The invention relates to an automatic takeoff method for an aircraft with a flexible airfoil, comprising a carriage suspended by rigging lines from an airfoil. According to said method: - said carriage is provided with an autopilot controlling actuators that control said rigging lines; - said airfoil is provided with an airfoil attitude sensor, comprising a biaxial accelerometer and a biaxial rate gyro, capable of defining the position of an airfoil reference frame in relation to the ground, and means for communicating with said autopilot; - during takeoff, information is received from said airfoil attitude sensor and transmitted to said autopilot for the purpose of controlling said actuators. The invention also relates to an airfoil for the implementation of said method, comprising an airfoil attitude sensor with an inertial unit with a biaxial accelerometer and a biaxial rate gyro, and means for communicating with an autopilot. The invention further relates to an aircraft comprising such an airfoil.

L'invention concerne vin procédé de décollage automatique d'un aéronef à voilure souple, comportant un chariot suspendu par des suspentes à une voile. Selon ce procédé : - on équipe ledit chariot d'un autopilote commandant des actionneurs agissant sur lesdites suspentes; - on équipe ladite voile d'un capteur d'attitude voilure, comportant un accéléromètre deux axes et un gyromètre deux axes, apte à définir la position d'un référentiel voile par rapport au sol, et de moyens de communication avec ledit autopilote; - lors du décollage, on récupère des informations en provenance dudit capteur d'attitude voilure pour les communiquer audit autopilote pour commander lesdits actionneurs. L'invention concerne une voile pour la mise en oeuvre de ce procédé, comportant un capteur d'attitude voilure avec une centrale inertielle avec un accéléromètre deux axes et un gyromètre deux axes, et des moyens de communication avec un autopilote. L'invention concerne un aéronef comportant une telle voile.
