Ithimba elivela eLangley Research Center ye-NASA kanye nabalingani abavela e-Ames Research Center ye-NASA, i-Nano Avionics, kanye ne-Robotics Systems Laboratory yaseSanta Clara University bathuthukisa umsebenzi we-Advanced Composite Solar Sail System (ACS3). I-composite boom elula engasetshenziswa kanye nesistimu ye-solar sail, okungukuthi, okokuqala ngqa i-composite boom isetshenziselwa amaseyili elanga emzileni.
Lolu hlelo lusebenza ngamandla elanga futhi lungathatha indawo yama-rocket propellant kanye nezinhlelo zikagesi zokuqhuba. Ukuthembela elangeni kunikeza izinketho ezingase zingenzeki ekwakhiweni kwemikhumbi-mkhathi.
I-composite boom isetshenziswa yi-12-unit (12U) CubeSat, i-nano-satellite engabizi kakhulu elinganisa u-23 cm x 34 cm kuphela. Uma kuqhathaniswa ne-boom yensimbi evamile engasetshenziswa, i-ACS3 boom ilula ngo-75%, kanti ukuguquguquka kokushisa uma kushiswa kuncishiswa izikhathi eziyi-100.
Uma isisemkhathini, i-CubeSat izosebenzisa ngokushesha i-solar array bese isebenzisa i-composite boom, ethatha imizuzu engama-20 kuya kwengama-30 kuphela. Iseyili yesikwele yenziwe ngezinto ze-polymer eziguquguqukayo eziqiniswe nge-carbon fiber futhi ingamamitha ayi-9 ubude ohlangothini ngalunye. Le nto ehlanganisiwe ilungele imisebenzi ngoba ingagoqwa ukuze igcinwe incane, kodwa isagcina amandla futhi imelana nokugoba nokugoba lapho ivezwa izinguquko zokushisa. Ikhamera engaphakathi izoqopha ukuma nokuqondana kweseyili esetshenzisiwe ukuze ihlolwe.
Ubuchwepheshe obuthuthukiswe ukuze kuthuthukiswe umkhankaso we-ACS3 bunganwetshwa kuze kube semisebenzini yelanga yesikhathi esizayo engamamitha-skwele angu-500, futhi abacwaningi basebenza ukuthuthukisa amaseyili elanga amakhulu angamamitha-skwele angu-2,000.
Imigomo yalo msebenzi ihlanganisa ukuhlanganisa ngempumelelo amaseyili nokufaka ama-boom ahlanganisiwe endaweni ephansi yokuhlola ukuma nokusebenza kahle kwamaseyili, kanye nokuqoqa idatha ngokusebenza kweseyili ukuze kuhlinzekwe ulwazi lokuthuthukiswa kwezinhlelo ezinkulu zesikhathi esizayo.
Ososayensi banethemba lokuqoqa idatha evela emsebenzini we-ACS3 ukuze baklame izinhlelo zesikhathi esizayo ezingasetshenziswa kwezokuxhumana emisebenzini yokuhlola enabantu, amasathelayithi okuxwayisa ngesimo sezulu esisemkhathini, kanye nemisebenzi yokuhlola ama-asteroid.
