“…[238][239][240][241][242] Several parameters need to be evaluated, including thermal stability, heat of decomposition, activation energy (E a ) and reaction models as well as chemical pathways of thermolysis. [243][244][245][246][247] As mentioned above, CNMs have large SSAs, excellent thermal conductivity and superior electroconductivity. Therefore, they are capable of promoting thermochemical reactions, for example, catalyzing the decomposition of energetic compounds including RDX, HMX and AP.…”

“…What has to be sampled and from which part of the flame it should be sampled are the issues considered in detail in [23][24][25][26]32]. The problem of gas sampling from an isothermal flow of the mixture with the degree of conversion increasing along only one spatial coordinate Z was solved theoretically in [32].…”

“…The techniques and results of mass-spectrometer studies in the gas phase of combustion waves were described in [23][24][25][26][27][28][29][30][31]. The combustion products were extracted from the gas phase by miniature samplers and were analyzed with a time-of-flight mass spectrometer [23][24][25][26] or with a quadrupole mass spectrometer [27][28][29][30][31].…”

Application of a microthermocouple technique is justified; results on physics of combustion of condensed explosives, in particular, RDX and HMX, obtained by this technique are briefly described. The possibilities of mass-spectrometer (including gas sampling) and optical techniques of studying the chemistry of gas-phase processes in the combustion wave are analyzed with RDX and HMX used as examples. The measured results are briefly discussed. Constrains of the techniques are indicated. A method of refining the chemistry of combustion-wave processes is proposed.

Focusing on a new kind of solid propellants, which takes the ammonium dinitramide (ADN) as the high‐energetic oxidant, and 3,3‐bis(azidomethyl)oxetane and tetrahydrofuran copolymers (PBT) as the high‐energetic fuel binder, the burning rates and the theoretical performance of the propellant were measured under different ADN contents, ADN sizes and pressures. The burning rates increased from 7.9 mm/s to 117.4 mm/s and 49.1 mm/s to 74.2 mm/s when the pressure increased from 0.1 MPa to 10 MPa and from 12 MPa to 20 MPa separately, with a singularity in the pressure dependence of the burning rate at around 10 MPa. In terms of the effect of the ADN content, under the experiment pressures from 0.5 MPa to 5.0 MPa, the burning rates of the propellant were promoted by the increase of the oxidizer loading in a range of 50 wt% to 75 wt%, with a transition from a kinetically‐controlled reaction to a diffusion‐controlled one. Within the condition scope of this study, no obvious effect of the ADN sizes on the propellant combustion properties was observed. This could be attributed to the solid‐liquid mixed multiphase layer and the binder which served as a heat sink for the smaller ADN particles.
