  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. Master thesis within light warhead for support weapon : Investigation of defects, methods and requirement specifications in order to get a shell body shatter free

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Adam Jansson; [2016]
    Keywords : warhead; support weapon; shell body; shatter free; defect; method; carbon fibre; epoxy; crack; delamination; porosity; CFRP; CFRE; NDT; verkansdel; understödsvapen; granathylsa; splitterfri; defekt; metod; kolfiber; epoxi; spricka; delaminering; porositet; OFP;

    Abstract : At launching the shell body, especially the backplane of the shell body, will be exposed to very high stresses due to acceleration, pressure and increased temperature from the propellant combustion. Defects in the shell body could in worst case for example result in high temperature gas leakage into the warhead and thereby ignite the explosives before exiting the launcher. READ MORE
