FRANGIBLE GEARBOX CENTER GUIDE SUPPORT SYSTEMS AND METHODS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18132347 titled 'FRANGIBLE GEARBOX CENTER GUIDE SUPPORT SYSTEMS AND METHODS

The assembly described in the patent application is designed to mount an auxiliary component to an engine case of a gas turbine engine. It includes a support bracket with a first end for attachment to a first flange of the engine case, a second end for attachment to a second flange of the engine case, and an intermediate portion between the two ends. A bearing member and a locator are also included within the support bracket, along with a frangible ring member made of a porous metal material like frothed aluminum or thin-walled honeycombed aluminum or steel. The frangible ring member is designed to absorb energy during a Foreign Object Damage (FBO) event while limiting system displacement, thus reducing the energy transmitted to the auxiliary component, such as a gearbox housing.

• The assembly includes a support bracket with a frangible ring member made of a porous metal material to absorb energy during a FBO event.
• The frangible ring member limits system displacement, reducing the energy transmitted to the auxiliary component.
• The assembly is designed to mount an auxiliary component to an engine case of a gas turbine engine.
• The support bracket attaches to flanges on the engine case, with a bearing member and locator included for stability.
• The innovative use of a frangible ring member made of porous metal material enhances safety and protection of the auxiliary component during FBO events.

Potential Applications: - Gas turbine engines - Aircraft engines - Industrial turbines

Problems Solved: - Absorbs energy during FBO events - Limits system displacement - Reduces energy transmitted to auxiliary components

Benefits: - Enhanced safety for auxiliary components - Reduced damage during FBO events - Improved protection for engine components

Commercial Applications: Title: Frangible Ring Assembly for Gas Turbine Engine Auxiliary Components This technology can be used in the aerospace industry for gas turbine engines in aircraft and industrial applications. It enhances safety and protection for auxiliary components, reducing the risk of damage during FBO events.

Questions about Frangible Ring Assembly for Gas Turbine Engine Auxiliary Components: 1. How does the frangible ring member made of porous metal material enhance safety during FBO events? 2. What are the potential commercial applications of this technology in the aerospace industry?

Original Abstract Submitted

An assembly for mounting an auxiliary component to an engine case of a gas turbine engine includes a support bracket, the support bracket having a first end configured for attachment to a first flange of the engine case, a second end configured for attachment to a second flange of the engine case, and an intermediate portion located intermediate the first end and the second end; a bearing member disposed within the intermediate portion; a locator disposed within the bearing member; and a frangible ring member disposed between the support bracket and the bearing member, wherein the frangible ring member comprises a porous metal material (e.g., frothed aluminum or thin-walled honey combed aluminum or steel). The frangible material thickness can be set to absorb FBO energy while limiting system displacement during and post FBO event, thus reducing the energy transmitted to an auxiliary component (e.g., a gearbox housing).
