A method and system for model test research of a double-impeller floating fan

Abstract

The application provides a double-impeller floating fan model test research method and system, including: establishing a numerical wind field system and a numerical fan according to test conditions, calculating the aerodynamic load of the fan under the test working condition at the prototype scale, and obtaining an aerodynamic load input file; determining the range, structure form, weight and installation mode of a multi-channel aerodynamic load reproducer according to the aerodynamic load input file; determining a scale reduction ratio according to the fan parameters at the full scale, determining a physical sea test environment model according to the scale reduction ratio, and installing sensors and a non-contact optical dynamic capture system in the test environment; building a communication and control system according to the test environment model, which is used for communication and control between the numerical fan and the physical sea test environment model. The application replaces the physical double-impeller model and the wind making system with the multi-channel aerodynamic load reproducer, and builds an aerodynamic load correction system, which can capture platform motion information in real time and correct the aerodynamic load following the platform motion in real time.
