Wajiga cusub ee Sigma
Wajiga cusub ee Sigma
18-kii Janaayo ee sanadkan, markabkii ugu horreeyay ee SIGMA 10514 ee Tentara Nasional Indonesia-Angkatan Laut (TNI-AL, Indonesian Navy) ayaa laga bilaabay goobta PT PAL ee gobolka Surabey. Markabkan oo lagu magacaabo Raden Eddy Martadinata, waa xubintii ugu dambaysay ee qoys guulaysata oo maraakiib ah oo ay nashqadeeyeen kooxda dhisamaha maraakiibta Nederland ee Damen. Way adag tahay in lagu caajiso, sababtoo ah ilaa hadda nooc kasta oo cusub wuu ka duwan yahay kuwii hore. Tani waxay sabab u tahay isticmaalka fikradda moodeelka ah ee kuu ogolaanaya inaad abuurto nooc cusub oo markabka ah oo ku salaysan cutubyo la xaqiijiyay, iyada oo la tixgelinayo baahiyaha gaarka ah ee isticmaalaha mustaqbalka.
Fikradda halbeegga joomatari ee SIGMA (Ship Integrated Geometrical Modularity Approach) ayaa horayba si fiican noogu naqaannay, marka waxaan si kooban u xasuusannaa mabaadi'deeda.
Fikradda SIGMA waxay yaraynaysaa wakhtiga loo baahan yahay si loo naqshadeeyo markab dagaal yar iyo mid dhexdhexaad ah ujeeddooyin badan leh - corvette ama class frigate - kaas oo markaa si fiican ula qabsan kara baahiyaha kala duwan ee qandaraaslayaasha kala duwan. Habayntu waxay inta badan khusaysaa kiisaska, kuwaas oo laga sameeyay qaybo cabbir iyo qaabab la bixiyay. Qaabkoodu wuxuu ku salaysan yahay Mashruuca Barakacin Xawaaraha Sare ee ay soo saartay Machadka Cilmi-baarista Badda Holland MARIN ee 70-meeyadii. Waxaa si joogto ah loo hagaajiyay oo la tijaabiyay inta lagu guda jiro imtixaannada moodeelka ee soo-jiidashada xiga ee maraakiibta heerka SIGMA. Naqshadaynta unug kasta oo soo socota waxay ku salaysan tahay isticmaalka baloogyada hull ee ballaciisu yahay 13 ama 14 m iyo masaafada u dhaxaysa madaxyada waaweyn ee aan biyuhu lahayn ee 7,2 m (submarine). Tani waxay ka dhigan tahay in qolofyada kala duwanaansho shakhsiyadeed ee noocyo taxane ah ay leeyihiin, tusaale ahaan, qaybo hore iyo gadaal, dhererkuna wuu ka duwan yahay iyadoo lagu darayo qaybo badan. Soo saaraha ayaa bixiya maraakiib leh dhererka 6 ilaa 52 m (laga bilaabo 105 ilaa 7 bulkheads), ballac ah 14 ilaa 8,4 m iyo barakaca 13,8 ilaa 520 tan - taas oo ah, maraakiibta ilaalada, iyada oo loo marayo corvettes ilaa maraakiibta iftiinka.
Habaynta sidoo kale waxa ka mid ahaa qalabyada gudaha, jimicsiga, qalabka elegtarooniga ah, oo ay ku jiraan hagidda, nidaamyada amniga iyo hubka. Sidan oo kale - sabab ahaan - isticmaalaha cusubi wuxuu u habeyn karaa cutubka si waafaqsan baahidiisa, isaga oo aan u baahnayn in uu naqshadeeyo. Habkani kaliya ma dhalinayo gaabintii aan soo sheegnay ee wakhtiga bixinta, laakiin sidoo kale hoos u dhigista khatarta farsamada ee mashruuca iyo, sidaas awgeed, qiimo tartan ah.
Maraakiibtii ugu horeysay ee fasalka SIGMA waxaa soo iibsaday Indonesia. Kuwani waxay ahaayeen afar mashruuc 9113 corvettes, i.e. cutubyada 91 m dheer iyo 13 m, oo leh barokaca 1700 oo tan. Qandaraasku wuxuu noqday kii ugu dambeeyay ee July 2004, dhismaha prototype wuxuu bilaabmay March 24, 2005, iyo markabkii ugu dambeeyay ayaa la ansixiyay. Maarso 7. 2009, taas oo macnaheedu yahay in taxanaha oo dhan la abuuray afar sano gudahood. Natiijo xitaa ka sii wanaagsan ayaa lagu helay dalab kale - laba corvettes SIGMA 9813 iyo markabka fudud ee SIGMA 10513 ee Morocco. Hirgelinta qandaraaskii 2008 waxay qaadatay wax ka yar saddex sano iyo badh laga bilaabo bilawga dhismaha ugu horreeya ee saddexda qaybood.
