British frigates ntawm Cold War. Turbocouple cov muam
Ib qho kev txuas ntxiv ntawm Hom 41 thiab Hom 61 frigates tshwj xeeb hauv Hiav Txwv thiab Nkoj Tshwj Xeeb Qhov Teeb Meem 3/2016 yog ob qhov ntxiv ntawm Royal Navy escort units, hu ua cov hloov kho hom 12 thiab 12, nrog kev txhim kho hydrodynamics, propulsion thiab khoom siv.
Rau cov kev tshawb fawb ntawm British project ntawm PDO blocks, ua nyob rau hauv lub thib ob ib nrab ntawm lub 40s, lub "piv txwv" lub hom phiaj yog submarines muaj peev xwm tsim ib tug ceev ntawm txog 18 knots nyob rau hauv ib tug submerged txoj hauj lwm, nrog rau ib txhij kev xav tias nws yuav sai sai no. Yog li ntawd, Admiralty xav kom rov tsim cov frigates muaj peev xwm ntawm qhov siab tshaj plaws ntawm 25 knots nrog lub zog cog ntawm 25 20 km thiab thaj tsam ntawm 000 3000 nautical mais ntawm qhov ceev ntawm 15 knots. Thaum xaus ntawm xyoo 1947, thaum pib ntawm lub xyoo tshiab, muaj kev hloov pauv tseem ceeb hauv txoj hauv kev ntawm Royal Navy rau qhov teeb meem PDO. Raws li nws cov lus qhia zaum kawg, escort ships yuav tsum ncav cuag speeds 10 knots sai dua tus yeeb ncuab submarines. Los ntawm no, tom qab kev soj ntsuam, nws tau pom tias 27 knots yuav zoo rau "tus neeg yos hav zoov tshiab" lwm qhov kev xav tau tseem ceeb ntawm Admiralty yog qhov teeb meem ntawm kev ya davhlau, tus nqi tau nce los ntawm yav dhau los 3000 mus rau tsawg kawg 4500 nautical mais. nyob rau tib lub economic ceev. Nws sai sai tau pom tseeb tias txoj kev loj hlob ntawm lub zog turbine propulsion system uas ntawm ib sab yog lub teeb thiab compact, thiab ntawm qhov tod tes, tuaj yeem tsim lub zog xav tau los ua kom tiav 27 watts thaum tswj cov roj noj uas tso cai rau 4500 hli ntawm kev mus ncig, yuav. tsis yooj yim li ntawd. Txhawm rau ua kom cov kev xav tau no muaj tseeb, Admiralty thaum kawg tau pom zoo txwv qhov kev lag luam nrawm rau 12 pob (qhov qis tshaj tso cai rau kev thauj mus los ntawm 10 pob).
Thaum pib, kev ua haujlwm ntawm PDO tshiab tau ua tiav qeeb heev, vim tias qhov tseem ceeb tshaj plaws tau muab los hloov lub ntiaj teb Tsov Rog Zaum II rau hauv lub luag haujlwm frigate. Tus qauv tsim tau npaj txhij rau lub Ob Hlis 1950. Kev ua haujlwm ntawm cov frigates tshiab tsis tau pib txog thaum pib ntawm kev thaiv ntawm West Berlin, uas tshwm sim hmo ntuj ntawm Lub Rau Hli 23-24, 1948. Hauv lawv txoj haujlwm, nws tau txiav txim siab siv cov ntsiab lus qiv los ntawm yav dhau los piav txog hom 41/61 frigates, incl. low superstructure, artillery nyob rau hauv daim ntawv ntawm ib tug ob lub rooj Mk V universal phom nyob rau hauv ib tug 114 hli Mk VI turret (tswj los ntawm lub Mk 6M hluav taws tswj system), raws li zoo raws li 2 Mk 10 Limbo mortars ntsia nyob rau hauv lub aft "zoo". Cov khoom siv radar yuav tsum muaj hom 277Q thiab 293Q radars. Tom qab ntawd, ob hom 262 (rau kev tiv thaiv dav hlau hluav taws xob ntawm qhov luv luv) thiab hom 275 (rau kev tiv thaiv dav hlau hluav taws ntawm qhov deb) tau ntxiv rau lawv. Sonar hom 162, 170 thiab 174 (tom qab ntawd tau hloov los ntawm hom tshiab 177) yuav tsum muab tso rau hauv cov khoom siv sonar. Nws kuj tau txiav txim siab los nruab torpedo riam phom. Thaum xub thawj, lawv yuav tsum muaj 4 ib qho txuas mus tas li launchers nrog rau 12 lub torpedoes. Tom qab ntawd, cov kev cai no tau hloov mus rau 12 chav, ntawm 8 (4 ib lub rooj tsav xwm yuav tsum yog cov chaw nres tsheb), thiab lwm qhov 4, hauv 2xII system, teb.
Kev siv cov turbo-steam fais fab nroj tsuag tshiab rau propulsion muaj kev cuam tshuam tsis zoo rau qhov hnyav thiab qhov sib cais loj. Yuav kom tsim tau nws, lub hull yuav tsum tau nthuav dav, tom qab ntau qhov kev ntsuam xyuas, nws qhov ntev tau nce los ntawm 9,1 m thiab qhov dav los ntawm 0,5 m. Qhov kev hloov no, txawm hais tias thawj zaug thuam rau kev ntshai ntawm kev nce nqi, tau dhau los ua ib qho kev hloov pauv. Kev txav mus los zoo heev, raws li kev ntsuas lub pas dej da dej tau pom tias qhov ntev ntawm lub hull txhim kho lub laminar ntws ntawm cov dej, ntxiv rau qhov ua tiav qhov nrawm ("ntev ntev"). Tus tsav tshiab kuj tau ua rau nws tsim nyog rau nruab ib lub chimney classic es tsis txhob siv lub tshuab hluav taws xob tsis zoo. Lub chimney npaj tau tsim los tiv thaiv lub moj tej tawg ntawm atomic blast. Thaum kawg, txawm li cas los xij, kev ua tau zoo yog qhov tseem ceeb tshaj qhov xav tau ntau dhau, uas yog qhov yuam kom nws rov tsim dua. Nws tau lengthened thiab qaij ntau dua rov qab. Cov kev hloov pauv no tau ua rau muaj txiaj ntsig zoo, vim tias cov huab cua ntawm lub tsev raug tso tseg, uas ua rau muaj txiaj ntsig zoo rau kev ua haujlwm ntawm cov neeg saib xyuas.
