Francesco Mattesini Posted April 10, 2017 Author Report Share Posted April 10, 2017 Le prime due foto sono esatte, in quanto al piroscafo BALTISTAN manca l'antenna del radar sopra il ponte di comando, che invece si vede benissimo nella terza foto.

Giuseppe Garufi Posted April 10, 2017 Report Share Posted April 10, 2017 P.S. Grazie, Giuseppe, e complimenti per l'acume di ricercatore... Come si diceva ? Vedo lontano perché sto seduto sulle spalle di Giganti. Quote Link to comment Share on other sites More sharing options...
Francesco De Domenico Posted April 10, 2017 Report Share Posted April 10, 2017 Quindi citando Tynebuiltships la foto si può mettere. Devi scrivere foto Clive Ketley, da tynebuiltships.co.uk Quote Link to comment Share on other sites More sharing options...

Admiral Canoga Posted April 14, 2017 Report Share Posted April 14, 2017 (edited) Buonasera Dottor Mattesini. L'acronimo UZO significa Uboot-Zieloptik. Si veda di Eberhard Rossler - The U Boat, the evolution and technical history of German submarines, Cassell, Londra 2001, pagine 236 e 374 (glossario). Oppure, su questi noti siti web:http://www.deutsche-unterseeboote.de/php/glossar/u-boot-glossar.php?pageNum_Recordset1=3&totalRows_Recordset1=157http://uboat.net/forums/read.php?20,84850,84851,quote=1 Mi permetto di segnalarLe questa tesi di David Habersham Wright della Georgia Southern University: http://digitalcommons.georgiasouthern.edu/etd/599/http://digitalcommons.georgiasouthern.edu/cgi/viewcontent.cgi?article=1599&context=etd In particolare alle pagine 35-36: "Attacks from the surface were always conducted from the bridge, normally by the executive officer (known as the First Watch Officer or 1WO) rather than the captain.The 1WO would use a special sighting instrument mounted on the bridge known as the Uboot-Zieloptik or UZO (U-boat targeting optical sight).Attacks while submerged, which normally occurred during the day, were made by the captain from the control center located in the conning tower by means of the attack periscope, which was different from the normal observation periscope.Both the UZO and the attack periscope would be used to calculate the target’s speed, estimated range, target angle on the bow, torpedo speed, and a correction factor for the target’s rate swing.These calculations would be called out to the executive officer, who would plug them into the targeting computer, known as the Vorhaltsrechner.This would calculate the torpedo’s proper direction angle, point of convergence, shot angle, and maximum range, the data being sent down to the torpedo room where the chief torpedoman would plug them into the gyro."

