Turbine aero-engines of the world ©„„ „„ [FDJ11MJ compilation by MIKE HIRST EVEN a derivative gas-turbine engine programme for a modern airliner typically costs £250 million to launch, and the cashflow which has to be sustained, especially during early production life, can be considerably in excess of this figure. In terms of employ ment, capital investment and technological risk therefore, the aero-engine is frequently as daunt ing a programme as the airframe it powers. Even so, there is no shortage of types, and the air frame designer has a wide choice, whether he is concerned with large or light, military or civil air craft. This directory complements the light gas-turbine directory pub lished in Flight for January 19, 1980. It covers engines in produc tion or under development that are rated at more than 10,0001b (44-5kN) thrust or 2,000 e.h.p. (l,492kW) power output. Some discretion has been necessary in the case of engines which enjoy civil and military applications, and some types which are no longer in production but which occupy im portant corners of the market have been included. This directory is in seven major sections (see contents opposite). For the first time we present a separate section on the Soviet Union's engines. Leading data on important engines are also proj vided in the data tables. Major events since Flight's last engine directory include the launch of Pratt & Whitney's PW2037 (previously called JT10D), the USAF's decision to retrofit a single KC-135 tanker with CFM56s and Rolls-Royce and Japan's announcement of RJ.500.
