Title (EN) LANDING METHOD AND SYSTEM FOR AIR VEHICLES
(FR) PROCÉDÉ ET SYSTÈME D'ATTERRISSAGE POUR VÉHICULES AÉRIENS
Abstract:
(EN) Methods are provided for operating an air vehicle, the air vehicle including fixed wings configured to provide mild stall characteristics including a post-stall regime, and a propulsion system capable of generating a controllable thrust, the thrust being variable at least between an idle thrust and a maximum thrust. During a landing maneuver, the air vehicle is caused to attain an angle of attack corresponding to said post-stall regime, and during the landing maneuver, there is concurrently generated a thrust level of said thrust greater than said idle thrust to provide a thrust vector having a thrust lift force component at landing. Corresponding control systems are also provided, and air vehicles including such control systems are also provided.
(FR) L'invention concerne des procédés pour faire fonctionner un véhicule aérien, le véhicule aérien comprenant des ailes fixes conçues pour assurer des caractéristiques de décrochage légères comprenant un régime de post-décrochage, et un système de propulsion apte à générer une poussée commandable, la poussée étant variable au moins entre une poussée au ralenti et une poussée maximale. Pendant une manœuvre d'atterrissage, le véhicule aérien est amené à atteindre un angle d'attaque correspondant audit régime de post-décrochage et, pendant la manœuvre d'atterrissage, un niveau de poussée de ladite poussée est généré simultanément et est supérieur à ladite poussée au ralenti pour fournir un vecteur de poussée ayant une composante de force de levage de poussée à l'atterrissage. L'invention concerne également des systèmes de commande correspondants, et des véhicules aériens comprenant de tels systèmes de commande.
