Problems solved by technology

Higher inertia is dangerous in this case because, if the temperature rises suddenly, the control does not have time to increase the fluid flow to the turbine

Embodiment Construction

[0032] exist figure 1 In , the gas turbine has a turbine rotor 10 of a turbine 12, which is used to generate output power. The turbine rotor 10 has an output shaft 14 that rotates in the direction indicated by arrow A to drive a useful load (not shown). The turbine 12 is mounted downstream of a compressor 16 for compressing fluid so as to feed fluid into the turbine 12 . The compressor 16 has a compressor turbine 18 having a turntable (not shown) which rotates on a shaft 20 in a direction indicated by arrow B opposite to direction A. As shown in FIG. Fluid leaving the turbine disk 10 enters directly into the rotor of the compressor turbine 18 without any control.

[0033] Combustor 20 supplies heated fluid to turbine 12 . Fluid from the compressor 16 is supplied to the turbine 12 through a heat exchanger 22 having: a first loop 24 connected to the compressor turbine 18; and a second loop 25 arranged at the compression Between machine 16 and turbine 12. The fluid leaving t...

Abstract

A gas turbine engine has a turbine mounted downstream of a compressor and a compressor turbine mounted downstream of the turbine for driving the compressor. The compressor turbine has a rotor disk that is mechanically coupled to the compressor and rotates in a direction opposite to the direction of rotation of the turbine rotor disk. A heat exchanger has a first circuit connected to the compressor turbine and a second circuit connected between the compressor and the turbine. An electric load for taking off a fraction of power produced by the compressor turbine includes an electric generator that is mechanically coupled to the compressor turbine. An electric load controller changes the fraction of power produced by the compressor turbine based on readings from the temperature sensor located in the engine.

Description

[0001] This application may cross-reference three co-pending US applications. Each of these three applications was filed on September 25, 1998, respectively, as U.S. Patent Application Serial Nos. 09 / 161104, 09 / 161114, and 09 / 161115, each of which is incorporated herein by reference . technical field [0002] The present invention relates to the field of gas turbines, and in particular to gas turbines using adjustable load feedback mechanisms to control engine operating parameters. Background technique [0003] The present invention relates to a variable speed gas turbine which is particularly advantageous for driving electrical generators or motor vehicles, and which is preferred for moderate power output, small size and high response speed in other applications. The efficiency of a variable speed turbo varies according to many variables including engine speed. In this prior art gas turbine, when the turbine speed is reduced and the power output remains constant, as in th...
