COMMERCIAL AIRCRAFT OF THE WORLD are the use of the JT8D-200 series, the remanufac- tured JT8D-400 and the R-R Tay 670 at around 75.6kN of thrust. _ The UAS Engineering division of United Aviation Services has a hushkit system for P&WJT3D-3Bs fitted to MDC DC-8-50751s, which it claims will offer Stage 111 noise-limit compliance for the aircraft. The company says that noise reduction is achieved with a passive system for absorbing the excess engine noise produced primarily by the fan section. Constructed of aluminium and stainless steel, the only visible difference to the modified engine is the extended nose-cone, which is strengthened to be suffer, incorporating redundant load paths to the mounting flange.

Douglas DC-8-62/63s are catered for by Burbank Aeronautical Corp II (BAC II), which gained the FAA supplemental type certificate for its ADC Upgrade Kit on 15 August, 1991. The BAC II kit, priced at $1.5 million, includes engine nacelle components allowing aircraft fitted with the Aeronautical Development Stage 2 hushkit (ADC Stage 2), to meet Stage III noise regulations. A BAC II Stage 3 hushkit is also certificated for previously unmodified DC-8-62/63 aircraft en gines and available at S2.1 million.

Aerospatiale, Alenia and Deutsche Aerospace together propose a family ol regional aircraft, including two jet transports, the Deutsche Aero- space-Alenia-Aerospatiale DAA 92 to carry 87 to 94 passengers and the DAA 122 for 117 to 127 passengers. Both versions would have a range of 2,775km with an extended-range option. Powered by new engines in the 67-89kN class from Allison, BMW R-R, CFM International or P&W/MTU all of which are working on such projects, the aircraft would have improved oper ating costs and passenger comfort, while being designed for ease of handling and maintenance by operators, leading to attractive fajres on shorter routes. »•• Airbus A320 technology will be used, including digital systems. Fly-by-wire technology allows the vise of sidestick controllers in the cockpit. Intended to replace existing 100-seat types which fail to meet airport noise regulations and are likely to be phased out, the new types would be built by a joint programme company based in Germany. The company would be owned 50% by Deutsche Aerospace and 25% each by Aero spatiale and Alenia. A joint marketing, sales and product-support organisation would be set up in France. DAA 92 tf -^--^SjsswcKrv i The consortium expects to take one-third of the 2,000-aircraft market it believes to exist for this class of regional airliner. Launch of the programme in April 1992 would lead to a maiden flight scheduled for the first quarter of 1995, followed by customer deliveries early in 1996.

In 1991, Alenia Aeronautica and the Society ol Japanese Aerospace Companies joined the group. FAST is intended to transport 250 passengers 11,000km at Mach 2.2, with 222 passengers in business class. A two-crew cockpit may include artificial vision. Variable-cycle engines with advanced combustion-chamber technology to reduce emis sion levels and new noise-absorption techniques would be used. Aerodynamic developments will include su personic laminar flow control and a variable- camber wing. Deutsche Airbus also leads a joint cryogen-fuel project, involving several other German compa nies, with Soviet manufacturers Tupolev, Kuznet- sov and the N1AT institute. Using methane or hydrogen fuel in place of kerosene, the project will use a modified Airbus A310. This follows on from Soviet research pro gramme using a Tupolev Tu-155, which has been flying since 1988 and has one engine able to burn methane, hydrogen or kerosene. The gaseous fuels are cooled to -235°C for 56 FLIGHT INTERNATIONAL 4 - 10 September, 1991
