High Performance Reefable Wingsail Rig Design and Pre-deployment Trial

海洋翼帆公司、IDPortal工程公司和南安普敦大学正在合作改进新型可reefable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，从而在所有标题下显著减少碳排放。该项目被视为智能、可礁翼帆大规模商用部署的重要垫脚石。翼帆的设计将考虑到实际的游艇设计和工作船只的可扩展性。该项目的总体目标是展示新型翼帆，并预测其部署后的温室气体减排效果。带有襟翼的翼帆在起飞和降落时类似于飞机机翼上的襟翼，可以产生比同等大小的传统帆更大的动力，并且更接近风。这允许使用较小的帆和较低的桅杆高度，使其较少妨碍港口的商业装卸作业，并增强航行性能。目前的高性能刚性框架翼帆带有整体桅杆，每次使用时都需要起重机来装配/吊装船，因为翼帆不能长时间安全放置。这个项目是基于一个创新的专利系统，通过使用高性能的薄膜翼帆覆盖材料，同时允许它被冷冻或卷起/装载，从而提高帆船平台的性能，从而促进其在必须能够应对恶劣天气的远洋船舶上的使用。这是通过使用基于刚性横向框架的翼帆来实现的，翼帆可以伸直，允许两侧的帆覆盖被剥落或卷起。这使得刚性翼帆的性能优势与基于薄膜的帆布/覆盖物保持一致，同时允许帆覆盖物在保留桅杆的同时被收进或完全移除。该项目利用计算流体动力学技术来改进开槽翼帆原型机的空气动力学性能，以及复合翼帆桅杆和框架的结构设计，并从早期的概念验证原型机中吸取经验教训，开发实用且强大的翼帆提升和控制系统。

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.
