An aerodynamic airflow deflecting device for a landing gear retracting into a housing of an aircraft, comprising at least one element for closing the housing that is, through the action of a control device, able to occupy a position for shielding at least a part of the landing gear against the aerodynamic airflow, thus constituting a noise reducing aerodynamic device. The closing element can in particular include at least one trap door element that is, through the action of the control device, movable between a first position for closing the housing, a second position allowing the landing gear to exit and a third position constituting said shielding position.

The invention claimed is: 1. An aerodynamic airflow deflecting device for a landing gear that is retractable into and extendable from a housing of an aircraft, the aerodynamic airflow deflecting device comprising: a closing assembly operably coupled to the housing, the closing assembly being shiftable, by a control device, between a first position such that the housing is closed, a second position to allow the landing gear to extend from the housing, and a third position opposing an aerodynamic airflow such that in the third position, the closing assembly shields at least a part of the landing gear when the landing gear is in an extended, landing position, and wherein the closing assembly comprises two flaps operably coupled to a jig articulatable about a first transverse axis of the aircraft, wherein the first flap is pivotable about a first longitudinal axis located on a first side of the housing, and the second flap is pivotable about a second longitudinal axis located on a second side of the housing, and wherein the two flaps are inclined in front of the lowered landing gear when the closing assembly is in the third position, and wherein the articulated jig comprises a U-shaped structure with a central branch and two lateral branches, the first flap being coupled to one of the two lateral branches, and the second flap being coupled to the other lateral branch, wherein each lateral branch of the two lateral branches of the jig comprises a lateral panel forming a vertical longitudinal fairing. 2. The device according to claim 1, wherein the central branch of the jig is equipped with means for articulating the jig about the first transverse axis, and wherein the two lateral branches are each equipped with means for articulating the flaps about the first and second longitudinal axes. 3. The device according to claim 1, further comprising a first pair of actuating jacks, each actuating jack of the first pair being associated with one of the two flaps, a first end of each actuating jack of the first pair being operably coupled to the associated flap and a second end of each actuating jack of the first pair being operably coupled to the jig. 4. The device according to claim 3, wherein each actuating jack of the first pair of actuating jacks is operably coupled to one of the lateral panels, and wherein each actuating jack of the first pair of actuating jacks is adapted to direct the motion of the associated flap about the corresponding lateral branch. 5. The device according to claim 4, further comprising a second pair of actuating jacks, each actuating jack of the second pair being associated with one of the two lateral panels, a first end of each actuating jack of the second pair being operably coupled to the associated lateral panel and a second end of each actuating jack of the second pair being operably coupled to the aircraft structure, wherein each actuating jack of the second pair of actuating jacks is adapted to direct the movement of the jig about the first transverse axis.
