IRingi yeLaser Gyroscopes (RLGs) ihambele phambili kakhulu ukusukela oko yaqalayo, idlala indima ebaluleke kakhulu kwiinkqubo zangoku zokuhamba kunye nezothutho. Eli nqaku lijonge ekuphuhliseni, umgaqo, kunye nokusetyenziswa kwe-RLGs, ebonisa ukubaluleka kwabo kwiinkqubo zokuhamba nge-inertial kunye nokusetyenziswa kwazo kwiindlela ezahlukeneyo zokuthutha.
Uhambo lweMbali yeeGyroscopes
Ukusuka kwiNgcaciso ukuya kwiNavigation yanamhlanje
Uhambo lwe-gyroscopes lwaqala ngokwenziwa ngokubambisana kwe-gyrocompass yokuqala ngo-1908 ngu-Elmer Sperry, obizwa ngokuba "nguyise wobuchwephesha bokuhamba ngenqanawa," kunye noHerman Anschütz-Kaempfe. Ukutyhubela iminyaka, iigyroscopes ziye zabona ukuphucuka okukhulu, ukomeleza usetyenziso lwazo kwindlela yokuhamba kunye nokuthutha. Olu phuculo lwenze ukuba i-gyroscopes ibonelele ngesikhokelo esibalulekileyo sokuzinzisa iinqwelomoya zeenqwelomoya kunye nokwenza imisebenzi yohambo oluzenzekelayo. Umboniso ophawulekayo owenziwa nguLawrence Sperry ngoJuni ka-1914 wabonisa ukubanakho kwe-gyroscopic autopilot ngokuzinzisa inqwelo-moya ngelixa wayemi kwindawo yokukhwela abaqhubi, ephawula umtsi obalulekileyo ohamba phambili kubuchwepheshe bokuzihambela.
Inguqulelo kwiRingi yeLaser Gyroscopes
Indaleko yaqhubeka kunye nokuyilwa kwe-laser gyroscope yokuqala yeringi ngo-1963 nguMacek noDavis. Olu tshintsho luphawule utshintsho ukusuka kwi-gyroscopes yoomatshini ukuya kwi-laser gyros, ebonelela ngokuchaneka okuphezulu, ukugcinwa okuphantsi, kunye neendleko ezincitshisiweyo. Namhlanje, i-laser gyros yeringi, ngakumbi kwizicelo zasemkhosini, zilawula imarike ngenxa yokuthembeka kunye nokusebenza kakuhle kwindawo apho imiqondiso yeGPS ithotywa emngciphekweni.
Umgaqo weRingi yeLaser Gyroscopes
Ukuqonda i-Sagnac Effect
Umsebenzi ongundoqo we-RLGs usekukwazini kwazo ukumisela ukuqhelaniswa kwento kwindawo engasebenziyo. Oku kufezekiswa ngesiphumo se-Sagnac, apho i-interferometer ring isebenzisa imiqadi ye-laser ehamba ngeendlela ezichaseneyo malunga nendlela evaliweyo. Ipateni yophazamiseko eyenziwe yile miqadi isebenza njengendawo yesalathiso emileyo. Nayiphi na intshukumo iguqula ubude bendlela yale miqadi, ibangela utshintsho kwipatheni yokuphazamiseka ngokomlinganiselo wesantya se-angular. Le ndlela yobuchule ivumela ii-RLGs ukuba zilinganise ukuqhelaniswa ngokuchanekileyo okukhethekileyo ngaphandle kokuxhomekeka kwiimbekiselo zangaphandle.
Izicelo kuNavigation kunye noThutho
Ukuguqula iiNkqubo zokuHamba ngokuNgaphakathi (INS)
Ii-RLGs ziluncedo ekuphuhliseni ii-Inertial Navigation Systems (INS), ezibalulekileyo ekukhokeleni iinqanawa, iinqwelomoya, kunye nemijukujelwa kwiindawo ezingafunwayo yi-GPS. Uyilo lwabo oludityanisiweyo, olungenamikhuhlane lubenza balungele usetyenziso olulolo hlobo, benegalelo kwizisombululo ezithembekileyo nezichanekileyo.
IQonga elizinzisiweyo ngokuchasene ne-Strap-Down INS
Ubuchwephesha be-INS buguqukile ukuba bubandakanye zombini iqonga elizinzileyo kunye neenkqubo zokubopha. Iqonga elizinzileyo le-INS, ngaphandle kokuntsonkotha komatshini kunye nokuchaphazeleka kokunxiba, zibonelela ngokusebenza ngamandla ngokudityaniswa kwedatha ye-analog. KwiNgakolunye uhlangothi, iisistim ze-INS ze-strap-down zixhamla kwindalo ehambelanayo kunye nokugcinwa kwe-RLGs, okwenza kube yinto ekhethwayo kwinqwelomoya yanamhlanje ngenxa yeendleko-zokusebenza kunye nokuchaneka kwazo.
Ukuphucula ukuHamba kweMissile
Ii-RLGs nazo zidlala indima ebalulekileyo kwiinkqubo zesikhokelo zeembumbulu ezihlakaniphile. Kwiimeko apho i-GPS ingathembekanga, ii-RLGs zibonelela ngenye indlela enokuthenjwa yokuhamba. Ubungakanani babo obuncinci kunye nokuchasana nemikhosi egqithisileyo kubenza bafanelekele imijukujelwa kunye neegobolondo ze-artillery, ezibonakaliswa yinkqubo efana ne-Tomahawk cruise missile kunye ne-M982 Excalibur.
Umzobo womzekelo gimbaled inertial uzinzo iqonga usebenzisa ukunyuswa. Ngoncedo lobuNjineli 360.
