1. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters
University essay from KTH/Matematik (Avd.)Abstract : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. READ MORE

2. Primary flight control design for a 4-seat electric aircraft
University essay from KTH/FlygdynamikAbstract : This thesis work is part of a design process which aims to develop a four-seathybrid-electric aircraft at Smartflyer (Grenchen, Switzerland). In that scope,various mechanisms of the plane had to be developed, including the systemactuating the control surfaces. READ MORE

3. Optimal configuration of the mechanical structure and flap actuator for hydrofoils
University essay from KTH/Maskinkonstruktion (Avd.)Abstract : Hydrofoil vessels are becoming more popular and driving marine development forward. Since the water friction is greatly reduced, they allow achieving higher speeds and electrification of the boats. FoilCart is a full electric active controlled hydrofoil boat designed as a research project at KTH. READ MORE

4. Accuracy of transient versus steady state forces on a rudder operating in a propeller slipstream
University essay from Umeå universitet/Institutionen för fysikAbstract : In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of a rudder is transient in nature, and rudder design using CFD may therefore become very time-consuming. READ MORE

5. Utveckling och validering av propellermodell baserat på rörelsemängdskälla för ett friströmningsfall
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : Propellersimulering genom Computational Fluid Dynamics (CFD) används mer och mer i ett tidigt designstadium gällande fartygs framdrift. Rolls-Royce Hydrodynamic Research Centre har lång erfarenhet av propellerdesign och analysarbete genom både modelltester och numerisk simulering, och CFD används idag för ett flertal olika tillämpningar och syften.
