TECHNICAL: D EFENCE Rockwell studies IR Rockwell International's Tac tical Systems division has been awarded a $1.3 million contract by the Naval Research Laboratory to develop a proto type mid-wave infra-red threat- warning sensor. During the 15-month pro gramme Rockwell will design, test and deliver the two-colour, staring-array infra-red sensor prototype. The unit will be used in flight tests to demonstrate that threats can be detected reliably, and at sufficient range, to protect US military aircraft, ships and armoured vehicles. The system includes a focal- plane array, multiplexer, filter, cooling dewar, optics and elec tronics. The focal-plane array, identified as the most critical component of the sensor, will be a large, 128 x 128-detector staring array. The design uses a Rockwell proprietary process and is composed of mercury cadmium telluride on a sap phire substrate, operating in the 3-5 micron band width. Rockwell's Tactical Systems division has also won a $360,000 US Army contract to design, build and deliver an operational long-wave infra-red imaging system based on a star ing focal-plane-array sensor. The system will provide infra red imagery in standard mono chrome or colour video format, and data suitable for computer processing. When interfaced with the sensor sub-assembly, the system will extract the image from the 128 x 128 focal-plane-array and correct the image for non- uniformity. The system can be expanded to a 256 x 256 array. The lens size is representative of Hellfire-sized missile seekers. • On the upgrade: GR.5 Harriers aim for GR.7 standards BAe begins GR.5 upgrade A £16 million contract has been awarded to British Aerospace by the UK Ministry of Defence to begin upgrading- 58 Royal Air Force Harrier II GR.5s to GR.7 standard, which will allow the aircraft to carry out low-level night attacks. The modifications include the fitting of a forward-looking infra-red sensor, a digital elec tronic moving-map display to assist low-level navigation, and revised cockpit lighting which allows the pilot to wear night- vision goggles. The RAF has ordered a total of 110 Harrier lis of all types: 62 Harrier GR.5s (already built), 34 new-build GR.7s (de: livery in progress) and 14 two- seat Harrier T. 10s (on order). • FIT IS OUR CONCERN A large profit is designed spe cifically into CN-235 for regional transport. It is a multipurpose light transport aircraft, specially for short or medium haul routes, able to take off from and land on short or unprepared airfields. Its interior cabin is able to accommodate 44 seats of passengers and can be quickly converted from one con figuration to another for cargo or combi-transport, photographic survey, navigation training, even for military missions. The CN-235 minimises turn around-time. Ramp door position and access doors facilitate more for both passengers and luggage traffic as well as other services such as refuelling and cleaning. It has the lowest purchase- price in its class, along with low maintenance cost and efficient fuel consumption. Fitted with the twin General Electric CT7-9C turboprop engines with 1750 Shp each, the CN-235 can attain higher speeds. The N-250 improves your profit. It is designed to meet the ever-growing demands of regional airlines that need to transfer passengers, from international routes to domestic links. To fulfill this need, the N-250 has been designed as an ad vanced turboprop aircraft in which passengers will have the same feeling of security and comfort comparable to levels of jet-class quality. Attractive features of the N-250 are the multi-hop capability, minimum turn-around-time, excellent take-off and landing performance, low maintenance cost, efficient fuel consumption and it achieves a trouble-free operating concept. The N-250, with its generous, higher and wider aisles, will com fortably accommodate 50 to 54 passengers and baggage. Modern air conditioning and pressurization systems add to performance advantage. Noise levels are even lower which is an added plus to the environment. The CN-235 and N-250 are the aircraft to meet the tough de mands of the feeder-liners for increasing your profits. PT.
