The results showed that the performance of unchoked ducted rocket is superior to that of choked one. When the gas generator is loaded with high burning-rate exponent fuel-rich propellant, the performance of unchoked ducted rocket is almost the same as that of the ducted rocket working under fixed mass ratio of fuel to air.

研究结果表明：非壅塞固体火箭冲压发动机的性能显著优于燃气流量不可调的壅塞式固体火箭冲压发动机；当贫氧推进剂具有高的燃速压强指数时，非壅塞固体火箭冲压发动机的性能接近燃气流量完全调节、以等空燃比工作的冲压发动机性能。

The carbon dioxide fire extinguishing system is able to put gas fire out after the gas supply source is cut, and it is also able to put out liquid fire, solid fire of fusible materials such as paraffin and asphalt, solid surface fire, deep-seated solid fire such as wincey, fabric, and paper, and electric fire, etc.

The nature of coupling between combustion and fracture are twofold in the convecting combustion process of crack cavity. On the macroscopic scale; the coupling appears as the energy and mass transforming between the solid phase of the cracked body the gas phase of the flow field. On the microscopic scale, the coupling induces the evolution of the microstructures, which leads to degradation of mechanical properties of solid materials.

从燃烧断裂耦合的内在形式来看，包括两大方面的内容：在宏观表象上，表现为在含能材料裂纹的对流燃烧过程中，固相裂纹体和对流燃烧流场之间的质能交换形式的热力耦合；在微细观运动方面，热和力的作用诱发固体材料微细观运动和组分、结构的变化，最终改变固体材料的宏观力学性能，表现为固体材料的热力损伤过程。
