| 摘要: |
| 研究了纳米碳酸盐对丁羟三组元、丁羟四组元、低燃速NEPE推进剂燃烧性能的影响。结果表明:纳米碳酸盐使丁羟三组元推进剂在高压(10～18MPa)和低压(4～10MPa)段的压强指数降低到0.2以下,同时使燃速明显降低;使丁羟四组元推进剂在高压段(10～18MPa)的压强指数降低到0.26左右;使低燃速NEPE推进剂的的压强指数(4～9MPa)从0.77左右降至0.55以下。从研究结果可以看出,添加该纳米碳酸盐是降低复合推进剂压强指数行之有效的途径。 |

| Abstract: |
| The effects of nanometer carbonate on the combustion properties of AP/Al/HTPB,AP/RDX/Al/HTPB and low burning rate NEPE propellant were investigated.The results show that,when nanometer carbonate is added,the burning rate pressure exponent of AP/Al/HTPB propellant is decreased to less than 0.2 in the pressure ranges of 10～18 MPa and 4～10 MPa,at the same time,the burning rate is greatly decreased.The burning rate pressure exponent of AP/RDX/Al/HTPB propellant is decreased to about 0.26 in the ranges of 10～18 MPa.The burning rate pressure exponent of low burning rate NEPE propellant is decreased from about 0.77 to 0.55 in the ranges of 4～9 MPa.Thus,the addition of nanometer carbonate is a feasible way to decrease the burning rate pressure exponent of composite solid propellants. |
