پیشرانه جامد مرکب پرانرژیNEPE(علمی-ترویجی)

Nitrate ester plasticized polyether (NEPE) is a new generation of composite solid propellants which its high energy content in comparing with conventional formulations, has attracted many researchers in the defense departments, all over the world. First of all an introduction and history and importance of NEPE propellants will be discussed and formulation and combination of propellants componen...

آزمون های غیرمخرب در پیشرانه های جامد (علمی-ترویجی)

Non-destructive testing methods are used to detecting defects in materials and evaluation of materials properties without causing changes to their usable properties. They are applied in industry to provide the assurance of high quality for semi-manufactured products, final products, devices and materials. Except of many civilian applications they are widely used in rocket and aviation industry ...

افزایش سرعت سوزش پیشرانه با استفاده از صفحات فلزی کار گذاشته شده درون گرین پیشرانه (علمی-ترویجی)

The method of foil embedding is employed in solid propellant motors with end-burning configuration, thereby significantly improving the burning rate of the propellants. These foils provide such amplification by locally augmenting heat feedback from propellant combustion products to unburned solid material, with resultant increase in burning surface area. Burning rate would raise with the incr...

بررسی عوامل مؤثر در انتخاب پایدارکننده برای پیشرانه های جامد دو پایه(علمی-ترویجی)

استفاده از عوامل پیوندی بورات استری در پیشرانه های جامد

Bonding agents are one of the most important components of solid propellants that enhance the interaction between solid particles and binders. Many bonding agents have been reported so far and sufficient laboratory studies have been carried out on their mechanism of action, including, hydantoin, isocyanorathe, vinyl ether, base-shif, etc. Borate esters are other group of bonding agents that mos...
