Fully automated rudder pedal system for ultralight aircraft

Sammanfattning: The Swedish ultralight aircraft manufacturer, Blackwing Sweden AB, has requested a reinvention of their adjustable mechanism for the rudder pedal system in the BW600RG aircraft. The current manual system is insufficient in terms of a non-ergonomic adjustment process which requires for the aircraft to be stationary. The ambition of this project was to deliver a concept covering a fully automated adjustment mechanism which can be initiated at a stationary state as well as during flight. In addition, the concept was to acquire an airworthiness certification which is necessary for implementation in the aircraft. By following the principles of Ulrich & Eppinger’s design process, a concept which satisfies the main project goal was developed. The results from the validation analysis showcased that the proposed solution is functional, while a few additional actions of work are necessary in order to fully incorporate it. These actions include: selecting fasteners, selecting a linear actuator of suitable size and lastly, designing a mounting rig for the linear actuator. By completing the additional requirements, a strength-test can be performed which subsequently allows for certification and thus for implementation of the fully automated rudder pedal system in the BW600RG aircraft.
