According to Taiwan “in the Canton News” reports, the first aircraft to use “fuel cell and lithium battery” hybrid unmanned aircraft “gray-faced buzzard No.” End maiden flight today. According to reports, this is Asia’s first aircraft with payload capacity of high altitude and long flight endurance unmanned flight systems hybrid aircraft, the future is expected to apply to military use or disaster relief system.
According to reports from Taiwan Cheng Kung University Department of Aerospace Engineering, Professor Lai Weixiang team developed the “gray-faced buzzard number”, today in Pingtung flight to flight speed of 80 to 100 km, with a total flight distance of about 30 km smoothly.
“Central News Agency,” the report said, “gray-faced buzzard No.” design features as the wingspan of 3.4 meters, weighing up to 30 kg, 4 kW brushless motor, and the 1 kW fuel cell with 5400mAh Li-ion battery hybrid. Currently less than 22 kg total weight, may still hold about 8 kg of lithium batteries or hydrogen fuel in the future there may be a considerable expansion of space.
Lai Weixiang professor said, “gray-faced buzzard No.” hybrid fuel cell and lithium battery with a low cost (about saving three-quarters), test period is short, the advantages of rapid firing, and the resolution of no less than satellite; When the planes take-off Li-ion battery output bigger, higher, the fuel cell can self-produced hydrogen, can fly longer and unmanned aircraft to take off when the power is about 2.5 kW, but will fly overhead, left after the 800 watts, only 1 / 3. If you rely on fuel cells, then one simply is not enough, a combination of both, relatively more efficient, more economical.
Professor Lai Weixiang said that the plane sound small, and total weight of less than 22 kilograms, can not accommodate more space, the future can be used in military intelligence gathering, disaster investigation. He hoped the second half of the challenges will be flying three hours, even flying around the island.
