The Chinese airfoil genealogy and database, led to construct by Northwestern Polytechnical University headquartered in Xi’an, Shaanxi province in Northwest China, was released on Oct 16.

The press conference for Chinese airfoil genealogy and database was held in Xi'an on October 16.

This historic release marks the debut of China's aircraft wing profile genealogy, a development of immense strategic importance. It accelerates the establishment of wing profile systems and databases with fully independent intellectual property rights in China. This initiative enhances the nation's capacity for independent innovation in aerodynamic layout design within the aviation sector. It also bolsters the sustainable growth of high-end aerospace equipment in China, laying a robust foundation for enhancing aircraft performance, industrial advancement, and the enduring progress of the national aerospace industry.

The airfoil, as the cornerstone of an aircraft, profoundly influences aerodynamic efficiency, flight stability, and holds a pivotal role in aerodynamic theory and aircraft design.

During the press conference, Professor Gao Zhenghong, the project leader of the Chinese Airfoil Genealogy, presented the remarkable accomplishments of the Airfoil Genealogy project. The Advanced Airfoil Database incorporates tailor-made specialized airfoil genealogies tailored to the design requirements of 8 advanced aircraft types. This initiative has established China's premier independent high-performance airfoil genealogical system, encompassing over 1,000 airfoils from 6 series, alongside an industrial-grade database. This system facilitates multidisciplinary performance analysis of airfoils and custom airfoil design based on specific layout characteristics.

The research team behind this project has diligently addressed the nation's strategic imperatives. Over more than three decades of relentless research and development, they have formulated a suite of aircraft wing profiles with independent intellectual property rights. These profiles span a wide array of advanced wing configurations, bolstering the research and development of cutting-edge models and propelling advancements in China's aviation science and technology foundational research.

Experts and scholars praised the achievements of this project at the press conference.

Esteemed experts and scholars commended the project's achievements during the press conference.

Academician Zhang Weihong, Vice President of Northwestern Polytechnical University, delivered a speech on behalf of the university, hailing this milestone as a testament to the university's dedication to wing research over the past three decades.

Cao Baohong, vice president of the First Aircraft Institute of China Aviation Industry Corporation, emphasized the critical importance of systematically developing the Chinese airfoil genealogy for the nation's aerospace industry.

Academician Tang Changhong, Director of the Key Laboratory, underscored the significance of wing design as a cornerstone of aviation industry and aircraft design, emphasizing its role in supporting China's independent innovation in aviation technology and ensuring national economic security through mastery of key core technologies.

The unveiling of the Chinese Airfoil Genealogy and Database represents a landmark achievement by the National Key Laboratory of Aircraft Foundation Layout at Northwestern Polytechnical University. This accomplishment showcases the institution's commitment to core technology research and development in the aviation sector.

The establishment of the airfoil genealogy and database marks a pivotal moment for China, heralding independence from foreign airfoil databases in aerospace technology. This achievement not only safeguards national aviation and aerospace security but also elevates China's standing and influence in the global aviation and aerospace arena.

Moreover, the development of the airfoil genealogy promises to offer technical support across various sectors, including general aviation and unmanned aerial vehicles, fostering rapid advancements in these fields. This initiative provides vital technical backing for the growth of China's aerospace industry and lays a sturdy groundwork for continued innovation and progress in the nation's aerospace sector.
