Title: Boeing B-17, Flying Fortress Post by: duje on July 29, 2012, 05:16:04 am Boeing B-17 Flying Fortress, koji je u sastavu zračnih snaga SAD služio tokom čitava drugog svjetskog rata, možda je najglasovitiji avion SAD u ratu. Njegov razvoj u prvoj polovini tridesetih godina pokazuje s kakvim su se elanom Amerikanci bavili pitanjima preciznog teškog bombardera u vrijeme kad se veći dio evropskih projekata bombarderskih aviona odnosio na kategoriju srednjih bombardera. B-17 je bio projektiran 1934. godine na osnovu zahtjeva što ga je u maju izdao Zrakoplovni korpus armije SAD tražeći projekt višemotornog bombardera koji će biti sposoban da teret najmanje 900kg prenese na udaljenosti od najmanje 1.640km brzinom od 322km/h ili više. Kako je kompanija radila na jednom drugom većem bombarderu, Modelu 294 ili XB-15, odluka da sudjeluje i u natječaju za novi avion bila je riskantna. Rad na nacrtu i konstrukciji napredovao je brzo i prototip Modela 299, kako je firma Boeing označila novi avion, prvi put je poletio u julu 1935. Taj se prototip ponekad pogrešno spominje kao XB-17. Za pogon su služila četri zvijezdasta motora Pratt & Whitney R-1690 Hornet po 750KS, defanzivno naoružanje sastojalo se od pet pojedinačnih mitraljeza od 7,62mm, a ponjeti je mogao teret od 2.177kg bombi. Iako je taj prototip bio uništen u udesu, njegove su performanse toliko obećavale da je USAAC naručio pretproizvodnu partiju od 14 aviona YB-17, koji je u decembru dobio novu oznaku Y1B-17. Prvi primjerak isporučen je u decembru 1936. sa zvijezdastim motorom Wright GR-1820 od 930KS. Prvih 13 aviona Y1B-17 bilo je dovršeno po tom standardu, dok je četrnaesti izgrađen kao jedini model Y1B-17A u toj pariji s motorima opskrbljenim turbokompresorom. S takvim motorima povećana je maksimalna brzina na 501k/h, a operativni plafon na 9.144m, pa su oni korišteni za sve daljnje modela B-17. Poslije izvršenih ispitivanja, model Y1B-17 dobio je novu oznaku B-17, a model Y1B-17A ozmaku B-17A. Kako je mornarica SAD stavila prigovor na avion kojim se pokušava prisvojiti njeno pravo da brani obale Amerike, planiran veliki broj aviona B-17 koje je USAAC namjeravao nabaviti morao je biti smanjen. Godine 1938. Naručen je prvi stvarno proizvodni model, B-17B koji je imao veće vertikalno kormilo, veće flapsove i modificiran nos aviona. Model B-17B izgrađen je u 39 primjeraka. Proizvodnja modela B-17C, kojih je bilo naručeno 38 komada, započela je 1939. godine. Taj je model mogao ponjeti veću težinu u polijetanju, poboljšani su mu motori i naoružanje. Poslije B-17C slijedila su u 1941. godini 42 aviona modela B-17D. Avion B-17D se samo neznatno razlikovao od svog prethodnika i bio je prva varijanta “leteće tvrđave” koja je u sastavu USAAF ušla u borbu. Veći broj tih aviona uništen je na zemlji prilikom iznenadnog japanskog napada na Havaje i Filipinsko otočja u decembri 1941. Sljedeći model koji je ušao u naoružanje bio je B-17E, znatno modificiran tip, pri čemu su korištena iskustva što su jih posade Kraljevskih zračnih snaga stekle u borbi. Godine 1941. dobio je RAF deset aviona B-17C, koji su u njegovu sastavu nosili naziv Fortress I, a iskustva u borbi pokazala su da je defanzivno naoružanje od jednog mitraljeza kaibra 7,62mm i šest kalibra 12,7mm sasvim nedovoljno. Prvi od 512 izgrađenih aviona B-17E isporučen je USAAF-u u oktorbru 1941, a karaktriziralo ga je potpuno revidirano defanzivno naoružanje i mnogo veće repne površine, čime