FOLDED AERODYNAMIC SURFACE OF AIRCRAFT Russian patent published in 2019 - IPC F42B10/14 

FIELD: aviation; astronautics.

SUBSTANCE: invention relates to aviation and rocket technology, starting from the transport and launch container. Foldable aerodynamic surface of the aircraft comprises a panel and a suspension assembly to the body of the aircraft, which form a hinged connection with the help of a folding axis, a panel opening mechanism and the mechanism of fixing the panel in the open position in the form of spring-loaded fingers with a conical part at the end. Suspension assembly is made in the form of a flange with two eyes and a central protrusion with a groove located in the response cutouts in the panel. In the shelves of the central protrusion are made coaxial cylindrical holes, the axis of which is perpendicular to the plane of the chords of the panel in the open position. In the groove placed liner with two pushers pivotally connected to the liner and its ends are located in the holes of the lugs of the suspension assembly to interact with spring-loaded fingers of the fixation mechanism, which are installed in the panel on the outer sides of the lugs of the suspension assembly with entering the response holes of the lugs in the open position of the panel. Shaft is installed in the hole of the central protrusion, the middle part of which is located in the through hole made in the liner, ensuring its rotation when the shaft is rotated.

EFFECT: invention is directed to improving the reliability of fixing the aerodynamic surface after deployment.
