Data.
Chinese scholar's peace booth exists《Influence of the thermite to double-base solid propellant laser ignition characteristic》In one text, pass through electricity
Combustion surface state after the completion of incendiary agent burning of the observation of scarnning mirror method containing alumina particles, the shortcoming of this method is to fire
Influence of the alumina particles of burning state to the burning of solid propellant likely differs from the influence for completion of having burnt, using this side
Method can not accurately learn influence of the alumina particles burnt to solid propellant.
Fang Chong and Li Shu fen exist《Experimental Research of the Effects of
Superfine Aluminum Powders on the Combustion Characteristics of NEPE
Propellants》In one text, propose that the method for thermogravimetric analysis has speculated burning shape of the ultra-fine alumina particles in solid propellant
State, changes according to the product quality before and after burning, thus it is speculated that the metal alumina particles in solid propellant are outermost layer in burning
Aluminium surface can be oxidized agent oxidation, but do not photograph true fired state of the alumina particles in solid propellant yet.
Chinese scholar Zhao Zhi it is rich et al.《The specificity analysis of NEPE high-energy solid propellant condensed-phase combustion products》In one text,
Research is fired state of the micron-sized aluminium powder in solid propellant, using X-ray, the method for electric competing scanning and DTG
Deduce micron aluminium powder and burnt and may explode in solid propellant, but they do not photograph a micron aluminium yet
Real fired state of the particle in solid propellant.
