[ 1 ] - بررسی مکانیسم سوختن یکنواخت و کاهشی در پیشرانه های جامد دوپایه(علمی-ترویجی)
Solid propellant burning rate is highly dependent on the pressure, so that the combustion duration propellant rocket engines, combustion vibration leads to considerable changes in pressure. This could lead to an explosion in rocket engines. The best case is propellant combustion independent of pressure. Ballistic modifiers added to propellant formulation for reduce pressure sensitivity and re...
[ 2 ] - کاربرد‌های روش فرا صوت در ارزیابی موتور های پیشرانه جامد(علمی-ترویجی)
Ultrasonic technique, is one of the best nondestructive techniques for solid propellants motors evaluation. In this article ultrasonic technique use, has been reported for measuring solid propellant burning rate at different pressure with just one experiment and at the moment, for especial motors. The use of swept frequency method in a proper confine frequency and interrupted frequency method h...
[ 3 ] - تاثیر استفاده از آمونیوم پرکلرات با دو اندازه (درشت و ریز) بر ویسکوزیته پیشرانه جامد مرکب(علمی-پژوهشی)
Concentrated suspension of binders in composite propellant causes a complex phenomena so that controlling of rheology properties is difficult due to high percentage of fillers. Composite solid propellant contains paste suspension of mixtures of different components, e.g. oxidizer, fuel and binder. Increasing the percentage of solid phase without increment of viscosity is an important subject in...
