The Naval Air Development Center's Human Centrifuge was used to assess the effects of repeated exposures to a simulated Air Combat Maneuvering (ACM) environment on various measures of physiological function and psychomotor performance. The environment consisted of a realistic ACM profile that included associated noise, high speed/stall buffet conditions, and increased intra-cockpit temperatures. The effects of varying the subject's seatback angle, as a function of the environment, was also measured. Analysis of the various physiological and performance data revealed the following: 1) heart rate was negatively correlated with tracking accuracy under the combined stress conditions of this study, 2) test conditions that included acceleration and buffet resulted in a significant decrement in tracking accuracy, 3) the addition of increased intra-cocpit temperatures, when combined with acceleration and/or buffet, produced a significant decrease in tracking accuracy, 4) increasing the seatback angle from the vertical partially ameliorated the effects of the other stressors. Details of these findings, as well as results of various biochemical analyses, are discussed.
海军航空发展中心的人体离心机被用于评估反复暴露于模拟空战机动(ACM)环境对各种生理功能指标和心理运动性能的影响。该环境由逼真的ACM剖面组成,包括相关噪音、高速/失速抖振条件以及驾驶舱内温度升高。还测量了根据环境改变受试者座椅靠背角度的影响。对各种生理和性能数据的分析揭示了以下几点:1)在本研究的综合应激条件下,心率与跟踪精度呈负相关;2)包括加速度和抖振的测试条件导致跟踪精度显著下降;3)当驾驶舱内温度升高与加速度和/或抖振相结合时,跟踪精度显著降低;4)将座椅靠背角度从垂直方向增加可部分减轻其他应激源的影响。讨论了这些发现的细节以及各种生化分析的结果。
