    Abstract: A gas turbine engine including a composite case having a conductive path therein, and a conductive case connected to the composite case. The conductive case is made of a conductive material. A fastener connects the composite case to the conductive case. The fastener is conductively connected to the conductive material of the conductive case and not directly conductively connected to the conductive path. At least one voltage discharge channeling assembly is connected to the fastener and to the conductive case. The at least one voltage discharge channeling assembly has a portion conductively connected to the conductive path. The at least one voltage discharge channeling assembly is conductively connected to the fastener. A method of assembling an engine casing in a gas turbine engine is also provided.

    Abstract: An electronic controller for an engine and a propeller, a control system and related methods are described herein. The controller comprises a first channel and a second channel independent from and redundant to the first channel. Each channel having a control processor configured to receive first engine and propeller parameters and to output, based on the first engine and propeller parameters, at least one engine control command comprising instructions for controlling an operation of the engine and at least one propeller control command comprising instructions for controlling an operation of the propeller. Each channel also comprises a protection processor configured to receive second engine and propeller parameters and to output based on the second engine and propeller parameters, at least one engine protection command comprising instructions for protecting the engine from hazardous conditions and at least one propeller protection command comprising instructions for protecting the propeller from hazardous conditions.

    Abstract: There is described herein methods and systems for testing a propeller feathering function. The method comprises monitoring a rotational speed over time of propeller blades of an aircraft, commanding an angle change of the propeller blades, comparing a post-angle change rotational speed of the propeller blades to an expected rotational speed without the commanded angle change and obtaining, by the processor, a rotational speed difference, and issuing a test passed signal when the rotational speed difference exceeds a threshold and a test failed signal when the rotational speed difference does not exceed the threshold.
