Wound profiles in soap caused by penetration of high speed spheres
(2002)As a first attempt at identifying a tissue model for use in wound ballistic simulations a study of the wound profiles in soap during deceleration of spherical steel projectiles has been carried out. Experimental data were ... -
Cavity expansion theory applied to the penetration of high speed spheres into weak targets
(2002)As a first attempt at identifying a tissue model for use in wound ballistic simulations a study of the deceleration of spherical steel projectiles in soap has been carried out. Experimental data were compared to numerical ... -
Fremstilling og testing av PBXN-109 med fransk I-RDX
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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 ... -
Rekonfigurerbar prosseseringsmodul - IOkort
(2002)This is a flexible multipurpose IOcard designed for fast prototyping, including the multipurpose programmable processing card that are designed. It contains digital IO and analogue IO. -
Rekonfigurerbar prosseseringsmodul - FPGAkort versjon2
(2002)This design is a multipurpose programmable processing card. It is based on three Field Programmable Arrays for Xilinx. This report describes the hardware and layout for usage of this card. -

Interoperabilitet - kostnadsdriver og styrkemultiplikator
(2002)The main aim of this report is to analyse Interoperability (IO) of military forces and the consequences for Norway of more emphasise on IO, both nationally and in NATO. The first part of the report argues that IO is a ... -
Mulige russiske reaksjoner på ulike former for NATO-utvidelse
(2002)NATO is, for the second time, going to include new members from East-Central Europe. In view of the experiences from the first eastward expansion the possibility of a strong Russian reaction was seen as the main obstacle ... -
Digital multistatisk radar, sender og mottaker
(2002)This report describes the receiver and the transmitter designed for verifying a multistatitic radar concept. The digital part of the receiver and the transmitter are based on FPGAs. The report also describes the software ... -
Space-based AIS : theoretical considerations and system parameter optimization
(2006)The recently introduced Universal Automatic Identification System (AIS) is a ship-to-ship and ship-to-shore reporting system based on broadcasting of messages in the maritime VHF band. The AIS messages could also be ...
