Il-28 BEAGLE (ILYUSHIN) - Variants

IL-28U: training variant of the bomber. Its draft design was stated by Il'ushin in 14, October 1949 and after the 5 months, 18, March 1950, V.K. Kokkonaki rose the aircraft in the air. On the Il-28U the cabin of pilot-instructor was organized on the place the navigator's cabin. Pilots of air regiment under the command the hero of USSR the lieutenant colonel A.A.Antilov less then the moth on Il-28U mastered the aircrafts and 2, May 1950 battle Il-28 took part in air parade under the Red Square in Moscow for the 1st time. Il-28 was noticed when the Day of Aviation was celebrating in Tushino in 1951. The aircraft was assumed on the arming Soviet BBC and was built serially on the factory #30 in Moscow. The reference designation of NATO is Mascot.

Il-28R: Aircraft-prospector was intended to carry out a tactical and operative air reconnaissance in behalf of front, fleet and air armies. The 1st testing that aircraft did V.K. Kokkinaki in 19, April 1950. The factory tests were finished at the end of 1950, and after the successful ending of state testing the aircraft was accepted on arming by BBC. First its routine fabrication was on the factory #30 in Moscow but from 1953 the factory #39 (Irkutsk) began building them, which had produced the torpedo bombers Tu-14 before.

An equipment of day photographing consisted in three aerial cameras AFA-33 with focal distance 100, 75, 20 c and one AFA-RB for strip, planned and perspective surveys. The night photographing supplied with two aerial cameras NAFA-3s and a complete set of target indicators in which might enter FOTAB-100-60, FOTAB-50-35, SAB-100-55 and SAB-100-35. The equipment was in air-raid in automatic rocking installation and special photo cut off of the fuselage rear. Containers of aerial cameras were heated by warm air which was took away from heating system and cabin pressurization of the crew.

Because of the weight which increased to 22720 kg - maximal takeoff weight the size of the wheels of the main gear was increased. On the serial bombers instead of air system harvest and landing gear extension applied a hydraulic system, which allowed to reduce the time of the operation to the 8 sec. There was the system of wheels spinup the main gear in the air and before the landing. From two nose guns was left one to the port side. Crash boat LAS-3 might place when the flight was carried out over the sea and a middle part of a fuselage IL-28, and it control ejection carried out from the cabin the pilot and the stern gunner.

Then the development of Il-28R became the aircraft of radio intelligence, where the aerial cameras were changed to special radio equipment. Spatiality of these machines were radomes under the central part of fuselage.

The development of radar detection demanded the engaging in the battle formation the bombers of aircraft B. On the base of Il-28 such machines created by installation an apparatus in the bomb cut off to dispersion of dipole deflector blades or erection of active radio-interference. An additional work of the aircrafts led on the repair factories.

Il-28T: Torpedo bomber. In 1950-51 in OKB was designed, built and tested an experience torpedo bomber Il-28T. The main difference of it from the bomber was the increase the length of bomb cut off from 4270 mm to 6430 mm, where now can hang the serial torpedoes and mines: one torpedo the type of 45-36ANU 45-36AB TAC, PAT; one mine the type of Serpej, AMD-1000 etc. An aiming with low torpedo throwing carried out with the help of the sight PTN-45, the low part transcended of the fuselage and closed by spherical fairing. With the unimportant re-equipment of IL-28T could be used as a bomber with a bomb loading as a commercial machine. Increase the length of bomb cut off and placement in the fuselage of the crash boat LAS-3 defined the decrease of the capacity inside fuel tank, and to save the prior range flight Il-28 fitted out B on the wingtips. Il-28T passed the factory and state testing with success, but it did not build serially. The cause is too tightened finishing of torpedo 45-36MAH, which was accepted on the arming only in 1956, which signed 45-56HT. Besides, even new dimensions of the bomb cut off of IL-28 did not allow to increase the quality of torpedoes PAT-52 on it on the inside suspension bracket.

The decision was accepted to equip IL-28 of naval aviation outdoor braced holders B-4 alongside the fuselage. With them IL-28 (index T) could carry three torpedoes the type of PAT-52: one on the inside and two on the outward suspension. The usage steam-to-gas torpedoes the aircraft could carry two torpedoes the type of 45-56HT on the outward suspension. On the outward holders might have hanged the mines -500. The testing of the aircraft finished in 1955. It is supposed to re-equipped in that variant quantity of IL-28 of naval aviation, but it was not done - torpedo-carrying variants Il-28 from the 2nd part 50th, did not satisfied the demands of the fleet, and in 1956 the decision about the rearmament mine and torpedo aviations on TU-16 was accepted.

IL-28PL: When the service of IL-28 in naval aviation was finishing in the Balflot the aircrafts 769 mine and torpedo regiment (MTAP) were re-equipped to anti-submarine torpedo AT-1. The machines were signed as IL-28 PL. It difficult to say that that re-equipment was success because the flight duration of the aircraft was not absolutely enough to anti-submarine struggle. It was seemed that that aircrafts would operated by calling. It was regarded the offer about an analogous modernization of the aircrafts another two Baltic regiments, but it did not happen.

