An Interview With Wang Yongzhi, “CH” UAV Technology Expert: Decrypt Large-Scale Stealth UAV

On the 5th, on the eve of the opening of the 12th China International Aeronautics and Astronautics Fair (hereinafter referred to as Zhuhai Air Show), many media reporters saw a large size at the stand of the 11th Research Institute of China Aerospace Science and Technology Group Co., Ltd. It looks a bit like the American X-47B 's mysterious wing drone, which, according to the scene, is called CH-7.

CH-7 flying wing layout leads to conjecture.

Its huge wingspan accounts for almost two-thirds of the width of its pavilion, and under the giant wing of CH-7, CH's latest CH-10 unmanned tiltrotor is even more "small".  

The CH-7 is a high-altitude, subsonic and stealth UAV, currently in the detailed design stage, and it was displayed in the form of a full-size prototype this time, with a maximum take-off weight of 13 tons and a wingspan of 22 meters,. It has strong stealth and penetration capabilities.

According to Wang Yongzhi, the CH-7 will continue to inherit the high reliability, high attendance, universal ground station and automatic control technology, etc. of the CH-4 and CH-5, and will also adopt a series of advanced technologies that have not been used before.

The CH-7 can be used as a "bodyguard" for the fourth generation.  

Why launching a stealth drone now? Wang Yongzhi said that the CH-7 could carry out relevant combat tasks in high-risk environments. High-altitude, high-speed and stealth will be the development trend of high-end drones, so we launched the CH-7 UAV.  

The maximum take-off weight of the CH-7 can reach 13 tons. Wang Yongzhi said that it was characterized by long voyage time and it could be continuously monitored in high-risk environments. The powerful mounting ability enabled it to mount more advanced reconnaissance loads and more attack weapons, and perform immediate missions on enemy high value targets.  

When talking about the future development direction of the stealth UAV, Wang Yongzhi said that the CH-7 was mainly based on meeting China's own relevant equipment development needs, if it was in line with the country's export policy, it would also help friendly countries to raise their national defense levels. 

The ocean may be the next direction for application.  

CH now has a series of models ranging from 2.2 kg to 3.3 tons of maximum take-off weight. It has the most complete military UAV series in China at present. With the development of the CH-7, which has a maximum take-off weight of 13 tons, the serialization and development of CH UAV will be further improved. According to experts, relying on the great advantages of heavy load and long voyage, CH-5 is suitable for various weapons, which is very flexible, and it can also be committed to civilian and maritime patrols in the sea. It is understood that the CH-10 is a new type of UAV that integrates helicopter technology with fixed-wing aircraft technology. CH-10 can perform reconnaissance, detection, communication relay, search, target indication, relay guidance and other tasks. 

The CH-7 currently developed is mainly aimed at land-based takeoff and landing. In accordance with the requirements of shipborne take-off and landing, and marine environmental use, it has the capability to be converted to shipboard in the future, and at the same time, the CH-7 will also enhance China's ability to defend maritime rights and interests after mounting mission loads such as radar searching.
