An Electromechanically Actuated Nose Landing Gear Using a Dual-Output Motor Control Unit

This paper describes the design, construction and testing of a dual-output power converter concept where the large components, such as the DC link capacitor and heat-sink, are shared between two actuators which are used sequentially in the deployment of aircraft landing gear. This mutual component approach combines the advantages of dual-use power converters with the flexibility of one power converter per application. Practical results of the converter operating are presented for a range of test conditions in order to validate the simulation study.
