【摘要】 采用多点起爆方式,设计了带尾翼翻转型爆炸成形弹丸(EFP)试验装置。用X光和SVR数字相机拍摄了EFP的外形和速度;用多层纸靶测试了EFP在不同飞行距离时的飞行姿态;进行了EFP穿靶能力的检验;并利用泡沫和锯末进行了EFP的软回收。由试验结果知,EFP速度为1.56~1.72km/s,长径比最大达到了3.69,由药型罩转变为EFP的质量转换率达到了98%,EFP具有较好的尾翼结构和气动稳定外形。该EFP能穿透厚度为50mm的厚钢靶或厚度为6mm、间距各为1m的5层薄钢靶。

【Abstract】 The test set of the Explosively Formed Projectile (EFP) with star shaped tail was designed with a multi-point initiation. The shape and velocities of the EFPs were measured by the flash X-ray photograph or a SVR digital camera. The flying posture at different points in the penetration experiment were determined with the multi-layer paper target. The EFPs were recovered by foam and sawdust, and their penetration capacity was tested too. The measured velocity of the EFP is 1.56~1.72 km/s. The maximum length/radius ratio is 3.69. And the mass conversion ratio from the liner into EFP is up to 98%. The EFP has a good star shaped tail structure and a aerodynamic stable shape. The EFP has the ability to penetrate a thick steel target of 50 mm or a five-layered thin steel target with a thickness of 6 mm for each.
