Patent

CA 2403269

Disclosed is an aircraft (101), configured to have a wide range of flight speeds, consuming low levels of power for an extended period of time, while supporting a communications platform with an unobstructed downward-looking view. The aircraft (101) includes an extendable slat (205) at the leading edge of the wing (103), and a reflexed trailing edge. The aircraft comprises a flying wing (103) extending laterally between two ends and a center point. The wing (103) is swept and has a relatively constant chord. The aircraft (101) also includes a power module configured to provide power via a fuel cell (131). The fuel cell (131) stores liquid hydrogen as fuel, but uses gaseous hydrogen in the fuel cell (131). A fuel tank heater is used to control the boil-rate of the fuel in the fuel tank. The aircraft (101) of the invention includes a support structure including a plurality of supports, where the supports form a tetrahedron that affixes to the wing (103).

L'invention concerne un aéronef, conçu pour avoir une vaste gamme de vitesses de vol, qui consomme de faibles niveaux d'énergie pendant une longue période, tout en portant une plate-forme de communications présentant une vue plongeante libre. L'aéronef comporte un bec de sécurité extensible sur le bord d'attaque de l'aile et un bord de fuite réfléchi. L'aéronef comprend une aile volante s'étendant latéralement entre deux extrémités et un point central. L'aile, balayée, présente une corde relativement constante. L'aéronef comporte également un module de puissance qui fournit de l'énergie par le biais d'une pile à carburant. Cette dernière stocke de l'hydrogène liquide en tant que carburant, mais utilise de l'hydrogène gazeux. Un réchauffeur de réservoir de carburant est utilisé pour réguler la vitesse d'ébullition du carburant dans ledit réservoir. L'aéronef comprend enfin une structure porteuse comportant plusieurs supports qui forment un tétraèdre appliqué à l'aile.
