Human Factors Evaluation of Submarine Escape. V. Disconnect Time with Four Combinations of the Schrader Quick Disconnect Air Fitting
Abstract
Utilizing a simulated escape and survival equipment appliance, four arrangement of the standard Schrader quick-disconnect air fitting and two escape trunk hose positions, fixed and floating, were evaluated with respect to speed and reliability of disconnect in a dry environment. The results indicated that the most desirable arrangement of the Schrader connector is one in which the female part of the connector is attached at a 90 degree angle with respect to the charging hose of the EASE, while the male connector is attached at a 0 degree angle with respect to the air hose in the escape trunk. Hose position was not significant for this arrangement. Since the connector is intended to be used in a wet environment, and this research was performed in a dry environment, it is recommended that the study be repeated in a wet environment before final conclusions are drawn.
