معرفی پایدارکننده ها در پیشرانه های جامد دو پایه

Autocatalysis decomposition of single and double-base propellants is caused to production of nitrogen oxides radicals. Produced radicals, meantime reducing the inner energy of propellant, increased the decomposition process. To restriction of this process, some materials were added to propellant formulation as a stabilizer. Common stabilizers are toxic therefore, decreasing the toxicity and enh...

مروری بر روش های بهبود خواص مکانیکی پیشرانه های جامد مرکب بر پایه GAP (علمی-ترویجی)

GAP propellants has good performance due to high energy of this polymer. Unfortunately, due to poor flexibility of GAP polymer and presence of rigid and conjugated azide side groups in its structure, they have poor mechanical properties especially under low temperatures. This article deals with methods of improving mechanical properties of solid composite propellants based on GAP through changi...

بررسی نرم کننده های پرانرژی در پیشرانه های جامد (علمی-ترویجی)

In modern energetic propellant formulations, conventional plasticizers are being gradually replaced by energetic plasticizers having nitro, nitroamino, azido and other energetic groups. Energetic Plasticizers used to improve processing, mechanical properties and index of energy. Designer of propellant for decrease migration and improve safety factors in propellant’s formulation should to notice...

مروری بر پیشرانه های جامد غنی از بور

Metal powders are combined due to high heat reaction with oxygen, improve the density of the propellant, decrease the pressure exponent (n) and Higher combustion heat, and as a result of higher ISP in propellant. Aluminum, magnesium and boron have found a wide application in propellant formulations. Boron, due to high oxidation heat and low atomic weight, is one of the best elements known. Unfo...
