An wing-in-ground-effect craft (11) having a loaded canard forewing (13) and a main forward delta configuration wing (15) attached to fore (17) and mid (19) sections of a body (21) respectively. The body (21) is formed with an integral planning hull (23) for amphibious applications, extending rearward to a tail section (25) which incorporates a ducted fan (27), and a vertical stabiliser (29). Rudder (31) is located in the exhaust of the ducted fan (27) for steering the craft (11), and serves as a stator to reduce spiral induced in the airflow exiting the duct (27). The canard forewing (13) has about 12% of the area of the main wing (15), and has inner portions (35) having a dihedral configuration disposed at a first angle of inclination from the vertical of 68~ (equating to a dihedral angle of 22~), and outer portion (37) disposed at a first angle of inclination from the vertical of about 91~ (equating to an anhedral angle of about 1~). The inner portions (35) have an angle of attack of 7.5%, while the outer portions (37) have an angle of attack of 4.5~. The main wing (15) has a flat to slightly anhedral configuration and an angle of attack of from 4~ to 4.5~. The main wing (15) incorporates a pontoon float (39) attached on the outer end of each main wing (15). The canard forewing (13) has control surfaces in the form of elevons (41) attached behind the inner portions (35).

L'invention concerne un véhicule à portance dynamique (11) possédant une aile antérieure canard chargée (13) et une aile principale avant à configuration delta (15) fixée respectivement aux sections antérieures (17) et médianes (19) d'un corps (21). Le corps (21) est formé d'une carène planante intégrée (23) destinée à des applications amphibies, s'étendant vers l'arrière à une section de queue (25) qui comporte une soufflante canalisée (27), et un stabilisateur vertical (29). Le gouvernail (31) est situé dans l'échappement de la soufflante canalisée (27) afin d'orienter le véhicule (11), et sert de stator afin de réduire la spirale induite dans le flux d'air sortant de la canalisation (27). L'aile antérieure canard? ¿(13) comporte environ 12 % de la zone de l'aile principale (15), et des parties internes (35) à configuration dièdre disposées à un premier angle d'inclinaison à partir de la verticale de 68· (équivalent à un angle dièdre de 22·), et des parties externes (37) placées à un second angle d'inclinaison à partir de la verticale d'environ 91· (équivalent à un angle dièdre négatif d'environ 1·). Les parties internes (35) possèdent un angle d'attaque de 7,5·, alors que les parties externes (37) possèdent un angle d'attaque de 4,5·. L'aile principale (15) comporte une configuration plate ou sensiblement dièdre négative et un angle d'attaque compris entre 4 et 4,5·. L'aile principale (15) comprend un ponton flottant (39) relié à l'extrémité externe de chaque aile principale (15). L'aile antérieure canard (13) possède des surfaces de commande en forme d'élevons (41) fixées à l'arrière des parties internes (35).
