2. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. LÄS MER

4. Däck-mark Interaktion hos skogsmaskiner
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today’s machines. LÄS MER
