Suchoj Su-17 [kód NATO: Fitter-B]

Su-17

On the basis of the experimental aeroplane Su-7IG (project S-22I) began the design of the office P.About. Sukhoi in 1967 to develop a new fighter-bomber aircraft, according to the project S-32, later called the Su-17. According to the plan should be in 1968 produced two test aircraft, and since 1969 had run the serial production. During the development of the anticipated takeover of the construction of the wing of Su-7IG, the fuselage was taken from the Su-7BKL/BMK, elongated in zakabinovém space of about 200 mm for the new avionické equipment. Canopy pilot was new, similar to Su-7FOR the upper part is lifted up, the pistons controlled the air, the front label should be made from a single piece of organic glass. Between the canopy and the keel on the upper side of the fuselage was similar to the Su-7FOR, stretched along a low ridge and two smaller housings in the wiring. Short backup PVD-7 was on the right side of the bow of the hull. Taken was also modified the system of automatic adjustment of the input cone and protipumpážních door ESUV-1V with the adjustment of the door for air leaks during take-off. Bow nebržděný, hydraulics driven chassis was taken from the Su-7BKL, a was dual split doors. The main chassis was taken with minor changes in the kinematics of the Su-7BM/BMK. The engine was not yet elected AL-7F1-250 from the Su-7. No ejection seat was due to the new overlapping slightly modified from the aeroplane Su-7BKL/BMK/U the type of KS-4S-32. On the trunk were left locks for attaching the auxiliary take-off rocket motors, SPRD-110.
It was assumed the equipment of the aircraft new avionics. Was used the new autopilot SAU-22-1, úhloměrně dálkoměrný radio system of near navigation RSBN-5s, which the antenna system of the Pion was at the front on the main PVD and back in a small conical cover at the top of the vertical fin. Along with autopilem SAU-22 formed RSBN so-called pilotážně-navigation system Polet, which allow for automatic or command-return to airport and landing. In the cabin was for the system Polet place artificial horizon AGD povelově-piloting the device KPP and place the compass pointer navigačně piloting device IPA. In addition, he was on the pilot panel indicator of the distance of the VRS to radiomajáku or landing of the lighthouse. System Polet yet did not allow zaprogramování own and backup of the airports and other landmarks and the pilot had to manually choose channels of the radio and the landing of the lighthouse. Hydraulic, air, oxygen, air conditioning and other systems were taken or adapted from Su-7BKL/U. The fuel system was slightly modified compared to Su-7BKL should high school trupová tank and the integral tank in the moving parts of the wings of the smaller capacity. The aircraft can use up to 4 additional fuel tanks, capacity 600 liters. The system of protection of the entry of the engine from dirt SDUV was never used.

Armament was to be carried on four pylons, two under the fuselage and two under the wing. After the comments of the commission of the soviet air force were on the wing complemented by two pylons close to the fuselage, were but the carrying capacity of only 250 kg each, so the total bearing capacity of the equipment was 2500 kg. The commission also requested to change the front plate canopy for a classic with armoured glass and the use of protizemní missile Ch-23, but in the end wasn't in the arsenal of the aircraft included. Test her odpali were made until after the end of production of the aircraft in the autumn of 1972.In the roots of each half of the wing was one gun NR-30.
The first prototype of the S-32-1, also called the closing speed, was made in a factory in Komsomolsku-on-Amur at the end of 1968, there also from the beginning of 1969 there were ground tests. In April 1969 he was transferred by air to the airport in Žukovském, where test pilot Kukušev made 1. July 1969 first flight. The aircraft had the front plate of the cab from a single piece of organic glass and not from the beginning of the mountings number 5 and 6 on the wing at the fuselage. The second předsérouvý aircraft S-32-2 carried out the maiden flight 13. August 1969, and aircraft for static tests was built in April 1969. Aircraft With a-32-2 had armoured plate of the cab and mountings 5 and 6 on the wing. He was adopted as a model for the production of serial aircraft. For testing both pre-series aircraft added by the end of 1969 and the first serial aircraft number 8601. The first four production aircraft were manufactured by the end of 1969 and still have the front label of a single piece of organic glass. The front label was ofukován hot air from the compressor of the engine To other series were the classic panzer front labels heated electrically. The pre-series aircraft were tested and the serial aeroplanes introduced some improvements. The main wheels could be replaced for the skis, canopy got a periscope for watching the rear side. The planes were equipped with všesměrovým warning radar přijímace SPO-10, the armaments were supplemented by cannon containers SPPU-22, blocks UB-32A, disruptor SPS-141 and others. In the course of production was on the left side of the bow installed timer angle of attack and in the cabin its a pointer, the backup PVD-7 is shifted to the top left side of the bow of the aeroplane, the fixed part of the wing was fitted with another pair of aerodynamic ridges. Adjustments were retroactively made even the earlier produced aircraft.
The first formations of the soviet air force received new aircraft Su-17 in 1970. The total was in the years 1969 to 1972 produced 209 units. In 1972 it was made plus a small series of 16 aircraft, the export version with the unofficial designation of Su-17K (project-32K) for Egypt. They had some older version of avionics.
To this day preserve the aircraft With-32-1 in a factory in Komsomolsku-on-Amur, the first serial Su-17 8601 in Jejském aviation college, aircraft serial numbers 9024 is positioned in muzemu Monino near Moscow. In Egypt did the one Su-17K.

Lze se setkat s údaji o existenci verze Su-17R. Podle ruských pramenů a informací pilotů na ruských diskusních fórech taková varianta neexistovala. Všechny sériové letouny Su-17, jejichž sériová čísla končila nulou nebo pětkou měly, podobně jako letouny Su-7BM/BKL/BMK za šachtou příďového podvozku další šachtu, ve které byl jeden fotoaparát AFA-39 pro kolmé snímkování.

V podstate každé piate vyrobené lietadlo v sérii bolo uspôsobené pre fotografický prieskum.... Z toho je asi odvodené označenie Su-17R, aj keď v nomenklatúre nemalo lietadlo vlastné označenie.


V Sovietskom zväze asi nič mimoriadne - aj Jak-25 a Jak-25M boli v jednotkách oficiálne vedené iba ako Jak-25.
