Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.214.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 16:45, 10 January 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''ANT-2''' was the first all-metal [[aircraft]] designed by the [[Tupolev]] design bureau. A small passenger plane, it could carry two passengers in a cabin behind the pilot.

== Background ==
[[AN Tupolev|Andrei Tupolev]] saw the practicality of metal used in aircraft construction. Light metal alloys were more durable than wood and held up better in the severe Russian winters. In September 1922, a factory at Kolchuginsk, in the Vladimir region, approximately 121&nbsp;km (75&nbsp;mi) from Moscow, had fabricated a high-grade alloy, named Kolchugaluminum.   A special commission was established on 21 October 1922, within [[TsAGI|Tsentralniy Aerogidrodinamicheskiy Institut (TsAGI)]] to be headed by Tupolev, charged with developing tests of the metal's strength and establishing all-metal aircraft production. The design bureau had fifteen engineers, technicians, and draftsmen.  The first components made at the bureau were used to train craftsmen in aircraft fabrication using the new materials.

The creation of duraluminum was regarded by Tupolev as the Soviet Union's aviation industry's birth. Building the required alloy-working skills was a challenge to Tupolev, TsAGI, and the factory in Kolchuginsk. Trialling the new materials on aerosleighs, boats, and gliders, they developed techniques not used at the time by the leader in the industry, Junkers, but which proved to be at least as effective.

==Design and development==
The ANT-2's construction was done by TsAGI's AGOS division on floors one and three on 16 Radio Street in Moscow. The design was a cantilever high-wing monoplane with a triangular cross-section, which proved useful because of the increased strength and rigidity, which reduced the need for fuselage struts to keep the same shape, and added the aerodynamic benefit of avoiding vortex drag under the aft fuselage. The fuselage was divided into three sections: the first gave easy access to the engine for inspection, the second was an enclosed area for the two passengers, who faced each other- with an entrance through a door on the side of the fuselage, and the third, left vacant, was the tail elements. The passenger area was behind and below the cockpit, where the pilot was in an open canopy. Similar to contemporary [[Junkers]] designs, the aircraft skin was made of corrugated iron sheeting. The engine was a British [[Bristol Lucifer]] piston engine which could produce 100 HP.

Completion of the first aircraft was in May 1924, with two sacks filled with sand to represent the passengers' weight. The first flight was on 26 May, conducted by Nikolai Petrov. The ANT-2 proved difficult to manage and unstable in flight, but its handling qualities were improved after enlargement of the tail. However, due to material shortages in the USSR, and difficulty in obtaining engines, the project never reached the stage of mass production.

==Survivors==
A surviving example of the ANT-2 is preserved at the [[Central Air Force Museum]] at [[Monino]], outside Moscow, Russia.<ref>[http://www.moninoaviation.com/1a.html] ((Webarchive|url=https://web.archive.org/web/20110927103624/http://www.moninoaviation.com/1a.html |date=2011-09-27 )) Monino home page</ref>
