Abstract: An aircraft wing has a main wing element with a spar and a leading edge rib supported by the spar, a high lift device movably mounted to the main wing element, and an actuation mechanism with a drive shaft and a gear train. The gear train has a drive cog carried by the drive shaft, an actuator cog coupled to the high lift device, and one or more intermediate cogs mounted to the rib and coupled in series with the drive cog and the actuator cog so as to transmit torque from the drive cog to the actuator cog which moves the high lift device between a retracted position and an extended position in which the high lift device increases the camber of the wing. Sizes of the cogs in the gear train are selected so that the drive shaft rotates at a higher rate than the high lift device.

Abstract: An aircraft wing comprising a main wing element with a spar and a leading edge rib which is supported by the spar and extends forward of the spar; a high lift device which is movably mounted to the main wing element; and an actuation mechanism comprising a drive shaft and a gear train. The gear train comprising a drive cog which is carried by the drive shaft, an actuator cog which is coupled to the high lift device, and one or more intermediate cogs which are mounted to the rib and coupled in series with the drive cog and the actuator cog so as to transmit torque from the drive cog to the actuator cog which moves the high lift device between a retracted position and an extended position in which the high lift device increases the camber of the wing. The sizes of the cogs in the gear train are selected so that the drive shaft rotates at a higher rate than the high lift device.

Abstract: A cutting tool has: a rotatable hollow tube with an inlet at a distal end of the tube and a cutting edge at the perimeter of the inlet, the tube being arranged so as to rotate when in use so as to cut a work piece with the cutting edge; and an auger housed within the hollow tube, the auger being arranged so as to rotate when in use so as to feed cut material from the inlet along the hollow tube, wherein a distal end of the auger is set back from the cutting edge of the tube.
