Optimization Based Design Methodology for Heavily Loaded, Large Stroke Flexure Hinges

Traditional kinematic joints used in large scale machinery consist of multiple rigid parts in contact, which causes wear and imposes the need for lubrication and maintenance. Compliant joints have the potential to eliminate these problems as they require less maintenance. However, these joints are not studied for large scale applications with...

Choosing a sustainable, economical energy supply system, considering all operational variables of an autonomous submarine dredger: A study as part of the development of the ALERD, which will serve as sustainable coastal maintenance in the service of The Netherlands

The Autonomous Low Energy Replenishment Dredger (ALERD) strives to revolutionize the dredging world. The ALERD operates autonomously underwater, which saves energy during the dredging process and transit. Autonomous underwater operation drives the need of alternative energy facilities. However, due to the energy savings of dredging, alternative...

Ready for Take-Off: Scaled Flight Testing

Atmospheric free flight scaled flight testing is an affordable way to investigate the dynamic properties of an aircraft, while enabling a wider range of test possibilities than a windtunnel. This research is the first step into the development of a scaled flight testing model and as such will highlighted the difficulties and discrepancies which...
