1. 1. Scania’s Packaging Network : Analysis of the Environmental Impact of Alternative Fuels and Modalities Within the Transportation Network

   University essay from KTH/Industriell produktion

   Author : Pietro Astori; Jóhanna Blöndahl Guðmundsdóttir; [2022]
   Keywords : Logistics; sustainability; alternative fuels; alternative modalities; sustainable packaging; Logistik; hållbarhet; alternativa bränslen; alternativa metoder; hållbara förpackningar;

   Abstract : In a fast-moving world with high demand for deliveries of various goods, the need for high performing transportation systems and networks has grown rapidly. As a reaction, the number of trucks has increased, which together with other transport solutions to cover the need has caused a growth of CO2e emissions. READ MORE

3. 2. UV Curable Polymers for use in Additively Manufactured Energetic Materials

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexis Delorme; [2022]
   Keywords : Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

   Abstract : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. READ MORE

4. 3. Formulation and Assessment of Hexamethylene-tetramine Filled Solid Fuel Grains

   University essay from KTH/Fiber- och polymerteknologi

   Author : Mårten Schollin; [2021]
   Keywords : Hybrid rocket; solid fuel grain; hexamine; pot-life; tensile properties; Hybridraket; fast raketbränsle; hexamin; härdningstid; dragegenskaper;

   Abstract : Hybridraketer har inte sett så mycket användning som dess motsvarigheter som använder flytande eller fasta drivmedel. De främsta orsakerna kan förklaras med att hybridraketer historiskt sett haft lägre regressionshastighet och bränsletäthet. Inverkan av nackdelarna har dock minskat tack vare fortsatt forskning rörande hybridraketer. READ MORE

5. 4. Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle

   University essay from KTH/Rymdteknik

   Author : Måns Rasmussen; [2021]
   Keywords : Air-launched; Launch Vehicle; Three-staged; Rocket; Sun-Synchronous orbit; Solid propellant; Liquid propellant; Trajectory optimization; Nonlinear programming; JAS 39 Gripen; Fighter aircraft; Luftlanserad; Trestegsraket; Solsynkron bana; Fast bränsle; Flytande bränsle; Bananalys; Icke-linjär optimering; JAS 39 Gripen; Jaktflygplan;

   Abstract : The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage.

6. 5. Conceptual Design of an Air- launched Multi-stage Launch Vehicle

   University essay from KTH/Fysik

   Author : John Sigvant; [2020]
   Keywords : Air-launched; multi-stage; launch vehicle; rocket; LEO; solid propellant; optimization; Luftuppskjutning; flerstegsraket; låg omloppsbana; fast bränsle; optimering;

   Abstract : In the present thesis, the objective was to find the maximum amount of payload mass that can be put into a 500 km polar orbit by a 1400 kg air-launched multi-stage rocket launched from a fighter jet platform. To fulfill the objective an algorithm incorporating several modules was developed. READ MORE
