Antonov An-30
Antonov An-30 is a device designed for aerial photography and surveillance of the terrain. By codifying NATO organization is designated "Clank," and my own country is often called "Anastasia". This machine is designed on the basis of passenger An-24, only the last number of profound modifications. It can be used as a military intelligence officer.
History of An-30
This machine was designed in the walls of the Antonov Design Bureau in the summer of 1964 years. The basis of its creation were taken to the operating time of the AN-24. This version was primarily designed for the Air Force and Civil Air Fleet of the Soviet Union. That is why the machine is ready for both military and civilian use. It was equipped with the high-quality camera equipment at the time. Layout machine was ready in 65, and was presented to the customer.
The main difference between An-30 and the original aircraft was the forward part. An-30 is equipped with a glazed cockpit for the navigator, who was engaged in photography. Due to the installation of this cabin, the nose has become much wider. In addition, this upgrade allowed the installation of additional fuel tanks in the center wing and tightly closed the door into the luggage compartment. Also, the fairings under the fuselage of the car were installed. The cockpit began to be placed much higher, which allowed to increase the review for the pilots and the navigator. The management and maintenance of the machine in flight must be made by seven crew members. The device was intended to be equipped with photographic equipment, which would allow shooting on a scale up to 1: 150 000.
The first prototype was made in the design office of Beriev, which was located in Taganrog, at the beginning of 1967. For the first time the device detached from the runway in August 67 year. This prototype was 32 flight. A year later, An-30 passed tests at the Air Force Research Institute. By the summer of 68, all factory testing was completed, under which it was concluded that this unit has 6 thousand flight hours between repairs for 5 years. Tests by the state commission were completed in the summer of 70. In addition, state tests noted the advantage of the new model over the previous aircraft.
Serial manufacturing was started in 1971 year on the territory of the Kiev aircraft plant. Production continued until 1980 year, during this time 125 of such machines was produced. In addition to using An-30 in the territory of the USSR, it was exported to other countries of the world. For the first time the general public An-30 was presented at the air show in Le Bourget in 75. On the basis of a standard machine, a number of modifications were made, which were used to induce precipitation and for meteorological investigations. A machine for studying polar latitudes was also made. It was installed new navigation equipment such as "Toros" and additional fuel tanks to increase the range of flight.
Design features of the An-30 aircraft
The machine is designed for cantilever monoplane scheme, in which highly placed wings. Feathering was the vertical structure of the scheme, using the ridges under the body. A set of equipment for shooting and the location of crew members have been developed in two versions: for military and civilian use. The most significant changes were made to the nose compartment bulkhead 11.

Middle compartment machines previously designed for passengers in the An-24, and at the AN-30 were here are five covers for photographic equipment. Glass covers have a heating system that prevents them from freezing in flight. Manhole covers were opened with the help of electric drive. This compartment of the machine is equipped with a special room for display pictures. For the rest of the crew are provided folding bed and wardrobe storage.
Wings are located high and have a trapezoidal shape. The very design of the wing center section and is represented by four consoles. In the middle of the wing flaps set slot-like type, and on consoles - two sections of ailerons. They are equipped with servo tab and additional trimmers. Feathering tail is made in the cantilever scheme and has one fin made of metal.
The chassis of the AN-30 consists of three retractable racks that are installed pneumatic low pressure. Rear racks are cleaned in a special niche for the motors and the front desk - in a niche under the cockpit.
Powerplant scout AN-30 has two turboprop engines of the AI-24, which provide the aircraft at take-off power in 2,5 thousand horsepower. The motors mounted in the gondola of center. They drive the screws The four-feathering type, which are designated as AB-72. Start engine performs autonomous turbogenerator TG brand-16.
In this machine has two fuel systems, that are identical in their construction. Each engine has its own separate fuel tank in the wing. Furthermore, there is another tank in the center section, which can fill the one thousand liters of fuel. All tanks have a soft structure. When a failure of the fuel system can be connected in a single piece with a crane banding.
Electric power is provided by two generators installed on engines. When servicing the aircraft on the ground, there is a turbogenerator of the type TG-16. Two 30SAM batteries are installed on the An-12 board for emergency situations. The machine also has a system that prevents icing of the case with the help of warm air. The cockpit has an oxygen system, which is designed for 7 crew members. The hydraulic system provides chassis operation, flap rotation, windshield wipers. In addition, it can make an emergency stop of the engines. The entire hydraulic system consists of two parts that operate from hydraulic pumps and are driven by an electric motor.
At the moment, the car An-30 continue to actively exploit for surveying and intelligence operations in the CIS. Some devices An-30 reequipping a cargo or passenger plane on 20 seats.

I can say that for the time of An-30 really considered the best airplane. This machine during takeoff buzzing, vibrating, but 50-it's quite normal, then create the best machines can not. But even though these shortcomings, I believe that with the AN-30 can not be compared, no modern - Watermelon as "Annushka" best.
First flown on An-30 years ago. During the flight, we have not met air pockets, but when the plane was down, a little shake. But the noise of the engines, reminds me of just music. I flew for about an hour, but the most important thing after the flight I did not hurt your ears. I'd like to see these aircraft began to produce again, why invent new machines, if there are already proven. If someone would have to fly on the AN-30 should not be afraid, it's not a modern machine in the computer management.
I flew to the An-30 than once. It's a beautiful aircraft, it flies steadily, especially I like the way it takes off, it does not shake when climbing, and there is no excessive noise. In general, I can say one thing, the car is good, it is a pity that today do not produce such aircraft.
An-30 - it's a miracle - a technique well, at least I think so. The aircraft developed in Kiev, my hometown. I live close to the airport so early in the sky often seen this car. Today in our country there are very few of these aircraft. I myself had the opportunity to fly the An-30 Aunt visit. I was only 10 years and at that age, I did not pay attention to the quality of the aircraft. But I also had to fly the An-30 in a more mature age, and then, I appreciated this machine appreciated!
Those aircraft that was shot down by Slavic in June last year was the year of issue and 1967 47 years fly off! That's what "Made in USSR" Respect developers! This technique can only destroy an enemy shell.
