    Mikoyan-Gurevich KM-1

    Katapultážní seat KM-1 was formed in the soviet design office OKB Mikoyan-Gurevich in the early 60's.years as a modern replacement of the existing seats KK-1 and SK-1 for aircraft Mikoyan-Gurevich MiG-21. The basic idea was to construct a sufficiently simple and effective seat with the best parameters including the ability to catapult the pilot on the ground (i.e. the characteristics of the 0-0). The seat had to be also, what is the most compact because the size of the cockpit of the Mig-21 was no longer possible to change. So there was a relatively simple seat with a pyropatronovým the drive and the dorsal parachute and the possibility of ejection from zero altitude (up to a speed of 180 km/h). First aircraft not where was the new seat used was a jet fighter aircraft Mikoyan Gurevich MiG-21US and subsequently got even on the other type of OKB Mikoyan Gurevich. Naming can be mainly MiG-21 (from the version of the PFM hereinafter), the MiG-23 (all versions) and MiG-25. Furthermore, the aircraft OKB Mikoyan Gurevich seat KM-1 is used, for instance bombers Tupolev Tu-22M3 Backfire. The only disadvantage of seat KM-1 is the absence of the overhead deflector thereby is prevented eject through the closed canopy.

    Technical description:
    (described is the modified seat KM-1 of fighter aircraft Mikoyan Gurevich MiG-25)

    The basis of seat KM-1 is made up of vertical structures made of maraging steel consisting of two girders and five cross. On this structure, it is in the top of the fixed padded headrest containing an emergency walkie-talkie to the pilot and the first aid kit.
    Under the záhlavníkem is placed profiled ironclad shield resistant to the intervention of the projectiles in caliber 7,65 mm roll pilotova back. On the shield are placed the hinges for fixing the back of the glider pilot and the rescue chute. This parachute has a separate restraint straps to which is the pilot in the seat, clamped and used as a cause the reserve parachute to the harness after the separation of the seats from the pilot in case of ejection. Parachute pouch contains, inter parachutes and two small cylinders for the pilot (oxygen) and to pressurize the suit (the air). These bottles are placed on the padded front part of the parachute of the capsule forming at the same time, the head restraint of the back of the pilot. Along the sides of the shield are placed two hinges with utahovacími rollery for the main restraint belts of the seat.
    The lower part of the seats to form the profiled metal bath in which is located the emergency equipment the pilot (additional food benefits, survival equipment). Its upper cover is formed of soft metallic cover. Along the sides of the front and sides of the tub are placed a fixed limiter of the movement of the pilot when despite issuing the ejection containing the controls of the seat. A true limiter is additionally complemented by a simple timer KPA-4, which ensures the correct functionality and timing of the katapultážní sequence. Energy timer during the flight, takes away from the onboard network of the aircraft and after despite issuing the ejection is provided from a small battery located on the right side of the bath seats. At the forefront of the tubs and the seats are placed footrests with stirrups to capture the foot while despite issuing the ejection. In the midst of the front part are placed handrails running katapultážní sequence
    Other elements on the seat are no longer placed directly on the supporting structure of the seat. Under the dorsal shield is placed a rod with a manipulator and a control device for the tilting of the consumer rozhozu hands when despite issuing the ejection. These limiters are located at the ends of the load bars. The rear side of the load bearing structure carries the main and backup stabilizing parachute and the guide tube of the seat with katapultážní pyropatronou in its cavity. After her lower hand are placed rychlosvorky the heating of the suit of the pilot and the oxygen and air supply of the suit. On the upper side of the structure is placed sensor tracking the delivery of the canopy and apparatus for the transfer commands to odhozu cover from the timer KPA-4 to the pyrotechnic system odhozu of the canopy.

    Katapultážní the sequence of seat KM-1:

    1)the Pilot has fold label of the helmet and the legs of the signed attached in třmenech on the footpegs, there is a retraction at the initiation of the grip katapultážní seats (the pilot is instructed to keep hands on the katapultážních madlech).
    2)the Timer KPA-4 is activated, are catching up with the main restraint straps, fold the limiter rozhozu hand, occurs by pressurizing the suit, the timer sends a command to trigger the pyrotechnic system odhozu the canopy (if it is not pushed, the signal is constantly repeated and eject it in the meantime blocked).
    3)the Canopy is discarded and zažíhá is pyropatrona katapultážního system seats while the development of the telescopic tube the seat leaves the cockpit (rychlosvorky are rozpojeny and the power supply and the oxygen system shall pass to the autonomous systems integrated in the seat.
    4)Pyropatrona burned out and the opening of the main stabilizing parachute. In the event that his opening does not occur, it opens up the backup stabilization parachute.
    5)the Seat is stabilized and zbržděna to a safe speed. Leads to the release of the main lashing straps and the pilot from the seat becomes detached with the parachute casing on the back and the emergency equipment of the headrest and the seat-tub seats, hanging on the rope under the other.
    6)Automatically opens the personal parachute of the pilot (the opening of the rescue chute in the case of nerozvinutí or neotevření the main parachute).

    the Parameters of the seat in terms of height and speed of ejection:

    (The speed of ejection / the height of the ejection)

    0-270km/h / 0 m
    270-600km/h / 100 m
    >600km/h 500 m

    Vlavo na obrazku je otvoreny mechanizmus KPA-4, ktory riadi cinnost sedacky podla rychlosti a vysky katapultaze.
    Nad nim pyromechanizmus odstrelenia tyce 1. stabilazacneho padaku, pod nim ( s napisom PV-50 ) je pyromechanizmus zapalenia raketoveho motoru. Vpravo je pyromechanizmus ramenneho pritiahnutia. (daco podobne uz mame aj v autach).
    Centralne cierne teleso je raketovy motor v nom je umiestneny aj KSM horna cast vystupuje hore(ako pisal Alchymista) uplne dole je vidiet dve trysky raketoveho motora.

