PS-9 (ANT-9) - trimotored short-haul passenger aircraft. Made in the USSR at the end of 20-ies of XX century.

History PS-9 (ANT-9)

The development devyatimestnogo main passenger aircraft ANT-9 began to engage in far 1927 year. Then the joint efforts of society "Dobrolet" and the Office of the Air Force identified the main requirements for this class of aircraft.

Design PS-9 (ANT-9)

ANT-9 arranged scheme cantilever vysokoplana who had fixed landing gear and all-metal fuselage structure with a corrugated skin, similar to a military aircraft of the ant that time. The prototype was completed ready detachable parts of the wing and tail surfaces of the fighter F-6.

As part of the power plant were three French air-cooled engine, the power of each component 230 hp One motor is installed in the nose of the fuselage, the other two were placed in the center section of the wing. This arrangement secured the process of the flight, but the complicated maintenance of the machine. It took a long time to spend on a readiness check of the aircraft before departure.

The layout of the fuselage ANT-9 resembled the aircraft to-5: for a motor housed in the fuselage of a closed two-seat cockpit (having dual control), passenger cabin, a wardrobe, a toilet and luggage compartment. The passenger cabin is equipped with nine seats, made of woven reeds, which were later replaced kolchugalyuminievymi chairs.

The longitudinal balance of the liner provides a control in flight stabilizer, which could change the angle of its establishment on -0,5њ to -6њ.

In the spring of the year 1929 state tests began passenger aircraft, which lasted several months, and in June was successfully completed. During test flights showed ANT-9 209 speed km / h, with the payload kg 1700 and 5400 kg take-off weight. Climb 1000 m was achieved 6,5 min., Practical ceiling - 3810 m. Takeoff ANT-9 290 was on the rise m, and after planting - 150 m.

12.06.1929. On the plane ANT-29, a test flight was made for a distance of 4000 km. The plane made a huge detour on the way from Moscow to Kiev through the cities of Sevastopol and Odessa. Supervised this flight test pilot MM. Gromov. But this check for long distances has not ended. A month later, under the control of pilot M. Gromov and flight engineer V. Rusakov, an incredibly long flight by the standards of that time - to 9037 km was made. The plane made landing in the largest European capitals: Berlin, Paris, London, Rome and Warsaw. An experienced aircraft, which carried out this grand flight in the distance, was given the name "Wings of the Soviets", the duration of the flight was 53 flying hours.

The ability to perform such seemingly impossibly high for civil aviation at the time the job was accompanied by a decision in the same year, the launch of 1929-9 ANT into production. Three years later, the industry has prepared for the needs of civil air 70 new aircraft. In the series-built apparatus to replace components of the power plant. The first prototype had three air-cooled engine with a total capacity 690 hp Then they were replaced by domestic motors M-26 (3 300 x hp).

After the collapse of serial production of the latest aircraft engine converted, it began to put two motors M-17 (500 / 680 hp). These improvements made it possible to improve the performance characteristics of ANT-9. In particular, the maximum flight speed, compared with the first cars increased by 40 km / h, range increased to 700 km and service ceiling has reached a point 5100 m. Therefore, decided everything ANT-9 overstaffed engines M-17. Aircraft with a new power plant put into operation, received the name SS-9.

A number of aircraft SS-9 long time was at the disposal of civilian airlines of the country. Some of the aircraft showed a record for the amount of time naletnyh hours, which reached a value 5200.

In addition to military orders Department of TsAGI, he studied under A. Tupolev experimental creation of all-metal aircraft, also worked on the design of the passenger car. At the end of the Civil War, the need for it has increased many times - it was necessary as soon as possible to cover the whole country with a network of peaceful transportation.
The aircraft was intended for the flight of nine people in fairly comfortable conditions - a cabin for two crew members, a specially equipped lounge, a luggage compartment and even a toilet. In the design we used well proven elements of the wing and feathers on P-6. ANT-9 planned to install three engines - in the bow and on both sides on the center wing. In addition to providing sufficient power, this scheme increased the level of safety, which was important for a passenger car. The layout was accepted, the comments were taken into account, the plane was recognized as successful and finished. But in the course of exploitation, difficulties with engines started. As a result of alterations of the PS-9 (so it became known as ANT-9) they were equipped with two engines.
One copy was finalized for propaganda purposes. At the time, it was fashionable to use the aircraft for that purpose. Nose SS-9 supplemented stylized toothy maw and gave the name of the famous satirical magazine - "Crocodile".

Leonid summer 66. They are also made at the Moscow plant. The rest of the numbers are likely low. 75 else can endure due to refurbishment and resupply, but the version of the more than one hundred precisely eliminated. Used old engines stopped producing. PS began to hurry to convert to the new M-17. But the reason was not in the plane. At that time, the team Tupolev was working on a new model. A "nine simple alloys for civilian use, where they themselves fared.

Hello dear old Soviet aircraft. I have a question about the number of built SS-9. Nobody hour not tell how many there were? I just have information about 66 units. But I'm not sure. Quite common data, and even more than 75 100. And what fine, I do not even know. And one more question. Apart from the Moscow Aviation Plant №22 what other factories engaged in production of these aircraft? Who knows write.
