Iphrinta ye-3D engaphansi kwamanzi ephrinta ukhonkolo ngqo phansi kolwandle yenziwe e-US.

Abacwaningi eCornell University ithuthukisiwe Ubuchwepheshe bokunyathelisa be-3D bezakhiwo zekhonkrithi ngqo phansi kolwandle. Le phrojekthi, exhaswe yi-DARPA, ihlose ukwenza ukwakhiwa nokulungiswa kwezakhiwo zolwandle ngaphansi kwamanzi kube ngokushesha, kushibhile, futhi kuphephe. ​​Izindlela zendabuko ziyabiza, zidla isikhathi, futhi ziphazamisa uhlelo lwemvelo lwasolwandle, okuyinto edingekayo uma kungekho ezinye izindlela.

Ososayensi bathole isibonelelo sika-$1,4 million esivela ku-DARPA kanye nohlu lwezidingo okumele zihlangatshezwe ukuze kutholakale uxhaso olwengeziwe. Esinye sezidingo ezibalulekile kwakuwukusetshenziswa kwenhlabathi engaphansi kolwandle njengesithako esiyisisekelo senhlanganisela yekhonkrithi yokunyathelisa ngaphansi kwamanzi kwe-3D. Lokhu kuqinisekisa ubungane obukhulu bemvelo futhi kunciphisa umthwalo wezokuthutha. Ukwakhiwa kungenziwa endaweni, kunciphisa izindleko zokuthutha izingxenye ziye endaweni ekude.

Isihluthulelo sempumelelo yale phrojekthi, ngokusho kwethimba, ukunqoba ukuhlanzwa kwezinto. Inselele enkulu yokunyathelisa ngaphansi kwamanzi kwe-3D ukuthi ingxube yesamente igezwa ngamanzi ngaphambi kokuba iqine. Ososayensi baxazulule le nkinga ngokwenza ngcono ibhalansi phakathi kokuthamba kwezinto kanye nokumpompa kwazo. Ikhonkrithi yakhiwe ngokuyinhloko ngodaka olungaphansi kolwandle—imfuneko ye-DARPA, njengoba kuphawuliwe ngenhla. Iphrinta enkulu ye-3D yezimboni enesisindo esingaba ngu-2700 kg, eyayisetshenziswa ngaphambilini ukunyathelisa izakhiwo ezinkulu emhlabeni, yalungiselelwa ukusetshenziswa ngaphansi kwamanzi. Okungenani yayikwazi ukunyathelisa echibini ngaphandle kokucwiliswa ngokuphelele.

Enye inselele eyethulwe yizinzwa zezithombe kwakuwukungakwazi kwazo ukulawula kahle uhlelo lokuphrinta emanzini amnyama. Ngakho-ke, ososayensi bathuthukise izinhlelo ezintsha zezinzwa ezivumela ukulawula okunembile inqubo yokuphrinta ngisho nasezimweni zokubonakala okuphansi kakhulu. Ukuhlolwa kwenziwe emathangini amanzi amakhulu, lapho babonise khona ukuphrinta okuphumelelayo ngaphansi kwamanzi ngaphandle kokuphazamiseka okukhulu kwemvelo. Ubuchwepheshe bubonisa ukuthi izakhiwo zingakhiwa noma zilungiswe ngqo endaweni ngaphandle kokuletha izinto phezulu noma kudingeke ababhukudi.

Ithimba leCornell liphakathi kwamaqembu ayisithupha ahlanganyela emncintiswaneni we-DARPA. Lo mncintiswano uzoba ngoMashi walo nyaka, lapho iqembu ngalinye kuzodingeka liphrinte khona i-arch engaphansi kwamanzi ngokwemigomo ecacisiwe. Ukuphothulwa ngempumelelo kwale miboniso kuzoqinisekisa amandla obuchwepheshe bokusetshenziswa komhlaba wangempela ekwakhiweni kwamanzi. Lokhu kuthuthukiswa sekuvele kubhekwa njengesinyathelo esibalulekile sokuguqula izindlela zokudala nokugcina izakhiwo ezingaphansi kwamanzi. Lokhu kungafaka izisekelo zama-wind turbine, izakhiwo zezikhungo zedatha ezingaphansi kwamanzi, kanye nezinye ingqalasizinda.
