For example, he divided each wing into three equal parts and made a downward fold so that a triangular "air channel" was formed where the wings attached to the body. From here he went on to develop various designs of this "air channel plane" that extended and enlarged the channel, creating a plane with a delta-shaped wing similar to a hang glider.
例如，將兩側機翼分成三等份，往下摺，機翼和機身連接的地方就會形成一條三角形的「氣溝」；由此再發展出不同造型，把「氣溝紙飛機」的氣溝再向外延伸加大，就變成一架長三角翼、類似滑翔翼的紙飛機。
