Title (EN) FAST DETECTOR OF WIND GRADIENT
(FR) DETECTEUR RAPIDE DE GRADIENT DE VENT
Abstract: front page image
(EN)Process for fast detection of a wind gradient. This process uses the relationship between the aerodynamic slope a, the total slope T and the anemometric speed V, relationship which may be formulated as follows: (FORMULA) wherein s is the laplacian operator, A is a constant or zero value, in case of normal night without any disturbances, and which rises in case of a wind gradient, head wind becoming down wind, and Vsel is an instruction value. Said value A is mixed with a representative value of the aerodyne capacity to overcome a wind gradient, so as to obtain a composite signal compared to a reference value. The invention may be used during the approach phase of an aerodyne.
(FR)Procede pour la detection rapide d"un gradient de vent, qui utilise la relation existant entre la pente aerodynamique a, la pente totale T et la vitesse anemometrique V, relation pouvant etre de la forme (FORMULE) dans laquelle s est l"operateur de Laplace, A est une valeur qui est sensiblement constante ou nulle, en cas de vol normal sans perturbations, et qui croit dans le cas d"un gradient de vent, vent avant devenant vent arriere, et Vsel est une valeur de consigne. Cette valeur A est melangee a une valeur representative de la capacite de l"aerodyne a surmonter un gradient de vent de maniere a obtenir un signal composite compare a une valeur de reference. L"invention peut etre utilisee au moment de la phase d"approche d"un aerodyne.
