Abstract: A fireproof assembly for an aircraft engine, comprises a fireproof housing having an internal volume and an opening. A fireproof internal shield is located within the fireproof housing. The internal shield divides the volume into a first sub-volume and a second sub-volume, the first sub-volume configured for receiving a component of the aircraft engine. A non-fireproof component seals the opening of the fireproof housing. Fireproof fasteners are used to support internal shield inside the housing.

Abstract: A gasket providing electrical conductivity between components is disclosed. The gasket comprises a body having a fastener hole extending therethrough and an electrically conductive insert lining at least part of the fastener hole in the body. The insert has a first contact face disposed for electrically contacting a first component and a second contact face disposed for electrically contacting a second component. The first contact face is in electrical communication with the second contact face.

Abstract: Variable rate ignition method and system that take advantage of knowledge and analysis of environmental conditions and/or operational conditions. A variable ignition rate for igniting the engine permits an optimal use of the igniters and thereby prolongs their life as well as its associated maintenance schedule. Operating costs and durability are also enhanced. Furthermore, flexibility is enhanced since any changes to the method of determining the best spark rate can be made through update in the software of the engine controller instead of change in the hardware (e.g., the exciter).
