Integrated Protection Capability Afforded by a New Type Capstan Anti G Equipment and Anti G Straining Maneuver.

目的对新型侧管式抗荷装备与抗荷动作的综合防护性能进行研究， 探讨采用二者联合的方案对８ Ｇ１０ ｓ（增长率为２ Ｇ／ｓ）高Ｇ 进行防护的可行性。方法在离心机上， ＋ Ｇｚ 增长率为２ Ｇ／ｓ， 先测定９ 名飞行学员的基础＋ Ｇｚ 耐力， 其中５ 名飞行学员采用新型侧管式抗荷服（ＮＫＨ） ＋ 新型抗调器（ＮＫＴ）＋ Ｌ１ 动作（Ｌ１）、另４ 名飞行学员采用新型侧管式代偿服（ＮＤＣ） ＋ ＮＫＴ＋ Ｌ１，测定出其最大＋ Ｇｚ 耐力。结果５ 名飞行学员采用ＮＫＨ＋ ＮＫＴ＋ Ｌ１ 时的最大＋ Ｇｚ 耐力为８．８０±０ ．２７ Ｇ， 比基础＋ Ｇｚ 耐力高出４．６０±０．４２ Ｇ（Ｐ＜０．０１） ；４ 名飞行学员采用ＮＤＣ＋ ＮＫＴ＋ Ｌ１ 时的最大＋ Ｇｚ 耐力为８．７５±０ ．５０ Ｇ， 比基础＋ Ｇｚ 耐力高出４．５０±０．４６ Ｇ（ Ｐ＜０ ．０１） 。结论飞行员采用新型侧管式抗荷装备与抗荷动作能够对８ Ｇ１０ ｓ（ 增长率为２ Ｇ／ｓ） 的高Ｇ 进行有效防护。

Objective To investigate the integrated protection capability afforded by a new type capstan anti G equipment and anti G straining maneuver, as a result we discussed the feasibility of protection for 8G 10s (rapid onset runs at 2G/s) acceleration using a associated precept with the above both anti G measures. Method This study was accomplished using the human centrifuge with rapid onset at 2G/s. First, we determined the relaxed +Gz tolerance of nine male aviation students, and then determined theirs most +Gz tolerance while thereinto the five aviation students using a new type capstan anti G suit (NKH) + a new type anti G valve (NKT)+L 1 anti-G straining maneuver (L 1) and the other four aviation students using a new type capstan counterpressure suit (NDC)+ the new type anti G valve (NKT)+L 1. Result The most +Gz tolerance of five students was 8.80±0.27 G while using NKH+NKT+L 1 and was higher than their relaxed +Gz tolerance at 4.60±0.42 G (P<0.01); and that the most +Gz tolerance of four students was 8.75±0.50 G while using NDC+NKT+L 1 and was higher than their relaxed +Gz tolerance at 4.50±0.46 G (P<0.01). Conclusion Pilot will be capable against the 8 G 10 s (rapid onset runs at 2 G/s) effectively using the new type capstan anti ±G equipment and anti ±G straining maneuver, and the provided precept has availability.
