I-GE's Marine Solutions inika ingxelo yokuba igqibe ngempumelelo iintlobo ngeentlobo zeemvavanyo zomlilo kwindawo yayo entsha edibeneyo yaselwandle i-LM2500 njengenxalenye yeNkqubo yeModyuli yeModernization (MMP). Umlilo kunye nezinye iimvavanyo zecandelo ziqinisekisile ukusetyenziswa kwezinto ezidibeneyo ukunciphisa ngokuphawulekayo ubunzima kunye nokuphucula ukusebenza. Ukongeza, uyilo lwepakethe luye lwaqhubela phambili ukubandakanya iinzwa zepakethe ezihlaziyiweyo kunye namacandelo.
Abathathi-nxaxheba be-MMP baquka i-GE, i-General Dynamics Bath Iron Works kunye ne-United States Navy; inkqubo iqale ngowama-2014.
"Iinqanawa zihlala zicela umngeni ngobunzima ukuhlangabezana neemfuno zangoku kunye nezexesha elizayo kunye nokunciphisa iindleko zomjikelo wobomi," utshilo u-GE's Brien Bolsinger, uSekela Mongameli, uMphathi Jikelele. Yiyo loo nto i-MMP iyilwe ngeemfuno zabathengi: ukuhlaziya imodyuli ye-iturbine yegesi kunye nobuchwepheshe obutsha obuqinisekisiweyo obunciphisa ubunzima bendawo ebiyelweyo malunga ne-50%, ngelixa ikwanciphisa iindleko zomjikelo wobomi, ukuphuma kwengxolo kunye nokuphucula ukhuseleko.
Imodyuli entsha ye-monolithic ehlanganisiweyo ye-GE's LM2500 imodyuli yaselwandle ayisebenzisi i-bolted joints phakathi kweendonga kunye nesilingi. Olu phawu luphucula kakhulu ukudibanisa kunye nokuthomalalisa ingxolo ngokuphelisa imijelo yengxolo. Ukusetyenziswa kwee-composites kukwavumela ukuba iingcango zemodyuli kunye neepaneli zokufikelela zenziwe zibe nkulu, kodwa zibe khaphukhaphu ukuze kube lula ukuphatha. Ukusetyenziswa kwee-composites kuphelisa ukugqwala kweengcango, ii-hinges kunye neepaneli zokufikelela, ukunciphisa ukugcinwa ngelixa kuphucula ukhuseleko.
Kubonisiwe imodyuli entsha ye-GE LM2500 ye-injini yegesi yaselwandle ehlanganisiweyo esecaleni ngexesha lokuchasa kunye novavanyo lokuqinisekisa imfezeko yolwakhiwo olwenziwa kwi-Southwest Research Institute.
Uvavanyo lomlilo lwenziwa kwi-Southwest Research Institute (SwRI) ukuqinisekisa ukuba idizayini edibeneyo ihlangabezana neemfuno zokumelana nomlilo wase-US Navy. I-SwRI yilabhoratri yovavanyo evunyiweyo kunye ne-arhente yokuqinisekisa umgangatho kunye nokuhlola.
Uvavanyo lwe-SwRI lukwaveze oku kulandelayo:
• Udonga oludityanisiweyo lwemodyuli luphumelele iimvavanyo zelangatye elithe ngqo kunye nobushushu obungathanga ngqo, oluthi uvavanyo lukhuphe umsi kunye netyhefu yerhasi.
• Udonga oludibeneyo kunye nephaneli yesilingi iphumelele iimvavanyo zokuxhathisa umlilo kunye novavanyo lwemfezeko yesakhiwo. Ezi mvavanyo zilinganisa umthamo wezixhobo zokumelana nokunyuka komlilo okukhawulezayo kunye nokukwazi kwesakhiwo ukuthwala umthwalo (kubandakanywa nabasebenzi bokucima umlilo) ngexesha lesiganeko somlilo. Iphaneli yayiphantsi kokunyuka ngokukhawuleza kweqondo lokushisa kwaye ibanjwe kwi-2000oF.
• Uvavanyo kunye nohlalutyo lwentsimbi kunye namacandelo eludongeni oluhlanganisiweyo oluphantsi kwe-500oF - kunye nephakheji epheleleyo yohlalutyo lokutshintshwa kobushushu - lubonise ukuphuculwa okuphawulweyo kunye noyilo lwendonga ye-GE edibeneyo. Ezi mvavanyo zibonisa ukuba ubushushu bolusu lwangaphandle buya kuncitshiswa kakhulu.
• Iimvavanyo zothelekiso lwephaneli ye-acoustic zibonise ukuphucuka kumanqanaba oxinzelelo lwesandi esithunyelwayo (dBA).
I-MMP igxile kwindawo ebiyelweyo eyi-GE ejikeleze yonke i-injini yegesi ye-LM2500 (i-inlet, injini kunye ne-exhaust) eyenza imisebenzi emininzi ebalulekileyo. Indawo ebiyelweyo inqanda ukwala ubushushu kwigumbi lomatshini kwaye ibonelela ngokhuseleko lobushushu kubasebenzi ukusuka kumaqondo obushushu > 1000oF aphuma kwiinjini yegesi kunye nokuphuma. I-enclosure yenza i-acoustic kunye nomda womlilo ojikeleze i-turbine yegesi ukwenzela ukhuseleko lwenqanawa. Ngokusekwe kuvavanyo, i-LM2500 entsha ehlanganisiweyo edibeneyo iya kunciphisa ingxolo ngelixa igcina iimpawu ezifanayo zokuchasa umlilo njengentsimbi yentsimbi.
LM2500 imodyuli yaselwandle
Iqinisekiswe ngokupheleleyo kwiiMfuno zoMkhwa woMkhosi wase-US
Ukudityaniswa kwendawo ebiyelweyo yomfuziselo kuyaqhubeka ngoku kwaye kuya kuvavanywa kwisikali esipheleleyo sovavanyo lweseli yovavanyo lwe-iturbine yerhasi ukuqinisekisa ukuthomalalisa ingxolo kunye nokusebenza kobushushu okuxelwe kwangaphambili ngovavanyo lwamacandelo kunye nohlalutyo. Indawo ebiyelweyo ehlanganisiweyo iya kuthi ke iphantsi kovavanyo lokothuka kweenqanawa kwiimfuno zoMkhosi woMkhosi wase-US. Ezi mvavanyo zicwangciselwe ukuba zigqitywe phakathi ku-2018.
Imodyuli ye-injini yegesi ephuhliswe phantsi kwe-MMP iya kufumaneka ngo-2018 kunye nesicelo sokuqala esijoliswe kwi-US Navy ye-DDG-51 yeenqanawa ze-Flight III. I-enclosure edibeneyo edibeneyo kunye nezixhobo ezihlaziyiweyo ziya kufumaneka kwii-navies zamazwe ngamazwe kwi-2018, ngokunjalo. Ngokwahlukileyo, i-GE kungoku nje yenza indibano yocango oludityanisiweyo yokubuyisela umthengi womkhosi waselwandle.
Ehlabathini lonke, ngaphezu kwe-1,400 GE ii-turbines zegesi zingena kwiiyure ze-14 zezigidi ezikhonza iinqanawa ze-35 kwiinqanawa ze-500 kwiinqanawa ze-100 zeenqanawa zomkhosi ezivela kwiinqanawa zokujikeleza, ababhubhisi kunye nabahamba ngeenqanawa ukuya kwi-corvettes, i-frigates, iinqanawa ze-amphibious kunye nabathwali beenqwelo-moya.
