A method for implementing a system and a device for enhancing the starting process of a turbine engine by use of at least one solid mass of oxidizing-species-releasing material, ORM, selected as a solid oxidizer, or SO, and/or as an oxidizing-species-releasing burning substance, or ORBS. The ORM is introduced into the combustion chamber of the turbine engine and the starting process of the turbine engine is initiated, by help of the igniter and in association with the mass of ORM, to enhance the starting process. In operation, an ORM selected as an SO releases gaseous oxygen when heated to decompose, while an ORM chosen as an ORBS discharges oxidizing species when ignited to burn. An ORM such as an SO or an ORBS may operate alone or in various combinations of both. The ORM is configured to release a predetermined mass flow rate of oxidizing species or of gaseous oxygen.
