Data B : Engine Data File

Turbofan engine manufacture is dominated by three large companies, General Electric (GE), Pratt and Whitney (P&W), and Rolls Royce (RR). Each of these companies have formed joint-ventures or collaborative arrangements with other engine companies and sometimes between themselves. Examples of such arrangements are:- BMW and RR, Allied Signal and GE (CFE), Snecma (France) and GE (CFM International), GE and P&W (to develop the New Large Aircraft engine), P&W plus RR plus MTU (Germany) and JAE (Japan) forming International Aero Engines (IAE), and Williams with RR, (Williams-RR). Apart from the 'big three' and the joint ventures there are several individual manufacturers who produce mainly less powerful turbofans. These include Allied Signal, Allison and Pratt & Whitney Canada (a separate company to the large USA manufacturer). The original USSR engine manufacturers now trade independently under their own company names, these include Aviadvigatel/Perm Motors (Russia) and ZMKB Progress (Ukraine).

Technical and operational data on current and projected engines from engine manufacturers has been compiled from brochures and other published information. The following tables list the engine type, thrust (in lb.) and aircraft applications for each manufacturer.
