摘要 为减少某发射装药的燃烧残片,对可燃紧塞元件的强度及燃尽性开展了试验研究,对比测试了传统纸质紧塞元件及可燃紧塞元件的压缩力,通过火炮输弹上膛冲击试验及野战公路运输试验测试了采用可燃紧塞元件的发射装药的结构强度;通过密闭爆发器试验测试了可燃紧塞元件的表观燃速,并通过内弹道射击试验验证了可燃紧塞元件的结构强度及膛内燃尽性。结果表明,可燃支撑筒的压缩力约为纸质支撑筒的两倍;可燃紧塞盖的压缩力约为原纸质紧塞盖的40%,约为原纸质支撑筒的80%,可燃紧塞元件力学强度可保证该发射装药在运输过程及供输弹过程中的结构完整性;在50~150MPa下,可燃紧塞元件的线燃速为ADiGu发射药燃速的8倍以上,在同一燃烧环境下,可燃紧塞元件可先于发射药在膛内燃尽;射击后炮口无燃烧残片,在内弹道过程中燃烧完全,无二次火焰,炮口无残留。 To reduce the combustion debris of certain gun propellant charge,the experimental research of mechanical intensity and combustion completeness for combustible seals was carried out.The compression of combustible seals and conventional papery seals were measured and compared.The structure strength of gun propellant charge with combustible seals was tested by gun loaded ramming impact test and transportation test on field road.The apparent burning rates of combustible seals were tested by a closed bomb test.The structure strength and combustion completeness of gun propellant charge with combustible seals were validated by an interior ballistic test.The results show that the compression of combustible underprop is two times as conventional paper underprop.The compression of combustible cover is about 40% as conventional paper cover,and about 80% as conventional paper underprop.The mechanical intensity of combustible seals can meet the structure integrity of gun propellant charge in ramming and transportation process.Under the pressure of 50-150 MPa,the burning rate of combustible seals is 8 times faster than that of ADiGu gun propellant.The combustible seals can be burnt before gun propellant under the same burning environment in bore.And there is no combustion debris in front of muzzle after firing.The combustion in the interior ballistic process is complete without second flame and residue in front of muzzle.
