Embodiment Construction

[0017] As shown in Figure 1, the characteristics of system 1 are: H 2 / O 2 The steam generator 2 produces superheated steam used to support the compression system in the aircraft and the starter mechanism used to start the engine, as described below.

[0018] h 2 / O 2 The steam generator 2 is well known; it is mainly used for steam sterilization, temperature control of bioreactors, food, packaging materials, medical appliances, textiles and solutions, and it is also used for producing purified water in the pharmaceutical industry.

[0019] h 2 / O 2 The steam generator 2 comprises a system in which hydrogen and oxygen (or air) react with each other in a controlled manner to generate steam. Specifically, H 2 / O 2 The steam generator 2 generates a stoichiometric hydrogen / oxygen mixture according to the principle of jet propulsion, which is combusted in a controlled manner to form steam.

[0020] As shown in Fig. 1, the system further comprises a cooling unit 3 in order to...

Abstract

A system comprises an H2 / O2 steam generator (2) for generating superheated steam which is either fed directly to a gas turbine (8) to bring it to a rotary speed that is sufficient to result in a compressed-air ratio in the gas turbine that allows operation of the gas turbine with a fuel, or which superheated steam is fed to a compressed-air generator (4) for generating compressed-air, wherein the generated compressed-air is fed to a compressed-air system (7), for example of an aircraft, or is used for starting a gas turbine or for other compressed-air systems.

Description

[0001] This application claims priority to U.S. Provisional Patent Application 60 / 600,502, filed August 11, 2004, and German Patent Application 102004039019.3, filed August 11, 2004, the disclosures of which are hereby incorporated by reference . technical field [0002] The present invention relates to a system for generating compressed air, in particular from superheated steam, for supplying into the compressed air system of an aircraft and for starting e.g. an aircraft engine gas turbine. Background technique [0003] The gas turbine must generate sufficient speed of rotation before the pressure ratio is sufficient to operate the gas turbine on the fuel. Today, gas turbines are primarily started by mechanical drives, for example by means of electric starters, or gas turbines are started pneumatically. However, self-contained electric starting of gas turbines such as aircraft engines requires very high electrical power and particularly heavy starter motors. The pneumati...