    In the postings is chýb viac, ako is healthy.
    - in záhlavníku nie su uh, pressure flaše, the only pressure flaša on pilotný oxygen is in the seat/seat cushion, there is aj pilotný parachute and núdzová dose
    - the pilot does not have the "záložný" parachute - the very pilotný parachute is núdzovka, dropping rýchlejšie ako away
    - all the timers in KM-1 and KM-1M are mechanical, similar to older airborne, got prívody air zo snímačov static and dynamic pressure
    - for čalúnením chrbtovej opierky nie is well, the parachute, the nie is there anything, opierka is of aluminum plate, so on the "nepriestrelnosti" sa can't even speak in, home role is to contribute support to the pri what, are we sitting and zakryť mechnizmy seats
    - vôbec nie it is spomenutý rocket motor seats, as it gives the properties of h=0 v=0. Engine sa spúšťa already during the movement of the seats on the hlavnom teleskopickom vystrelovacom mechanizme, when the sa the bottom of the seat rises up about a meter above the floor kabíny (preto to pilot neofúkli žeravé the products of combustion of the engine discouraged from stien, flooring and making walls kabíny)

    Odporúčam zohnať with the currently legislation on seat KM-1M, or at least a good description..

    Děkuji za kritiku příspěvku. O těchto rozdílech vím. Při popisu jsem vycházel z popisu sedačky KM-1 z letounu MiG-25 (www.ejectionsite.com) což jsem ale zapoměl zmínit v příspěvku a za to se omlouvám. Tato sedačka má oproti standartní sedačce KM-1 a KM-1M rozdíly v rozmístění jednotlivých komponent s ohledem k nutnosti katapultáže ve velké výšce. Proto je odlišné umístění tlakových lahví a tyto mají větší kapacitu protože se předpokládá jejich delší využívání (pilot se od sedačky odděluje později). Taktéž je zde odlišné rozmístění padáků,které jsou v zádovém pouzdře protože sedací část využívají jiné komponenty. Mechanický časovač KPA je pro správnou funkci a nezámrznost ve velké výšce vyhříván-proto ta baterie.Protože MiG-25 nemá dostatečnou pancéřovou ochranu kabiny v zadní polosféře,je sedačka pancéřována. Celkově je sedačka poněkud rozměrnější než standartní KM-1 a KM-1M.

    Bohužiaľ, na uvedenej adrese som nič o sedačke KM-1 pre Mig-25 nenašiel, takže by to chcelo presnejší link. Celkom by ma to zaujímalo, ako bola upravená (pokiaľ bola upravovaná, pretože bežne sa uvádza, že v Mig-25 bola štandrdná KM-1M)
    Ale väčšia zásoba kyslíku sa mi nezdá z iného dôvodu - pilot mal germák, takže únik maskou bol vylúčený a štandardná "fľaša" vydrží cca 20 minút, čo postačuje na sklesanie do bezpečnej výšky. Navyše by nastal problém, kam so stabilizačným a brzdiacim padákom sedačky.

    Teď nemám moc času ale link pohledám a hodím jej sem. Co se láhve týče tak jak jsem koupil tak prodávám. Nejsem ani letecký mechanik ani pilot takže skutečnou sedačku v oku nemám Wink . Každopádně tvůj názor se mi zdá dosti logický. Možná že šlo jen o větší množství do zálohy.


    Jinak co se týče MiGu-25 tak se uvádí nejen KM-1M ale i KM-1 a to především u starších verzí.

    Quote - Alchymista :

    V príspevku je chýb viac, ako je zdravé.


    - vôbec nie je spomenutý raketový motor sedačky, ktorý jej dáva vlastnosti h=0 v=0. Motor sa spúšťa už počas pohybu sedačky na hlavnom teleskopickom vystrelovacom mechanizme, keď sa dno sedačky zdvihne zhruba o meter nad podlahu kabíny

    v clanku je strasne vela chyb az nezmyslov, napr. min. rychlost nie je nula ale 130km/hod.
    Raketovy motor sa zapaluje po 850 mm pohybu sedacky. Trysky raketoveho motora su na stranach v spodnej casti (motor je zvisle v centralnej nosnej casti sedacky) a su natacane podla hmotnosti pilota, presnejsie podla vysky, s pohybom vany sedacky sa natacaju trysky, pohyb vany je asi 120mm, ak sa nepletiem. (je to uz 15 rokov co na nich nerobim)

    Na obrázku je pristroj PPK-2P-405, ktorý slúži na otvorenie záchranného padáku pilota. Pristroj je uvádzaný do činnosti 2 m dlhým lankom pri odpojení pilota od sedačky.
    Padák je možné otvoriť aj ručne.
