An investigation has been made to predict the effects of forebody and afterbody shapes on the aerodynamic characteristics of several projectile bodies at supersonic speeds using analytical methods combined with semi-empirical design curves. The considered projectile bodies had a length-to-diameter ...

This paper presents an aerodynamic modification scheme by using the class function/shape function transformation (CST) method to determine the optimal shape of the bluff body and hence improve the performance of the associated galloping-based wind energy harvester (WEH). The CST method, accompanying ...
" laughs Daniels. "We can't do anything about that. [But] we're not worried about it at the moment. Everyone's looking at it from a short angle and from below. As soon as we take it outside you'll see the sleekness and the aerodynamic shape and the whole bum thing will go ...
(22–24 in Perissodactyla and 21–30 in Afrotheria in ref.46). Within Afrotheria, 22 is also the most likely ancestral estimate for the ecologically diverse Paenungulata (Sirenia, Proboscidea and Hyracoidea) (23 in ref.49). A TL count of 19 is also probably plesiomorphic for ...

Aerodynamic and mechanical considerations are most likely to provide an understanding of these laws of shape, but an explanation has proved elusive so far. The detailed shape of a distribution can be reconstructed from the shape parameters by matching the moments of the observed distribution to ...
