Intellectual Property India Publishes Patent Application for Aircraft Turbine Engine Assembly Comprising An Emergency Device For The Mechanical Coupling Of Two Rotating Parts Of The Assembly

MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617090605 A) filed by Safran Helicopter Engines on July 24, 2026, for Aircraft Turbine Engine Assembly Comprising An Emergency Device For The Mechanical Coupling Of Two Rotating Parts Of The Assembly.

Inventors include Auduberteau, Alexandre; Chabanne, Pierre; Boisseleau, Denis Daniel Jean; Marsaudon, Mathieu Jean-Baptiste; and Habrant, Baptiste.

The application for the patent was published on October 23, 2026, under issue no. 43/2026.

Abstract: The invention relates to an assembly (100) for an aircraft turbine engine (1), the assembly comprising: - a first turbine engine part (20) and a second turbine engine part (22), wherein each of the parts is rotatable about a longitudinal central axis (X) of the assembly; - a main device (24) for mechanically coupling the first part (20) to the second part (22), wherein the main device is configured, in a normal operating configuration of the assembly, to mechanically couple the first part (20) to the second part (22) in translation along the longitudinal central axis (X) of the assembly; - an emergency device (124) for mechanically coupling the first part (20) to the second part (22), wherein the emergency device (124) comprises a shaft (126) that comprises: - a first coupling portion (128) fixed to or integrated into the first part (20); - a second coupling portion (132) comprising at least one emergency axial stop (134), and, in the normal operating configuration of the assembly, in which the emergency device is in an inactive axial coupling state, the emergency axial stop (134) is axially spaced from a complementary axial stop (136) provided on the second part (22); wherein the assembly is configured such that, in the event of a failure resulting in an undesired axial separation between the first and second parts (20, 22), the emergency device (124) switches to an active axial coupling state in which axial retention of one of the first and second parts relative to the other is ensured by the emergency axial stop (134) coming into contact with the complementary axial stop (136).
