    摘要: A low vulnerability ammunition (LOVA) propellant is prepared with a polyurethane binder and a mixture of nitramines consisting essentially of RDX and at least 7.5 wt. % HMX (based on combined oxidizer binder matrix weight). Dilution of RDX with HMX enhances precure extrudability of the propellant grain. Polymerization and extrudability is provided without slumping prior to total cure given a NCO:DIOL:TRIOL equivalent ratio of from about 110:15:85.

    摘要: A solventless method for the preparation and storage of uncured low vulnerability ammunition propellant (LOVA) includes blending from about 60 to 80 weight percent of either HMX or RDX oxidizer having a weight mean diameter from 1.0 to 14 microns with a polyurethane binder. A cure effecting amount of cure catalyst may also be included. These ingredients are blended at a temperature below about 110.degree. F., deaired, and optionally stored at low temperatures at a pre-cured condition, extruded and subsequently cured. The products produced thereby have uniquely low burning rates as well as uniquely low burning rate exponents.

    摘要: An arming fuze for ordnance type munitions having but one movable part comprising a solvent desensitized liquid explosive contained in a ported (ventilated) cavity that is normally sealed by a sleeve. Upon movement of the sleeve and exposure of the liquid explosive within the cavity to the air, the liquid explosive loses a volatile solvent, the desenistizing agent, and becomes progressively more sensitive. A first embodiment is that of an inertia armed nose fuze for a projectile wherein the desensitized liquid explosive is enclosed in the cavity in a porous solid matrix. Upon rapid acceleration, as when the projectile is fired, the sleeve undergoes set-back thereby exposing the porous matrix to a violent slip stream of air and to a strong desiccating action. The liquid explosive rapidly loses solvent to the air, rapidly becoming more sensitive whereby it is impact sensitive by the time impact on the target occurs. A second embodiment is that of a contact fuze for mine munitions wherein the fuze is armed by manually moving the sleeve to uncover the ventilation ports thereby to allow the solvent to leave the explosive liquid. When the explosive liquid has "dried", it is rendered sensitive to pressure or shock whereby detonation occurs upon striking or crushing the fuze.

    摘要翻译: 一种用于弹药型弹药的装甲引信,其具有一个可移动部件,其包含通常由套筒密封的带通式(通风)空腔中的溶剂脱敏液体炸药。 当套筒移动并将空腔内的液体炸药暴露于空气中时,液体炸药会失去挥发性溶剂,脱苯剂,并逐渐变得更加敏感。 第一实施例是用于抛射体的惯性武装鼻子引信,其中脱敏的液体炸药被封闭在多孔固体基质中的空腔中。 当快速加速时,就像抛射弹射击一样,套筒会发生回弹,从而将多孔基体暴露于暴风的空气流中,并产生强烈的干燥作用。 液体爆炸物迅速向空气中流失溶剂,迅速变得更加敏感,由此受到对目标的时间影响的冲击敏感。 第二个实施例是用于矿山弹药的接触引信,其中引信通过手动移动套筒来露出通风口,从而允许溶剂离开爆炸性液体。 当爆炸性液体“干燥”时,会对压力或冲击敏感,因此在引爆或击打引信时会发生爆震。

    摘要: A roll calendered sheet propellant features thin sheets of solid propellant which have been consolidated by the calendering operation. After calendering, the sheet propellant is roll-printed or "coined" with a pattern, which forms propellant flakes after ignition in a gun/cannon system. The printed pattern consists of a designed flake geometry, for example, of contiguous diamond or square shapes providing flame communicating paths therebetween. The formation of propellant flakes depends upon a characteristic of propellants, specifically that they burn faster in zones of high residual stress. By varying the design of the roll printer, the printed pattern, in a two-sided printed sheet configuration, may include a cut in the pattern of the order of 15 to 40% of the propellant sheet uncut web depth. After roll printing, the propellant may be cut to length and rolled for insertion into a shell or cartridge case.

    摘要: A chisel point striker is retained by a shear pin on the center line of a warhead above an open-ended flash tube packed with a percussion sensitive priming mixture. Impact of the warhead with a resistant target causes the shear pin to shear and the striker to impact the target violently thereby to set off the priming mixture. The resulting blast wave is communicated via two paths in opposite directions to two separate detonation wave acceptors or boosters. Each booster accepts the detonation wave and communicates a detonation reaction to a main explosive charge of the warhead.
