Reinforced combustion of the ZrH2-HMX-CMDB propellant: The critical role of hydrogen
Chemical Engineering Journal, 2020Abstract Metal hydrides, which are capable of producing H2 and release much energy efficiently via combustion, are regarded as promising high-energy fuels for future advanced solid propellants. Here, we report our first attempt on the application of a high-density hydride ZrH2 in CMDB propellants containing the high-energy explosive HMX and the ...

Effect of Al content and particle size on the combustion of HMX-CMDB propellant
Combustion and Flame, 2020Abstract In solid propellants, aluminum plays a key role in energy performance enhancement, but it also induces combustion problems such as low combustion efficiency and agglomeration. Herein, we study the effects of Al on the combustion properties of low-signal composite-modified double-base (CMDB) propellants.

Combustion of HMX‐CMDB Propellants (II)
Propellants, Explosives, Pyrotechnics, 1985AbstractThe burning rate characteristics of HMX‐CMDB propellants were examined as a function of HMX concentration. In the region of low HMX concentration, below about 50%, the burning rate decreases with increasing the HMX concentration. However, in the region of high HMX concentration, above about 50%, the burning rate increases with increasing the ...

Ballistic Modification of RDX‐Based CMDB Propellants
Propellants, Explosives, Pyrotechnics, 1988AbstractThe effect of lead and copper salts and certain metallic oxides was studied on the burning rates of RDX‐based CMDB propellants in the pressure region 35–105 [kg/cm2]. Lead methylene disalicylate (LMDS), basic copper salicylate (BCS). cobaltic oxide and lead stannate produced higher burning rates by 10%–16%.

Combustion Effects of Nitrofulleropyrrolidine on RDX‐CMDB Propellants
Propellants, Explosives, Pyrotechnics, 2014AbstractThe effect of N‐methyl‐2‐(3‐nitrophenyl)pyrrolidino[3′,4′:1,2]fullerene (mNPF) on the decomposition characteristics of hexogen (RDX) was investigated using differential scanning calorimetry (DSC). The results show that mNPF can accelerate the decomposition of RDX, the peak temperature (Tp) of the exothermal decomposition is reduced by 6.4 K ...
