Abstract: A spaceplane suitable for aeronautical flight comprising a body and a wing defining a lower airfoil surface in addition to attitude control means that comprise one or a plurality of shutters disposed under the lower airfoil surface of same and maneuverable between a stowed position and an inclined extended position for aerodynamic braking during the transition from a phase of space flight to a phase of aeronautical flight of the aircraft.

Abstract: A device for mounting and supporting a generally cylindrical or tapered tank, having a main axis X, that includes a pair of first retaining rods for retaining the tank along a vertical axis Z on each of a first and second end of the tank, a second retaining rod for retaining the tank along a horizontal axis Y, perpendicular to the main axis, on the first end of the tank, and a third retaining rod for retaining in a ball-and-socket joint, the means being located around the vertical axis and connected to the second end of the tank.

Abstract: The invention concerns a tank retainer for retaining a tank in the fuselage of an aircraft which includes, between the tank and a frame rigidly connected to the fuselage of the aircraft, a hinged retaining means and a fastening rod on which said hinged retaining means is mounted. Advantageously, the hinged retaining means is intended to be connected to a rear end of the tank and the fastening rod is suitable for being mounted on the frame rigidly connected to the fuselage of the aircraft and, preferably, the hinged retaining means comprises a ball joint.
