Ofufuza a ku yunivesite ya Pennsylvania akwanitsa kutulutsa zinthu pogwiritsa ntchito kuwala koyambirira kwa zomwe zingakhale zofanana ndi kapeti yamatsenga mu nkhani za ana. Izi zikutanthauza kuti m'tsogolomu, ndege zazing'ono zimayendetsedwa ndi dzuwa Zitha kuwulukira mu mesosphere wosanjikiza wa mlengalenga wa Dziko Lapansi womwe umayenda pakati pa 50 km ndi 80 km mumtunda.
Pamwamba pake, mlengalenga ndi woonda kwambiri ndipo muli 0.1% yokha ya mpweya wonse. Pansi pazimenezi, ndege ndi mabuloni sangathe kuthawa koma luso latsopanoli likhoza kulola ndege zazing'ono kwambiri kuti zigwire ntchito zofufuza zomwe zili ndi chidwi chachikulu cha sayansi mu mesosphere.
ZINTHU ZONSE ZAMBIRI
Ma disks owuluka Kuti akwaniritse kuyatsa ndi kuwala, ofufuzawo adadula ma discs kuchokera ku zinthu zowonekera zotchedwa polyethylene terephthalate, yomwe imadziwikanso kuti Mylar kapena Melinex. Ndi mtundu wa pulasitiki womwe umagwiritsidwa ntchito kwambiri muzopaka zakumwa ndi nsalu. Ndi polima yomwe ili m'gulu la zinthu zopangidwa ndi polyesters.
Ma disks a Mylar, 6 millimeters m'mimba mwake, adakutidwa m'mphepete mwawo ndi ma carbon nanotubes, omwe ali ndi magetsi apamwamba komanso matenthedwe. Ma diskiwo anaikidwa m’chipinda cha vacuum chopangidwa ndi zinthu za acrylic, pamodzi ndi ma LED (light-emitting diode) asanu ndi atatu omwe amaika mphamvu zawo pa thireyi ziŵiri zazing’ono zapulasitiki. Pamene kutentha koyenera kunafika, ma disks anayamba kuyendayenda mkati mwa chipindacho ndi kupanikizika komwe kumafanana ndi mesosphere.
ZIKOMO KWA NANOTUBES
Chifukwa cha ma nanotubes Monga tafotokozera m'magazini ya ScienceNews, ma nanotubes a carbon ndi omwe amalola kuti ma disks azituluka chifukwa amayamwa kuwala ndi kutentha chimbale. Chifukwa cha mawonekedwe a nanotubes mamolekyu a mpweya amapeza mphamvu akawombana ndi diski yotenthetsera, ndikuthamanga kwambiri. Mphamvu zowonjezerazo zimamasulira kukhala mamolekyu othamanga omwe amadumpha pansi pa disk ya Mylar mofulumira kuposa pamwamba, motero amachititsa kuti awonongeke pang'ono, amphamvu kwambiri.
Wired ikuyembekeza kugwiritsa ntchito ukadaulo uwu ndi nthawi yoyamba ya ndege yokhazikika ya photophoretic (yoyendetsedwa ndi kuwala) yomwe imatengera momwe ma mbale osiyanasiyana angachitire mumlengalenga.
DISO PA MESOSPHERE
Diso pa mesosphere Zotsatira zake zikuwonetsa kuti levitating disk, ngati kapeti yaying'ono yamatsenga, imatha kuwuluka mu mesosphere itanyamula chiwongolero cha kukula kwa sensa yomwe ingathandizire kuphunzira zanyengo ndi nyengo kuchokera pamalingaliro atsopano. Mesosphere imadutsa ndi nyenyezi zowombera, kuwala kochokera kumlengalenga kwamitundu yosiyanasiyana, ndi tinthu tating'ono tamphamvu tomwe timayambitsidwa ndi mphepo yamkuntho ya dzuŵa yomwe imakhudza ozoni.
Kukhala ndi wowonera mumlengalenga wochepa kwambiri wa mlengalenga wa Dziko Lapansi ndi chikhumbo chakale cha sayansi chomwe tsopano chikukonzekera kuti chitheke, ngakhale ukadaulo womwe umalola kuti uyenerabe kuthana ndi zovuta zina kuti zitheke. Ma discs amatha kuyendetsedwa ndi kuwala kwa dzuwa kapena ma lasers ndipo tsiku lina amanyamula zida zazing'ono kuti athe kuyeza momwe zinthu zilili mu mesosphere yomwe ofufuzawo akuganiza.
SMART FULU
Fumbi lanzeru Chitsanzo cha photospheric levitation chomwe chinapezedwa mu kafukufukuyu chimatilola kuwerengera momwe zinthu zazing'ono zowulukazi zidzakhalire mosiyanasiyana komanso mosiyanasiyana mumlengalenga. Zakhazikitsa, mwachitsanzo, kuti diski ya 6-centimeter-diameter imatha kunyamula malipilo a 10-milligram pamene levitating ndi dongosolo ili, zokwanira kuthandizira masensa anzeru fumbi. Smart fumbi ndi netiweki yopanda zingwe ya masensa ang'onoang'ono omwe amatha kuzindikira ma sign kuchokera ku kuwala, kutentha, kugwedezeka, ndi zina zambiri zochokera ku chilengedwe.
