• SD7084-PT (Fig. 12.146)

The SD7084 is a slightly modified SD7080. The primary differences are that the SD7084 is about 10% thicker, its lift range is greater, and the minimum drag is higher than the SD7080. The interesting result is that the two airfoils perform almost identically provided the SD7084 wing loading is about 10% greater. See Fig. 5.11.
