• S4062-PT (Fig. 12.99)
The S4062 was intended to be an improvement over the S4061. The major modification is a longer run of laminar flow designed into the S4062. But as the data shows, this design change has not lead to improved performance. Rather, the S4062 has higher drag owing to a larger laminar separation bubble. It is interesting to note that this problem is also predicted by the ISES code which was not available when the S4062 was designed.
