The total requirement is estimated at up to 1,300 engines for all programmes, and the 300th production RTM322 was completed in mid-2001. The turboshaft powers 44 EH 101 Merlin HMA1 s for the Royal Navy, 22 Merlin HC3s for the Royal Air Force and is being installed in 67 Apache AH1 s for the 1.22 24 Martin C-130H Turbofan. BAE Nimrod MRA4 RTM322 RTM322 British Army. The most significant recent event for the engine was its selection in late 2001 by five new European customers - Finland, Norway, Portugal and Sweden for the twin-engined NH90; Denmark and Portugal for the EH101. These selections follow earlier agreements with Germany, France and the Netherlands for up to 399 RTM322-powered NH90s. First deliveries to Germany begin in 2004, to France in 2005 and to the Netherlands in 2007. 2,244 240 1.04 0.45 14.0 Turboshaft. AgustaWestland EH101, NH Industries NH90, Apache AH1 SAMARA KUZNETSOV The 10th NK-93 engine has been assembled by the Samara Kuznetsov Scientific and Engineering Complex (Samara Kuznetsov NTK) to support the start of evalu ation on the llyushin II-76LL flying testbed. The propfan engine is designed to power the Tupolev Tu-330 military transport and produce up to 39,500lb thrust, with potential growth to around 44,000lb, says the design bureau. Samara also intends to use the baseline core as the foundation for a new family of engines. NK-93 NK-93 Although certification of the NK-93 is due by the end of 2003, the initial Tu-330 versions are expected to be powered by the conventional PS-90 (see Aviadvigatel). Series production of the engine is expected to start around 2005, after the assembly of as many as 15 prototype engines. The core is based largely on the NK-38ST ground-based industrial gas turbine and is therefore well defined as Samara approaches the start of production, it says. 39,500 Propfan. Tupolev Tu-330 mmmmmmmmBm Key developments remain focused on the M88 turbofan as part of efforts to boost Dassault Rafale sales. A longer-life, reduced fuel burn derivative, the M88-2E4, was qualified by the French defence procurement agency in December 2001. The Rafale, powered by an M88-3 growth derivative, offering 20% more thrust, was "ranked number one following the test and evaluation programme" in the still-to- be-decided Korean F-X fighter competition, claims Snecma. More than 60 M88-2s have now been assembled, of which 34 have logged more than 5,000h in service. But Snecma's long-term ambitions for other M88 derivatives were hit when Airbus Military Company re-opened bids for its A400M military transport. The Aero Propulsion Alliance, formed to develop the TP400 around the M88 core, has been dissolved and a new team configured around a revised three-shaft core concept. Sales of Dassault's Mirage 2000 continue to provide further life for the M53, of which 617 were in service at the start of 2002. More than 930,000 flight hours have been logged by the engine, which is in service in Egypt, France, Greece, India, Peru, Qatar and the United Arab Emirates. Snecma continues to offer an "evolved" upgrade derivative, dubbed the M53-PX3, offering higher thrust, improved afterburner and new FADEC controller. The long-running Larzac is set for its 3 millionth flight hour in 2003 and continues to be active. Snecma is to deliver the first Larzac 04-H20 versions to Hindustan Aeronautics in June 2002 for installation in the HJT36 single-engined trainer. The 04-R20 version is also being installed in initial versions of the RSK MiG-AT trainer. Certification is expected in late 2002 pending the unfreezing of a $53 million credit line set up by the French government to support the development. Snecma, with its group member Turbomeca, has also teamed with Klimov to boost Larzac thrust to 3,830lb.

The 3,750lb-thrust engine is being developed for the "Russianised" version of the MiG-AT in place of the Larzac engine, while a more powerful derivative, the 5,500lb-thrust RD-2500, is being developed for the compet ing Yakovlev Yak-130. For testing of the Yak, the RD-2500 will be paired with a PSLM-produced DV-2. Funding for the RD-1700, estimated at $85 million for 16 prototype engines, is being backed by Moscow's Chemyshev Machine Building Enterprise. In other areas, Soyuz is also demonstrating its 1,000lb-thrust R-125 for use on UAVs, as well as flight testing of the upgraded, R-195 powered Su-25SM.