je omogućeno bolje upravljanje avionom na velikim visinama. Naoružanje tog novog modela sastojalo se od kupola s po dva mitraljeza od 12,7mm na repu aviona, leđnom i trbušnom dijelu, te dva mitraljeza od 12,7mm na bokovima trupa i dva od 7,62mm u nosu. Teret bombi, koji je kod modela B-17 bio 4.761kg, povećan na 7.983kg za male udaljenosti. Iznenađuje što je B-17E, iako mu je ukupno opterećenje poraslo za 2.880kg, dok su mu za pogon još uvjek služili zvijezdasti motori Wright R-1820-65 od 1.200KS, kave je imao i model B-17C, postizao maksimalnu brzinu od 510km/h na visini od 7.620m, prema 468km/h prethodnog modela na istoj visini. B-17E uključen je u operacije na pacifičkom ratištu u decembru 1941, a na evropskom u julu 1941. Korišten je bio u prvom napadu Osme zrakoplovne armije SAD na Evropu 17. Augusta 1941. Međutim, u maju 1942. Pojavio se B-17F izgrađen na osnovi iskustva koja su B-17D stekli opreirajući na Pacifiku u mjesecima neposredno poslije japanskog napada na Pearl Harbor. Imao je nov, u jednom komadu odliven nos od “perspexa”, poboljšan motor R-1820-97, te ojačan stajni trap, što mu je omogučavao da se opterećenje u polijetanju od 24.494kg poveća na 29.484kg, a na kraju i na 32.659kg. Daljnji elementi su mu dodavani kasnije u toku proizvodnje, ili su mu jih dodavale jedinice prve borbene linije, a radilo se obično o zaštitnom oklopu, defanzivnom naoružanju i povećanju zapremine rezervoara za gorivo u krilima. Na kraju je, ponovnom ugradnjom nosača pod krilima, omogućeno tom modelu da ponese teret od 9.435kg bombi na vrlo kratke udaljenosti. Proizvodnja B-17F iznosila je u svemu 3.405 aviona. Međutim, uprkos svim modifikacijama, B-17F trpio je još uvjek teške gubitke nad Evropom, osobito od strane njemačkih lovaca , čiji su piloti otkrili da je nos slaba točka “leteće tvrđave”. U nastojanju da doskoči njemačkim frontalnim napadima, kojima je bio razlog slabo naoružanje u nosu aviona, firma Boeing je razvila model B-17G, koji je prvi put poletio u julu 1943. Taj je model imao kupolu ispod nosa aviona s parom mitraljeza od 12,7mm, kakva je bila korištena kod zadnjih aviona modela B-17F, a kasniji avioni serijske proizvodnje imali su poboljšan i turbokompresor, čime je povećan i operativni plafon za 1.524m, tj. na 10.668m. Jedinice prve borbene linije izvršile su i mnoge druge modifikacije. Prioizvodnja B-17G, zadnje varijante osnovnog modela B-17, iznosila je u svemu 8.680 aviona. Sveukupna proizvodnja tipa B-17 dosegla je brojku 12.731 aviona i “leteća tvrđava” je s velikim uspjehom služila kao standardni dnevni teški bombarder USAAF-a u Evropi, Jugoistočnoj Aziji i na sjeverozapadnom Pacifiku. Međutim, 1946. godine ostalo jih je još samo nekoliko stotina u službi. Glavni nedostatak B-17 bio što je po projektu taj model bio srednji bombarder, pa i ako je kasije u ratu mogao ponjeti vrlo veliki teret bombi, bilo je to samo na uštrb akcionog radijusa. Druga mana bila mu je što se i suviše lako zapalio kad bi bio pogođen neprijateljskom vatrom.

Са њих су скидали и моторе, ако остатак није био исправан. Јединица се звала KG-200, није служила за бомбардовање него за специјалне мисије. Има неколико извештаја америчких посада које су виделе да их прати непознати бомбардер ван формације, могуће да су са тим авионима скидали прецизно податке о висини и курсу. Иначе су кориштени и код нас. Геринг је изјавио да су их користили за инфилтрацију агената на Балкану после ослобођења.

