1. A plant for the generation of mechanical energy by using a fluid, the plant comprising:
- (a) a gas turbine;
(b) a plurality of compressor units;
(c) a plurality of compressor turbines for driving the compressor units, the compressor turbines being connected in series with the compressor units;
(d) a combustion chamber connected with the gas turbine, the expanded air from the compressor turbines being directed into the combustion chamber;
(e) a main heat exchanger being disposed between the compressor turbines and the compressor units, the exhaust from the gas turbine being directed through the main heat exchanger;
(f) an interim heat exchanger being disposed between the compressor units;
(g) a first external heat exchanger being disposed downstream of the main heat exchanger; and
(h) a second external heat exchanger being disposed between the last compressor turbine and the combustion chamber of the gas turbine;
wherein the first and the second external heat exchangers enable a predetermined h/p ratio to be achieved between the thermal power given off in the interim and the external heat exchangers and the mechanical power delivered to the gas turbine.

Abstract
A plant for the generation by means of a gaseous fluid of mechanical energy comprising an assembly consisting of a gas turbine (1) with a combustion chamber (4) and a compressor unit (C) driven by a turbine (T). The turbine (T) is fed by compressed air from the unit (C) after its passage through a main heat exchanger (3) arranged in the exhaust of the gas turbine (1). The outlet (10) of the compressor-turbine (T) is in fluid communication with the combustion chamber (4).
