Northrop Grumman, ib tug ntawm cov tub rog loj hauv Teb Chaws Asmeskas, tau ua tiav kev sim lub cev muaj zog tshaj plaws rau US Navy, lub ntiaj teb thawj 36.5-megawatt (49,000-hp) high-temperature superconductor (HTS) nkoj propulsion electric motor, ob zaug sai li sai tau. US Navy lub zog ntsuas ntsuas cov ntaub ntawv.
Lub cev muaj zog siv cov coils ntawm high-temperature superconducting hlau, thiab nws lub peev xwm thauj khoom yog 150 npaug ntawm cov hlau zoo sib xws, uas yog tsawg dua li ib nrab ntawm cov pa motors.Qhov no yuav pab ua kom cov nkoj tshiab muaj roj ntau dua thiab tso chaw kom muaj peev xwm sib ntaus sib tua ntxiv.
Lub kaw lus tau tsim thiab tsim nyob rau hauv US Office of Naval Research daim ntawv cog lus los ua kom pom qhov ua tau zoo ntawm high-temperature superconducting motors ua tus thawj propulsion technology rau yav tom ntej Navy tag nrho cov hluav taws xob ships thiab submarines.Naval Sea Systems Command (NAVSEA) tau pab nyiaj thiab coj qhov kev sim ua tiav ntawm lub tshuab hluav taws xob.
US Navy tau nqis peev ntau dua $ 100 lab hauv kev txhim kho cov cuab yeej siv hluav taws xob kub siab tshaj plaws, ua rau txoj hauv kev tsis yog rau cov nkoj tub rog xwb, tab sis kuj muaj cov nkoj lag luam, xws li cov tsheb thauj khoom thiab cov roj liquefied natural gas (LNG) tankers, uas tuaj yeem siv qhov chaw. thiab cov txiaj ntsig kev ua tau zoo ntawm high-temperature superconducting xyaw.
Load tests qhia tau hais tias lub cev muaj zog coj li cas nyob rau hauv kev ntxhov siab thiab kev ua haujlwm thaum lub zog ntawm lub nkoj hauv hiav txwv.Cov theem kawg ntawm kev loj hlob ntawm lub cev muaj zog muab engineers thiab marine propulsion integrators nrog cov ntaub ntawv tseem ceeb ntawm cov kev xaiv tsim thiab kev khiav hauj lwm yam ntxwv ntawm tus tshiab superconductor lub cev muaj zog.
Qhov tseem ceeb, qhov kub-kub superconducting lub cev muaj zog tsim los ntawm AMSC tsis tau hloov pauv loj hauv cov ntsiab lus ntawm kev siv tshuab thev naus laus zis.Cov tshuab no ua haujlwm zoo ib yam li cov tshuab hluav taws xob zoo ib yam, tau txais lawv cov txiaj ntsig zoo los ntawm kev hloov tooj liab rotor coils nrog high-temperature superconducting rotor coils.HTS lub cev muaj zog rotors khiav "txias," zam lub thermal stresses uas cov motors ib txwm muaj thaum lub sijhawm ua haujlwm.
Qhov tsis muaj peev xwm ua kom tau raws li kev tswj xyuas thermal tau yog ib qho teeb meem tseem ceeb hauv kev tsim lub zog-dense, high-torque electric motors xav tau rau kev siv tub rog thiab kev lag luam marine.Nyob rau hauv lwm cov high-power motors, kev ntxhov siab tshwm sim los ntawm tshav kub feem ntau yuav tsum tau kim kho lub cev muaj zog thiab kho dua tshiab.
Lub 36.5 MW (49,000 hp) HTS lub cev muaj zog tig ntawm 120 rpm thiab tsim 2.9 lab Nm ntawm lub zog. Lub cev muaj zog tau tsim tshwj xeeb los txhawb lub zog tiam tom ntej ntawm kev ua rog hauv US Navy.Fais motors ntawm qhov loj me no kuj muaj kev lag luam ncaj qha siv rau cov nkoj loj loj thiab cov tub lag luam nkoj.Piv txwv li, ob lub 44 MW cov qauv siv tau siv los txhawb lub nkoj nto moo Elizabeth 2.Lub cev muaj zog hnyav dua 400 tons txhua, thiab 36.5-megawatt HTS lub cev muaj zog yuav hnyav li 75 tons.
