Abstract
The wind tunnel test and numerical calculation of ventral support interference for a rigid airship model are conducted in this paper.In the wind tunnel test,the one-point ventral support system is used for sustaining the airship model,the aerodynamic data are acquired,and the support interference values are obtained by the two-step mirror method.However,in the test the secondary interference between the main support and the mirror support can not be deducted, which would bring some errors to the support interference correction.So the numerical method is introduced to calculate the aerodynamic properties in the situations of airship model only,model with support,reverse model with support,and reverse model with main support and mirror sup-port,respectively.Based on the work,the net support interference and the secondary interfer-ence are acquired.By comparing the test and numerical results,some conclusions are drawn as follows:the test and numerical results are consistent about the way in which the support affects the airship aerodynamic properties,but there are obvious differences in the interference values, which shows that the secondary interference can not be ignored and must be considered in the process of support interference correction for the airship wind tunnel test.关键词
