FLIGHT Internationai, 16 January 1969 109 INDUSTRY International Products Company News Missile Bulkheads for GE A produc tion contract valued at more than $1 million has been received toy Kaman Aircraft Division of Kaman Corporation from the Re-entry Systems Organisation of the US General Electric Co. Kaman will produce missile bulkheads used with GE's Mark 12 re-entry system. The bulkhead structure will be built at Kaman's Moosup, Conn., factory, and deliveries are to begin in April 1969 and will continue through to 1974. Automatic Undercarriage System A system called Auto-Axtion, which auto matically lowers or retracts an under carriage if the pilot fails to do so, has been developed by the Bellanca Aircraft Corporation (Alexandria, Minnesota). Heart of the Auto-Axtion system is Fairchild Controls' PSF100A low pressure sensor (right) and SDhXIOO solid state relay driver Actuating the system is a compact pack age consisting of a Fairchild Controls' PSF100A low-pressure sensor coupled with a Fairchild SDR 100 solid-state relay driver. During take-off at an airspeed of 95kt, the sensor (which is set to func tion at an air pressure equivalent to 4.5in of water) switches on the SDR 100 relay, which in turn starts the d.c. drive motor retracting the undercarriage. As airspeed drops during landing to the 95kt range, the sensor again activates the relay and motor to lower the under carriage. As a fail-safe feature the pilot may override the automatic system and raise or lower his undercarriage simply by pressing a button. To warn him that he is not flying at the optimum 95kt air speed, however, a horn or a flashing light is tied in to this override. The Fairchild sensor/relay package was chosen for several reasons—e.g., low cost, shock- and vibration-resistance and simplicity of installation. Interior of the BAC One-Eleven mock-up which is air condi tioned by a Trojan unit manufactured by Temperature Ltd (see col two). At present the cabin has execu tive furnishing, as seen here Deep-space Antennas NASA has re quested industry to submit proposals for the fabrication and erection of two 210ft diameter tracking antennas, which are to be part of NASA's Deep Space Network (DSN) for installation in Spain and Australia. About 20 US companies will have until March to submit their proposals to the Jet Propulsion Laboratory at Pasadena, Calif, which operates the DSN. By the middle of next year a prime contractor will be chosen to construct the antenna systems which are expected to cost about $13 million (£5.4 million)each. Both should be operational by 1973. These two antennas, in conjunction with the existing one at Goldstone, Calif., will send commands to and re cover data from the planned 1973 un manned photographic shots, the Viking landing mission on Mars, the Pioneer missions towards Jupiter in 1972-73 and other planetary missions possible during the 1970s and beyond. Air-conditioned Mock-up A 24ft passenger cabin mock-up of the One- Eleven installed at BAC's Weybridge factory has been provided with a custom-built air-conditioned system by Temperature Ltd, of Burlington Road. London SW6. The mock-up is combined with an adjoining conference area and the whole is maintained at 68 QF. Essentially a furnishing showroom, the mock-up displays new seating ranges, upholstery fabrics, wall panel designs and carpeting. BAC asked Denver Refrigeration Ltd to evolve a suitable system in conjunction with its own engineers. The result is a system designed round a self-contained Trojan air-conditioning unit manufactured by Temperature Ltd. which changes the air completely every eight minutes. Main inlet ducts running down from the Trojan unit situated in a false roof and along either side of the cabin at floor level form part of the forced con vection system. Air is pumped in through foot-level grilles. Shorts' Management Changes Mr E. G. Collinson has been made head of management services for Short Bros at Belfast. His previous post as manager of the Skyvan Division has now been taken by Mr Denis Tayler. former chief test pilot as recorded in Flight last week. Mr Collinson replaces Mr J. S. Brooks, who moves to the Missile Division at Castlereagh to become Blowpipe pro gramme manager. Mr W. J. Galloway. head of the company's guided weapon trials unit, becames Tigercat programme manager. Computer Programmes for Industry The US Department of Defence has joined with NASA in making computer programmes available to industry, edu cational institutions, scientific and tech nical organisations, and others who may be able to use them. Under the agree ment the DoD will submit programmes to, and help support, the Computer Software Management and Information Centre (COSMIC), established in 1966 at the University of Georgia to en courage secondary use of the results of aerospace research and development. Contour Seats Ltd (Bridge Road, Farn- borough, Hants) announce that they have received, against world competition, an order for the first-class seats on all BOAC's fleet of Boeing 747s.
