Research On Penetration Process Of Auti-Runway Warhead

The background, current situation and development of the modern anti-airportammunition is briefly introduced. The core contents of experience method, analyticalmethod and numerical method are presented and also applied to the projectile-targetpenetration field.The process of monobloc projectile penetrating concrete is simulated and analyzedby ANSYS/AUTODYN. The process and results of concrete damage in different formsof projectile head is compared and analyzed，the research in principle of concretedamage is discussed.The penetrating-detonating warhead penetrating airport is also simulated andanalyzed.On the basis of penetration simulation, the change laws of velocity, shellstrength and grain safety of penetrating-detonating warhead are compared and analyzed.Optimizing the best penetrating velocity and discussing the principle of runway damagewith the simulation results.That the explosive detonates in the runway is simulated,which is used to analyzethe influence of different detonating position on the explosive effect and make the bestdetonating position.By the simulation of penetrating-detonating destruction and penetrating-detonatingdestruction in high speed with delayed detonated time on runway.The results of damagein different conditions are compared and analyzed.The influence factories of second-damage effect for explosive in warhead on runway are summarized，that can providesome references for the design of penetrating-detonating warhead and for the researchof penetrating on runway.
