    Study Notes

    Ground Control Equipment (GCE)

    • GCE is a key component of the FLAME anti-tank weapon system.
    • It is a hybrid, second-generation weapon that utilizes SACLOS (Semi-Automatic Command to Line of Sight) guidance.
    • The GCE consists of three primary parts:
      • Sight (9W-119M1)
      • Optical and Mechanical Coordinator (OMC)
      • Electronic Pack
    • The Sight is a periscopic telescope with several functions:
      • Observing the target area
      • Selecting a target
      • Laying the launcher on the target
      • Tracking a moving target
      • Receiving infrared (IR) rays from the missile

    Sight 9W-119M1

    • The Sight contains a mirror positioned at a 75-degree angle to the line of sight (LOS).
    • The mirror is used to track the missile’s infrared (IR) beam using transparent and opaque radials.
    • The frequency of the current produced by the Sight is 22,500 Hz when the missile is on the LOS.
    • Variations in frequency help determine the missile's angular deflection from the LOS.

    Optical and Mechanical Coordinator (OMC)

    • The OMC is responsible for scanning the target area.
    • It uses a stabilized circuit and frequency modulation to ensure precise tracking and missile guidance.
    • The OMC's scanning frame has a 1:1 correspondence with the missile's flight path.

    Electronic Pack

    • The Electronic Pack is the brain of the FLAME system.
    • It receives electrical voltage from the OMC, generates correction signals to guide the missile onto the LOS, and sends these commands to the missile via a wire.
    • It is composed of eleven Printed Circuit Boards (PCBs) that perform various tasks including:
      • Coordinator unit
      • Compensator unit
      • Coordinate converter unit
      • Missile battery voltage generator (MBVG)
      • Power supply unit (PSU)
      • Relay
      • Stabiliser unit
    • The Electronic Pack has several key functions:
      • Launches the missile upon reaching the correct junction unit battery voltage.
      • Adjusts the OMC motor speed to ensure correct scanning frame speed.
      • Transmits time signals for control circuit changes.
      • Receives angular deflections from the Sight and OMC.
      • Converts electrical signals into linear coordinates.
      • Prepares polar command signals for the missile.
      • Delivers the command signals to the missile through the wire.

    FLAME Launcher

    • The FLAME launcher is crucial for firing the FLAME missile.
    • It contains various parts responsible for launching and providing the initial propulsion for the missile.
    • Parts include:
      • Gas Generator
      • Blast Tube
      • Piston
      • Launch Tube
      • Junction Unit

    Junction Unit

    • The Junction Unit facilitates the communication between the launcher and the missile.
    • It transmits electrical current to initiate the missile's operation.
    • Additionally, it provides power to the launcher and transmits command signals from the launcher to the missile.

    FLAME Missile

    • The missile is a crucial part of the FLAME weapon system.
    • It consists of a head and a vehicle.
    • The head includes the warhead and the fuze.
    • The vehicle houses the motor, rear section, and the wire spool.
    • The warhead utilizes a Hollow Charge principle to destroy armor plating upon impact.

    Thermal Batteries

    • Thermal batteries are used to provide a power supply to the FLAME weapon system.
    • The batteries consist of 14 cells connected in series.
    • They contain an electrolyte, a powder charge, and electrodes.
    • When a current activates the electrical igniter, it burns the powder charge, melts the electrolyte, and allows for the flow of electrons, generating current.
    • Two thermal batteries are used for the FLAME weapon system:
      • Junction Unit Battery (JUB)
      • Missile Battery

    Pre-Launch Operations

    • These operations occur from the time the trigger is activated until the missile is launched.
      • The JUB activates within 0.3 seconds of receiving current from the trigger mechanism.
      • The JUB provides the first ignition pulse for the missile battery and the gyroscopic assembly.
      • It also provides power to the launcher components.
      • The missile battery activates after 0.3 seconds of receiving current from the JUB.
      • The missile battery provides power to the missile decoder, bulb, photodiode, and the fuze initiator.

    Technical Maintenance

    • Regularly scheduled maintenance is essential to ensure the optimal function and longevity of the FLAME launcher.
    • The weapon system goes through different levels of inspections, including:
      • Check Inspection
      • Routine Maintenance
      • Technical Maintenance
      • Seasonal Maintenance

    Limitations of the FLAME Weapon System

    • The FLAME weapon system has specific limitations:
      • Long Time of Flight
        • This can impact the effectiveness of the weapon, especially against targets moving quickly or at a great distance.
