Variant aircraft is an aircraft that can change its shape during flight to obtain different aerodynamic characteristicstocope with different flight environments and complete different flight tasks. The wing with variable camber at the trailingedge, as a relatively easy deformation method in structure, has attracted much attention in the research field. In order torealize smooth and flexible deformation of wing with variable camber at trailing edge, distributed driving mode must beadopted. In this paper, a multi-section distributed driving device based on fiber reinforced flexible cavity with internal pressure is proposed. The influence of fiber braided sleeve on the flexible cavity with internal pressure, the internal structure layout design of the driving device, the connection between components in the device and the connectionbetween the device and the wing are studied. The driving device has been applied to a wing with variable trailingedgecamber, and satisfactory results have been obtained. It is proved that the driving device can improve the drivingreliability on the basis of meeting the driving requirements, so that the whole trailing edge variable camber wingcanmaintain good continuity during deformation.
