•'•• .: • • fLIGHT International, 11 April 1963 USA FLIGHT SYSTEMS Narco Mk 12 Surprises Within six weeks of delivering the first Mk 12 com/nav VHF radio Narco had shipped the 1,000th unit and production is now running at 30 units per day—nearly double the highest unit-per-day rate reached on any previous Narco radio. The company had also ex pected 60 per cent of their customers to order the 90-channel version, but 80 per cent have taken the 360-channel unit. Narco "debugged" the Mk 12 by subject ing the first 50 production units to intensive testing through humidity, heat and vibra tion, 500hr continuous operation, continu ous on/off cycling and packing and delivery conditions. Rapid production build-up was made possible by "completely new con cepts of product engineering, procurement procedures, testing and quality control." FAA Bright Displays The Federal Avia tion Agency has ordered from Raytheon eight more radar bright displays for the New York, Minneapolis, Atlantic and Los Angeles ATC centres. The displays convert radio video into signals of control lable persistence, which are viewed in normal lighting conditions on television screens. Trails are retained so that track and speed of an aircraft can be assessed. The total number of these displays now ordered is 68, at a cost of $ 18.5m. They are used for positive control of aircraft flying above 24,000ft, and the FAA state that safe separation of as little as five miles can be provided. Control is exercised on an area basis related to the programme for the building of new centres and the installation of new equipment. PRODUCTS AMF Cargo Systems Order AMF Over seas Corporation have announced from Geneva that three US independent cargo airlines—World Airways and Aaxico Air lines, Oakland, Cal, and Zantop Transport, Detroit, Michigan, companies largely hand ling freight for the Air Force—have awarded contracts totalling $330,000 to the Advanced Products Group of American Machine & Foundry Co for 16 air cargo handling systems. These systems comprise lightweight, high- Continued from column 3 opposite covering Vickers aeroplanes for more than 40 years. Early in his career he worked at the A&AEE Martlesham Heath on the Vickers' Viking amphibian and he was Vickers' service representative with the RAF when the Wellesley went into squa dron service in 1937. During the last war he was Vickers' resident engineer with various RAF commands using Welling tons and Warwicks; and after the war he was sent to operators introducing the Vik ing airliner into service. 503 Metallographic analy sis of aluminium forg- ings for P & W engine components in progress at Airmotive Engineer ing Corp, Dallas, Texas, as part of the company's quality-control proce dures in manufacturing pistons and other spares for R.I830 and R.2800 engines strength, aluminium-roller conveyors, pallet- restraint locks, side guide-rails, and air craft cargo-deck attachment fittings. FAA- certified, they are used to carry cargo on DC-6As of TJSAF Logistics Air Command. In addition to current contracts, AMF have also supplied Slick Airways and Flying Tiger Line and is supplying the Boeing Co with additional AMF-designed mechanized air cargo-handling systems. Boeing have ordered 11 AMF systems for their 707-320C jet freighters to be delivered to American Airlines, PanAm and World Airways. Glass-fibre Filament Winding Two recent announcements underline the attention being given in the United States to glass- fibre filament winding, especially in rela tion to missile and space developments. Aerojet-General Corporation, Azusa, Cal, have announced the acquisition of all the glass-fibre research and development facilities, personnel, patents and technical data of Houze Glass Corp, Point Marion, Pa. These facilities are to be integrated with Aerojet-General's Structural Materials Di vision at Azusa, which has for many years been concerned with filament-winding technology. The first stage of the Polaris A-3 uses a high-strength lightweight glass case made by Aerojet. Brunswick Corporation, 1700 Messier Street, Muskegon 8, Michigan, which has a reinforced plastic and filament-winding factory of 150,000 sq ft at Marion, Va, have announced big contracts for aircraft nose radomes and other components. McDon nell Aircraft Corporation have placed contracts in excess of $2m for components for F-4B, F-4C and RF-4C aircraft. Bruns wick have also received additional orders, to a value of $2£m, for rotodome units for the US Navy Grumman E-2A Hawk- eye. Other Brunswick products include plastic primary structures with integrated anten na;, which offer "high strength/weight ratios, electrical transparency and aero- dynamically clean lines." Their 100,000 sq ft plant at Muskegon is concerned primarily with aluminium honeycomb com ponents such as wing panels, bomb-bay doors, structural members for rotodomes and other lightweight structures. Boeing 727 Auxiliary Power The 90 Boeing 727s ordered by Eastern, United and Trans World Airlines are being equip ped with Garrett-AirResearch gas turbine engines driving a 40kVA alternator to supply compressed air for engine starting and cabin air-conditioning while on the ground. Garrett say that the decision of these three airlines increases the trend towards self-sufficiency and makes APUs "almost a standard requirement on all second-generation jets scheduled for pro duction in the 1963-66 period." Firm commitments for 151 AiResearch APUs have been received from 12 airlines to date, including—in addition to Eastern, United and TWA—Ansett-ANA, Braniff, BUA, Mohawk, Bonanza, Kuwait, CAA, Hawaiian and Finnair. Integral APUs are being offered with the BAC One-Eleven and the Caravelle 10A and 10B, both of which employ AiRresearch gas turbines. The company recently designed a gas turbine auxiliary power installation for the F-27. Aircraft Conduits FAA approval has been given to Skyfiex rubber-covered conduits made by Skytronics Inc, 227 Oregon St, El Segundo, Cal, for use in all types of civil aircraft. Chamfered brass ferrules, either recessed or flat, are fixed to the conduits with high temperature solder; and the jackets are made of pressure-moulded neoprene, with a chemical additive, in place of the usual paraffin, to resist ozone. Miniature Switch Package A new minia ture switch package with a threaded jacket has been announced by Metals and Con trols Inc, a division of Texas Instruments Inc, 34 Forest Street, Attleboro, Mass. Designed originally for use in pressure switches, valves and actuators, it is now being evaluated for use in inertial space platforms and submerged hydraulic actua tors. Called the Klixon AT3-1, it is available with or without potted leads and has a current rating of 3A resistive at 28V d.c, with an operating life of 15,000 cycles at full rated load and overtravel. Ambient temperature range is —65° to +275°F (-54°C to +135°C) and vibration resis tance 65g/min. Actuating force is 20oz max and weight 0.115oz. Satellite Programme Film Cenco (Central Scientific Co), a division of Cenco Instru ments Corp, have published an illustrated brocfiure describing Exploring By Satellite, a 28min 16mm educational fim, available in both black-and-white and colour, on the US Earth satellite programme. Copies of the brochure may be obtained from the Central Scientific Company's Export De partment, 6450 W. Cortland Street, Chicago 35, 111, USA.
