摘要:
A propellant for guns includes at least one energy carrier, nitrocellulose and cellulose acetate butyrate. At least part of the nitrocellulose is alcohol-soluble nitrocellulose. The nitrocellulose serves as a binder and for that purpose is present in a concentration of at least 15% by weight in the propellant. A process for producing a propellant is also provided.
摘要:
The invention provides an infra-red decoy flare comprising a pyrotechnic composition which comprises an extrudable and energetic binder in an amount in the range of from 4-35 wt %, which binder comprises a nitrocellulose, an oxidator in an amount in the range of from 40-80 wt %, a pyrotechnic fuel in an amount in the range of from 15-35 wt %, and a carbon source in an amount of up to and including 10 wt %, all amounts based on total pyrotechnic composition. The invention further provides a process for preparing said infra-red decoy flare.
摘要:
The present invention comprises a solid double-base propellant composition having on a weight basis from about 2 to about 23 percent of a light metal fuel, from about 14 to about 35 percent of a particulate solid oxidizer, from about 12 to about 35 percent triaminoguanidinium hydrazinium diazide and from about 30 to about 50 percent of a plasticized nitrocellulose binder.
摘要:
The present invention comprises a solid double-base propellant composition containing on a weight basis from about 5 to about 40 per cent of a crystalline substantially non-solvated aluminum hydride, from about 21 to about 33 per cent nitronium perchlorate and from about 30 to about 60 per cent of a plasticized nitrocellulose binder.
摘要:
A composite, double-base, solid rocket propellant composition which utilizes beryllium hydride as a high energy fuel in combination with a nitro-nitrate ester plasticizer. The particular ester plasticizer used in the propellant composition serves to produce the high non-equilibrium flame temperatures needed for attaining high beryllium hydride combustion efficiencies.
