High Performance Reefable Wingsail Rig Design and Pre-deployment Trial

Oceanic Wingsails、IDPortal Engineering和南安普顿大学正在合作完善新型可收帆高性能翼帆的空气动力学、结构和复合材料设计，以最大限度地提高动力输送，从而在所有航向上显著减少碳排放。该项目被视为一个关键的垫脚石，以大规模部署的智能，reefable翼帆的商业部署。翼帆的设计将考虑到实际的游艇设计和工作船的可扩展性。该项目的总体目标是展示新的翼帆沿着以及预测的温室气体减排量。翼帆与襟翼类似于客机机翼起飞和降落时使用的襟翼，可以产生比类似尺寸的传统帆更大的驱动力，并且更接近风。这允许使用具有较低桅杆高度的较小帆，使其对港口商业装卸作业的阻碍较小，并提高航行性能。目前具有整体桅杆的高性能刚性框架翼帆需要起重机来装配/由于翼帆不能安全地长时间保持在上面，因此每次使用时都要对船进行调试。该项目基于一种创新的专利系统，用于提高性能本发明的目的是通过能够使用高性能膜基翼帆覆盖材料，同时允许翼帆完全收起或卷起/收起，从而促进其在必须能够科普恶劣天气的远洋船舶上的使用，来提高帆船的性能。这是通过使用基于刚性横向框架的翼帆来实现的，所述刚性横向框架可以伸直以允许覆盖在任何一侧的帆被剥落或卷起。这使得具有膜基帆布的刚性翼帆的性能优势。该项目利用计算流体动力学来改善原型开缝翼帆的空气动力学性能和复合材料翼帆桅杆和框架的结构设计，并应用早期的经验教训，概念验证原型，以开发实用和强大的系统，用于提升和控制翼帆。

Oceanic Wingsails, IDPortal Engineering and Southampton University are collaborating to refine the aerodynamic, structural and composite design of novel reefable high performance wingsail to maximise power delivery in order to poduce significant carbon reductions across all headings. This project is seen as a crucial stepping stone to an at scale deployment of a smart, reefable wingsail for commercial deployment. The wingsail will be designed taking into account practical yacht design and working vessel scalability. The overall goal of the project is then to demonstrate the novel wingsail along with predicted GHG emission reductions as deployed.Wingsails with flaps analogous to those used by an airliner wing when taking off and landing can generate significantly more drive than a conventional sail of similar size as well as sailing closer to the wind. This allows the use of a smaller sail with a lower mast height, making it less obstructive to commercial loading/unloading operations in port as well as enhanced sailing performance.Current high performance rigid framed wingsails with integral masts need a crane to rig/derig the boat every time it is used as the wingsail cannot be safely left up for long.This project is based on an innovative and patented system for enhancing the performance of sailing rigs by enabling a high performance film based wingsail covering material to be utilised while allowing it to be reefed or furled/stowed completely, facilitating its use on oceangoing vessels which have to be able to cope with severe weather. This is achieved by using wingsails based on rigid transverse frames which can straighten out to allow the sail covering on either side to be flaked or furled. This allows the performance advantages of a rigid wing sail with film based sailcloth/covering to be retained while allowing the sail covering film to be reefed or removed altogether while leaving the mast in place.This project uses Computational Fluid Dynamics to improve the aerodynamic performance of a prototype slotted wingsail and the structural design of the composite wingsail mast and framing as well as applying the lessons learned from an earlier proof-of-concept prototype to develop practical and robust systems for hoisting and controlling the wingsail.
