A comparison of lift force coefficients again shows Grace's results to be somewhat lower . The maximum lift phase angle shows considerable scatter . The maximum lift most frequently occurs at maximum velocity but can also be seen to ...

As for profile V , the negative lift can be explained by the position of the stagnation point and the angle of attack of the approaching flow . This angle can in Fig . 6 be found to be around 10-15 degrees , which fits well with the ...
