| 摘要: |
| 采用调节硝酸酯增塑聚醚(NEPE)推进剂的配方组分、添加燃速调节剂等手段开展了降低环氧乙烷-四氢呋喃共聚醚/硝化甘油/硝化二乙二醇/黑索金/高氯酸铵(P(E-CO-T)/NG/DEGDN/RDX/AP)类NEPE推进剂燃速的研究。结果表明,增大AP粒径、降低NG/DEGDN的比例、适当降低AP含量、添加少量燃速调节剂,可达到降低燃速的目的。通过对NEPE推进剂配方组分的调节,在燃速调节剂三醋酸甘油酯/聚甲醛/蔗糖八醋酸酯以1∶1∶1配比添加时,其7.0 MPa下的燃速可降至6.87 mm/s。 |

| Abstract: |
| Reducing burning rate of nitrate ester plasticized polyether(NEPE) propellant was studied by means of adding some burning rate modifiers and adjusting its composition.The results show that burning rate of the propellant can be depressed by enlarging the particle size of AP,reducing the ratio of NG/DEGDN,decreasing the content of AP and adding little content of burning rate modifiers.The burning rate under 7.0 MPa can be reduced to 6.87 mm/s with ratio 1:1:1 of burning rate modifiers glycerol triacetate/polyoxymethylene/sucrose octa-acetate. |
