A Closeup Look at China's Divine Eagle Drone
A Closeup Look at China's Divine Eagle Drone. HT: Popsci.
By using the single deck bus in the background (probably 3.2 meters tall, like most buses of its type) as a very crude visual yardstick, a very rough comparison suggests that the Divine Eagle is about 6 meters tall, and 15 meters long (since most high altitude large UAVs have a wingspan to body length ratio of 2.5:1 to 3:1, the wingspan of the Divine Eagle is likely its be 35 to 45 meters across). With a maximum take off weight of at least 15 tons, the Divine Eagle is the world's largest UAV, edging out the RQ-4 Global Hawk.
In late June 2015, new photos emerged of the Divine Eagle prototype, allowing a clearer look at its details. The Divine Eagle has a single engine nestled between its tailfins, with a diameter of over 1 meter.
This makes the engine likely to be a medium non-afterburning turbofan producing 3 to 5 tons of thrust, which in turn is usually enough to power a UAV of 12-18 tons in maximum takeoff weight. In comparison, the largest American UAV in open service, the RQ-4 Global Hawk, uses a F-137-RR-100 turbofan engine with 3.4 tons of thrust. The Divine Eagle has a five wheel landing gear layout.
