  • COMMON AIRCRAFT AND UAV APPLICATIONS:

    Thrust reverser actuation system

    SEPAC has designed and manufactured the electromagnetic brakes & spring-set brakes for the world’s first electric thrust reverser actuation system. The brake holds the motor in place that controls the opening and closing of the system.

    Horizontal stabilizer trim actuation

    SEPAC electromagnetic brakes are often a critical part of HSTAs, where they prevent the motor from rotating when commanded to do so. The actuator controls the position of the horizontal stabilizer surface to attain commanded pitch position during take-off, cruise, and landing.

    Flap actuator

    SEPAC electromagnetic
    brakes are used in many flap actuation systems where they hold the
    actuator in position as commanded by the motor via the flight computer. This
    allows the plane to generate the required lift at both cruise speeds and take-off & landing speeds.

    Throttle control actuator

    SEPAC clutches are increasingly being utilized in throttle control actuators.
    Typically tooth clutches with high levels of torque and low backlash can be used
    to create an entire flight control system for unmanned and optionally-piloted
    aircraft.

    Autopilot control actuation

    SEPAC clutches are prominently featured in autopilot actuators as well in the highly successful Heli-SAS® Autopilot and Stability Augmentation System.
    These system assist in the operation of aircraft and have been documented to save
    lives from critical pilot error.

    Cargo Bay Actuators

    SEPAC designs and manufactures smaller power-off brakes that are utilized in the cargo bay rollers. These mechanized rollers efficiently move cargo pallets and
    containers without the assistance of an external source such as a forklift.

    Winch Systems

    Used in both military and commercial cargo planes, winch systems usually have
    high powered and high speed motors to facilitate pulling cargo containers into a
    secure location on the deck. Once the motor receives the command to stop,
    SEPAC brakes hold the motor in place, preventing the cable from paying out.

  • common space applications:

    Thrust vector control actuator

    SEPAC brakes hold the motor in position on some of the very latest flight control systems for launchers and space vehicles. Critical applications such as a TVCA require precision because the actuator moves the nozzle into the correct angle for reliable control of the flight path. Once moved into position the actuator motor and brake hold the nozzle steady under the most extreme vibration scenarios.

    Docking system electromechanical actuation

    SEPAC is proud to have many power-off brakes being utilized in the NASA
    docking system architecture. These brakes hold the motors on several parts of the
    system including the latch, separation and umbilical actuators. This system is a
    global standard for interfacing with the ISS and is slated to be used on many
    future space vehicles.

    Latch, Separation & Umbilical Systems

    SEPAC is proud to have many power-off brakes being utilized in the NASA
    docking system architecture. These brakes hold the motors on several parts of the
    system including the latch, separation and umbilical actuators. This system is a
    global standard for interfacing with the ISS and is slated to be used on many
    future space vehicles.

    Robotic Arms

    SEPAC’s pedigree in designing and manufacturing brakes that will work in the
    harsh conditions of space is being increasingly counted on as the population of
    satellites in space grows. Cost competitive machinery is being developed at a fast
    rate to manipulate and repair satellites while in orbit, saving an incredible amount
    of money by extending their service life.

    Solar panels

    SEPAC brakes help hold solar panels in place to acquire the most energy
    from the sun. Motors can occasionally move the position of the panels,
    depending on orbit, then letting the brake go back into its holding mode.
