Directory: commercial engines Model Max thrust (lb) Power max (SL) (shp) Notes/Description (inc submodel) Application Snecma made major strides towards developing a home-grown regional turbofan when it began test runs in mid-year of an all-new core, dubbed Dem 21. The demonstrator forms the basis for Snecma's proposed SM146 turbofan, a 13,5001b to 17,500lb-thrust engine aimed at several proposed next-generation regional twinjets including the Russian Regional Jet. The French manufacturer established a joint venture to develop the SM146 in 2001 with NPO Saturn and TslAM, the Russian institute of aviation motors. In February 2002 it followed this up by establishing a Moscow-based design office to compliment the SM146 project, known as Smartec. However, the economic downturn has put on ice the French government's plan to sell a 25% in Snecma. No revised public offering schedule has been issued. Snecma's financial health took a turn for the worse in the first half of 2002 when revenues dropped 9% to €3.09 billion ($3.02bn), but the order backlog has remained at a more optimistic €10.5 billion. SM146 15,000 Turbofan - proposed for Russian Regional Jet Czech-based Walter continues to produce the rugged M601 turboprop and is delivering limited numbers of the 560kW-rated M601E-11 variant for a Raytheon King Air C90 re-engining programme set up by Wisconsin-based Performance Conversions. While Walter has set up a US-based subsidiary, Walter America, in Arkansas, modifi cation centres are being set up by Performance Conversions in Wisconsin, Brazil and New Zealand. Both the US and Brazilian STCs for the Walter conversion were grant ed in 2002, and the agreement between the two companies was formalised with the formation in Prague of the Aircraft Conversion and Upgrade Alliance (ACUA). This will support other Walter turboprop conversions, and augments Walter's standard support of its M601 family now in service in more than 50 countries. The business is badly needed by Walter which has been forced to diversify into making everything from parts of the Rolls-Royce Trent engine family to hip and knee joint implants.

Three of the engines are for new commercial applications, one of which was the EJ22 intended for the Eclipse 500. However, following development issues, Eclipse terminated its contract with Williams in late November. The company is now looking for a new application for the engine. The company is now fielding or developing the FJ33 for the ATG Javelin and Adam Aircraft A700, the FJ44-1 for Cessna's Citation CJ1, and the FJ44-2 for the CJ2, Raytheon Premier 1 and Sino-Swearingen SJ30 2. The higher-thrust FJ44-3 is also destined for the new CJ3 which is set for certification in the second quarter of 2004, and is in competition with P&WC's PW615F for Cessna's Mustang entry-level jet. As well as new applications, the FJ44 family has been selected or is being considered for several re-engining cam paigns. The FJ44-2 is first off the mark, having been selected for the Sierra Industries and Garrett Aviation Services Eagle II re-engining of the Citation 500/501 SP-series and the "Spirit Wing" Learjet re-engining effort. The FJ33, a 0.8 scale version of the FJ44, builds on new manufacturing and design technology developed for the NASA- sponsored FJX-2 which, in turn, is now the EJ22 for the Eclipse 500. The FJ33, which achieved its full thrust rating of around 1,5001b on its first run, is due to achieve certification at the end of 2004. The FJ44-3, FJ33 and FJ22 are strictly Williams International products with the FJ44-1 and -2 having a 15% participation from Rolls-Royce.
