The former Soviet Union was a leader in this field since it had developed several kinds of antiship missiles which obtained supersonic speed at minimum altitudes. To counter this kind of missile, many countries have been developing corresponding antimissiles. For the purpose of verifing the antimissile missile′s effectiveness in intercepting antiship missiles, a target-missile is needed. A target-missle is cheaper and can imitate the main characteristics of antiship missiles with supersonic speed at minimum altitude. In this paper, the control scheme of a target missile flying with supersonic speed at minimum altitude is studied. To counter the problem of hedgehopping over the sea, a control scheme utilizing a SINS+altimeter was proposed. In this scheme, both the quick response ability of altitude control and the anti-jamming problem were considered. A simulation experiment shows that when an integrated altitude control system is used, the anti-disturbance ability of the integrated altitude is good and the response speed of altitude control system can be dramatically improved.展开更多

In this study, three double-layer bulkheads with different interior sandwich structures were investigated, including X and hexagonal combined sandwich structure, cross-type honeycomb sandwich struc-ture and cell growth type honeycomb sandwich structure. The penetration processes of three different bulkhead structures were simulated by software ANSYS/LS-DYNA. The simulation shows that the double-layer bulkhead with cross-type honeycomb sandwich structure is the most suitable. Finally, the dynamic response characteristics of the cross-type sandwich bulkhead structure are analyzed.展开更多
