Performance Enhancement by Wing Sweep for High-Speed Dynamic Soaring
Autor: Gottfried Sachs, Benedikt Grüter, Haichao Hong
Publikováno v: Aerospace, Vol 8, Iss 8, p 229 (2021)
Dynamic soaring is a flight mode that uniquely enables high speeds without an engine. This is possible in a horizontal shear wind that comprises a thin layer and a large wind speed. It is shown that the speeds reachable by modern gliders approach the

Smooth free-cycle dynamic soaring in unspecified shear wind via quadratic programming
Autor: Florian Holzapfel, Haichao Hong, Patrick Piprek, Benedikt Grüter
Publikováno v: Chinese Journal of Aeronautics. 35:19-29
Harvesting wind energy is promising for extending long-endurance flights, which can be greatly facilitated by a flight technique called dynamic soaring. The presented study is concerned with generating model-based trajectories with smooth control his

Trajectory Optimization and Analytic Solutions for High-Speed Dynamic Soaring
Autor: Gottfried Sachs, Benedikt Grüter
Publikováno v: Aerospace, Vol 7, Iss 4, p 47 (2020)
Dynamic soaring is a non-powered flight mode that enables extremely high speeds by extracting energy from thin shear wind layers. Trajectory optimization is applied to construct solutions of the maximum speed achievable with dynamic soaring and to de

Ski Jumping Trajectory Reconstruction Using Wearable Sensors via Extended Rauch-Tung-Striebel Smoother with State Constraints
Autor: Xiang Fang, Benedikt Grüter, Patrick Piprek, Veronica Bessone, Johannes Petrat, Florian Holzapfel
Publikováno v: Sensors, Vol 20, Iss 7, p 1995 (2020)
To satisfy an increasing demand to reconstruct an athlete’s motion for performance analysis, this paper proposes a new method for reconstructing the position and velocity in the context of ski jumping trajectories. Therefore, state-of-the-art weara

High-Speed Flight Without an Engine: A Unique Performance Capability Enabled by Dynamic Soaring
Autor: Gottfried Sachs, Benedikt Grüter
Publikováno v: Journal of Guidance, Control, and Dynamics. 44:812-824
Dynamic soaring is an engineless flight mode that is feasible by extracting energy from horizontally blowing shear wind. There is a possibility of extremely high speeds in wind scenarios where a th...
