This study is devoted to the investigation of optimal conditions for flow-induced autorotation of a hinged cylinder in a direction perpendicular to the flow in a water tunnel. Previous studies of h...

Atmospheric entry aerodynamic decelerators which also provide thermal protection do not scale well for smaller payloads (e.g. CubeSat) or where the planets atmosphere is significantly less dense than the Earth's (e.g. Mars entry). Both cases require

In some specific conditions, a solid body exposed to a fluid flow rotates continuously in spite of absence of external energy, which is known as autorotation. In explaining autorotation dynamics, vortex shedding and stagnation pressure have been ment

As samara seeds fall from trees, they enter into auto-rotation. In this way they maximize dispersal distances (Green, Am J Bot 169:1218–1224, 1998, [2]). In this study, we present direct numerical simulations of the autorotation of a model samara a

This paper investigates the suitability of different aircraft configurations for use as an automated air transportation system. The underlying unmanned cargo aircraft, carrying a payload of about 1 ton and operating in the lower air space, is further
