Ib pab neeg los ntawm NASA's Langley Research Center thiab cov koom tes los ntawm NASA's Ames Research Center, Nano Avionics, thiab Santa Clara University's Robotics Systems Laboratory tab tom tsim lub hom phiaj rau Advanced Composite Solar Sail System (ACS3).Lub teeb yuag sib xyaw ua ke boom thiab lub hnub ci sail system, uas yog, thawj zaug kev sib xyaw boom siv rau hnub ci sails ntawm txoj kev.
Lub kaw lus yog siv los ntawm lub hnub ci zog thiab tuaj yeem hloov cov foob pob hluav taws thiab hluav taws xob propulsion systems.Kev cia siab rau lub hnub ci muab cov kev xaiv uas tej zaum yuav tsis muaj peev xwm tsim lub dav hlau.
Lub boom sib xyaw yog siv los ntawm 12-unit (12U) CubeSat, tus nqi-zoo nano-satellite ntsuas tsuas yog 23 cm x 34 cm.Piv nrog rau cov tsoos hlau deployable boom, ACS3 boom yog 75% sib dua, thiab thermal deformation thaum rhuab yog txo los ntawm 100 zaug.
Ib zaug nyob rau hauv qhov chaw, CubeSat yuav sai sai xa cov hnub ci array thiab xa cov kev sib xyaw ua ke, uas tsuas yog siv sijhawm 20 mus rau 30 feeb.Lub square sail yog ua los ntawm cov khoom siv polymer hloov tau nrog cov pa roj carbon fiber ntau thiab yog li 9 meters ntev ntawm txhua sab.Cov khoom siv sib xyaw no zoo tagnrho rau kev ua haujlwm vim tias nws tuaj yeem dov rau kev khaws cia, tab sis tseem tuav lub zog thiab tiv thaiv kev khoov thiab kev sib hloov thaum raug kub hloov.Lub koob yees duab onboard yuav sau cov duab thiab sib dhos ntawm lub nkoj xa mus rau kev soj ntsuam.
Cov thev naus laus zis tsim los rau kev sib xyaw ua ke rau lub hom phiaj ACS3 tuaj yeem txuas ntxiv mus rau yav tom ntej hnub ci txoj haujlwm ntawm 500 square metres, thiab cov kws tshawb fawb tau ua haujlwm los tsim lub hnub ci sails loj li 2,000 square meters.
Lub hom phiaj ntawm lub hom phiaj muaj xws li kev sib sau ua ke sails thiab xa cov khoom sib xyaw ua ke hauv qhov chaw qis los ntsuas cov duab thiab tsim kev ua tau zoo ntawm lub nkoj, thiab khaws cov ntaub ntawv ntawm kev ua haujlwm sail los muab cov ntaub ntawv rau kev txhim kho cov tshuab loj dua yav tom ntej.
Cov kws tshawb fawb cia siab tias yuav sau cov ntaub ntawv los ntawm ACS3 lub hom phiaj los tsim cov tshuab yav tom ntej uas tuaj yeem siv rau kev sib txuas lus rau kev tshawb nrhiav cov neeg ua haujlwm, huab cua huab cua ceeb toom satellites, thiab asteroid reconnaissance missions.
