AIRCRAFT WITH A CONTROL DEVICE

An aircraft (F) with aerofoils (1a, 1b) comprising a main wing (M) and at least one control flap (S) that is arranged so as to be adjustable relative to the aforesaid, and comprising at least one adjustment flap (K), with the aircraft comprising: - an actuator (21 ) for operating the at least one control flap (S), as well as a sensor device (24) for acquiring the set position of the control flap (S), - at least one arrangement (15; 15K) of flow-influencing devices (16; 16K), which extends on the main wing (M) and/or of at least one adjustment flap (K) of each aerofoil (M; 1a, 1b), for the purpose of influencing the fluid that flows over the surface segment (10; 10K) and - at least one arrangement of flow-state sensor devices (17; 17K) for measuring the flow state on the respective segment (10; 11a, 12a; 11b, 12b), - a flight control device (50) which on the input side is functionally connected to the sensor device (24) for acquiring the set position of the control flap (S) and to the flow-state sensor devices (16; 16K) and which flight control device (50) for the purpose of transmitting actuating commands (50a) on the output side is functionally connected to the actuator (21) and the flow-influencing devices (16;16K), - a flight-state sensor device (40) functionally connected to the flight control device (50) for transmitting flight states, wherein the flight control device (50) comprises a function that for the purpose of optimising local lift coefficients on the aerofoil depending on the flight state carries out a selection of the flow-influencing devices (16; 16K) that are to be operated. L'invention concerne un aéronef (F) à surfaces portantes (1a, 1b) comprenant une aile principale (M) et au moins un volet de commande (S) qui est conçu de manière à être réglable relativement à ladite aile, et comprenant au moins un volet de réglage (K), l'aéronef comprenant: -un actionneur (21) pour actionner le ou les volets de commande (S), ainsi qu'un dispositif de détection (24) pour acquérir la position prédéfinie du volet de commande (S), -au moins un agencement (15, 15K) de dispositifs d'influence sur l'écoulement (16, 16k), qui s'étend sur l'aile principale (M) et/ou d'au moins un volet de réglage (K) de chaque surface portante (M; 1a, 1b), afin d'influer sur le fluide qui circule sur le segment de surface (10; 10k) et -au moins un agencement de dispositifs de détection d'état d'écoulement (17; 17k) pour mesurer l'état de l'écoulement sur le segment respectif
