      Nevstad, Gunnar Ove (2015-12-02)

    • Characterization of M7 propellant properties by closed vessel and calorimeter 

      Nevstad, Gunnar Ove (2012-09-25)
      Two production mixes of M7 propellant for use in M72 –LAW have been tested in closed vessel and calorimeter for determination of any differences with regard to energy content and burning properties. In closed vessel three ...

    • Characterization of MCX-6002 and MCX-8001 

      Nevstad, Gunnar Ove (2015-11-18)
      Knowledge about properties of explosive composition is important regardless of the applications. The performance of explosive compositions depends on detonation velocity and detonation pressure. The munition sensitivity ...

    • Characterization of MCX-8100 

      Nevstad, Gunnar Ove (2015-12-15)
      Independent of application, certain explosive composition properties are important to know. Performance depends on properties like detonation velocity and detonation pressure. Sensitivity of munitions is dependent on ...

    • Cheetah calculations of GA BAMO candidate compositions 

      Nevstad, Gunnar Ove (2015-12-02)
      Norway’s main objective in the EDA project No B-0585-GEM2-GC “Formulation and Production of New Energetic Materials” was to synthesize different new energetic binders built of GA and BAMO polymers. Before starting ...

    • Combustion of RS-41
