Chinese "Global Hawk" debut! Similar performance, only one-tenth of the cost, can fly across intercontinental
Recently, a peculiarly shaped large-scale UAV system debuted at the Zhuhai Air Show. This new weapon system, called the Rainbow-6 high-altitude long-endurance UAV, was developed by the 11th Academy of China Aerospace Science and Technology Corporation. Aiming at the world's large-scale high-end military dual-purpose UAV market, the institute independently researches and develops a new type of high-altitude, high-speed, long-endurance, and multi-passage UAV.
According to foreign media reports, the Rainbow-6 UAV system is a cutting-edge product specially developed for the foreign large-scale military UAV market. Due to the thin air in the flying environment of high-altitude long-endurance UAVs, the flight Reynolds number is low, and when cruising The required lift coefficient is large, so the Rainbow-6 UAV adopts a conventional aerodynamic layout with a small sweep angle with a wingspan of 20 meters, a large aspect ratio main wing and a T-shaped tail. This structure is similar to the Rainbow-T4 The aerodynamic layout of the solar-powered long-endurance UAV is similar, and the wingtip of the Rainbow-6 UAV is equipped with winglets, which can greatly improve the flight range and endurance of the aircraft.
It is understood that at present, the military model of the Rainbow-6 UAV system can be divided into long-range reconnaissance and attack models through the replacement of payloads and aircraft modular components. The long-range reconnaissance model can reach more than 20 hours in flight time, and the flight distance With an intercontinental range of up to 11,000 kilometers or carrying 2 tons of ammunition, it is already close to the US "Global Hawk" strategic reconnaissance drone. However, the cost of the Rainbow 6 UAV is estimated to be only one-tenth of the "Global Hawk" strategic reconnaissance UAV, which is extremely cost-effective.
