Turbofans and turboprops by manufacturer The grounding of older JT8D-powered aircraft (left) is bad news for Pratt & Whitney, while Rolls-Royce's BR-715 (right) powers the Boeing 717-200, which is under threat CONVERSION FACTORS 1,0001b thrust = 4.45kN 1,000shp = 745kW Model Max thrust (lb) Power max (SL) (shp) Notes/Description (inc submodel) Florida-based Agilis Engines, an engineering services company established in 1993 by ex-Pratt & Whitney employees, shifted its focus this year to developing the 1,0001b- thrust TF-1000 turbofan for the Safire S-26 personal jet after upping the initial thrust target beyond the original 800lb originally. The expanded thrust range also means the TF-1000 will compete for more applications against the Williams FJ22. Core tests of the 4:1 thrust ratio lightweight engine are due to start in the second quarter of next year, with first engine-to-test due in the third quarter. First flight is scheduled for late 2003, with certification due a year later. TF-1000 1,000 Turbofan Safire S-26 •MM.MMJW1 Prospects for increased production of the PS-90A turbofan are looking better than in recent times following renewed interest by Aeroflot and Atlant Soyuz in passenger and freighter versions of the llyushin II-96-400. Derived from the defunct P&W PW2337-powered II-96M/T, Aeroflot is positioned to order four -400T freighters, and is expected to decide on potential orders for passenger versions in 2002, while Atlant has firmed up the first four orders of a 10 aircraft commitment. They would be a wel come boost for engine builder Perm which saw annual production of PS-90s drop from 37 in 1992 to three in 1998 and zero in 1999. After taking an order for a single engine in 2000, new orders for from Aeroflot for six ll-96-300s had already shown signs of a turnaround for the company which has also been making efforts to bolster PS-90A reliability. Further PS-90A opportunities are likely with the growing domestic market for the Tupolev Tu-214/234. The first two production-standard Tu-214s have now entered service with Khabarovsk-based Dal' avia under a pioneering Russian leasing scheme that could lead to further orders for another 30 aircraft. Another variant dubbed the PS-90A-76 is being developed to power the II-76. •••• PS-90-A76 31,955 PS-90-A 35,300 D-30 D-30-KU 24,247 Turbofan - llyushin II-62M, IL-76T Tupolev Tu-154M -30K, -30KPV powers Beriev A40 Turbofan - Powers llyushin II-76MF.

An Avic l-led sponsored effort is aimed at developing a 70-90 passenger regional aircraft with entry-into-service targeted for 2005. The AVIC II initiative, launched independently with Hainan Airlines and Fairchild Dornier is believed to be based around a project dubbed Golden Dragon-30. International engine makers active in the region include R-R, which signed an agreement to study possible use of the BR710 to power the proposed AVIC 1 ARJ21 regional jet. Principal civil engine makers include Zhuzhou-based China National South which produces the WJ6 and WJ9 turboprops as well as the WZ-8, a licence-built Turbomeca Arriel, and www.flightinternational.com FLIGHT INTERNATIONAL 13-19 NOVEM BER 2001 67
