580例歼击机飞行员的基础+G_z耐力检查结果分析

Analysis of the relaxed +G_x tolerance records of 580 fighter pilots

目的分析歼击机飞行员的基础+G_z耐力检查结果。方法对580例歼击机飞行员的基础+G_z耐力分布、平均+G_z耐力、检查合格率,以及检查结果与年龄、飞行时间的关系进行了分析。基础+G_z耐力的检查在六三型载人离心机上进行,采用SPSS 10．0软件对试验数据进行统计学分析。结果该组飞行员的平均基础+G_z耐力为4．26±0．43 G,离心机检查合格率为81．4%。27～31岁年龄组飞行员的合格人数最多,共184人;37～43岁年龄组飞行员的合格率最高,达90．5%。平均+G_z耐力、检查合格率与年龄及飞行时间具有相关性(P＜0．05)。结论以+4．25 G_z持续10 s(+G_z增长率1 G/s)作为基础+G_z耐力合格标准是合理的。通过增加监测飞行员用力情况的措施,可进一步完善检查方法。

Objective To investigate the relaxed ＋Gx tolerance records of fighter pilots tested on human centrifuge. Methods The ＋Gx tolerance distribution, mean ＋Gx tolerance, qualified rate and the correlation between age, flying hour and ＋Gx tolerance of 580 fighter pilots were analyzed. The relaxed ＋Gx tolerance examination was performed on human centrifuge. The data were analysed by the software of SPSS 10. 0. Results The mean ＋Gx tolerance and qualified rate were 4.26 ±0.43 G and 81.4%. The maximal qualified number and rate were found in 27～ 31 years group （184） and 37～43 years group （90.5%） respectively. The mean ＋Gx tolerance, qualified rate were significantly related to the age and flying hours （P〈0.05）. Conclusions It is reasonable to screen aircraft pilots by the relaxed ＋Gx tolerance standard which is to complete a rapid onset （1 G/s） ＋4. 25 G, 10 s centrifuge profile successfully. The current ＋Gx tolerance examination shuld be improved by monitoring the straining extent of pilots being tested.
