Bhalisela kwiMidiya yethu yeNtlalo ukuze ufumane iPosi ekhawulezileyo
IiRing Laser Gyroscopes (iiRLG) zihambele phambili kakhulu ukusukela oko zaqalwa, zidlala indima ebalulekileyo kwiinkqubo zanamhlanje zokuhamba ngenqanawa kunye nezothutho. Eli nqaku liza kugxila kuphuhliso, umgaqo, kunye nokusetyenziswa kweeRLG, ligxininisa ukubaluleka kwazo kwiinkqubo zokuhamba ngenqanawa ezingenamandla kunye nokusetyenziswa kwazo kwiinkqubo ezahlukeneyo zothutho.
Uhambo Lwembali LweeGyroscopes
Ukusuka kwiConcept ukuya kwiNavigation yanamhlanje
Uhambo lwee-gyroscopes lwaqala ngokwenziwa ngokubambisana kwe-gyrocompass yokuqala ngo-1908 ngu-Elmer Sperry, obizwa ngokuba "nguyise wetekhnoloji yanamhlanje yokuhambahamba," kunye noHerman Anschütz-Kaempfe. Kwiminyaka edlulileyo, ii-gyroscopes ziye zabona uphuculo olukhulu, zaphucula ukusetyenziswa kwazo ekuhambeni nasekuthuthweni. Olu phuculo luye lwavumela ii-gyroscopes ukuba zibonelele ngesikhokelo esibalulekileyo sokuzinzisa uhambo ngeenqwelo-moya kunye nokwenza ukuba imisebenzi ye-autopilot iqhubeke. Umboniso ophawulekayo kaLawrence Sperry ngoJuni 1914 wabonisa amandla e-gyroscopic autopilot ngokuzinzisa inqwelo-moya ngelixa imi kwi-cockpit, nto leyo ebonisa inyathelo elikhulu phambili kubuchwepheshe be-autopilot.
Ukutshintshela kwiRing Laser Gyroscopes
Utshintsho lwaqhubeka ngokusungulwa kwe-ring laser gyroscope yokuqala ngo-1963 nguMacek noDavis. Olu tshintsho lwaphawula utshintsho oluvela kwi-mechanical gyroscopes ukuya kwi-laser gyros, eyayibonelela ngokuchaneka okuphezulu, ukugcinwa okuphantsi, kunye neendleko eziphantsi. Namhlanje, i-ring laser gyros, ingakumbi kwizicelo zasemkhosini, zilawula imarike ngenxa yokuthembeka kwazo kunye nokusebenza kakuhle kwiindawo apho imiqondiso yeGPS ichaphazeleka khona.
Umgaqo weRing Laser Gyroscopes
Ukuqonda isiphumo seSagnac
Umsebenzi oyintloko wee-RLGs ukwikhono lazo lokuchonga indlela into ebekwe ngayo kwindawo engenamandla. Oku kufezekiswa ngesiphumo seSagnac, apho i-interferometer yeringi isebenzisa imisebe yelaser ehamba kwicala elahlukileyo ejikeleze indlela evaliweyo. Ipateni yokuphazamiseka eyenziwe yile misebe isebenza njengendawo yokubhekisa engashukumiyo. Naluphi na ushukumo lutshintsha ubude bendlela yale misebe, nto leyo ebangela utshintsho kwipateni yokuphazamiseka ngokulingana nesantya se-angular. Le ndlela inobuchule ivumela ii-RLG ukuba zilinganise indlela ebekwe ngayo ngokuchanekileyo ngaphandle kokuxhomekeka kwiireferensi zangaphandle.
Izicelo zoKuhamba ngeNdlela kunye nokuThutha
Ukuguqula iiNkqubo zokuHamba ezingasebenziyo (i-INS)
Ii-RLG zibalulekile ekuphuhlisweni kwe-Inertial Navigation Systems (INS), ezibalulekileyo ekukhokheleni iinqanawa, iinqwelomoya, kunye nee-missile kwiindawo ezinqatshelwe yi-GPS. Uyilo lwazo oluncinci nolungangqubaniyo luzenza zibe zilungele ukusetyenziswa kwezi ndlela, nto leyo enegalelo kwizisombululo zokuhamba ezithembekileyo nezichanekileyo.
Iqonga Elizinzileyo vs. I-Strap-Down INS
Ubuchwepheshe be-INS buye batshintsha baba ziinkqubo zeqonga elizinzileyo kunye neenkqubo ezithintela imitya. Iqonga elizinzileyo i-INS, nangona inobunzima boomatshini kunye nokuguguleka kwayo, inikezela ukusebenza okuqinileyo ngokudibanisa idatha ye-analog.Kwelinye icala, iinkqubo ze-INS ezisebenzisa imitya zixhamla kwi-RLGs ezixineneyo nezingenalo ulondolozo, nto leyo ezenza zibe lukhetho olukhethwayo kwiinqwelo-moya zanamhlanje ngenxa yokuba zisebenza kakuhle kwaye zichanekile.
Ukuphucula Ukuhamba kweMissile
IiRLG zikwadlala indima ebalulekileyo kwiinkqubo zokhokelo lwezixhobo ezikrelekrele. Kwiindawo apho iGPS ingathembekanga khona, iiRLG zibonelela ngenye indlela ethembekileyo yokuhamba. Ubungakanani bazo obuncinci kunye nokumelana namandla agqithisileyo kuzenza zilungele imijukujelwa kunye neembumbulu zezixhobo, eziboniswe ziinkqubo ezifana neTomahawk cruise missile kunye neM982 Excalibur.
Umzobo womzekelo weqonga elizinzileyo le-gimbaled inertial eliqinisiweyo kusetyenziswa ii-mounts. Ngobubele be-Engineering 360.
