根据美澳合作NULKA悬浮诱饵弹资料分析,需要研制新型干扰弹,悬浮高度、速度、时间等局部指标已经超过NULKA。为了解决舰船上干扰弹发射尾焰对舰船结构的冲击和烧蚀问题,确保干扰弹发射的可靠性,设计了“锥形”涡流导流装置;文中涉及的关键技术是根据导弹燃气流场计算来确定导流间隙和特殊的排导流线结构。经过外场试验验证了该导流方法设计合理,能够满足舰船使用要求,可以列装到舰船外舷上,形成新的火力点。

According to the data analysis of the U. S. Australia cooperation NULKA suspension decoy missile, it is necessary to develop a new type of jamming missile; the local indexes of suspension height, velocity and time have exceeded NULKA. In order to solve the impact and ablation of the tail flame of the jamming missile on the ship and ensure the reliability of the rocket launching, the eddy current diversion device was designed. The key technology involved in this paper is to determine the diversion clearance and the special structure according to the calculation of missile gas flow field. The field test proves that the design of the diversion method is reasonable and can meet the requirements of ships. It can be installed on the outer surface of ships to form new fire points.
