O ovoj tematici a vezano za sisteme komunikacije ( medju njima i poznati data-link sistem APD-518) nije bilo govora dosada pa evo nekih info u vezi sa tim

za pocetak jedna skica



Skica pokazuje manje-vise vec poznate i vise puta komentarisane stvari i mogucnosti jednog od prvih u svetu operativnih fighter to fighter data link sistema ( postoje podaci da je mozda prvi oper.-ni sistem bio svedski `STRI-60` na lovcima JA-37 Viggen od 1982g,naravno iz zapadnih izvora a ako uzmemo u obzir ruske izvore kao i cinjenicu da je MiG-31 postao operativan vec 1981g onda predhodni podaci bas i nisu precizni ) ,inace kompletan sistem komunikacije (ukljucujuci i data- link APD-518) kao i radar RP-31( N-007 / SBI-16)` Zaslon` u paketu sa prvim digitalnim racunarom `Argon -15` u vazduh je prvi` poneo` sa sobom drugi prototip` 83-2` 22 aprila 1976g.
Sama skica pokazuje kao sto znamo taktiku poluatonomnog dejstva koji se sastoji u patroliranju cetiri aviona u frontu sirine 800 do 900 km gde vodja grupe prima podatke od GCI ili recimo A-50 a onda sistemom APD-518 salje poodatke o taktickoj vazdusnoj situaciji ostalima u grupi sto ce reci radarska slika se od vodje grupe automatski prenosi na radarske ekrane ostalih clanova date grupe .


Communication:
R-862 UHF, R-864 HF, P-591 voice warning system, SPU-9 intercom; SRO-2P IFF transmitter and SRZ-2P receiver; SO-69 transponder. Flight: A312 Radikal-NP or A-331 Shoran, A-723 Kvitok-2 Loran. Marshrut long-range and Tropik medium-range nav systems. ARK-19 radio compass, RV-15 radar altimeter, RPM-76 marker beacon receiver. Mission: In four-aircraft group interception mission, only lead MiG-31 is linked to AK-RLDN automatic guidance network on ground; other three MiG-31s have APD-518 digital data link to lead aircraft, permitting line-abreast radar sweep of zone 430 to 485 n miles (800 to 900 km; 495 to 560 miles) wide by 140º sector scanning angles. Semi-retractable Type 8TP IR search/track sensor under cockpit; tactical situation display. BAN-75 command link; APD-518 digital air-to-air datalink; Raduga-Bort-MB5U15K air-to-ground tactical datalink; SPO-155L RHAWS; Argon-15 digital computer.

Evo jos nekih zanimljivosti vezanih za ovaj sistem

Thw MiG-31's datalink (APD-518 Intra-flight Datalink) was very very well in service when the aircraft entered servie in early 80s. Indeed, Su-27S/P (only VVS/V-PVO nomenclature have nothing to do with special setups) had also a very very similar IFDL to that of the MiG-31 since the IOC in 1985, the TKS-2-27/K-DlA, that allows up to 16 aircraft to share information (radar contacts, targetting priorities, aircrafat position, etc) over a 10sec refresh date (6.5sec for 4 group a/c, 2 sec for 2 group a/c). The datalink simbology is pretty similar in both aircfat and I would made an educated guess that both datalink are compatible.

What made the MiG-31's IFDL different from that of the Su-27S/P is that it allows full a/c control over the "slaves", this means, that the commander of the group could make control directives (just like the Vozdukh-1/Lurch series of C2BM sets) and direct their aircraft towards targets and so. This is not allowable in the TKS-2-27.

Bot aircraft had Lazur type datalinks too (running in 300-400MHz frequency with from 30 to 300bits/s of speed), while the TKS-2-27 at least could run in IFDL modes at up to 4.6kb/s of speed. I don't know if TKS-2-27 allows one Flanker to share fire control of an R-27R/ER from another Flanker, but I'm pretty sure this is a possible cpability for the APD-518 (and maybe the little improved set installed in Su-27PU specialized Long-Range Air Superiority/Air Defense Fighter for V-PVO).

Both sets could receive intercept directives AND target info from Rubezh/Senez/Lurch/Vozdukh-1 sets and from A-50 SDRLO.

The MiG-31B uses a little improved version of the APD-518 (don't know designation sorry) that allows not only to receive or interchange contacts between the group BUT also to send information/contacts to command posts (to Rubezh C2BM per example) so they can send the info through the chain to other Air Defense assets (like the Polyana-4DM or Baikal sets for control of Air Defense Brigades and Regiments), forming a better SA for all around. Also the range of comms was 4 times longer (make sense) and more jam-proof.

I don't know exactly how did the Tu-128-M4 (or wathever is called I'm not that good with those pocket-interceptors) works, but could guarante you, isn't the same thing as APD-518/TKS-2-27. From operation frequency, to bandwith to just interface...don't see it

n fact it is so powerful that the flight leader of a formation can act as a small AWACS (basically a giant plane with a giant radar) if linked to a ground radar and another air crew. It can also passively detect aircraft with a retractable infrared search-and-track sensor common to Russian aircraft, but rare on their western counterparts. The Mig-31 can even track and kill targets such as cruise missiles from ground level up to its maximum altitude.

"A unique weapons control system took care of the mission, enabling the aircraft to operate as an airborne command post (ABNCP). A flight of four MiG- 31s, the lead aircraft acting as ABNCP, could trade target information over a strip of terrain 800km (500 miles) wide. The interceptors could split multiple targets between themselves, or pass some of them on to the leader of another patrol if there was more that they could chew. All radio communication was automatically on channels protected from electronic eavesdroppers. Three MiG-31s patrolling an area could provide 360 degree coverage. Besides, a MiG31 could direct up to three of its fellow MIG-23P 'Flogger', MiG25PD, MiG-29 'Fulcrum" or SU-27 'Flanker' interceptors, obviating the need for them to use their own radars and thus reveal their position."

