Abstract

Abstract

To improve the safety of the vehicle underwater recovery, the designed shutdown depth of the vehicle shall match the inflation time of the floating device. At present, the research results on underwater inflation time of vehicle floating device are not universal, and they are not suitable for different structural forms of floatation collar and different structural forms of inflation pipelines. Because the composition of the inflation pipeline of the floating device is not suitable for using the traditional method to test the pipeline flow coefficient, the pipeline flow coefficient test method is redesigned to measure the flow coefficient of the inflation pipeline, and then the inflation time of the floating device is calculated by using the inflation time calculation model under the condition of fixed product adiabatic deflation. The calculation results are in good agreement with the test data, It can provide reference for navigation depth design and shutdown process.
