摘要: 文章自主研發(fā)了一種新型的氣動(dòng)力彈丸與彈托分離技術(shù)。在北京衛(wèi)星環(huán)境工程研究所的φ18 mm二級(jí)輕氣炮上應(yīng)用該技術(shù)在3~7 km/s的速度內(nèi)可以成功分離直徑在3~10 mm的彈丸，彈托分離非常干凈，分離成功率達(dá)100%。對(duì)比分析顯示，該技術(shù)分離效果優(yōu)于目前公開報(bào)道的其它技術(shù)。Abstract: A new projectile/sabot aerodynamic separating technique in hypervelocity impact experiment is developed. By using this technique, the Al spheres with diameters of 3 mm to 10 mm are separated with sabot successfully in the velocity ranges of 3～7 km/s, on the two-stage-light-gas gun with 18 mm caliber in the Beijing Institute of Spacecraft Environment Engineering. This technique is favorably compared with the existing sabot separating results.
