Abstract (en)
[origin: FR2652559A1] The subject of the invention is a retractable or withdrawable thruster using a trapezoidal device with deforming rotation generating a rectilinear movement inside a well. The thruster is retractable or withdrawable and is composed of a casing (1) fixed in leaktight manner on mating surfaces, onto a well (2) forming an integral part of the structure (3) of the craft. Inside this casing (1) are folded two arms (4) and (5) which pivot asymmetrically, a motorised base part (10), a stirrup piece (yoke) (17) and a helical assembly. The two arms (4) and (5), on the one hand, are pinned at (6) and (7) on the casing (1) and, on the other hand, at (8) and (9) on the stirrup piece (17) secured to propulsion base part (10). Under the manual or mechanical action (X) or (Y) exerted on the lever (12) secured to the arm (4) via the shaft (6), the said arm (4) in compound rotation with the triangulation arm (5) orders the deformation of the trapezium obtaining a rectilinear movement along the axis (AZ) of the base part (10) at its centre (11). <IMAGE>
