It is called XG-1. With a payload of 30 heavily armed paratroopers and 2 main and co-pilots, it can also be used to transport cargo. It is a dual-purpose gliding aircraft that enters the enemy in an unpowered and covert way. Germany had this precedent in World War II, but it could only carry more than 10 heavily armed paratroopers, and the gliding transport aircraft developed by Wang Zhu could carry 30 paratroopers, which can be said to be a giant glider. Unfortunately, it was developed in early 1946, and the Anti-Japanese War was over and failed to play its expected role. In addition to landing gears, instruments and control systems, the aircraft is all made of bamboo and wood composite structures, which is unprecedented in the world. It is a bold attempt and innovation in the history of Chinese aviation and even in the history of world aviation.
