Patent

CA 2523184

The invention relates to a light plane comprising an engine arranged on the nose and provided with a tractor airscrew, and a cabin that is arranged behind the engine and is wide enough for two adjacent passenger seats. A central tube (1) with a 200 mm diameter extends forwards towards the engine and to the rear at least behind the front edge of the lateral rudder and elevator control. Everything else is constructed around said tube. A square profiled element (12) is transversally guided edgeways beneath the central tube (1) and is rigidly connected to the same in a positively engaged manner. An upwardly projecting tube bend (11) which arches over the length of the square profiled element is fixed to the rear side of the square profiled element (12) with the ends thereof. The level of a virtual plane cabin floor is defined above the square profile (12). The free space above said floor is orthorhombic: at least 190 cm long, at least 45 cm wide, and at least 40 cm high.

La présente invention concerne un avion léger qui présente un moteur disposé à l'avant et comprenant un hélice de traction, et à l'arrière une cabine dont la largeur permet à deux passagers de s'asseoir côte à côte. Un tube central (1) de 200 mm de diamètre s'étend vers l'avant jusqu'au moteur et vers l'arrière au moins jusqu'à l'arrière du bord avant du gouvernail de direction et de profondeur. Tout le reste est monté autour de lui. Un profilé tétragonal (12) est disposé sur chant transversalement en-dessous du tube central (1) et relié à celui-ci par liaison de forme de façon à résister à la torsion. Sur la face arrière du profilé tétragonal (12) est fixé au niveau de ses extrémités un tube arqué (11) qui est incurvé sur la longueur du profilé tétragonal (12) et dépasse vers le haut. Au-dessus du profilé tétragonal (12) est défini le niveau d'un plancher de cabine plan virtuel. L'espace libre au-dessus de ce plancher correspond à un espace orthorhombique d'au moins 190 cm de longueur, d'au moins 45 cm de largeur et d'au moins 40 cm de hauteur.
