摘要
超临界自然层流翼型具有很好的应用前景。西北工业大学翼型研究中心设计的我国第一个超临界自然层流翼型 NPU-L72513在 CARDC 高速所的跨声速风洞进行了试验,证明超临界自然层流翼型 NPU-L72513具有优良气动特性,其设计是成功的。同时说明我国已初步具有自行设计超临界自然层流翼型和进行相应风洞试验的能力。
The supercritical natural laminar airfoil is born of thesupercritical airfoil and the laminar reduction technology.It has goodaerodynamic characteristics and will be further used in the aircraftmanufacture in the future.The transonic wind tunnel test method isalso needed to be improved from the general method.In this paper theresult and the analysis of the transonic wind tunnel test of the super-critical natural laminar airfoil NPU-L72513 in China,by the Center forthe Airfoil Research of Northwest Polytechnical University,is intro-duced.From the result and the analysis,it can be found that the airfoilhas good aerodynamic characteristics,and the design is successful.
