【摘要】 研究了含铝、含细ＡＰ固体推进剂中铝粉对推进剂表面的辐射热反馈，得出这种热反馈是使该推进剂燃速压强指数上升的主要原因之一，在配方中添加超细铝粉可能减低压强指数的上升。更多还原

【Abstract】 The contribution of radiative heat feedback of aluminum to burning surface is studied. It is found that heat feedback of aluminum is the main cause of pressure exponent rising in aluminumized solid propellant adopting fine AP, and that using superfine Al powder may assuage the pressure exponent rising更多还原
