6. Resonance Mitigation in the Attitude Control of a Flexible Large Solar Sail
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This project is about the design process of a resonancemitigating algorithm for a large solar sail. The solar sail isa structure made up by four long booms in a cross patternwith suspended sails between the edges of the booms. Thespacecraft in this report is controlled using smaller rotatingsails at each tip of the booms. LÄS MER
7. Sensor system for pressure measuring over a sail : Construction and implementation of a sail pressure measuring system
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. LÄS MER
8. Experimental Investigation of the Aerodynamics of a Sailing Cargo Vessel with Four Rigid Wingsails under Unsteady Sailing Conditions
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Wind propulsion is a traditional way to propel ships over the oceans. In the recent development towards more sustainable shipping, sailing is considered in the industry again with high momentum. For a modern merchant ship, the aerodynamic forces generated on the particular rigging are unusual. LÄS MER
9. Energy Sail Ships
Kandidat-uppsats, KTH/EnergiteknikSammanfattning : Oceans offer a vast supply of energy through ever-present winds and currents. Offshore wind energy alone could provide many times the current global energy demand. One concept approach that aims to tap into these reserves are energy sail ship, wind powered vessel that take advantage of oceanic energy to produce and store harvested energy. LÄS MER
10. Barn vill veta
Uppsats för yrkesexamina på grundnivå, Malmö universitet/Fakulteten för lärande och samhälle (LS)Sammanfattning : Vår studies huvudsakliga syfte har varit att analysera, tolka och reflektera hur ett urval pedagoger ser på sitt arbete med livsfrågor i förskolan. Anledningen till ämnet har sin grund i vår egen erfarenhet av att ämnet oftast tystas ner och inte pratas särskilt mycket om. LÄS MER
