Weight is less than 1 gram of minimum solar aircraft flight

Solar photovoltaic (pv) net news: according to report of Xinhua News Agency, the world's smallest aircraft is a drone, less than 1 gram weight, a lab test successfully in the United States.

according to the international energy research center, currently the nation's largest arrangement in energy storage project, nantong rudong county in jiangsu province was put into operation recently system consists of seven 180 kw / 1. 1 MWH container type of energy storage system, the total installed capacity of 1. 26MW/7. 7 MWH, runtime SOC set to 90%, effective capacity for 7 MWH.

this drone called & other; Machine bee & throughout; , driven by solar energy. It is made of ceramic & other; Artificial muscles & throughout; After electrify can automatically adjustable, drive 4 pieces as thin as cicada's wings, flap 120 times per second. 26 according to the British 'nature' magazine published research report, the drone weight of 90 mg, carrying 60 mg solar arrays and 91 mg signal generator, without external force test successfully for the first time, flight time of 1 second.

existing batteries on the market, even the smallest than & other; Machine bee & throughout; Heavy. Involved in the research of Harvard University wes bionic engineering, Robert & middot; Wood said: & other; We have to study countermeasures, solve vehicle efficiency problem, develop super light power circuit and adopt high efficiency solar cells. ” After several times, the researchers for & other; Machine bee & throughout; Add a second pair of wings, improve the efficiency of the flight. The researchers Noah & middot; Jia said he and other Let it have a more lift, at the same time will not consume more power. ”

test successful & other; Machine bee & throughout; Wingspan. 3. 5 cm. Its solar cell single weight 10 mg, per mg was strongest when the sun battery power generation 0. 76 milliwatts. Even if effective, & other; Machine bee & throughout; Still need three energy generated by the light intensity of the sun to flight, so I can't fly in the outdoor. In the laboratory, the researchers used a halogen lamp simulate enough light intensity, make & other; Machine bee & throughout; Test flight a success.
