<p>Lethuphuong89: </p> <hr /> <div>Solar Storm is the result of a conceptual design study for a Hybrid-Solar cell powered MAV. And as far as I can search through the internet Solar Storm is the smallest solar MAV (which is autonomous) in the world (please correct me if I am wrong...).<br /> <br /> Frame is especially designed for its particular flight conditions by using computer aided drafting and moulds have been milled precisely with a 3-axis CNC in order to achieve the designed shape and surface quality. 20 [http://www.azurspace.com/ S32 Solar cells] bonded under vacuum by the help of a silicon based special glue from [http://www.map-coatings.com/ MAP-Coatings].<br /> <br /> You can also check out [http://paparazzi.enac.fr/wiki/Fire-Storm Fire Storm] page to see a version without solar cells.<br /> <br /> <br /> [[Image:SolarStorm1.jpg|600px|Solar Storm]]<br /> <br /> <br /> == Specifications ==<br /> *'''Span:''' 500 mm<br /> *'''Weight:''' 300 g<br /> *'''Solar cells:''' 20 cells, serially linked for a maximum theoretical power of 6.5W<br /> *'''MPPT:''' Custom designed Maximum Power Point Tracker<br /> <br /> == Performances ==<br /> <br /> '''24 September 2009 '''<br /> <br /> The third flight of Solar-Storm (with 1320mAH battery) has just finished :)<br /> Achieved endurance is:<br /> <br /> *'''New Endurance:''' '''90''' minutes. <br /> <br /> '''11 September 2009 '''<br /> <br /> Solar-Storm has only 2 test flights yet. First to tune :) and second to measure the endurance.<br /> <br /> The numbers we got from the first flight test (by using only 730mAH battery) are encouraging:<br /> <br /> *'''Endurance:''' 53 minutes<br /> *'''Average level-flight consumption:''' 11-12 W<br /> *'''Average power from Solar cells:''' ~4-5 W <br /> <br /> Note: It was a partially cloudy day, sun was hiding behind the clouds for 20 minutes of the flight. <br /> <br /> The following plot show power numbers for 7 minutes. From top to bottom, the curves show:<br /> * (purple) The voltage (V) of the solar cells array<br /> * (orange) The power (W) of the solar cells array extracetd through the MPPT.<br /> * (green) The total current (I) consumed by the whole system<br /> * (blue) The current (I) going out of the battery.<br /> <br /> We can observe on the last curve that the battery was sometimes charged in flight !<br /> <br /> [[Image:Solarplot.png|700px|Solar Plot]]<br /> <br /> Solar-Storm will be capable of flying more than 145 minutes at its designed conditions. But not tested yet :)<br /> <br /> == Acknowledgements==<br /> Thanks a lot to [http://www.map-coatings.com/ MAP Coatings Company] for helping us in the hard bonding process of solar cells on to the wing.<br /> <br /> [[Category:Airframes]]<br /> <br /> <br /> [[http://baovevn.vn/cong-ty-tu-van-nghiep-vu-bao-ve/ cong ty bao ve]]<br /> [[http://uvc-thanhlapcongty.com/dang-ky-online/dang-ky-thanh-lap-doanh-nghiep.html thành lập doanh nghiệp]]<br /> [[http://thutucthanhlapcongty.net/index.php/dich-vu-tu-van-tim-ke-toan/ dịch vụ kế toán]]<br /> [[http://www.cuudulieu24h.com cuu du lieu]]<br /> [[http://noithathoangduy.com.vn noithat]]<br /> [[http://ihrp.fis.com.vn/ Phần mềm nhân sự]]<br /> [[http://ihrp.fis.com.vn/ Quản lý Nhân sự]]<br /> [[http://ihrp.fis.com.vn/ Phần mềm quản lý nhân sự tiền lương]]<br /> [[http://thamtuthanglong.com/ tham tu]]<br /> [[http://thamtuthanglong.com/ cong ty tham tu]]</div>
