Coupling method and structure for a propulsion system hot section

Abstract:

The present disclosure is directed to a method and structure of coupling a flameholder assembly to a hot section of a propulsion system, such as an afterburning exhaust section. The propulsion system includes an outer casing and an inner casing defining a flameholder assembly disposed radially within the outer casing. The method includes providing a housing defining a retaining rod and groove into which a structural member attaches; providing a retaining plate defining an opening through which the structural member is extended; coupling the structural member to the retaining rod of the housing and the outer casing of the propulsion system; and coupling the retaining plate to the housing and the inner casing of the propulsion system such that the structural member is retained between the housing and the retaining plate.
