China launches airfoil database to support innovation in aviation technology

China launched an airfoil design system and database on Wednesday to provide key technical support for independent innovation in the aviation sector.

The airfoil database was built by the National Key Laboratory of Aircraft Configuration Design in northwest China’s Xi’an City, which was jointly run by the Northwestern Polytechnical University and the First Aircraft Institute of Aviation Industry Corporation of China.

The database integrates a customized airfoil profile system designed for eight types of advanced aircraft, creating China's first such database for industrial applications.

"The research and development team, consisting of members of three generations, has devoted over 30 years of efforts to build up the theoretical foundation of airfoil design and combine it with model development, thus creating a comprehensive airfoil system in China from scratch. Now China has developed over 1,000 airfoils with complete independent intellectual property rights. The release of China's airfoil system marks a breakthrough in its independent development of basic research and design development in this field, which has great historical significance," said Tang Changhong, director of the National Key Laboratory of Aircraft Configuration Design, during the launch event.

As airfoil design is the foundation of aircraft design and development, experts said that the establishment of the airfoil database provides technical support for China's general aviation and drone sectors, which will play an important supporting role in the development of the aerospace industry in China.

"The release of this set of system and database can greatly reduce the work in the early stage of the design department, thus speeding up the development process. In the future, people can look for the suitable [ airfoil design] in our system according to their performance requirements. If they have more specific requirement, they can use this system as a basis, and our supporting design software can quickly make customized airfoil to meet their requirements," said Gao Zhenghong, a professor from the School of Aeronautics of Northwestern Polytechnical University.

Egyptian President Abdel-Fattah El-Sisi held talks in Cairo on Thursday with visiting Iranian Foreign Minister Seyed Abbas Araghchi on preventing the escalating regional conflicts into a full-scale war.

The visit conducted by Araghchi, who is on a regional tour over Israeli escalation in the Gaza Strip and southern Lebanon, marks the first visit to Egypt by an Iranian foreign minister since 2013.

The Egyptian presidency said in a statement on its website that Sisi reiterated Egypt's position during the talks, calling on all parties not to expand the scope of the conflict, to stop the escalation of the situation, and to prevent the Middle East from falling into a full-scale war.

Sisi also stressed that the international community must continue to strengthen its efforts to achieve a ceasefire in the Gaza Strip and Lebanon, stop violations and aggression in the West Bank, and allow civilians' access to necessary humanitarian aids, according to the statement.

Iran's official news agency IRNA reported that Araghchi and Egyptian leaders called for strengthened consultations and coordination to end the suffering of the Lebanese and Palestinian people and prevent the conflict from expanding.

Egyptian political analysts say they believe that this visit marks an important progress in the relations between the two countries, and also reflects the common aspirations for peace and stability and concerns for current tensions among regional countries.

"This is the first visit by an Iranian foreign minister to Egypt in 12 years. This visit is of great significance, especially in the diplomatic and economic fields of the two countries. The two sides exchanged views on issues such as Palestine and Lebanon, which is conducive to jointly addressing regional challenges," said political analyst Walid.
