The Time Characteristics Making Exact the Screening by Aerodispersion from Smolke Grenade with the Charge Based on Red Phosphorus

摘要

The time of ignition #tau#_r,the time of burning #tau#_h,and the time of burning-out #tau#_d at the definite wave length of radiation being attenuated can be detarmined reliably from time course of attenuation of radiation caused by aerodispersions generated from the smoke protection grenades. In case of grenades being tested containing the smoke mixtures with red phosphorus,the first mentioned time characteristics at the wave length of radiation 10.6 #mu#m were typical by longer values than at the wave length 0.82 #mu#m.With the grenades containing charges of smoke mixture in pressings the maximum attenuation values 0.82 #mu#m were reached at the time of ignition #tau#_r=3 s,at the wave length 10.6 #mu#m approximately up to #tau# =5 s.The mentioned values of ignition #tau# and the time of burning #tau#_h make exact the technical data of screening smokes created from the smoke grenades mentioned.
