The ALFA Seal project (ALFA Seal - **A**dvanced **L**aminar **F**low sn**A**p-fit Seal) builds on previous UK government and industry funded projects aiming to make air travel more environmentally sustainable through the enablement of wing laminar flow, supporting the Government to committing to net zero greenhouse gas emissions by 2050\.Turbulent Wing design has evolved over the past 50 years introducing relatively small incremental changes to reduce drag and improve efficiency. To meet airlines requirements for reducing operating costs, and to respond to societal pressure for sustainable flight, a step change in technology is required.Laminar flow wing innovation enables such a step change, reducing fuel/energy burn, which in turn results in improved operating costs, improved profitability for the operators, and reduced environmental impact.In the future, component assembly will be increasingly smart and automated, and the novel laminar-flow-friendly ALFA Seal system champions this ambition.The ease of assembly of the innovative ALFA Seal system removes the need for sealant between joints (steps and gaps) balancing the conflicting requirements of tight aerodynamic tolerances, against cost-effective, easy-to-repair structures. In short, it solves and manages the stubborn legacy challenge of marrying laminar flow and mechanical fit.Moreover, as a replacement for traditional sealant, the ALFA Seal system would contribute to a ramp-up in aero-structure production rates, which will also be a differentiator with an upturn in aircraft demand.This project:* seeks to mature a novel laminar-flow-friendly assembly sealing solution for the key issues around space allocation and structural joining (steps and gaps) that meets aerodynamic tolerances, a ramp-up in production rates, and in-service operability requirements* contributes to laminar flow exploitation on future wings -- natural laminar flow for short-range aircraft and hybrid laminar flow for long-range* addresses priority areas within the ATI "Accelerating Ambition" (2019) Aerostructures Roadmap and aligns with the Future Flight Challenge of the Government's Industrial Strategy, the UK Jet Zero Council objectives, and the ATI's FlyZero initiative in accelerating improvements in environmental performance of future aircraft* exploits the City, University of London transonic wind tunnel as part of the National Wind Tunnel Facility (NWTF) infrastructure to obtain crucial test data that allows model validation and improved computational modelling, which will lead to a TRL4 seal product at the conclusion of the project

ALFA Seal项目（ALFA Seal - **A** advanced **L**aminar **F**low sn**A**p-fit Seal）建立在之前英国政府和行业资助的项目基础上，旨在通过实现机翼层流，支持政府承诺到2050年实现温室气体净零排放紊流机翼设计在过去50年中不断发展，引入了相对较小的增量变化，以减小阻力并提高效率。为了满足航空公司降低运营成本的要求，并应对可持续飞行的社会压力，需要技术上的一个台阶式变化。层流机翼创新实现了这种台阶式变化，减少了燃料/能量消耗，从而降低了运营成本，提高了运营商的盈利能力，并减少了对环境的影响。未来，部件装配将越来越智能化和自动化，创新的ALFA Seal系统易于组装，无需在接缝（台阶和间隙）之间使用密封剂，从而平衡了严格的空气动力学公差与经济高效、易于维修的结构之间的矛盾要求。简而言之，它解决并管理了层流和机械配合的顽固传统挑战。此外，作为传统密封剂的替代品，ALFA Seal系统将有助于提高航空结构的生产率，这也将成为飞机需求上升的差异化因素。该项目：* 针对空间分配和结构连接的关键问题，寻求成熟的新型层流友好型装配密封解决方案（台阶和间隙），满足空气动力学公差，生产率的斜坡上升，和使用中的可操作性要求 * 有助于在未来的机翼上开发层流--用于短程飞机的自然层流和用于远程飞机的混合层流 * 解决了ATI“加速的雄心”（2019）Aerostructures路线图，并与政府工业战略的未来飞行挑战、英国Jet Zero理事会目标以及ATI的FlyZero计划保持一致，以加速改善未来飞机的环境性能 * 利用城市，伦敦大学跨音速风洞，作为国家风洞设施（NWTF）的一部分基础设施，以获得关键的测试数据，允许模型验证和改进的计算建模，这将导致在项目结束时的TRL 4密封产品
