压力暴露后潜艇艇员快速上浮脱险可行性的初步理论推算

Preliminary theoretical calculation of the feasibility of fast buoyant ascent escape attempted by submariners following pressure exposure

目的探索潜艇艇员在艇内高压暴露一段时间后,进行快速上浮脱险的可行性,为实际脱险提供理论数据参考与支持。方法以组织半饱和理论基础,采用数学分析方法,计算艇员在不同情况下脱险出水时的氮张力值。结果当潜艇坐沉30 m内气压在8 m时,艇员高压暴露时间在235 min以内时,此时80 min组织的氮张力值换算相对饱和深度为6.99 m。结论当潜艇内气压高于0.07 MPa,且暴露时间在一定范围以内时,此时也可组织快速上浮脱险。

Objective To explore the feasibility of fast buoyant ascent escape by submariners after pressure exposure for a certain period of time, so as to provide theoretical data and support in actual submarine escape.Methods Based on the theory of the tissue half saturation and mathematical analysis, nitrogen tensions of the escapees at different situations were calculated when submarine escape was attempted.Results When the submarine sat at a depth of 30 meters, with an internal air pressure of 8 meters and high pressure exposure time within the range of 235 minutes, the tissue nitrogen tension at 80 minutes could be converted to the relative saturation depth of 6.99 meters.Conclusion When the internal pressure of the submarine is higher than 0.07 MPa and the exposure time is within a certain range, fast buoyant ascent escape could be attempted by submarines.
