摘要: 为研究武装直升机对小口径杀爆(HE)弹的防护策略,建立了某型武装直升机在小口径杀爆弹打击下的易损性模型,计算了典型受攻击方向的武装直升机易损面积,并将武装直升机底面划分为不同区域,计算了各区域的防护效率。计算表明,武装直升机最易损方向为其右后下方,此方向的易损面积为6.97 m2,结合武装直升机的外形特征,得出底面和侧面应当优先防护。对于武装直升机底面,前后燃油箱所在的2个区域的防护效率均达到50%以上,在布置装甲重量有限的条件下可优先防护该区域。另外,在主机身与机尾舱之间增加隔板可阻挡弹丸爆炸后横向飞散的破片,与直接防护武装直升机尾部相比,其防护效率由2.93%提高至11.07%。

Abstract: In order to study the defense strategy for gunship against small caliber High-Explosive(HE) munition, the vulnerability model of gunship under the attack of small caliber HE munition was established and the vulnerable area of gunship in typical strike directions was calculated. The bottom of the gunship was divided into several regions and the defense effectiveness of these regions was calculated.According to the calculation results, the vulnerable area of gunship attacked from the lower-right back direction is 6.97 m2, which exhibits the highest vulnerability. Considering the shape of the gunship, its bottom and sides need to be defended on the top of priority. The defense effectiveness of the two regions that contain front and back fuel tanks is higher than 50%, which means that these regions should be priorly defended if the mass of armor is limited. Adding the clapboard between the mainbody and the tail of the gunship can prevent the fragments spreading in the lateral direction after explosion of projectile, which leads to the defense effectiveness improving from 2.93% to 11.07%, compared with direct defense of the tail region of gunship.

Key words: gunship, small caliber High-Explosive(HE) munition, vulnerability, defense strategy, damage assessment
