1,3-Diazido-2-nitro-2-azapropane (DANP) and 1,7-diazido-2,4,6-trinitro-2,4,6-triazaheptane (DATH) were synthesized, thoroughly analyzed, and their explosive properties and sensitivities toward friction and impact were measured. The precursors 1,3-diacetoxy-2-nitro-2-azapropane (1), 1,3-dichloro-2-nitro-2-azapropane (3), and 1,7-dichloro-2,4,6-trinitro-2,4,6-triazaheptane (4) – as well as DATH – were furthermore characterized by X-ray diffraction.

Preparation, Characterization, and Sensitivity Data of Some Azidomethyl Nitramines

A propellent charge powder for barrel-type weapons having a plasticizer on the basis of nitramine and nitrocellulose, nitramine and energetic and non-energetic plastic binders, or nitrocellulose or an explosive, and wherein the plasticizer is a mixture of at least two chemically different dinitro diaza compounds. The plasticizer facilitates the production and use of the propellent charge powder possessing a low temperature coefficient.

Propellent charge powder for barrel-type weapons

This paper reports the evaluation of four different energetic plasticisers, viz., glycidyl azidepolymer (GAP, MW = 390), 1,5-diazido-3-nitrazapentane (DANPE), ethylene-glycol-bis-azido-acetate (EGBAA) and N-n-butyl-N-(2 nitroxyethyl) nitramine (n-Bu-NENA) separately into highenergy gun propellant containing 28 per cent NC (13.1 N %), 65 per cent RDX, 6 per cent di-octyl-phthahate (DOP) and 1 per cent carbamite.  Four different propellant compositions based on theenergetic plasticiser have been formulated separately with the replacement of non-energeticplasticiser, DOP. The propellants were processed by standard solvent method and evaluatedexperimentally along with the control composition to determine the ballistic parameters, cal-val,sensitivity, thermal characterisation, thermal stability and mechanical properties. The performanceof the propellants containing the energetic plasticiser has  been compared with that of thecontrol composition containing the non-energetic plasticiser, DOP so as to assess the suitabilityof the energetic plasticiser for the futuristic gun propellant formulations. It has been found outthat n-Bu-NENA is the superior plasticiser among the four energetic plasticisers evaluated inthis study.

Evaluation of Energetic Plasticisers for Solid Gun Propellant

A gas-generating module for an airbag utilized in motor vehicles, which includes a gas-generating composition and an igniting composition arranged within a container. The gas-generating composition is presently in the shape of a foil-like layer or coating, or alternatively consists of a granulate, and is constituted from components which are a mixture of a composition which is based on a metal azide and an oxidizing agent; a first binder for the granulation of the composition; a second elastic binder and a rapidly combusting igniting mixture whereby the elastic foil layer is arranged in a casing which is pressure-resistant up to a specified degree and which consists of a relatively gas-tight fabric.
