CD-3发射装药低易损性能试验研究

Experimental Study on Low Vulnerability of CD-3 Propellant Charge

为了降低发射药的敏感性,以Bu-NENA为增塑剂,FOX-7和RDX作为填充物研制了一种新型硝化棉(NC)基发射药(GD-3发射药),对其装药进行了低易损性能测试研究。试验结果表明,GD-3发射装药在慢速烤燃和快速烤燃、子弹撞击刺激源下发生了V类燃烧反应,在特定的空心装药射流刺激下发生了III类爆炸反应。GD-3发射药在刺激源下易损性响应剧烈程度弱于硝基胍发射药和单基发射药,该新型装药符合低易损性弹药的性能评定要求。

In order to reduce the sensitivity of gun propellants,a new kind of NC based gun propellant(GD-3 propellant)was developed with Bu-NENA as plasticizer and FOX-7 and RDX as energy additives.Low vulnerability test of its charge was carried out.Results show that combustion response V of GD-3 propellant charge occurs in slow cook-off test,fast cook-off test and bullet impact test,and explosive response III occurs in shaped charge jet impact test.Vulnerability response of the GD-3 propellant is the most insensitive under stimuli compared with that of nitro-guanidine propellant and single-based propellant.The new charge meets the performance evaluation demands of low vulnerability ammunition.
