Tupolev TB-1

The Tupolev TB-1 (development name ANT-4) was a Soviet bomber aircraft, an angular monoplane that served as the backbone of the Soviet bomber force for many years, and was the first large all-metal aircraft built in the Soviet Union.

Design and development

In 1924, the Soviet Air Force instructed TsAGI, (Tsentralniy Aerogidrodinamicheskiy Institut or Central Aerohydrodynamic Institute) to design a heavy-bomber. TsAGI gave the task to the division led by Andrei Tupolev. Tupolev's team designed a twin engined all-metal monoplane with a corrugated Duralumin skin, powered by two Napier Lion engines, the ANT-4.

The first prototype was built during 1925 on the second floor of Tupolev's factory in Moscow, it being necessary to knock down a wall to allow the aircraft to taken out of the building in pieces. After re-assembly at Moscow's Khodynka Aerodrome, it was flown on 26 November 1925.

Testing was successful, and it was decided to put the ANT-4 into production as the TB-1. Production was delayed, however, by shortages of aluminium, and by the need to find a replacement for the expensive imported Lion engines, the BMW VI (and later by the Soviet licence-built version, the Mikulin M-17). Production eventually started at the ex-Junkers factory at Fili, Moscow in 1929, 216 following the two prototypes, production continuing until 1932.

Operational history

The first production aircraft was completed as an unarmed civil aircraft, named Strana Sovyetov (Land of the Soviets) for a propaganda flight from Moscow to New York, taking an eastward course via Siberia, reaching its destination on 3 November, flying 21,242 km (13,194 mi) in 137 flying hours. The TB-1 became the Soviet Air Forces' first standard heavy bomber, also being fitted with floats for use as a torpedo bomber (TB-1P), and for aerial survey operations.

It was also widely used for experimental purposes, being the first mothership used in the Zveno Parasite aircraft project, carrying two I-4 fighters over the aircraft's wings.

The TB-1 was replaced as a heavy bomber by the similar, but much larger, four-engined Tupolev TB-3, with many aircraft being converted to civil freighters (designated G-1) for use by Aeroflot and Aviaarktika, Aeroflot's polar division. One Aviaarktika ANT-4, flown by Anatoly Liapidevsky played a key role in the rescue of the crew of the steamship Chelyuskin, which sank on 12 February 1934 after being trapped in ice near the Bering Strait, Liapidevsky being awarded the title of Hero of the Soviet Union. G-1s continued in use with Aviaarktika until 1948.

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
