The Guizhou WZ-7 Soaring Dragon (Chinese: 无侦-7 翔龙) is a high-altitude long endurance unmanned aerial vehicle (UAV) from the People's Republic of China.[1][4] The design uses a "unique" joined-wing design.[4]
The WZ-7 has a similar role and mission to the Northrop Grumman RQ-4 Global Hawk operated by the United States Air Force .[5] The primary mission is expected to be aerial reconnaissance, but it may also be fitted to provide targeting data for anti-ship ballistic missiles and cruise missiles.[5]
Development
The WZ-7 was designed by the Chengdu Aircraft Industry Group and constructed by the Guizhou Aircraft Industry Corporation. A model appeared at the 2006 China International Aviation & Aerospace Exhibition.[6] In 2011, it had not yet flown and radar cross-section and other electromagnetic tests were ongoing.[6] The UAV was officially unveiled at the 2021 exhibition.[4]
The WZ-7 entered serial production in 2015 to 2016.[2]
Design
Large by the standards of UAVs, the WZ-7's tandem, joined-wing design allows for a more rigid, less flexible wing than other configurations, with benefits said to include an increased lift-to-drag ratio and less complex flight controls than a HALE UAV with a conventional wing would require.[7][6][5] The aircraft is powered by a Guizhou WP-13 turbojet engine, a copy of the Soviet Tumansky R-13; it is anticipated that a newer, improved engine, will be installed in production aircraft.[6] The air intake for the engine is mounted atop the fuselage, with the engine itself mounted in the rear of the aircraft.[6]
Operational history
The WZ-7 entered service with the People's Liberation Army Air Force in 2018[1] and were spotted deployed to the Tibet Autonomous Region, Hainan Island and Yishuntun Airbase near North Korea.[8]
On 24 July 2019, a WZ-7 shadowed the American Ticonderoga-class cruiser USS Antietam which was transiting the Taiwan Strait.[9]
