带孔底窝弹是在项目设计中为解决增程问题而提出来的研究课题。众所周知,普通底窝弹能增程,增程量约为2～4％。本文提出的带孔底窝弹,增程量可达10％,且射击精度有较显著的提高。它通过在海双-57弹上的实弹射击、风洞吹风、章动角测定及雷达测速等对比试验,无可辩驳地显示了带孔底窝弹在气动力和外弹道方面所具有的异常的优越性。 With a hole in the bottom of the bomb is in the project design to solve the problem of extended range proposed research topics. As we all know, ordinary bottom bombs can increase the range, increase the amount of about 2 ~ 4%. In this paper, the hole-in-the-hole bombs, increased by up to 10%, and the shooting accuracy has been significantly improved. It is an irrefutable demonstration of the aerodynamic and external trajectory abnormalities of the hole-in-socket missile through the comparison of live fire, wind tunnel blowing, nutation angle measurement and radar speed measurement on the sea dual-57 bomb The superiority.
