Apparatus for improving the operating efficiency of a gas turbine engine includes a heat pump and a pair of heat exchangers for use in conjunction with the engine. The first heat exchanger is disposed in the flow path of the engine upstream of its compressor section, while the second heat exchanger is disposed in the engine flow path downstream of the compressor section and upstream of the combustor section of the engine. A portion of the work output of the engine is used to operate the heat pump so as to cause cooling of air in the flow path at the first heat exchanger and heating of air in the flow path at the second heat exchanger.

In a gas turbine engine including, in serial relationship, a compressor section, a combustor section and a turbine section, with said turbine section having an output shaft and all of said sections together defining a flow path, initially, for air and, later, for products of combustion through said engine, apparatus for improving the operating efficiency of said engine, comprising: (a) a first heat exchanger disposed within said flow path of said engine upstream of said compressor section; (b) a second heat exchanger disposed within said flow path of said engine upstream of said combustor section and downstream of said compressor section; (c) pumping means interconnecting said first and second heat exchangers so as to cause cooling of air in said flow path at said first heat exchanger and heating of air in said flow path at said second heat exchanger; and (d) means for coupling said output shaft of said turbine section with said pumping means so as to drive the latter with said output shaft.
