IAE INTERNATIONAL AERO ENGINES UNVEILS V2500 -- 'CLEAN BURN' COMBUSTOR

 GLASTONBURY, Conn., Aug. 9 /PRNewswire/ -- IAE International Aero Engines' "green" V2500 has completed a series of development tests that demonstrate the capabilities of the new Axially Staged "Clean Burn" Combustor. The new combustor will dramatically reduce the levels of Nitrogen Oxides emitted into the atmosphere by the V2500. The tests showed a NOx reduction of over 50 percent compared with the engine in service today and has also demonstrated the potential for additional reductions.
 The Axially Staged Combustor is a revolutionary two-stage combustor, designed and produced by Pratt & Whitney on behalf of the IAE collaboration. This new technology component uses the engine's electronic control system and two concentric rings of fuel nozzles to modulate the proportions of fuel and air in the combustor to minimize levels of NOx production at all flight conditions.
 This testing has confirmed the engine's ability to meet its "green" target and at the same time has demonstrated that there was no degradation of the V2500's proven and excellent handling characteristics during starting and rapid accelerations and decelerations of the engine. The testing has also shown that the levels of other pollutants, such as carbon monoxide, unburned hydrocarbons and smoke, are very low and remain significantly less than the legislative limit.
 The NOx production levels demonstrated in this series of tests are about two-thirds lower than the existing legislative limit for the V2500. With this level of technology incorporated in the world's current fleet of all civil airliners, about one million tons less NOx would be emitted each year compared to engines that equal the limit. The analysis of the test results shows there is potential for an additional reduction in NOx emissions on the V2500 of up to 30 percent from the demonstrated level.
 This new combustor is scheduled to enter service in 1996 when the V2500 begins operation on the McDonnell Douglas MD-90 with Scandanavian Airlines System. The new combustor is an option on all new V2500-A5/-D5s and will also be retrofittable to existing -A5s/-D5s.
 The V2500 has been ordered on the Airbus A320 and A321 and the McDonnell Douglas MD-90-30 as well as being suitable for the A319 and MD-90-50. The current V2500 order book stands at 1700 engines with a value of about $9.5 billion. IAE International Aero Engines AG is a collaborative venture between Rolls-Royce, MTU and FiatAvio in Europe, Pratt & Whitney in the United States and J.A.E.C. in Japan.
