| 中文摘要: |
| 研究了氧平衡及爆炸下极限条件对燃料空气炸药（Fuel Air Explosive，FAE）云雾爆轰半径的影响。由固相FAE燃料的氧平衡及爆炸下极限条件，导出一次引爆型固相FAE云雾爆轰半径计算公式，并从理论上给出了FAE云雾爆轰半径的范围。通过对FAE爆炸场超压的测量及对FAE爆炸过程高速摄像分幅照片的定量分析，得到一次引爆型固相FAE的云雾爆轰半径，并将其与计算的云雾爆轰半径进行了对比，计算的云雾爆轰半径与试验值是一致的。研究结果表明，FAE燃料负氧越多，对应的云雾爆轰半径值越大；燃料爆炸下极限值越小， |

| Effect of oxygen balance and explosion limit inferior to cloud detonation radius of solid single event FAE was studied. Based on the law of oxygen balance and explosion limit inferior, formulas of cloud detonation radius of FAE were deduced, and the possible range of cloud detonation radius was also theoretically given. Cloud detonation radius was also obtained by measuring the overpressure in FAE blast field together with quantitatively analyzing photos of blasting fireball taken by high-speed frame photography and compared with calculated value. Results indicate that the calculated radius is in accord with the experiment data. It can be concluded that the scarcer oxygen in FAE fuel is, the bigger the cloud detonation radius is；secondly, cloud detonation radius increases along with the decrease of explosion limit inferior, thirdly, cloud detonation radius of solid FAE has never exceeded the calculating value under explosion limit inferior. High efficiency fuel of FAE may be selected by oxygen balance and explosion limit inferior, and this way of enhancing FAE power is proposed. |
