This paper examines the utilisation of aero gas turbines fitted to aircraft which are close to the end of their useful lives. When the aircraft are scrapped the engines can be removed, modified and employed for land or sea applications. The engine chosen as a possible candidate for ‘recycling’ is a two spool bypass engine.

A performance analysis has been carried out, which indicates that this scheme can yield good levels of output and efficiency.

Preliminary examinations indicate that there are economic advantages in converting these engines for other uses. Two possible conversions are examined: one for a pure industrial engine, and one as the gas side of a combined cycle power plant. The results obtained from this feasibility analysis appear attractive; the anticipated cost of purchasing and conversion is predicted to be significantly lower than purchasing new equipment.
