    Composite material integrated control surface structure with progressive decrease in rigidity and processing method thereof

    Freier Zugriff

    The invention discloses a composite material integrated control surface structure with progressive decrease in rigidity and a processing method thereof, wherein a design solution of a carbon fiber composite material integrated control surface structure is adopted; besides a control shaft and accessories thereof, the rest of the structure is carbon fiber reinforcedcomposite material; advanced optimization design technology is adopted; through several iterative calculations, the structure size design is optimized; the weight of the control surfacestructure is lightest; the rigidity of the optimized control surface structure is on the decrease progressively along an axial direction, that is, the thickness size of an internal skeleton web is on the decrease progressively towardswing tips and two sides; and the skin thickness is not the same and is on the decrease progressively towards the wing tips, thus the structure weight is further reduced; the control surface modal frequency is increased; and the control surface vibration property is improved.
