| Abstract: | In order to improve the development efficiency of underwater vehicles, the hydraulic test - bed of underwater heat engine propeller system was designed. The schematics of data acquisition assembly in the under water thermodynamic propeller system test rig was described. The pressure and flow rate were tested. Signal reliability was improved by using a low - pass filter to silence background noise. The experiment validates the reliability and practicability of the system. |
