改性双基推进剂热老化燃烧性能试验研究与寿命预估

The Experimental Study on the Thermal Aging Combustion Property of the Composite Modified Double Base Propellant and its Life Time Calculation

采用密闭性燃烧器法对老化后的改性双基推进剂测定了燃烧性能 ,利用获得的燃速随老化时间变化的曲线计算了其贮存寿命 ,并与用中定剂法计算的贮存寿命进行了比较 ,两者吻合较好 ,说明推进剂燃速老化试验较真实地反映了改性双基推进剂的老化性质。

By using the closed combustion apparatus, the thermal aging combustion property of the composite modified double base propellant was measured. Then the storage life was calculated based on the experimental results. Comparing with the storage life calculated by using the centralite wastage method, the consistency of the two results shows that the experiment of the propellant burning rate versus aging time veritably demonstrates the aging property of the propellant.
