  1. 1. 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

  2. 2. 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.

  3. 3. 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

  4. 4. Performance Prediction Program for Wind-Assisted Cargo Ships

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Martina Reche Vilanova; [2020]
    Keywords : ;

    Abstract : Due to the accelerating need for decarbonization in the shipping sector, wind-assisted cargo shipsare able to play a key role in achieving the IMO 2050 targets on reducing the total annual GHGemissions from international shipping by at least 50%. The aim of this Master’s Thesis project is todevelop a Performance Prediction Program for wind-assisted cargo ships to contribute knowledgeon the performance of this technology. READ MORE
