| Abstract | ABSTRACT OF THE DISCLOSURE The present disclosure discloses a method for jointly measuring aerodynamic lift and aerodynamic drag coefficients, which comprises the following steps: Step 100: establishing a model device for a moving model experiment; Step 200: providing a data acquiring equipment on the model device and weighing the weight of the whole experimental model formed by the model device and the data acquiring module; Step 300: completing experiments in different speed regions with the experimental model on the moving model rig, and obtaining multiple effective test values; Step 400: based on multiple acceleration data and vertical force data of the experimental model obtained by the data acquiring equipment, sequentially obtaining the aerodynamic lift coefficient and the aerodynamic drag coefficient of the experimental model in the moving model test through data processing and calculation. The moving model test carried out in the present disclosure can not only realize the joint measurement of aerodynamic lift and aerodynamic drag coefficients, but also complete many experiments which cannot be completed by a wind tunnel test. - 1/1 DRAWINGS 100 Establishing a model device for moving model test 200 Proving a data acquiring equipment on the model 400 citothe model on a moving model rig and obtaining multiple effective test data 1z 400 Based on multiple acceleration data and vertical force data from the moving model test, sequentially obtaining the aerodynamic lift coefficient and aerodynamic drag coefficient of the model in moving model test through data processandcalculation FIG. 1 |
