本文主要介绍改善潜艇水下发射导弹的稳定性和弹道的方法。利用这种方法，可在导弹头锥部附近设置排气装置，从而在导弹的背风面（相对于潜艇的航行方向）形成空气覆盖层。这样，潜艇在以巡航速度或接近巡航速度航行时无须减速就可发射导弹。 This article mainly introduces the methods to improve the stability and trajectory of underwater launched missiles. With this method, an exhaust device may be provided near the missile’s head cone to form an air blanket on the leeward side of the missile (relative to the submarine’s sailing direction). In this way, the submarine can launch missiles without slowing down while cruising at or near cruising speeds.
