摘　　要：研究了大弧厚球扁药成型工艺及其在大口径火炮高装填密度装药中的应用可行性。自由装填试验表明：采用大弧厚球扁药能有效提高装填密度。经钝感处理后，对该药形进行３０ｍ ｍ 航炮射击试验，当球扁药在装药中的装填比例提高到一定程度时，与制式装药相比，初速增加了 ２．１％ ，而最大膛压基本保持不变，点火安全。１００ Ｈ 射击试验表明：该药形经钝感处理后，应用于大口径火炮高装填密度是可行的、有效的。This paper deals with the forming technique of the oblate spherical powder and the feasibility of applying it to the large caliber gun propellant charge with high loading density. The free loading test results in simulated cartridge show that the use of oblate spherical powder could be applied to increase the loading density effectively. The 30mm antiaircraft gun firing test results by using the deterred oblate spherical powder show that the muzzle velocity increases 2.1% more than that of the standard charge, as the loading proportion of the oblate spherical powder in the charge increases to some degree, while the maximum chamber pressures remain almost constant. The ignition of the charges is safe. The results of 100H shot show that it is feasible and effective to apply this kind of propellant shape deterred to the large caliber gun propellant charge with high loading density.
