METHOD AND SYSTEM FOR ENHANCING START OF A TURBINE ENGINE

摘要

A method, a system, and a product for enhancing the start of a turbine engine by providing a replaceable ignition module (57) including a solid combustible substance, that when ignited, or a solid oxidizer substance, that when heated, releases hot gases rich in oxidizing species. The module includes a solid substance(s) appropriately selected as: a solid-propellant grain (SPG) and a solid oxidizer (SO); or an oxygen-rich burning substance (OBSS); or a solid-propellant grain and an oxygen-rich burning substance; or an oxygen-rich burning solid substance and a solid oxidizer. The replaceable module further contains an initiator (67) for the initiation of the solid combustible substance, or solid-propellant grain by an initiation command (IC). The hot gases released by the ignition module start and enhance the combustion process of the air-and-fuel mixture by successive fuel heating and vaporization, followed by ignition.
