The aircraft Tupolev ANT-25. A photo. History. Characteristics.


ANT-25 - metal cantilever single-engine nizkoplan having a large elongation of the wing. several record flights were performed on this plane. It was created in the TsAGI Brigade PO Dry under the guidance of A. Tupolev in 1932 year.

From Tupolev ANT-25 I came not with the reliability and performance characteristics, with whom he later made his record-breaking flights. In 1934 was in the Air Force Institute to establish a range of records prepared instance ANT 2-25 (IF Petrov, and AI Filin). Through the installation of a special carburetor, polished surface of the protruding components, slinky cloth wings, aircraft engine installation with gear flying range was increased to up to 7500 12 500 km.


The main feature of the aerodynamic circuit ANT-25 - use it with large wings relative narrowing and elongation, equal respectively 5,3 and 13,1. With this elongation was reduced inductive reactance of the wing, which is associated with the magnitude of the lifting force. To increase stiffness and reduce weight wing resulted in structurally-power circuit of an airplane wing. It performs trehlonzheronnym.

Struts and strut poluubirayuschegosya main landing gear wheels with double brake and oil-air cushioning in each rack fastened to the middle and front of each half-wing spars. The wheels of the main landing gear in the retracted position half belonged to undercarriage and wing fairings were closed. Also, half of its diameter was closed ventral fairing tail wheel. Parts of the surface of the wing and the leading edge of the first ANT-25 was scheduled corrugated.

The fuselage of the aircraft consisted of two main parts: an anterior one, which is a truss structure made in one piece with a wing center wing, and a rear (tail) - semi-monocoque with a working skirting. Motor-motor with the engine was attached to the front of the fuselage, separated by a firewall from the 3-local cockpit, which was arranged in the tail and front parts of the fuselage. In the cockpit there were (sequentially): the workplace of the main pilot under the folding transparent lantern, the sleeping places of other crew members, the navigator's workplace with radio navigation and radio communication equipment, the astroluk and the co-pilot's workplace with aircraft control posts with a glazed upper hatch and side fuselage Windows.

On board the aircraft it was supposed to install modern navigational and flight equipment: a gyromagnetic compass, an air horizon, a radio and gyro compass, an aviation sextant, and later, in connection with the organization of flights in high latitudes, a course pointer. Thanks to such equipment, the aircraft could fly at any time of the day, despite the clouds. Behind the cockpit, the rear (tail) part of the fuselage passes into the keel, on which there is a stabilizer with a variable angle of the installation in flight. The fuselage is smooth, and the rudder and stabilizer are corrugated.


In conclusion, I would like to bring another fact from the biography of the ANT-25. VA Chizhevsky, creating the first aircraft, revealed that their mass-geometric characteristics similar to the aircraft taxiways. Thus, it was possible to borrow feathers, wings and other structural elements that have reduced the time of creation stratoplanov BOC and BOC-7-1.

Very interesting is the fact that the plane is called not only to ANT-25, but as more and taxiways. A "RD" means - distance record. I did not understand what made the record that plane, but then read his entire story is completely understood. At this very ANT-25 several record flight it was committed.
Most of all I was interested in the fact that the aircraft was only experimental. It was created not for any particular purpose. Perhaps in the future if he passed all tests, and he was found able-bodied, and so on, it would have got under production, and so no.
Also, very much intrigued by the fact that the developers of the aircraft would make a nonstop flight on the route Moscow - North Pole - San Francisco. I think he would have succeeded if it had not happened to problems with the engine (oil leakage).
What surprised me is that the ANT-25 10148 already flown away. In a straight line and smooth curve 11000. It was a world record at the time. This distance was a very, very large. H sorry of course that is already in 1937, the aircraft transported in disassembled form on the ship "Cooperation".
In my opinion the aircraft is very good, because virtually no drawbacks. Such a plane like this one made a big change in aircraft.

Cool for a forties. Fly over 12000km not everyone could. No wonder it is called RD - distance record. Gromov with Owl 75 hours while the air lasted. I'm in the club on modeling. And I would like to ask, can anyone knows. And how much it weighed? Just the information and did not find. Those who respond thanks in advance.

Truly worthy of the aircraft. Just the same period legend 30-x - 40-ies. It was he who in 1937m from the capital at a distance 9000km flew to the United States, and after about a month of its modified model (like Gromov led her) flew 11000km. ANT-25 many records ... a very good aircraft were delivered.
