Chinook ali moyo mpaka kalekale?
Mapulani a Boeing ndi dipatimenti ya chitetezo ku US zaka zingapo zapitazo adafuna kuti CH-47F Block II ikhale msana wa zombo zonyamula zankhondo zaku US mpaka pakati pazaka za zana lino.
Pa Marichi 28, helikopita yoyamba yonyamula katundu ya Boeing CH-47F Chinook Block II idanyamuka pabwalo la ndege la kampaniyo ku Philadelphia paulendo wake woyamba, womwe uyenera kukhala gulu lankhondo lankhondo la US ndi ogwirizana nawo mpaka zaka za m'ma 60 zazaka za zana la XNUMX. . . Pokhapokha, ndithudi, pulogalamu ya chitukuko chake ndi kupanga misala sikulephereka komanso kuchepetsedwa ndi zisankho za ndale, zomwe zakhala zikuchitika mu zenizeni za America posachedwa.
Pambuyo pa mayesero oyambirira, galimotoyo iyenera kuperekedwa kumalo oyesa fakitale ku Mesa, Arizona, kumene kufufuza ndi chitukuko chidzapitirira, kuphatikizapo kutenga nawo mbali kwa oimira Dipatimenti ya Chitetezo. M'miyezi ikubwerayi, ma helikoputala ena atatu oyesera adzawonjezedwa pamayeserowo, kuphatikiza imodzi mwazomwe zimathandizira magulu apadera.
MN-47G. Malingana ndi ndondomeko zamakono, rotorcraft yoyamba yopanga Block II iyenera kulowa mu 2023 ndikukhala mtundu wapadera wa MH-47G. Ndizodabwitsa kuti ndege yoyamba idapangidwa pogwiritsa ntchito ma rotor apamwamba, osati ma ACRB apamwamba. Chotsatiracho, chomwe Boeing wakhala akugwira ntchito kwa zaka zingapo, adapangidwa kuti awonjezere mphamvu zogwirira ntchito za rotorcraft - chifukwa cha iwo okha, mphamvu yonyamulira m'madera otentha ndi okwera kwambiri iyenera kuwonjezeka ndi 700÷900 kg.
Chimodzi mwa zifukwa zopangira Block II chinali chosatheka kuyimitsa JLTV pansi pa fuselage ya CH-47F Block I, yomwe HMMWV ndiyo malire a katundu.
Pulogalamu yomanga helikopita ya CH-47F Chinook idayamba m'zaka za m'ma 90, choyimira choyamba chinawuluka mu 2001, ndipo kutumiza kwa magalimoto opanga kunayamba mu 2006.
ing yapereka ma rotorcraft opitilira 500 amtunduwu kwa Asitikali ankhondo aku US ndi US Special Operations Command (ena mwa iwo opangidwa ndi kukonzanso ma CH-47D ndi zotumphukira) ndi gulu lomwe likukula la ogwiritsa ntchito kunja. Pakali pano, gulu lawo likuphatikizapo mayiko 12 padziko lonse, amene analamula okwana makope 160 (komanso mu nkhani iyi, ena a iwo akumangidwa ndi kumanganso CH-47D - iyi ndi njira anatengedwa ndi Spaniards ndi Dutch. ). Mwayi wogulitsa zambiri udakali wochuluka pamene Boeing ikuchita ntchito zotsatsa kwambiri zokhudzana ndi kugulitsa ma helikopita kwa ogwiritsa ntchito a Chinook omwe alipo, komanso m'mayiko omwe CH-47 sinagwiritsidwepo kale. Israel ndi Germany amaonedwa ngati angalonjeza makontrakitala (Chinooki sagwiritsidwa ntchito m'mayikowa, ndipo muzochitika zonsezi CH-47F imapikisana ndi Sikorsky CH-53K King Stallion helicopter), Greece ndi Indonesia. Boeing pano akuyerekeza kufunika kwapadziko lonse kwa ma Chinooks osachepera 150 kuti agulitsidwe pofika 2022, koma mapangano okha omwe ali kale omwe amachititsa kuti msonkhanowu ukhale wamoyo mpaka kumapeto kwa 2021. Mgwirizano wazaka zambiri womwe udasainidwa pakati pa Dipatimenti ya Chitetezo ndi Boeing mu Julayi 2018
njira zingapo zotumizira ma helikopita a CH-47F Block I kudzera pa FMS, zomwe zimatha kupangidwa kumapeto kwa 2022, koma mpaka pano palibe ogula. Izi zitha kukhala zovuta kwa wopanga, chifukwa zitha kutanthauza kuti azisunga mzere wa msonkhano mpaka pulogalamu ya Block II italipidwa mokwanira komanso mgwirizano wanthawi yayitali wokonzekeranso pafupifupi 542 CH-47F / G ya asitikali aku US molingana ndi izi. . Ntchito izi zidzachitika mu 2023-2040, ndipo makasitomala omwe angathe kutumizidwa kunja ayenera kuwonjezeredwa ku chiwerengerochi.
Chifukwa chiyani Block II idakhazikitsidwa? Izi zinali zotsatira za maphunziro omwe tinaphunzira kuchokera ku nkhondo zankhondo ndi ntchito zothandiza anthu zomwe asilikali a US atenga nawo mbali m'zaka za zana lino. Ziwerengero za Unduna wa Zachitetezo ndizosasinthika - pafupifupi, chaka chilichonse kulemera kwa ma helikopita a banja la CH-47 kumakula ndi pafupifupi 45 kg. Izi, zimayambitsa kuchepa kwa mphamvu zonyamulira, motero, kuthekera konyamula katundu ndi anthu. Kuphatikiza apo, kulemera kwa zida zonyamulidwa ndi asitikali kudzera mumlengalenga kukuwonjezekanso. Kuonjezera apo, nkhani zachuma ndizofunikira kwambiri - kuwonjezereka kwa ndalama zogwirira ntchito komanso kuwonjezeka kwa nthawi yoyendera ndi kukonza, makamaka pazochitika za nthawi yayitali (mwachitsanzo, ku Afghanistan kapena Iraq). Kuwunika kwazinthu zonsezi kunapangitsa Pentagon kuvomereza (ndipo makamaka ndalama) ntchito yomwe ikufuna kupanga mtundu watsopano wa asilikali a US Army ndi galimoto yofunikira ya SOCOM, i.e. CH-47F Chinook Block II. Ndalama zoyamba zidasamutsidwa mu Marichi 2013. Kenako Boeing adalandira madola 17,9 miliyoni. Mgwirizano waukulu udasainidwa pa Julayi 27, 2018 ndipo ndi $ 276,6 miliyoni. Chilimwe chatha, US Special Operations Command idawonjezeranso $29 miliyoni.
Mawu a pulogalamuyi ndi "Kuthekera komanso kutsika mtengo wogwirira ntchito". Kuti izi zitheke, opanga Boeing, mogwirizana ndi Unduna wa Zachitetezo, adaganiza zopanga gawo lotsatira la kulumikizana kwa zida pakati pa "basic" CH-47F ndi "zapadera" MH-47G, komanso kugwiritsa ntchito zochitika zaku Canada. Choyamba, tikukamba za kufunikira koonjezera mphamvu yonyamulira kumalo otentha komanso okwera kwambiri. Boeing akuti mtundu watsopanowu udzawonjezera kuchuluka kwa ndalama zolipirira pafupifupi 2000kg, kupitilira zomwe dipatimenti ya Chitetezo imafunikira 900kg, kuphatikiza 700kg pamalo okwera komanso otentha.
