Patent

CA 2758461

The invention relates to a high lift sys-tem for an airplane, comprising: one or more high lift flaps (14a, 14b); a control device (60, 160) having a control function for generating position commands for setting the adjustment state of the high lift flaps (14a, 14b); a drive device (63, 163) coupled to the high lift flaps (14a, 14b) and is designed such that it adjusts the high lift flaps (14a, 14b) between a retracted position and an extended position on the basis of control com-mands, wherein the control function creates position commands based on input values and sends them to the drive device (63, 163) for adjusting the high lift flaps (14a, 14b). The control function comprises a function for automatically retracting the high lift flap (14a, 14b) during flight, which creates a control com-mand in a flight state in which the high lift flap (14a, 14b) is in an extended position, taking into considera-tion an engine thrust and a minimal flight altitude, af-ter the high lift flap (14a, 14b) is retracted.

L'invention concerne un système hypersustentateur pour un avion, comprenant : - un ou plusieurs volets hypersustentateurs (14a, 14b), - un dispositif de commande (60, 160) avec une fonction de pilotage produisant des instructions de positionnement pour le réglage de l'état des volets hypersustentateurs (14a, 14b), - un dispositif d'entraînement (63, 163) couplé avec les volets hypersustentateurs (14a, 14b), configuré pour déplacer les volets hypersustentateurs (14a, 14b) en fonction des instructions de commande entre une position rétractée et une position déployée. La fonction de pilotage produit des instructions de positionnement sur la base des valeurs d'entrée et les envoie au dispositif d'entraînement (63, 163) pour le positionnement des volets hypersustentateurs (14a, 14b). La fonction de pilotage comprend une fonction de rétraction automatique des volets hypersustentateurs (14a, 14b) en vol qui, dans un état de vol où les volets hypersustentateurs (14a, 14b) sont en position déployée, produit, en fonction de la poussée des groupes moteurs et d'une hauteur de vol minimale, une instruction de commande qui ordonne la rétraction des volets hypersustentateurs (14a, 14b).