Quote B-17 Flying Fortress of the 92nd Bomb Group fitted with Disney Bombs taxying at Podington. A 4500 lb Concrete Piercing rocket-assisted bunker buster bomb developed during WW2 by the Royal Navy to penetrate hardened concrete such as submarine pens, which could resist conventional free-fall bombs. Devised by Royal Navy Captain Edward Terrell, the bomb was fitted with solid-fuel rockets to accelerate its descent, giving it an impact speed of 990 mph (1,590 km/h) — substantially beyond the 750 mph (1,210 km/h) free-fall impact velocity[5] of the 5 tonne Tallboy "earthquake" bomb for comparable purposes. The Disney could penetrate 16 ft (4.9 m) of solid concrete before detonating. The name is attributed to a propaganda film produced by the Walt Disney Studios, that provided the inspiration for the design.

Švedska je pre rata razvijala svoju civilnu avijaciju,proširivanjem ruta čak do SAD.To se nije ostvarilo pa su nastavili pregovore i za vreme rata.Medjutim početkom rata mogućnosti su postale veoma ograničene,pa su leteli gde su mogli.Tokom 1942g Švedska je održavala kurirsku avio liniju sa Škotskom ,to sa nekoliko DC 3 obojenih narandžasto.On je za to bio spor i uvek je bilo straha da će biti oboren.To se i dogodilo pa su dva izgubljena. Jednog je oborio (Douglas DC-3-268 ,SE-BAG) oktobra 1943g ,gde je poginulo 13 putnika,noćni lovac Junkers Ju 88. Jedan oštećen je nekako došao do okoline Stoholma i prinudno sleteo. Tokom 1943g je osnovana avio kompanija -"Svensk Interkontinental Lufttrafik AB" (SILA),kao privatna firma,koja je oslobodjena politike i uticaja vlade.Dobili su prava za prevoz u SAD,i odmah je naručeno deset Douglas DC4.Ali,biće isporučeni kad se rat završi.U firmi SILA se razmišlalo šta da se radi. Kada su SAD krenule da lete iznad Evrope,ošećeni avioni su sletali ,ako mogu, tamo gde će biti bezbedni.Tako je ,po nekim podacima,bilo oko 70 avijatičara koji su se našli u neutralnoj Švedskoj.Avioni i avijatičari su zarobljeni.Vojska SAD je tražila da vrate ljude,koji su im bili preko potrebni,ali i avione.Švedjani su se dosetili pa su pregovarali sa SAD da uzmu avione u zamenu za avijatičare.Dogovoreno je da firmi SILA prodaju 10 aviona B 17 ,za 1 dolar ali da vrate ljude. Ipak do kraja rata nije bilo letova iz Švedske do SAD.Leteli su iz Škotske,od oktobra 1944g,do avgusta 1947g.Igrom slučaja jedan od njih je preživeo do danas,pa je vraćen u predjašnje sanje. Na kraju dobili su devet aviona,tri su ostavili za delove a ostale su prebacili u fabrike SAAB-a.Pretvaranje aviona u putnički je zahtevalo sklanjanje svu vojnu opremu,stavljanje švedske letačke opreme(radio uredjaji,tabla sa instrumentima po svedskom standardu),pilotskakabina promenjena za dva pilota,radistu i navigatora ,produženje nosa aviona( zbog centraže,jer je rep koriščen za tovarni prostor 1,8m³),pretvaranje dela za bombe u prostor za stvari(dizalica za bombe je iskorišćena za podizanje torbi).Unutrašnost podeljena na dve putnikče kabine i mali toalet u repu.Prva je imala osam sedišta,a druga sa svake strane kabine po tri udobne fotelje .Sa strane ,na trupu,napravljeni su novi prozori.Ulaz je paravljen na desnoj strani trupa.Kabine su bile zvučno izolovane i grajale su se.Obojeni su kamuflađnom bojom spolja(verovatno zelenom) sa velikim žutim natpisom sa starne na trupu "Sweden" [attachment=1] Posao je tajao 6 meseci,(prva tri završena u septembru,a ostali u novembru)a avion je označen kao F -17(navodno po Felix Hardeson,američki vojni ataše u Švedskoj).Ceo posao je koštao 50000 dolara. Prvi let je obavljen u oktobru 1944g za Prestwick,i to se nastavilo do krajarata.Nakon rata su leteli za Now York.Evropu,Afriku i južnu Ameriku,sve do avgusta 1947g,kada su stigli DC 4.Posle su neki prodati drugim zemljama. [attachment=2] Jedan od prvih prepravljenih u Švedskoj [attachment=3] Danska je sa nekima od njih letela do 1961g.Jedan je prodat French Institut Géographique National ,gde je leteo za potrebe snimanja zemlje iz vazduha.Pri zadnjem sletanju je oštećen ,pa je gurnut na kraj aerodroma.Otkriven je od istoričara vazduhoplovstva 1968g,pa je prenet u SAD,gde je obnovljen i vraćen u prvobitno stanje.Za razliku od drugih B 17 koji su obnovljeni,ovaj je bio u akcijama za vreme rata.

