Abstract:
1. A method for enhancing a start of a turbine engine for reliably and rapidly reaching a stable operational regime, the turbine engine having an exterior and an interior comprising a compressor for ingesting and compressing air, a turbine coupled to the compressor, and at least one combustion chamber provided with a controlled mixture of compressed air from the compressor and fuel from a fuel feed system, to allow start of a combustion process when ignited, the method comprising providing at least one replaceable ignition module including at least one solid combustible substance that when ignited, causes release of hot gases rich in oxidizing species, or at least one decomposing oxidizer substance that when heated, releases hot gases rich in oxidizing species, coupling the at least one replaceable ignition module in sealed releasable retention and in fluid communication to the at least one combustion chamber of the turbine engine, initiating ignition of the at least one solid combustible substance or of decomposition of the at least one decomposing oxidizer substance and consequent release of hot gases rich in oxidizing species, ducting the hot gases rich in oxidizing species into the at least one combustion chamber to start the combustion process by ignition of the air and fuel mixture, and exhausting combustion products via the turbine, whereby the hot gases rich in oxidizing species start and enhance the combustion process for reliably and rapidly reaching a stable operational regime, wherein the at least one replaceable ignition module further includes at least one exhaust port coupled in fluid communication via at least one turbine starting conduit to the turbine or via at least one compressor starting conduit to the compressor.
