WND TUNNEL TESTS OF THE UAG 92-170/SF SLOTTED FLAPPED WING SECTION
Keywords:Aerodynamics, Structures, Design
AbstractWind tunnel tests have been carried out to determine the characteristics of the UAG92770/SF slotted flap wing section for use on variable geometry sailplanes. This wing section depends on a camber flap to obtain a wide range of operational lift coefficient, and would be mostly operated with the camber flap deflected up. Flap extended lift - drag characteristics of this wing section are comparable to slotted flapped version of the FX 67 VC 770/36 wing section used on the Sigma variable geometry sailplane. Drag coefficient for this wing section lies between that geometry sailplane using a slotted flapped wing section.
