1. 16. Flight Dynamics Software Industrialisation for Inclined Orbits

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

   Författare :Pierrick Houede; [2023]
   Nyckelord :flight; dynamics; software; FDS; geostationary; orbit; station; keeping; uncontrolled; inclination.;

   Sammanfattning : The geostationary orbit has many applications for Earth observation and telecommunications. Like all satellites, spacecraft in this type of orbit are affected by perturbations. These perturbations can modify the satellites trajectories and, without control, deviate them from their target position. LÄS MER

3. 17. Tools and Challenges in Evaluating Control Surface Airworthiness for a Blended-Wing-Body UAV

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

   Författare :Anton Åkesson; [2023]
   Nyckelord :;

   Sammanfattning : For transport aeroplanes the Blended-Wing-Body (BWB) configuration shows promise in improving aerodynamic efficiency. The Green Raven project strives to demonstrate hydrogen fuel-cell-electric propulsion on a 4 m wingspan BWB. LÄS MER

4. 18. Design and Analysis of Non-symmetric Satellite Constellations

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

   Författare :Jomuel Danilo Costales; [2023]
   Nyckelord :Space; Satellite; Constellation; Coverage; Non-symmetric; Walker; Set Cover problem; Greedy algorithm; Space; Satellit; Constellation; Täckning; Icke-symmetrisk; Walker; Set Cover problem; Greedy algoritm;

   Sammanfattning : Satellite constellation design has been a well-studied problem since the beginning of the space age. In recent years new concepts and approaches tried to solve it with fewer satellites whilst guaranteeing coverage to the areas of interest, whether globally or regionally. LÄS MER

5. 19. Numerical analysis of a bearing strength in delaminated composite joint

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

   Författare :Olavi Kukkonen; [2023]
   Nyckelord :Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

   Sammanfattning : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

7. 20. Evaluation of IMO second-generation intact stability criteria and examination of different fishing vessel designs to dead ship condition and excessive acceleration failure mode

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

   Författare :Pavlos Liatsis; [2023]
   Nyckelord :Ship Design; Second Generation Intact Stability Criteria; Excessive Acceleration; Fishing Vessels; Skeppsdesign; andra generationens intakt stabilitetskriterier; kraftiga acceleration; fiskefartygsskrovs;

   Sammanfattning : The main objective of this project is to investigate the applicability of the IMO second-generation intact stability criteria in enhancing the process of designing fishing vessels, which often face stability challenges due to their narrow hulls and harsh operating environments. The study involves analyzing the impact of these criteria, specifically focusing on dead ship conditions and Level 1 and Level 2 excessive acceleration criteria, on the design of three fishing vessels.
