Apfsds armor piercing fin stabilized discarding sabot 尾翼穩(wěn)定脫殼穿甲彈
Picks the right weapon to use against the enemy . don ' t waste sabot rounds on infantry targets , for example 使用正確的武器攻擊敵軍,例如不要在步兵身上浪費穿甲彈。
Using fluent software , calculate the aerodynamic parameter of projectile and sabot . 3 ) . according to motion equations of sabot and parameter obtained above , calculate and analysis flying motion variety of sabot 3 )利用fluent軟件計算得出的彈托氣動力參數(shù),運用彈托的運動方程,計算并分析30mm脫殼穿甲彈的彈托飛行運動變化規(guī)徘。
For the rod penetrators used for 30mm naval gun , the structures , the ballistic performance , the penetration and their design are studied systematically . in the paper , the reasonable design of sabot and projectile core is presented and the influence of various factors on ballistic performance of rod penetrators is analyzed . additionally , the optimum design techniques in exterior ballistics for the small caliber fin - stabilized and sabot discarded penetrators are developed 本文對海30艦炮適用的桿式脫殼穿甲彈的結(jié)構(gòu)特性、彈道特性、穿甲威力及設(shè)計方法進(jìn)行了系統(tǒng)研究,提出了合理的彈芯結(jié)構(gòu)和彈托方案,研究了各種因素對桿式穿甲彈外彈道性能的影響,建立了一套小口徑尾翼穩(wěn)定脫殼穿甲彈外彈道優(yōu)化設(shè)計方法,并利用該方法在一定的戰(zhàn)術(shù)技術(shù)要求下對海30艦炮尾翼穩(wěn)定脫殼穿甲彈進(jìn)行了優(yōu)化設(shè)計,得到了優(yōu)化方案,研究結(jié)果對海30艦炮以及同類小口徑火炮桿式穿甲彈的設(shè)計有重要的指導(dǎo)意義。
Based on emperiment of " 30mm " armor piercing projectile ' s discarding sabot close to gun , study discarding sabot motion and process , and analysis discarding sabot characterstic , the possibility of disturb on sabot f ^ rm main gun under the disturb field of double gun . 2 ) 本論文研究工作的主要內(nèi)容有: 1 )從30mm脫殼彈膛口脫殼過程試驗,研究30mm脫殼彈出炮口后卡瓣及底托與彈芯的分離過程和分離運動;同時分析30mm脫殼彈的脫殼特性及在雙炮干擾場下彈托對主炮干擾的可能性問題。
