Aero-Hydrodynamics of an RS:X Olympic Racing Sailboard
نویسنده
چکیده
The RS:X Olympic sailboard is an all-round board designed to be raced in 4 to 25 knots of wind, and is an example of the current state-of-the-art in sailboard design. This board has been chosen as the specific example for an overview of sailboard aero-hydrodynamics. The current article brings together previous research on sailboard sail and fin lift, and applies it to the case of the RS:X sailboard. Measured sail camber and twist, as well as mast stiffness and deflection, are described for realistic upwind racing settings. The three-dimensional force and moment balance of an RS:X sailing upwind is investigated, in order to determine the limits on righting moment, sail lift and fin lift for different wind strengths. Finally a planing analysis is performed on the RS:X sailboard to calculate trim, wetted length and resistance.

Analysis of flow around an RS : X Racing 66 windsurfing fin
The behaviour of fluid flowing past a RS:X Racing 66 windsurfing fin at different angles of attack was studied both computationally and experimentally. This was achieved by creating a three dimensional computational model of the fin, which was both used to produce a physical model for experimental testing, and as the basis for analysis using the fluid analysis program, OpenFOAM. The experimenta...

From an international perspective, Polynesian outrigger canoe racing is a relatively new sport compared with other paddle sports that have become Olympic events, such as canoeing and kayaking. Performance is more highly tuned in highly competitive Olympic sports, which receive more attention from sports science researchers [1-3]. A Google Scholar search, minus citations and patents, indicated r...

This contribution reports on the potential and limits of a meshless Lagrangian technique, called Smoothed Particle Hydrodynamics (SPH), as a method for acoustic simulation. The established techniques for acoustic simulation, such as the Boundary Element Method (BEM), Finite Differences Method (FD), and Finite Element Method (FEM), draw on mesh-based numerical solution techniques. In spite of st...
متن کاملAn Assessment of Semi-Discrete Central Schemes for Hyperbolic Conservation Laws
High-resolution finite volume methods for solving systems of conservation laws have been widely embraced in research areas ranging from astrophysics to geophysics and aero-thermodynamics. These methods are typically at least second-order accurate in space and time, deliver non-oscillatory solutions in the presence of near discontinuities, e.g., shocks, and introduce minimal dispersive and diffu...
