Ilyushin Il-38

 

IL-38, which NATO reporting name was May, - anti-Soviet aircraft Ilyushin Design Bureau. The basis for its creation served as a passenger Il-18V. Purpose of the aircraft was to individually or together with anti-submarine ships searching for submarines and their destruction, for maritime surveillance, search and rescue operations.

History of IL-38

Start designing anti-aircraft IL-38 dates back to 18.06.1960, when the Soviet Union issued a decree instructing the development unit OKB-240 GKAT. Even before that date, we decided on the base model, which will be carried out design. She became well-established IL-18V. Although alternatives as such at that time did not exist, and the construction of the aircraft from the ground required a huge capital resources and a lot of time.

IL-38

The performance requirements for the new machine have been approved by the anti-chief of the Air Force 4.05.1961.

Completion of construction of the first copies of the IL-38 without special equipment outlined in the second and fourth quarters of 1962

The OKB-240 1961 he defended in sketched-technical project antisubmarine aircraft IL-38, having a part of the equipment of search and sighting system "Berkut".

Defending has been said that most of the region the use of IL-38 become the Norwegian Sea to detect ballistic missile submarines. Unfortunately, the plane did not have enough equipment for application in arctic conditions of the northern seas.

IL-38 video

The aircraft was designed at a time when practically all military aircraft (reconnaissance aircraft, bombers, interceptors, etc.) were equipped with defensive weapons. This made it possible to create the illusion of invulnerability and increased the chances of successful completion of the operation. But on the Il-38 places for defensive weapons were not allocated. Ilyushin decided that the installation of even the most ordinary aft turret cannon installation weighing 1,5-1,8 t would require an increase in the number of crew, the presence of a radar sight, which, together with the weight of the weapon itself, would substantially increase the take-off mass of the aircraft, which would undoubtedly affect the deterioration of the aircraft.

IL-38 was first raised to heaven as a test pilot VK Kokkinaki 27.09.1961.

IL-38

Compared to the baseline IL-18V airplane has undergone many improvements and changes.

  • The fuselage isolated two heated compartment of buoys, torpedoes and bombs, the total weight of up to 5370 kg.

  • Wing moved to 3 meters ahead and changed the design content.

  • The fuselage put additional fuel tank.

  • Disconnect the engine control unit and aircraft.

  • We made significant improvements in the design of many systems.

IL-38 cabin

In May and June 1962 held in Moscow estimate the layout of the IL-38, equipped with radar, "Golden Eagle". The main conclusion was that the anti-aircraft fully complies with specified performance characteristics and equipment of the "Berkut" is located conveniently. The main problem was a complex of anti-submarine aircraft equipment. Institute, is developing a system of "Berkut" I had not faced similar tasks, but only on the creation of specialized radio equipment.

State tests of IL-38 with onboard radar "Berkut" were conducted with 6 15 June to December 1965 near the city of Feodosia, committed 87 flights lasting more than 287 hours. The plane survived the test program, and 17.01.1969 Il -38 with PPP "Berkut" adopted by the Navy of the USSR.

IL-38 cabin

Serial production of anti-IL-38 1967 began in the year and continued until 1972 In this period was built 65 devices that 4 times less than the stated needs of the time.

The design of the IL-38

The fuselage has a length of 40,07 m. The length of the tail boom with a nonmagnetic metal and part - 5,6 m. The diameter of the fuselage - 3,5 m. The front of the cabin crew takes. Its area is 28 m2. The crew consists of seven members: the captain, his assistant, the navigator-operator, navigator, navigator, navigator-operator SPIIU, radio operator and flight engineer.

Issue and retracting the landing gear, the rotation of the front wheel, the opening and closing gruzolyukov, braking wheels - all this is done with the help of hydro-nitrogen system. The aircraft is also nitrogen system, due to which the emergency braking, emergency feathering propellers, etc.

IL-38

IL-38 location has air conditioning system, the purpose of which is to boost, ventilation and heating pressurized cabin. The peculiarity of this system is to bleed air from the engine compressor.

The structure of the power plant consists of four turboprop aircraft engine AI-20M and propellers AV-64. Until such time as the IL-38 put into service, it supplied more automatic feathering, which increases the safety of the flight. Start the engines can be made through external airfield power sources or using equipment turbogenerator TG-16, which is placed in the rear fuselage. The main disadvantage of the power plant, used in the IL-38, was a large amount of time required to warm up the engines (up to 10 min.).

PPP "Berkut", which is housed in part of the equipment of the aircraft has been developed on the basis of many scientific achievements 50-x and 60-ies. The structure of the automated system includes ergasticheskoy radioakusticheskie buoys (resettable component) and on-board equipment.

IL-38

Onboard equipment includes radar, airborne priemoindikatornym SPIU device, a digital computer system of a digital computer, the communication unit with a digital computer, the panel geographical coordinates Freight, remote data entry LDPE, etc. The executive and indicator device is a flight-path-navigation system 4B-2K, ARC-B, AP-6E, control panels throwing weapons and searching, light boards.

At one time I was a senior technician in the IL-38. The machine is very reliable. During the operation there was no accidents through the fault of technology. Disadvantage: obsolete design of the fuel and engine oil system - many dyuritovyh compounds, hence much time is spent on the maintenance of these pipelines

As for me, as a modernized Il-38N much better than its predecessor in combat capabilities. But whatever there may be, the car is quite interesting.

I live in the village of Nikolayevka in Primorye and see these beauties regularly. Guard sea borders
