Method and system for enhancing start of a turbine engine, and ignition module

A system operative for enhancing a start procedure of a turbine engine having an exterior and an interior, the system comprising:

• the turbine engine having a compressor for ingesting and for compressing air, a turbine coupled to the compressor, 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,
• at least one replaceable ignition module containing at least one solid combustible substance that when ignited, causes generation of hot gaseous oxidizing species, or at least one decomposing oxidizer substance that when heated, releases hot gases rich in oxidizing species, and the replaceable ignition module being coupled in sealed releasable retention and in fluid communication to the at least one combustion chamber,
• at least one initiator also contained in the at least one replaceable ignition module, for initiating ignition of the at least one solid combustible substance or of decomposition of the at least one decomposing oxidizer substance and subsequent generation of hot gases rich in oxidizing species, and
• a chamber passage for ducting the hot gases rich in oxidizing species from the replaceable ignition module into the combustion chamber for starting the combustion process by ignition of the inflammable air and fuel mixture, whereafter resulting combustion products are exhausted via the turbine, and whereby the hot gases rich in oxidizing species generated by the replaceable at least one ignition module start and enhance the combustion process for rapidly reaching a stable operational regime of the turbine engine,
• 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.

A replaceable ignition module configured for enhancing a start procedure of a turbine engine having an interior and an exterior, a compressor for ingesting and for compressing air, a turbine coupled to the compressor, and at least one combustion chamber receiving compressed air from the compressor and providing a controlled inflammable mixture of air and fuel dosed to allow start of a combustion process when ignited, the replaceable ignition module comprising:

• a module housing encasing at least one solid combustible substance that causes generation of hot gases rich in oxidizing species when ignited, or at least one decomposing oxidizer substance that when heated, releases hot gases rich in oxidizing species, the module housing being coupled in sealed releasable 15 retention and in fluid communication with the at least one combustion chamber,
• at least one initiator for initiating ignition of the at least one solid combustible substance or of decomposition of the at least one decomposing oxidizer substance and subsequent generation of hot gases rich in oxidizing species, and
• a chamber passage for ducting the hot gases rich in oxidizing species into the at least one combustion chamber for starting the combustion process by ignition of the inflammable air-fuel mixture, whereafter resulting combustion products are exhausted via the turbine, whereby the hot gases rich in oxidizing species released by the at least one replaceable ignition module start and enhance the combustion process for rapidly reaching a stable operational regime of the turbine engine,
• 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.