Topce nastavak storije




Caliber: 23x115mm

lenght: 1412mm

Height: 205mm

Width: 181 mm

Rate of fire: 8000 to 8500 rounds per minute.

Weight: 71 kg.

Feeding: Disintegrable belt 250 rounds ( Su-24), drum 400 rounds ( MiG-31)

In spite of the russian tradition to keep the aircraft guns as light and uncomplicated as possible, the NII-6 armament office began the design of a multibarreled, rotary, gatling like fighter gun ( TKB-613) in late 1965.

The GSh-6-23 ( obviously the 6 figure indicating the number of barrels) was derivated of the naval AO-18 and developed at the same time of the troubled 30mm variant. The influence of the USAF M61 vulcan was quite evident in this entire weapons program since the Soviets had no rotary gun designs before the introduction of the american gun in service in late 1950s.

Means for rotating the barrel are not, however, an electro-hydraulic motor as in the US gun but gasses bleed from the gunl. The gas keep pushing a radial layouts pistons to ensure the gun rotaty movement. To break the inertia its first shot used also a pirotecnic aid in the shape of an small blank cartrigde. 10 cartrigdes are carried insided the mechanism to provide the chance of the same number of burst.

Originally the goal with this weapon was to achieve 12000 rounds per minute ( 200 per second ), quite unreallistic due the enourmous heat, stress and recol that a rate of fire so tremendous would cause. Aniway the russian keep pushing and in 1970 managed to achieve 10500 rounds per minute in short burst in ground test.

The production variant had the rate reduced to 9000 to 8000 rpm ( like a rate of 150 shots per second could be call reduced). 3 variants of this gatling gun were produced, the 9A620, the 9A768 and the 9E638, basically the same gun but with small differences in feeder location and rate of fire.

The GSh-6-23M ( 9A768 ) was adopted in 1974 for the Sukhoi Su-24 attack aircraft, Mikoyan MiG-27 and the MiG-31.

i naravno nesto i o radaru glavnom adutu 31-ce

The Russian (former USSR) Zaslon is an all weather multimode airborne radar developed between 1975 and 1980 by the Tikhomirov Scientific Research Institute of Instrument Design as part of the weapons control system of the MiG-31 supersonic interceptor. The NATO codename for the radar is Flash Dance with the designations "SBI-16", "RP-31", "N007" and "S-800" also being associated with the radar.
The N007 Zaslon was the first phased-array radar to enter service on a fighter aircraft. In 1968, Phazotron had been tasked with developing the radar for the future MiG-31. Engineers prepared two prototype units, dubbed Groza and Vikhr, both based on Sapfir-series technology. The final version was called Smerch-100, but the radar failed to meet requirements. As a result, in 1971 Phazotron was ordered to pass all the documentation to its consortium partner NIIP. The result was the Zaslon radar. The task was very difficult, since one of the main requirements was engaging cruise missiles, and the experienced Phazotron had failed to solve the problem of detecting small objects against ground clutter and tracking multiple targets simultaneously. Finally all the problems were solved, with lots of assistance from NPO Istok, who helped design the phased array, and Leninetz who were to build it, and the system finally reached service in December 1981. Zaslon is double the weight of the AWG-9, the largest US fighter radar. The NIIP team believed that the advantages a phased-array radar gave in terms of near-instantaneous scanning and multitarget engagement capability (a typical mechanically-scanned antenna can take 12-14 seconds to complete a scan) were worth the weight and cost penalties. First tests of the radar were conducted in 1973, and it was first flown on a test aircraft in 1976. On February 15, 1978, a mission in which ten targets were detected and tracked was performed for the first time. In 1981, MiG-31 aircraft carrying the Zaslon radar entered service with the Air Defense aviation, and became fully operational in 1983.

The 1.1m diameter, 30cm deep, phased array antenna weighs 300kg, the whole radar weighing in at 1000kg. Zaslon uses an Argon-15A computer (first airborne digital computer designed in USSR). Zaslon operates in 9-9.5 GHz band. It detects and engages targets down to 25m, including cruise missiles. Maximum possible search range is 300km for a large airborne target.

Range, headon, versus bomber: 180-200km search, 120-150km track

Range, tailchase, versus bomber: 90km search, 70km track

Range, headon, versus fighter : 120-130km search, 90km track

Zaslon can detect targets as small as 0.3 sq. m radar cross-section (RCS) to a maximum range of 65 km

Radar scan limits are ±70 azimuth, +70/-60 elevation.

Target track TWS mode, track 10 and engage 4.

Average power transmitted is 2.5kW.

MTBF is 55 hours.

Variants:

Zaslon-A security of the Zaslon system was compromised by the US spy A. Tolkachev. This lead to development of an updated version, fitted to MiG-31B from 1990, retrofitted to some earlier models during rebuilding to MiG-31BS standard. It had a new data processor, giving extended capabilities, longer range and better ECM resistance.

Zaslon-M 1.4m diameter antenna, 50% to 100% better performance than Zaslon. In April 1994 used with an R-37 to hit a target at 300km distance. Search range 400km versus a 19/20 sq m RCS target. Tracks 24 targets at once, engages 6. Supposedly able to engage launched Pershing-2 missiles in flight with long-range R-37 active radar-guided missiles. Project ended as no new MiG-31s will be built.

Zaslon-AM all MiG-31s remaining in service are supposed to have their radars upgraded to Zaslon-AM status by Leninets, according to a design put forward by NIIP that keeps the existing antenna while replacing the old Argon-15A processors with Baget series processors.
