Slats are part of the aircraft wing mechanization and are responsible for the regulation of carrying properties. Two-chamber control system. Adjustable two independent controllers calculators. Right and left slat is divided into four sections. Each 2 suspended on rails. The electric drive moves the slats. The actuator is located in the center section, and a block of two electric motors, which are interconnected gear. Manual transmission transmits the torque from the drive.
Transmission begins on the CPU and extends over the entire surface of the slats along the wing spar. The bottom hatches closed-type removable tapes and fastened with screws.
It consists of intermediate gears and driveshafts:
In one gear group to shift the motor shafts.
Two bevel gear in the CPU with the left and right sides: for the variability of the direction of transmission in the area of electric drive to the side ribs.
On drives with planetary gear (RFP) comes with the rotation shaft. IFR rotates the pinion, thereby moving the racks on rails slats. When they are pushed into the rails clean glasses (special burial) in the front spar or wing box. The emphasis is attached to the end of each track. If it is out of lock, then it would exceed the optimal value of torque. Thus, the work clutch in the corresponding RFP and, therefore, begin locking.
In addition, in the transmission includes a dual sensor assembly error and the brake mechanism. They are at the end of the transmission. The signals are compared between the sensor error rates left and right consoles.
Friction brake acts as a backstop rotation transmission in cases where:
Refuse 2 drive motor.
There will be a mismatch of the current and target position of the slats.
In case of loss, which will lead to an asymmetric position of the slats.
In the event that only one engine fails, the system will continue to work, but with reduced almost twice the speed of movement.
