| Abstract: |
| In order to choose an optimized heating methods of the thermal safety performance for ammunition structures. The comparison analysis from the aspects of fuel, heating rate, temperature range, temperature controlled, and its effects to ammunition reaction of the open pool fire, controlled propane jet fire, electric heating swathes, electric heating case and infrared radiation lamps array. For fast cook-off test heating methods, the infrared radiation lamps array had the advantages of open pool fire and improved temperature controlled propane jet fire. It could imitated the flame temperature whose temperature region was located 800~1200 ℃, temperature rising rate was not lower than 200 ℃/s, temperature offset was not greater than 5% and had advantage of cleanness and environmental protection. For slow cook-off test heating methods, the infrared radiation lamps array had the advantages of electric heating swathes and electric heating case. It could imitated the slow cook-off temperature whose temperature region was not lower than 400 ℃, temperature rising rate was regulated between 3.3 ℃/h~1.0 ℃/min, temperature domains were not fewer than 4 and could not produce added influence to the reacting degree. Optimized choosing of the fast/slow cook-off heating methods which avoided effecting the reaction degree of ammunition was an important problem for the heating safety test of ammunition structures. |
