naravno da pilot moze da izabere koju ce sledecu raketu ispaliti mimo racunara. to sam I napisao gore u prethodnom postu.


zile

tacno tako. miks ove dve rakete je izuzetno opasan po protivnika.

USSVoyager ::mislim da pilot moze da menja izbor raketa pri ispaljivanju na vise ciljeva

Naravno ,postoji dugme `vbor` ili tako nesto na rucici komande gasa za biranje `podvesok` na krilima ili trupu .

Moje je pitanje bilo dakle u slucaju gadjanja ( istovremenog naravno ) 2 vazd. cilja koja je procedura/taktika se koristi ...

Dakle lansiranje istovremeno 2 T i 2 R mozda ? Sto rece zixo najbolja opcija bi bila gadjanje jednog cilja sa recimo kombinacijom R i T .Opet kakav je postupak prilikom gadjanja 2 cilja odjednom ...

Ovo nismo odavno gledali ,obicno je to bilo sa onim poklopcem zelene boje a sad antena u punom sjaju ( nije bas neki ugao ali eto ponesto se i vidi poput `lampe` )

Malo vise detalja o

N001 / Myech / RPLK-27

NATO "Slot Back"

OKB: Tikhomirov NIIP

Chief designer: V K Grishin



N001 looks very similar to the MiG-29's N019 radar

Citat:The N001 radar for the Su-27 was designed by Viktor Grishin. Pushing the state of the art for the USSR, the original design, known as Myech, was supposed to draw heavily on technologies developed for the experimental Soyuz radar program led by NPO Istok. It was intended to have a great deal of commonality with the MiG-29's N019 Rubin radar.



N001 internals from factory website

Citat:Development was difficult. Originally intended to significantly outperform the AN/APG-63 of the F-15, with a 200km detection range, in reality this goal proved impossible for NIIP to achieve. It was intended to use an all new design antenna, featuring electronic scanning in elevation and mechanical scanning in azimuth. This would give excellent multitarget engagement capability, and use of the MiG-31's R-33 was envisaged. This design proved overly ambitious, and was simply unachievable for a mass production radar given the state of the Soviet electronics industry in the early eighties. In May 1982, it was decided that the NIIP designed digital computer and antenna were simply not up to scratch, nor likely to become so in the near future.

Phazotron's N019 had already reverted back to an improved version of the Sapfir-23ML's twist-cassegrain antenna to replace its problematic flat-plate antenna. It was decided therefore to use major components from the N019 radar, including a scaled-up copy of its twist-cassegrain antenna and the TS100 processor. By March 1983, the redesign was complete, though the resulting radar was nowhere near as good was intended. Instead of 200km, detection range barely reached 140km even against a large bomber.




Stills from NIIP video show the twist-cassegrain antenna



Citat:In 1985 NIIP were ordered to improve its performance. Attention and work had switched to the new N011 radar to equip the Su-27M, and problems with N001 persisted. According to NIIP, initial units had a MTBF of only 5 hours. Though the Su-27 entered service in 1986, its radar was not finally accepted into service until 1991. Eventually MTBF was brought up to 200 hours.

N001 has a 1.075m antenna diameter twist-cassegrain antenna. A pulse-doppler design operating in the 3-cm band utilising medium and high PRFs for optimum lookdown capability, the N001 has a search range of 80-100km against a 3 sq m RCS target in a headon engagement, 140km against a large bomber. It can track a 3 sq m target at 65km. In a pursuit engagement, search range for a 3 sq m target falls to just 40km. Azimuth limits are ±60° . It can also track ECM sources, and feed target data to the Su-27's IRST system.

The average power transmitted is 1kW (same as N019).

MTBF is 100 hours.

A radar datalink is used for updating inertially guided missiles such as the R-27.

The Su-27K used an updated SUV-33 control system, the N001 radar was largely unchanged but with sea optimised lookdown capability and support for the carrier-based GCI system.

Citat:A modernised N001 radar developed for retrofitting to in-service Su-27 (analogous to the Phazotron N019M Topaz) can track and engage 2 targets at once using the R-77 missile.

N001VE is fitted to Chinese Su-30MKK. Uses Baguet series BCVM-486-6 processor for additional capabilities. Basically the same as NIIP Stage 1 package below.

NIIP N001 modernisation package

Citat:Stage 1: Provision of ground mapping modes. Existing radar is modified with a bypass channel that allows incoming radar data to be switched to a new all-digital processing system. When a new mode is selected, radar data is sent to the new subsystems, but if an old mode is selected the data is processed as before by the existing radar hardware. Thus all old modes remain unchanged. New air to ground modes added are very similar to those of the Zhuk radar. Only 1 additional air-to-air mode, which gives RVV-AE compatibility.

Stage 2: NIIP propose a new lightweight, optically-fed Pero phased array antenna as a drop-in replacement for the existing cassegrain antenna. This will substantially improve air-to-air performance, and increase air-to-ground resolution. New modes will be added at the same time for target identification, velocity search, and to detect hovering helicopters. Suggested that range might reach 300km against a large target.

Upgrade to Stage 2 is expected to cost 35% of the cost of a new radar.

Ovo sam pa skoro zaboravio ,dakle u vezi mogucnosti lansiranja raketa V-V u doredjenim rezimima i okolnostima ...

imamo na cini mi se na 85 ili tako nesto stranici ...e sad jel to bas to nebitno ali u ovom dokumentu imamo zaista mnogo interesantih detalja

Da pojednostavimo ipak, SU-27..onaj sa pocetka 90-tih je mogao da lansira salvo R+IR samo u odredjenim uslovima, najpovoljnije kad je zahvat u zadnjoj polusferi, tojest ukoliko ima solidni O zahvat, i to na ne vishe od 7-8 km i naravno ukoliko ima istovremeni radarski zahvat na istoj toj daljini tojest vec ima sinhronizovane podatke sa oba lokatora ( Radar/ IRST ), tako da ako je zahvat u prednjoj hemisferi, salvo lasniranje R+IR je veoma otezano, jer na daljinama manjim od 5-6 km, na kojim moze da napravi IR zahvat u PPS-u radarski zahvat je veoma otezhan, pre svega zbog velikih ugaonih brzina cilja i slabe procesorske snage tadashnjeg radara Su-27 kod pomenutih situacija sa velikim ugaonim brzinama..
Ovo je ipak bolje od mogucnosti prvih Mig-29-ki recimo koji nisu ni mogli da naprave Radarski zahvat u zadnjoj hemisferi a pogotovo ako se cilj udaljava, to je pogotovo bilo veoma izrazeno kod prvih izvoznih 29-ki ( DDR, YU )
