Abstract: Firstly,The ballistic property of terminal sensing ammunition is studied. The reason of the scan interval in the stable scan section is analyzed. Finally, analyze four questions in detail which are computing technology of scanning interval, evaluating shooting efficiency, choosing the individual static or mobile target. According to the analysis above, the data of terminal sensing ammunition firing the he individual static or mobile target is reached. The fighting efficiency of terminal sensing ammunition is strengthened.
Key words: The terminal sensing ammunition; Scan interval; Firing result
末端敏感彈藥(簡(jiǎn)稱(chēng)末敏彈)是一種既適用于間瞄射擊、又能對(duì)遠(yuǎn)距離裝甲目標(biāo)實(shí)施有效攻擊的新型彈藥。
1 末敏彈彈道特性
末敏彈的彈道可分為母彈飛行段、拋射段、拉直段、充氣段、減速減旋段與穩(wěn)態(tài)掃描段。其飛行彈道如圖1所示。
母彈飛行段的彈道與普通榴彈的彈道基本相同。
拋射段指末敏彈離開(kāi)母彈到末敏彈的降落傘開(kāi)始拉出的過(guò)程。該段時(shí)間雖短,但對(duì)末敏彈以后幾個(gè)階段的運(yùn)動(dòng)影響較大,它為拉直段運(yùn)動(dòng)提供初始條件。
拉直段是指從降落傘開(kāi)始拉出至伸直的過(guò)程。
充氣段是指降落傘全長(zhǎng)拉直至傘衣充滿空氣為止的過(guò)程。該段的工作過(guò)程是最重要也是最復(fù)雜的過(guò)程。
減速段與穩(wěn)態(tài)掃描段系指降落傘完全充滿空氣后,產(chǎn)生的空氣阻力使傘彈系統(tǒng)持續(xù)減速的階段。當(dāng)末敏彈系統(tǒng)在空氣阻力和系統(tǒng)阻尼的作用下,下降到一定高度后達(dá)到穩(wěn)定狀態(tài),即末敏彈下降速度穩(wěn)定,末敏彈繞垂直軸的轉(zhuǎn)速穩(wěn)定。
