Abstract: The importance and necessity of aircraft drag reduction design are emphasized by analyzing the target of aircraft drag reduction proposed by green aviation, and the laminar wing technology is considered an important approach to aircraft drag reduction. After reviewing the development of laminar wing design, research, and verification, this paper identifies the gap and technical problems between the laminar wing technology and the aircraft design industry. The potential and development direction of the laminar wing technology are analyzed, and the feasibility of this technology in future aircraft design evaluated.

Key words: green aviation, laminar wing, drag reduction, wind tunnel test, flight test
