对装甲车辆的有效防御主要取决于精确投射的战斗部。新型末制导战斗部目前都在研制之中，这种战斗部能大幅度地改善命中精度，因此具有良好的效果．一个实例就是ＥＰＨＲＡＭ末制导炮弹，它采用先进的探测和控制系统，以达到最佳结果．智能弹药的重要研制工作在于气动和控制特性的确定．对于ＥＰＨＲＡＭ，已做了静态和动态风洞实验．为了认证本制导概念和根据飞行试验识别气动参数和推力干扰效应，研制了一种可回收的装有测试仪表的试验型弹药．该试验弹几次从直升机提升的平台上做了降落试验。在这些首次试验期间，弹上装有简化了的敏感器设备．其目的在于检验该末制导炮弹的性能，得到了所期望的扫描地面轨迹．这些飞行试验的分析确认了在小攻角情况下静态风洞试验的结果．对于大攻角情况下系统性能的识别。已安排了更多次飞行试验的日程，在那些试验中将装全套仪器和选用的推力程序，以充分激发该弹动力学问题。
The effective defense of armored vehicles mainly depends on the precise projection warhead. The new terminal warhead is currently under development, this warhead can greatly improve the hit accuracy, it has good results. An example is the EPHRAM terminal guidance projectile, which uses an advanced detection and control system to achieve the best results. The important development of smart ammunition is the determination of pneumatic and control characteristics. For EPHRAM, static and dynamic wind tunnel experiments have been done. In order to certify this guidance concept and to identify aerodynamic parameters and thrust disturbing effects based on flight tests, a test prototype that can be recuperated with test instrumentation was developed. The test projectile made several landing tests on a helicopter-lifted platform. During these first experiments, the projectile was equipped with a simplified sensor device. The purpose is to test the performance of the terminal guided projectile and obtain the desired ground trace of scanning. Analysis of these flight tests confirmed the results of static wind tunnel tests at small angles of attack. System performance identification for large angles of attack. More scheduled flight tests have been scheduled, in which tests a full suite of instrumentation and thrust procedures will be selected to fully stimulate the issue of projectile dynamics.
