Claim Text:
1. A lift and propulsion device for a vertical or short take-off and landing aerodyne, by the effect of lift obtained by blowing an airflow produced by an airflow generator over lift airfoils connected to a support structure, the device comprising two substantially rectilinear longitudinal airfoils disposed on either side of said support structure and substantially parallel to a roll axis of the device, said two longitudinal airfoils being symmetrical to each other with respect to a plane defined by said roll axis and a yaw axis, wherein each longitudinal airfoil has a length along said roll axis which is at least equal to the sum of the blower diameter for the total amount of blowers, wherein generatrices of the lifting surfaces of said longitudinal airfoils are substantially rectilinear and substantially parallel to said roll axis or slightly inclined to said roll axis, and wherein said airflow generator comprises at least one blower having an axis which is vertical or at a maximum angle of substantially 30° to said yaw axis, mounted in said support structure, with a maximum diameter that corresponds to an extreme rotation diameter of blower blades, and which is more than 50% of the width of said support structure.
