Project Overview – Ultra-Green Airliner Concept (A-17 Zephr) A-17 Zephyr project envisions a next-generation airliner concept, comparable in size and capacity to the Boeing 737, designed for a future where fossil fuel prices are prohibitively high and environmental sustainability is a global imperative. Targeted for entry into service between 2030 and 2035, the A-17 integrates advanced, forward-looking technologies to significantly reduce emissions and improve operational efficiency. Key innovations include: Hybrid Laminar Flow Control (HLFC), Aft-mounted Propulsor for Boundary Layer Ingestion (BLI), High-bypass ratio geared turbofan engines, Power-by-wire actuation systems, Electric taxiing capabilities, High Aspect Ratio wing with foldable configuration. A defining feature of the A-17 is its ultra-high aspect ratio wing, which substantially reduces induced drag. In combination with natural laminar flow over the wing surface, this configuration dramatically cuts skin friction drag, leading to improved fuel efficiency and lower environmental impact. In my role as an Aircraft Structural Design Engineer, I was primarily responsible for overseeing the high-load-bearing structures within the forward fuselage. My key tasks included, designing and reinforcing the forward fuselage structure, integrating and analysing the nose landing gear attachment points, conducting initial load analysis, including symmetric fuselage loading calculations. Also, as the Risk manager of the structures team I was responsible of oversee the project risks and discuss with other project managers to come up with mitigation actions. The tasks involves of Risk Identification, Risk Assessment, Risk Mitigation, Compliance & Regulations, Data Analysis & Reporting, Cross-functional Collaboration, Incident Response & Investigations, Continuous Improvement.
