1. 1. End User Study of an Engineering Design Tool

   Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Ina Johnson; Ann-Sofie Eriksson; [2023-09-21]
   Nyckelord :user frustrations; case study; re-engineering;

   Sammanfattning : [Context and Motivation] PROSIT+ Designer is a Volvo Group-developed application focused on operational development for vehicle production. Since its launch, 15 years ago, PROSIT+ Designer has not had any major revisions or updates. [Question/problem] The frustrations from end users are, as a result, piling up. LÄS MER

3. 2. Design and Implementation of a Rocket Launcher Hybrid Navigation

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Omar Ugolini; [2023]
   Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

   Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

4. 3. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Vikramjeet Das; [2023]
   Nyckelord :rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

   Sammanfattning : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. LÄS MER

5. 4. RECOMMENDATIONS FOR A DEPENDABLE ROV SYSTEM FOR SWEDISH MARITIME RESEARCH

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :David Bernström; Erik Nyström; [2023]
   Nyckelord :;

   Sammanfattning : A Remotely Operated underwater Vehicle (ROV) faces many problems regarding dependability and most issues come during launch and recovery. The thesis looks at finding what dependability aspects shall be considered when developing a modular ROV to come up with recommendations for a system, together with a more reliable method of launching and recovering ROV’s.

7. 5. Finite-Element Analysis of Cryogenic Pressure Vessels Under Blast Loading

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Casper Liavåg; [2023]
   Nyckelord :Cryogenic Pressure Vessel; Blast; Blast Loading; Pressure Vessel; Launch Infrastructure;

   Sammanfattning : The behavior of cryogenic double-walled pressure vessels, such as thoseused in space launch vehicle infrastructure, under blast loading is a somewhatunderstudied topic. This is of interest due its implications on, among otherthings, launch site design and safety in the event of a launch vehicle failure. LÄS MER
