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

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Casper Liavåg; [2023]
    Keywords : Cryogenic Pressure Vessel; Blast; Blast Loading; Pressure Vessel; Launch Infrastructure;

    Abstract : 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. READ MORE

  3. 2. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Gustav Blomgren; Ebba Carlsson; [2023]
    Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

  4. 3. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

    University essay from KTH/Kraft- och värmeteknologi

    Author : Birgir Steinn Hermannsson; [2022]
    Keywords : ;

    Abstract : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. READ MORE

  5. 4. Prediction of Detonation Performance of CHNO Explosives

    University essay from KTH/Kemi

    Author : Anders Abrahamsson; [2022]
    Keywords : Detonation pressure; Detonation velocity; Electrostatic potential; Crystal density; Heat of formation; Detonationstryck; Detonationshastighet; Elektrostatisk potential; Kristalldensitet; Bildningsentalpi;

    Abstract : Produktion av nya energetiska material är dyrt. Målet med detta arbete är att utveckla en metod som uppskattar Chapman-Jouget detonationstrycket och detonationshastigheten hos nya CHNO-sprängämnen. READ MORE

  6. 5. Asymmetries in shaped charges

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Boman; [2021]
    Keywords : ;

    Abstract : This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shock­compression results in a jetof metal being shot forward in up 10km/s. READ MORE
