(2001)Rapporten beskriver målinger og analyser av akselerasjoner på Stridsbåt 90N foretatt vinteren og sommeren 2001. Akselerasjonsnivåene som er observert er sammenholdt med grenseverdier for akselerasjonsbelastninger i ... -
Målinger av akustisk støy fra kandidater til nytt artilleri i 2016
(2016-05-20)I januar 2016 testet Forsvaret fire kandidater til nytt artilleriskyts. Artilleri er det mest støyende skytevåpenet Forsvaret har. Støy fra artilleri er derfor avgjørende for hvordan støykartene rundt et skytefelt ser ... -
Målinger av hastighetsfelter i flygenererte virvler nær hus under innflyvningstraseen ved Kjevik flyplass
(2001)Winds caused by aircraft generated vortices are measured close to a roof in the approach to Kjevik airport. It is reported that aircraft vortices have caused tiles to fall down from roofs. In this report measurements of ... -
Målinger av lydtrykket i nærfeltet til en rifle
(2005)This report is part of an ongoing effort to improve the ability of the Norwegian Defense Estate Agency (FB) to assess noise pollution from ring ranges. Here we provide documentation of measurements done at Norwegian ... -
Målinger av lydtrykket nær CV90, AGL, 12.7, Rena
(2007)Denne rapporten er del av et pågående arbeid for å forbedre Forsvarsbygg sin evne til å evaluere støynivået rundt skytefelt. Her dokumenterer vi målinger som ble gjort på Rena 11. mai 2006. Der ble det målt tidsserier ... -
Målinger av lydtrykket nær lette våpen, Terningmoen, revidert utgave
(2006)This report is part of an ongoing effort to improve the ability of the Norwegian Defense Estate Agency to assess noise pollution from ring ranges. Here we provide documentation of measurements done at Terningmoen 17 ... -
Målinger av lydtrykket nær M109, 155 mm felthaubits
(2007)Denne rapporten er del av et pågående arbeid for å forbedre Forsvarsbygg sin evne til å evaluere støynivået rundt skytefelt. Her dokumenterer vi målinger som ble gjort nær Hjerkinn 21. september 2006. Der ble det målt ... -
Målinger av utslipp fra maskingevær aktuelle for anskaffelse i Forsvaret
(2015-10-15)Forsvaret skal anskaffe nye maskingevær kaliber 7,62 og i den sammenheng har Forsvarets forskningsinstitutt (FFI) fått i oppdrag av Forsvarets logistikkorganisasjon (FLO) å måle utslipp av gasser og metaller fra aktuelle ... -

(2001)The purpose of this document is to give a top-level overview of the work that is to be undertaken in workpackage 2.2, anti-ship missile defenc e, in project 795. It describes how the tasks are to be solved with respect ... -
MCX-6100 CH 6027/14 charcterization
(2015-11-18)MCX-6100 is a composition developed and produced by Chemring Nobel AS. It is a melt-cast composition primarily applicable as filler in large calibre munitions like 120 mm and 155 mm. We have characterized MCX-6100 from ... -
Measurements and analysis of fluctuations in the Earths magnetic field in a coastal water area - originally presented at Marelec 97, June 1997
(2006)Forsvarets forskningsinstitutt accomplished in September 1991 a pilot study investigating fluctuations in the earth's magnetic field in a coastal water area in Norway. The experimental data was collected during seven days ... -
Measurements of directivity of the pressure field near rifles with and without flash suppressor
(2012-04-02)We have measured the time series of the pressure, with and without flash suppressors. The measurements were done 84 cm from the muzzle of four rifles, in 159 directions between 3 and 161 degrees to the firing direction. ... -
Measurements of hydrocarbon flame propagation in a channel
(2021-05-25)Assessing the risk of gas explosions associated with Li-ion batteries in confined geometries is challenging. When a Li-ion battery cell undergoes so-called thermal runaway, internal reactions in the cell can lead to the ... -
