The present purpose is to reveal the mechanism of a flying pipe from an aerodynamic point of view. At first, we conduct field observations of a flying pipe using a pair of high-speed video cameras, together with three-dimensional motion analyses. In addition, we conduct numerical analyses by a finite difference method based on the MAC scheme. As a...

To reveal the mechanism of a flying pipe, we conduct field observations of the flying pipe in rotation using a pair of high-speed video cameras, together with 3D motion analyses based on their recorded images. Moreover, we attempt numerical analyses. As a result, the field observations show the statics of flying-pipe aerodynamics for both commercia...

The present aim is to reveal the flow past a rotating pipe which is immersed parallel to the mainstream. At first, we conduct field observations of a flying pipe in rotation using a pair of high-speed video cameras, together with motion analyses based on their recorded images, which quantitatively show paths and the change of kinetic parameter such...

... This work aims to resolve this issue by using a dedicated launch mechanism for better control on the initial flight parameters. The X-Zylo itself was also subject of former investigations [4,5], but in less depth than in the present study. Future applications could involve the optimization of such toys as well as potential insights in annular airfoil technology experimentally used for coleopters in the past. ...
