Lift and propulsion device, and heavier-than-air aircraft provided with such a device

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 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.

A vertical or short take-off and landing aerodyne, comprising a support structure supporting a lift and propulsion device comprising an airflow generator and 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 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, said device being supported in an upper part of said support structure, which is fitted out, in a lower part, as a nacelle accommodating a driving system and disposed between said two longitudinal airfoils of said device.