среда, 02.10.2019. ХАРТФОРД - Најмање пет људи погинуло је у паду бомбардера из времена Другог светског рата у близини Међународног аеродрома Бредли, северно од Хартфорда у америчкој држави Конектикат, саопштили су званичници. https://youtu.be/--nM8EnQcHI Авион Б-17 са четири мотора, у којем је било 13 путника, срушио се и запалио приликом неуспешног покушаја узлетања, док је пилот настојао да га поново приземљи, преноси АП. „Летелица је у ваздуху била неколико минута, када је пилот пријавио проблем са достизањем висине”, рекли су званичници, преноси Танјуг. Авион Б-17 на аеродрому је раније ове недеље изложила едукативна група Колингс фондација. Само неколико оваквих авиона је у техничком стању да могу да лете. Авиони дуги 23 метра, са распоном крила 32 метра, коришћени су у дневним бомбардовањима Немачке током Другог светског рата. То су биле изузетно ризичне мисије које су помогле да се разбије нацистичка ратна машина, наводи АП. Колингс фондација је саопштила да се исти авион срушио на аеро-митингу у близини Питсбурга 1987. године, када је повређено неколико људи.

Title: Re: Boeing B-17, Flying Fortress Post by: Dreadnought on April 19, 2021, 09:09:34 am Quote The Swoose - B-17 Flying Fortress with an Unusual Tail The Swoose is one of the most iconic aircraft of World War 2. Originally called Ole Betsy, this B-17D Flying Fortress aircraft was part of the team that flew the first U.S. bomber mission during the war. The B-17 received its official nickname, The Swoose, when Australian repairmen changed its tail to a smaller shark-shaped fin. The tail reminded Captain Weldon Smith of a popular song about a tormented animal that was half-swan and half-goose But no one was quite as smitten with The Swoose as Colonel Frank Kurtz. The personal pilot of Lieutenant General George Brett, commander of the Allied Air Forces in Australia, became fascinated with the aircraft and even named his child after the plane. Together they carried out many air combat missions, but Kurtz was determined to make history and set off to break a few records... https://youtu.be/E30tfJ-yskQ Title: Re: Boeing B-17, Flying Fortress Post by: Dreadnought on April 25, 2021, 09:56:23 am Quote The Outrageous Custom Modified B-17 with 16 .50 Caliber Machine Guns In 1943, a B-17 Flying Fortress laid low in a boneyard, ready to be torn apart for scraps. The aircraft came with a questionable reputation, having suffered heavy damage during its warfare missions. Many believed this was due to its ominous tail number, 41-2666. But the aircraft was salvaged by a group of nine so-called military renegades led by pilot Jay Zeamer. Renamed as Old 666, the misfits put so many weapons on the aircraft that it looked almost comical, and the plane became the most heavily-armed bomber in the Pacific. During one dangerous operation over New Guinea, the heavily-armored B-17 put all its weaponry to good use, taking part in one of the most decorated missions in American military history… https://youtu.be/rEXdcr_8U3s Title: Re: Boeing B-17, Flying Fortress Post by: Dreadnought on September 26, 2021, 02:57:20 pm Quote The B-17 that Landed with No One On Board On the early morning of November 23, 1944, a Royal Air Force antiaircraft unit stationed in the outskirts of Cortonburg, Belgium, spotted a 35,000-pound B-17 Flying Fortress flying towards them. As the unscheduled aircraft continued to approach at high speed with its landing gears down, the base's personnel assumed it was an emergency landing. Prepared for the worst, everyone watched as the B-17 uncontrollably landed in a nearby field. The soldiers waited for the crew to come out, but no one did. Major John V. Crisp then came on board and found no traces of human presence. The legend of the Ghost Bomber had begun. https://youtu.be/EN-2He70Aek |
