1. Rocket Jet Impinging on a Surface
Master-uppsats, KTH/Teknisk mekanikSammanfattning : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. LÄS MER
2. Investigation on how additive manufacturing with post-processing can be used to realize micronozzles
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Ångström Space Technology Centre (ÅSTC)Sammanfattning : This is predominantly a qualitative study on the manufacturing of micronozzles with an additive manufacturing (AM) technique, namely the laser-powered powder bed fusion (PBF-LB). Manufacturing of micronozzles with standard microelectromechanical system technology often results in 2. LÄS MER
3. Magnetic nozzle plume plasma simulation through a Particle-In-Cell approach in a 3-D domain for a Helicon Plasma Thruster. : A collaboration with REGULUS project T4i Technology for Propulsion and Innovation s.p.a.
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Recent advances in plasma-based propulsion systems have led to the development of electromagnetic Radio-Frequency (RF) plasma generation and acceleration systems, called Helicon Plasma Thrusters (HPT). One of the pioneer companies developing this new type of space propulsion is T4i Technology for Propulsion and Innovation s.p.a. LÄS MER
4. 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
5. Probabilistic Multidisciplinary Design Optimization on a high-pressure sandwich wall in a rocket engine application
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : A need to find better achievement has always been required in the space industrythrough time. Advanced technologies are provided to accomplish goals for humanityfor space explorer and space missions, to apprehend answers and widen knowledges. LÄS MER
