摘要

1. Device to assist the control system of a flying wing, in particular by modifying its wing surface distribution, which flying wing comprises a structure on which a wing surface (2) is disposed and from which there are suspended a cell (3) by means of a mast (4) and a control bar (5), the said structure comprising two rectilinear elements (6, 7) forming between them an angle referred to as the nose angle, and a keel (8) disposed substantially along the internal bisector of the said angle, said elements and keel being articulated in relation to one another at the vertex of the said angle or nose (9), the said cell (3) being rotatably mounted on the keel, the structure also comprising two transverse bars (10, 11) each mounted so as to be movable on one of the rectilinear elements at one of their ends, to maintain the said wing surface spread out, characterized in that the transverse bars (10, 11), at one of their ends, are rotatably mounted to one of the rectilinear elements (6, 7) and, at their other end, are mounted on one end of a plate (12), which is itself rotatable about a vertical pivot (13) solid with the keel, which plate cooperates with means for suspending the cell (3) comprising two vertical cheeks (15, 16) disposed on either side of the said keel (8) and solid with a support (17) which can turn about the latter about its axis.
