Aerodynamics of a double-element wing in ground effect [PDF]
, 2003 A study was performed of a cambered, double-element, high-lift wing operating in ground effect. The effect of ground proximity and flap setting has been quantified in terms of aerodynamic performance and off-surface flowfield characteristics ...

The effect of military load carriage on ground reaction forces [PDF]
, 2007 Load carriage is an inevitable part of military life both during training and operations. Loads carried are frequently as high as 60% bodyweight, and this increases injury risk. In the military, load is carried in a backpack (also referred to as a Bergen)

Wake behind a Compound Wing in Ground Effect
Journal of Marine Science and Engineering, 2020 Flow structure is a crucial point for the conceptual design of Wing-in-Ground effect (WIG) crafts. In this study, pressure distributions around a compound wing, velocity and the turbulent intensity distribution in the wake area after trailing of the wing,

Aerodynamic measurement of a track runner using a wind-tunnel moving-belt system
Nihon Kikai Gakkai ronbunshu, 2014 Concerning most of track-and-field athletics such as the marathon, it is important to clarify the flow around track runners and to evaluate their air resistances (or wind resistances, drags).

Ground spider communities in experimentally disturbed Mediterranean woodland habitats [PDF]
, 2011 The protected Mediterranean woodland habitats in Israel are undergoing tree encroachment, resulting in loss of open patches with herbaceous vegetation. We suggested that this process results in a ground spider community dominated by shade-loving species.
