all vehicles, even those that will be flown with- out the solids. With an entirely new upper "Transtage," the core vehicle will be used as the booster for a variety of space projects. Transtage, which will be capable of multi- restarts in space, will generate 16,0001b thrust. Its tanks will be constructed of titanium. "The weight savings we will make using titanium are extremely important," Mr Healey says, "since all weight reduction in Transtage can be translated directly to pay- load. It is harder to work with, however, and requires special handling to avoid scratches and contamination at weld joints." Fuel and oxidizer tanks in Transtage will be milled down from a 0.5in forging to a thick- ness of 0.0625in. Although it is a new stage —and tooling is being developed to solve new machining and welding problems— some Titan I fixtures are being adapted for Transtage production. Equipment for Fill Simulation Acontract worth $lm has gone to General Precision's Link Division, of Binghampton, NY, from General Dynamics, for equipment to be used in the development of the F-lll variable-sweep tactical fighter for the USAF and USN. The equipment to be supplied includes a Mk 1 digital simulation computer, a motion system, instrumentation, control- loading equipment and a visual target display which will be integrated with General Dynamics' own cockpit and tactics simulation equipment in DORA—a Dyna- mic Operator Response Apparatus. This will test and verify the interior design and operation of the two-seat F-lll cockpit, leading to the most effective arrangement of controls, instruments and tactical equipment. Link's Mk 1 digital simulation computer is already in use in airline 707 flight simu- lators and will soon be used in USAF C-135 and C-141A simulators and Gemini manned satellite simulators for NASA. Record Lycoming Contract The largest- ever single production order received by Avco's Lycoming Division, of Stratford, Conn, was placed recently for T53-L-11 1,100 h.p. gas turbine engines for the US Army's UH-1 Iroquois helicopter. The contract is worth $41,631,605. Another Army contract received at about the same time is for another version of the engine, the T53-L-7, also rated at 1,100 h.p., for OV-1 Mohawk reconnaissance aircraft. Value of this contract is $4,935,636. Contracts for Hiller and Bell Both Hiller Aircraft and the Bell Helicopter Co were awarded big follow-on contracts last month to continue production of three-seat, piston- engined light observation helicopters for the US Army: presumably the Army's last purchase of aircraft of this class before selection is made of its future turbine- powered observation machine, a potentially vast contract for which Hiller, Bell and Hughes are competing. Hiller's new contract, worth §6,029,100 is for 210 OH-23G Ravens, and follows one worth over $4.3m awarded early last year. It will continue OH-23G production into the autumn of next year. Bell will build a further 115 OH-13S helicopters under their $3,731,750 contract, after the expiry of a $4,655,934 contract for 150 awarded in January last year. The OH-13S is a military version of the civil Bell 47G-3B. More Space for Piasecki The Piasecki Aircraft Corp has leased two buildings at Philadelphia International Airport which increase its plant there by 51 per cent. Ground leased will enable a threefold future expansion to be made. Expansion plans have also been made for the 70,000 sq ft factory which the company operates at Mayfield, Pa. Leach International Appointment Mr Bayard Fox has been appointed vice- president and general manager, Europe, of Leach International SA, the Geneva-based European subsidiary of the Leach Corpor- ation electronics firm, of San Marino, Calif. Leach International have manufac- turing facilities at Geneva and Munich. LI European Operations Mr Garry G. Gould has been appointed manager of European operations for the Litton Indus- tries Inc Data Systems Division, Canoga Park, Calif. With headquarters at Schwa- mendingenstrasse 5, Zurich, Switzerland, Mr Gould will be responsible, in his newly created post, "for European market- ing of command and control systems developed and manufactured by the division and other business activities affecting the company's sales growth in Europe." Latin America Foothold in El Salvador The Central Bank of El Salvador recently announced that a company to assemble spare parts for jet aircraft, and to undertake jet aircraft overhauls, was being set up at Ilopango. It was hoped it would be in operation this month. The company, Sociedad de Jet Avion International de El Salvador, is understood to be associated with Jet Avion Corp, of Miami, Fla. Capital of the new company, raised locally, from the USA and from neighbouring Central American coun- tries, is 3£m Colones (about £500,000), the Central Bank statement said. A US MATS C-133 Cargomaster takes on fuel from a 41,500 gal Goodyear Pillow tank. Four of these huge tanks, plus pumps and plumbing provided by Bowser Inc, constitute an air-transportable refuelling facility being used by USAF units throughout the world, particu- larly on undeveloped airstrips. Many units utilize two systems simultanecusly—one for JP-4 and one for Avgas USSR New Polymers Developed A heat-resis- tant polymer—polynitryl—possessing the properties of a semiconductor has been obtained from nitryl. It can withstand momentary heating to l,000°C. A group of Moscow University chemists, working under the direction of Academician Valentin Kargin, developed theoretically a method of nitryl polymerization that differs radically from the conventional technique. It is this that made possible the polymerization of nitryl which chemists thought could not be polymerized. Employing the new method, Moscow chemists have also obtained a polymer of acetone. They are now planning to extend considerably the range of substances from which entirely new polymers with unusual properties can be obtained.