Francesco Mattesini Posted April 14, 2017 Author Report Share Posted April 14, 2017 Grazie Signor Ammiraglio. Quello che riporta é molto interessante e mi sarà utile. Può trovare il Saggio sull'attacco ai convogli a sud dell'Islanda, e quello sull'attività dei sommergibili italiani nell'America centrale tra il febbraio e l'aprile 1942, nella mia paguina di Accademia UDU: https://independent.academia.edu/FrancescoMattesini Cordiali saluti Francesco Mattesini Quote Link to comment Share on other sites More sharing options...
Admiral Canoga Posted April 15, 2017 Report Share Posted April 15, 2017 Grazie Dottor Mattesini per avermi segnalato la Sua pagina su Academia.edu: alcuni dei Suoi studi non li conoscevo ed è sempre un piacere leggerLa. Posso distrubarLa privatamente? Avrei alcune domande su Alberto Santoni e non solo. Cordiali saluti e Buona Pasqua. Admiral Canoga Quote Link to comment Share on other sites More sharing options...
Francesco Mattesini Posted April 16, 2017 Author Report Share Posted April 16, 2017 Signor Ammiraglio Sarà un piacere. Può farlo in posta elettronica e se vuole anche per telefono: 0677591781. Cordiali Saluti Francesco Mattesini Quote Link to comment Share on other sites More sharing options...
Francesco De Domenico Posted April 17, 2017 Report Share Posted April 17, 2017 Caro Francesco, ho il libro di Rossler (in tedesco, però...). Se ti serve .. Quote Link to comment Share on other sites More sharing options...
Francesco Mattesini Posted April 18, 2017 Author Report Share Posted April 18, 2017 Caro Francesco, sarei curioso di leggerlo, ma non conosco il tedesco. Comunque potrei dargli uno sbarco. Se passi da me potresti riprenderti l'altro libro. Ciao Franco Quote Link to comment Share on other sites More sharing options...
Admiral Canoga Posted April 18, 2017 Report Share Posted April 18, 2017 Dottor Mattesini mi permetto di segnalarLe alcuni siti web ove è possibile consultare un po' di documentazione, soprattutto fotografica, sulle centraline UZO. Partiamo dalle pagine che questo ottimo sito web di un collezionista italiano dedica ai binocoli Zeiss: http://www.historicacollectibles.com/it/binoculars-amp-telescopes/pagina2http://www.historicacollectibles.com/it/binoculars-amp-telescopes/binocolo-7x50-blc-zeiss-udf-uzo-u-boot-kriegsmarinehttp://www.historicacollectibles.com/it/binoculars-amp-telescopes/binocolo-7x50-blc-carl-zeiss-udf-uzo-reichsadler-u-boot-kriegsmarine-circa-1943http://www.historicacollectibles.com/it/binoculars-amp-telescopes/binocolo-7x50-blc-carl-zeisshttp://www.historicacollectibles.com/it/binoculars-amp-telescopes/binocolo-7x50-blc-carl-zeiss-udf-uzo-con-rarissimi-tubi-parapioggia-u-boot-kriegsmarine-circa-1943http://www.historicacollectibles.com/it/binoculars-amp-telescopes/binocolo-7x50-blc-zeiss-udf-uzo-u-boot-kriegsmarine-con-mirino Questo è il sito internet dedicato al sommergibile museo U-995 (un Tipo VII-C/41). Si faccia attenzione alla prima, alla terza e alla tredicesima fotografia: http://www.u-995.com/brueckenwanne.html Segnalo anche il sito web di Anna e Terry Vacani ( http://binoculars-cinecollectors.com/) ove sono reperibili questi documenti pdf dedicati alle ottiche dei sommergibili: - http://www.binoculars-cinecollectors.com/U-boat_binoculars_and_other_items1.pdf In particolare a pagine 16: "Large binoculars mounted on the deck" On the German U-boats deck was mounted a pedestal mount with a clamping device, in the center for a large heavy binocular. This was the base for UZO (U-Boot-Zieloptik = U-Boat aiming optic) torpedo aiming device.Researches of the war time films and the published books and magazines, often show these models;8 x 60 and U.D.F.7 x 50 UDF was watertight to about 100 meters of diving; over this depth the glasses would be damaged. Usually the binocular was not left on deck when the U-boat was submerged; only in an emergency dive it was left on deck. - http://www.binoculars-cinecollectors.com/U.D.F._by_Anna_and_Terry_Vacani_encr_.pdf In particolare a pagina 5: As it was explained in the book mentioned above; the conning tower (Turm) was theobservation tower or platform of submarine; on a U-boat it contained steering controls; on type IX U-boats it contained the attack periscope eyepieces and torpedo deflectioncalculator.Below the conning tower and bridge was located the control room over headed, betweentwo periscopes, were a watertight hatch and a ladder giving access to the coning tower.Once a target had been sighted, in any firing solution could only be obtained by using one ofthe two available sighting devices: by periscope or by UZO–Uberwasserzieloptik.As we read in “U-boat Type VII” by Robert C. Stern:“The UZO was located toward the front of the external tower, between the hatch and thesky periscope. It was composed of two parts: a pair of large rangefinder binoculars (amongthem UDF); and a permanently mounted rotating bracket set in a ring marked off in degrees.The binoculars [...] were mounted on the rotating bracket only when actually needed forsurface attack computation. They had to be taken inside the boat before diving becausethey weren’t waterproof at depth. Both the attack periscope and the UZO were linked to a mechanical analog attack computer located at the after end in the conning tower. [ ] When the target was properly lined up, the necessary mechanical connections weremade to the gyro compass and the UZO or attack periscope” Si presti attenzione: qui Robert C Stern indica l'acronimo UZO con Uberwasserzieloptik. Dottor Mattesini cercherò di consultare i volumi di questo studioso (mi pare che tra le altre cose sia l'autore del fascicolo della Squadron SIgnal sugli U-Boot) e Le riferirò.
