Su-35 received a new optical-location system

34
Russian Su-35 fighters equipped with an OLS-35 optical-location system. It allows airplanes, without giving themselves away, to detect air targets from the heat of engines and to hit ground targets with high accuracy with bombs and missiles.




The equipment was developed and produced by the Scientific and Production Corporation “Systems of Precision Instrument Engineering”. It is located in a drop-shaped ledge, mounted in front of the lantern of the cockpit of a fighter pilot. It includes a sensitive video camera, a thermal imager, working day and night in any weather, a laser. The latter is intended not only to measure the distance to the target, but also to create an invisible spot that is “seen” by rockets and bombs with a laser homing head. Air and ground objects OLS-35 detects and takes to escort at a distance of several tens of kilometers. The video image and information received by the station are displayed on the windshield indicator in the cockpit. The key equipment of the station is a high-precision guidance system based on a virtual gyro-stabilized platform. Optical elements of the station are moved by actuators based on thin-film piezoceramics with accuracy measured by micrometers.

The system was successfully tested in combat during the Russian military campaign in Syria. An informed source shared with Izvestia the available information on this subject: - During the fighting in Syria, the Su-35 was not only accompanied by Russian front-line bombers and attack aircraft, but was also involved in delivering attacks on ground targets. The optical-location system has passed all the tests and received high reviews. Using OLS-35, fighters destroyed ground objects not only with high-precision aviation means of destruction, but also the usual freely falling bombs. A pilot using an OLS camera detected a target, determined its angular coordinates, and measured a range with a laser. This information was transmitted to the Su-35 sighting system. Next, the on-board vehicle calculated the necessary parameters for the exact destruction of the target.

According to Honored Test Pilot Roman Taskaev, the first optical-location stations were mounted on the MiG-29 and Su-27 fighters. - With the help of a thermal imaging channel, the station detects enemy aircraft from the heat of the engines, as well as from the structural elements of the aircraft, which are heated in flight. ¬Laser rangefinder determines the distance to the target. This information is displayed in the cockpit on the indicator on the windshield. The pilot, with the help of a special control system, turns the missile's head so that it captures the target. OLS allows, without including fighter radar, unnoticed by the enemy to detect it and strike.
At present, European Typhoon and Rafale fighters are equipped with Pirat and FSO sighting optical stations (Front Sector Optronics). They provide search, detection and measurement of the trajectory of the air targets. But ground target regimes are limited only to range measurement. Multifunctional OLS, working both for air and ground targets, is installed only on the American newest fifth-generation fighter F-35. F-22, as recently reported, in order to save was not equipped with infrared radars search and target tracking.

    Yes optics is cool! Yes, it is not possible to detect it! But unfortunately you can’t do without a radar

        Paul agrees! But the gun of the engineer Garin hasn’t yet gone to the mattresses! laughing why? the influence of the atmosphere ... also here if the pilot has doubts about the recognition of the target, he will turn on the radar, or he will use the help of the earth

      This is not bullshit.
      Our ordinary FAB-500 was laid on the ground in a piece of land meter per meter.
      The Americans and other "observers" were crazy about the prospect of fighting with such weapons, of which we have hundreds of times more than their "high-precision and very expensive" bombs

        Because not OLS, but SVP-24 "Hephaestus". Although a lot of things are being tested there, the SU-35 could also test the combination of a new OLS with an aiming computer for ground targets.

      That they can. They probably raised the resolution of the optics and introduced the IR channel. everything else was. Maybe they added the function of guiding missiles to the air surface on the laser, given the IR channel, around the clock ....

      You can sing and dance at the same time. I see no reason to be perplexed.
      For example, the French Pirat, FSO can measure only ground based range (I assume that the modernized ones can work completely on the ground). There is no built-in OLS on the F-35, only container EOTS, which is sharpened for work on the ground, in the air - no. Our OLS-35 station wagon.

        but this is generally .... [quote which "see" missiles and bombs with a laser homing head] [/ quote] .... as it is directed forward and up, stsuka will see a falling bomb, in which the laser radiation is directed down ??? wassat
        Well, in general .... to see, at the request of commentators, they changed the newsmakers .... to fierce copywriters lol

          https://topwar.ru/1509-istrebitel-su-35bm.html - здесь немного по ТТХ ОЛС-35, наземные цели ~30 км с точность 5м недостаточно? + именно в том, что подвесной контейнер не требуется.
          A laser seeker only has a receiving element, bombs do not illuminate the target but accept the reflected one. + OLS-35, that the laser of the OLS rangefinder is capable of illuminating ground targets for UAB, you no longer need to drag a hanging container with a laser-television sighting system.

    OLS-35, mounted on the fuselage, can hit targets only in the upper hemisphere, so it cannot work on ground targets. For such work, the OLS must be placed under the fuselage, like the F-35.

    Journalists are such journalists.

                Before firing (second case), the pilot, in the course of completing a strike mission, works for several minutes to tens of minutes in ground target detection mode. What, all this time he will pilot a plane with a negative angle of attack of the wing - this even the Su-35 does not know how.

                I’m saying that journalists are nerds in life, their texts on technical topics should be taken critically.

                    Modern attack aircraft operate on ground targets exclusively from horizontal flight outside the MANPADS and air defense range.

                    In Syria, the Su-35S worked on slippers from a height of 6000 meters. In the event of a general arms conflict, they will work either from extremely low altitudes or from a great distance. In both cases, optical detection and location of targets in the lower hemisphere with the location of the OLS at the bottom of the fuselage will be required.

                    In other words, for a multifunctional aircraft such as the Su-35S (unlike the fighter of the F-35 type), the mandatory presence of two OLS is required to combat both air and ground targets.

      So she’s standing there under the air intake, go to the CRET website a year ago, a photo of drying - one ball in the same place, and one from the bottom and they look different from the previous ones. with optics or something smaller. Balls we started until the 90s on all twigs-29 and drying-27 a masterpiece from Lomovtsy. Then, already through the air-flame of the engine, they worked at 50 km, and from the front projection - 12-18 km and the rocket's optics were brought in by sight. Amerikosy got acquainted with the ethyl principle of location only after the unification of the FRG + GDR.

    And then where does the prominence? The radar, and in the presence of an OLS, perfectly sees this aircraft. If he is a stranger, then they will bring him down even with the absolute silence of this aircraft.
    The article does not say a word about reduced visibility, then this is your speculation. In fact, we are talking about the detection of aircraft aiming systems by enemy systems. There is no radiation from the aiming system, which means no one is aiming at you. And the aircraft is perfectly visible to the enemy with the help of: either a ground-based radar or an airborne radar.