IL-28Sh:low-flying attack aircraft. Rather small loading of fighter-bomber in those days forced the military turned to the idea about the low-flying attack aircraft on the base of IL-28. The decision was accepted to place the weapon on the pylons under the wing even to the prejudice of aircraft performances. In the spring 1967 there were compounded TTT to the variant IL-28. According to them the modified aircraft must have had the same depth of hostilities as Su-7, but excelled it in quantity of means of defeat in 2-3 times.

Il-28, it is equipped the wing pylons to suspension the various weapons, it was intended to operations from the small heights by the gathering living force and technique of opponent, and by single low-sized aims the type of rocket installation, tanks etc. Under the wing of that aircraft 12 pylons were set (6 under the every cantilever), on which might be hanged: 12 blocks UB16-57 or 6 heavy NAR C-24, or hanging cannon gondolas or cassette weapon and aerial bombs.

The state testing of that variant (sometimes it was IL-28 SH) were began in autumn 1967. By the appraisal of the testers the aircraft could be recommended for the low-flying attacks from the small and nap-of-the-earth. Though the comparatively closed installation of pylons from the both sides of the air enginery , the volley fire 192 HAP C-5 or 6 C-24 on all the service-tested regimes of the flights did not take on the work of the force installation.

The advantage of the aircraft was the good overview from the cabins of the crewmen and a possibility of the battle work from the ground aerodromes. The speed of IL-SH up to the height of 200 m limited to 660 km/h, the fuel consumption during the flight increased on 30-50%. The tactical radius of action with load from 12 UB-16 composed 295 km. The preparation of the aircraft to the battle takeoff not more than 4 h. but because of the deficient amour guard of the crew and essential system, but the aircraft could not answer to all the demands which producible to the low-flying attack aircraft and the works in OKB by that aircraft were finished.

IL-28 FL: Flying laboratory. In 1952 during the finishing making RLS Sokol (developed in Research Institute-17, the design managers A.B. Slepushkin and G.M. Kunyavskij), which intended for perspective double seats interceptors Yak-120 and La-200, There was the necessity its fine-tuning on the real aircraft. While La-200 was modified became the LA-200B, Lavochkin offered to continue the development of Sokol in normal construction on the machine of the middle class. IL-28 was chosen. The fore part of the aircraft up to the cabin of navigator was cut to place the station and the operator. The construction of the force part had to intensify.

The special equipped 28th were tested to working-off of the equipped complex and outfit for the 1st flight the man in the space. Specifically the Il-28 were flight tested and outfit of the parachute eject mechanism and the system of rescue of space pilot of the spaceship Vostok.

Il-28 - Postal. In USSR the part of Il-28 was ready for needs GVF. There was the demonstration of arming and aiming equipment excepting PSBN. The aircrafts were marked as Il-20 and Il-28P. There was a training of flight personnel and attending personnel on it of different surface services for the testing jet airplanes, and at the end 1954 the crew of Aeroflot began to traffic regularly on the machines the post and cargos.

IL-28C: Continuing the work by modernizing Il-28, in OKB worked out a project of equipping Il-28 new engines BK-5 and a swept wing. But the work out showed that it had not the main flight advantages before the serial bomber IL-28, and all the works were finished. It was the sound decision.

Il-283A: Sounding of atmosphere. Modification IL-28 for carrying out the meteorological watch in atmosphere.

Il-28A - Carrier of nuclear weapon. When Il-28 had being made nobody knew that in the arsenal there was the nuclear bomb. But the increase of opposition of two political systems had to the machine had that function. This task was decided because of fast modernization Soviet nuclear weapon, as a result ammunition with rather low weight appeared. The work out of Il-28 concluded in equipping of bomb cut off and leading in a bar under the cabin of the stern gunner allowed to tow the special gilder-targets the type of - and 7B-2 on a rope the length of which was from 5-2500 m, where the pilots of cannon fighter and calculations of anti-aircraft artillery weapons were training. The endurance test of the aircraft-towing with the gilder-target was 2.5 h. Simultaneously under the wing of the machines could hang a dive target, which was equipped with a smoke tracer and a recovery parachutes.

IL-28M - unmanned target. In 1995 OKB Lavochkina began to design a zenithal rocket 400, which must provide of large industrial centers. For work out the aiming system of the rocket there was decided that on the base of IL-28 unmanned flight target. In 1955-56 on the aircraft was worked out the system which provided unmanned the execution of the flight, climb, the horizontal flight, some maneuvers in the air and boarding on the aerodrome. Afterwards those targets were used for the testing.

Il-28 on the track-type chassis. To the expansion of operational capabilities of bombersIl-28 there was designed, built and tested on-the-go on the earth the special track-type chassis. The ordinary serial aircraft which equipped by it showed the significant improvement of passability on the aerodromes with the soft, wet, covered with water, thawed snow or mud, ground. But because of difficulties of constructions and large weight that chassis could not find a usage, and an experience aircraft served as a tutorial in one of laboratory of .
