      Nevstad, Gunnar Ove (2002)
      PBXN-109 has been produced with French I-RDX and two types of Dyno produced RDX and tested with regard to shock sensitivity. Other tested properties are viscosity/pot-life and mechanical properties. The shock sensitivity ...
    • Driftskostnadsvekst i Forsvaret 

      Gulichsen, Steinar (2003)
      In long term defence planning it is of vital importance to have knowledge of how the operating costs will evolve over the period of analysis. This knowledge will help decision makers in planning investment and operating ...
    • Mid-infrared laser source - operators guide 

      Stenersen, Knut; Haakestad, Magnus; Arisholm, Gunnar (2002)
      A mid-infrared laser source, based on an optical parametric oscillator pumped by a Nd:YVO4 laser at 1.06 μm wavelength, is described. The nonlinear material is periodically-poled lithium niobate (PPLN). The source operates ...
    • Materiellrelatert driftskostnadsvekst i Forsvaret 

      Kjernsbæk, Hans Martin; Vamraak, Tore; Bruun, Tor Erling (2005)
      Cost escalation is a subject of great impact on long term defence planning, and estimating a cost escalation factor for future cost modelling is therefore important. The historically observed cost escalation is an important ...
    • Digital multistatisk radar - overordnet maskinvarebeskrivelse 

      Tansem, Ivar; Gundersen, Rune; Bjordal, Halvor; Johnsen, Terje; Johnsrud, Steinar; Olsen, Karl Erik; Sørnes, Per K. (2002)
      This report gives a high level description of a radar demonstrator made for demonstrating bistatic radar. The demonstrator consists of one transmitter and one receiver unit. An overview of the hardware used in the ...
    • Contact surface area of a pyrotechnical granular material 

      Moxnes, John F.; Eriksen, Svein W. (2002)
      The pyrotechnic composition RS-41, a mixture of 49wt% KCLO4, 49wt% Al/Mg and 2wt% Calcium Resinat, is an important ingredient in the Multipurpose (MP) ammunition. RS-41 is placed in front of the projectile and ignites due ...
    • Inverse modeling of penetration into 12.7 cartridges 

      Moxnes, John F.; Nilssen, Jan R. (2002)
      In this article a study of the forces caused by penetration of steel penetrators into cartridges of brass has been carried out. Experimental data was compared with simulations using the Nike-2D code and with solutions ...
    • A model of internal ballistics properties in gun tubes 

      Moxnes, John F. (2002)
      In this report a study of the pressure generated by burning of gunpowder in gun barrels has been carried out. Calculations using the model were compared with experimental results and with results from the standard ...
    • Radardekningssimulator - fysikk 

      Olsen, Karl Erik (2002)
      Project 726 has developed a multistatic radar coverage prediction tool for frequencies above 100MHz. Various physical effects such as reflection, diffraction, refraction, attenuation due to precipitation and atmospheric ...
    • Bottom reverberation predictions with the acoustic model Lybin - a comparison between three bottom backscattering algorithms 

      Sevaldsen, Erik (2002)
      Comparing the three bottom backscattering algorithms we observe variations in the resulting bottom reverberation levels from 0 to more than 20 dB in some cases. Concentrating on the variations at shorter to medium ranges ...
