Abstract
A displayable appendix linked to the structure of a space vehicle movable about an articulation axis from a stored position along the structure of the space vehicle to a display position by a control mechanism with abutments on the appendix and on the structure of the space vehicle so distributed and located as to prevent warping or distortion of the articulation axis and the control mechanism by exerting upon the appendix bending prestresses which are reduced near the articulation axis to a pure prestress torque tending to cause the appendix to move to the display position and temporary forces obtained from use of the abutments to hold the displayable appendix in the stored position during launch of the space vehicle.
