摘要

作为船舶辅助推进风筝的设计和运行的一部分，有必要能够快速估计沿各种轨迹的气动力。为此，建立了基于普朗特抬升线的三维非线性模型。它允许这些快速计算翅膀与任何法律的二面角，扭转和横扫角，沿跨度，并为一般飞行运动学考虑到平移速度和旋转速率。该模型已通过与用Navier-Stokes求解器进行的三维模拟的比较得到验证。它给出了令人满意的发生率和侧滑结果，预测升力的差距约为4%。特别注意对所提供的数值结果的精度的估计。

Benchmarking of a 3D non-linear lifting line method against 3D RANSE simulations

As a part of the design and operation of kites as auxiliary propulsion of vessels, it is necessary to be able to quickly estimate the aerodynamic efforts along various trajectories. A 3D non-linear model based on the lifting line of Prandtl has been developed for this purpose. It allows these rapid calculations for wings with any laws for the dihedral angle, the twist, and the sweep angle, along the span, and for a general flight kinematic taking into account translation velocities and rotation rates. This model has been verified by comparison with 3D simulations performed with a Navier-Stokes solver. It gives satisfactory results in incidence and sideslip, with gaps of about 4% for forecasts lift. Special attention has been paid to the estimation of the accuracy of the provided numerical results.

期刊介绍： La Houille Blanche, revue internationale de l ''eau/International Water Journal, is the only almost all French-written journal of Water science. It promotes the dissemination of research and innovative practices in the field of water, as a key resource for everyday use for human needs, agriculture, energy and transport, and hydraulic public works. This includes environmental and risk assessment and management issues related to hydrology, meteorology, flood, low flows and drought, as well as issues in the field of fluid mechanics, hydraulics machinery, multiphase flows, microfluidics... La Houille Blanche, International Water Journal, is cited by Science Citation Index Expanded of Institute for Scientific Information (I.S.I) in USA, and by CNRS in France; since 1902, the journal publishes high-standard relevant peer-reviewed research papers. La Houille Blanche also provides more general information and recent news about the water world, and the SHF association and its members life: scientific events, book review, R & D advancements, … Six issues per year. Thematical journal for original articles and reviews mostly in French.
