- 摘要:
- 研究了凝胶DT-3的流变特性、流量特性，利用凝胶DT-3推力器试验件进行了热试车。结果表明，凝胶DT-3在试验温度范围内表现出剪切稀化的非牛顿流体特性；温度、压降和几何结构对凝胶DT-3的流变特性有明显影响；适当增加毛细管喷注器直径有利于凝胶DT-3的流动及雾化；试验件点火工作正常，室压稳定，比冲性能为液体DT-3的90％。
- Abstract:
- Rheological and flowing characteristics of gelled monopropellant DT-3 have been investigated. According to the hot tests results, gelled monopropellant DT-3 is a kind of shear shinning non-Newtonian fluid in the range of the experimental temperatures. Temperature, pressure drop and geometric structure have effects on the rheological characteristics of gelled monopropellant DT-3. Properly increasing of injector diameter can get better flowing and spray characteristics for the gelled monopropellant. Hot tests show that specific impulse of experimental thrusters is lower than that of liquid DT-3.
