The invention relates to aircraft, and in particular to collapsible structures of the aerodynamic surfaces of unmanned aerial vehicles. Known design foldable aerodynamic surfaces, adopted as a prototype (U.S. patent for the invention №3563495, CL 244-3 .29)containing stationary and rotary parts, screw the transducer movement in a sliding cylinder shaped groove, which includes a finger rigidly connected with the rotary part of the surface to prevent rotation of the cylinder on the fixed portion of the surface placed limiter, which is a longitudinal groove made on the cylinder. Through moving cylinder finger interacting with shaped groove, turn the rotary part of the aerodynamic surface, laying out or folding it (depending on the direction of movement of the cylinder). The movement of the cylinder is a plunger (Central core). The characteristics of the prototype, coinciding with the essential features of the proposed solution are: folding aerodynamic surface contains a fixed and a hinged hinged on her rotary part, a plunger sliding within the holes of the hinge, and screw the Converter of the translational motion of the pusher into rotational motion of the rotating part and the dynamic surface, including a cylinder with helical surfaces and interacting with them the finger. In such constructions folding aerodynamic surfaces of the work coil of the transducer is not effective enough: - travel limiter on the straight groove under load does not produce a "useful work" - rotation of the movable part of the surface, but requires a significant increase in force on the plunger to overcome the frictional forces at the contact limiter and groove; - external load is small shoulders, equal to the distance from rotation axis to the points of contact of the finger with a screw surface and limiter - with a groove that also leads to increased efforts on the pusher, and the increase in the shoulders, to reduce this effort entails an increase in the transverse and longitudinal dimensions. In addition, the longitudinal dimensions of actuators (screw inverter driven progressive action) in such constructions folding surfaces are defined by a double turn coil transducer (transducer and actuator stroke) and at large angles of folding (more than 90°) significantly increase. All this leads, respectively, to increase the weight and size folding aerodynamic surfaces. The proposed technical solution run SL is blowing tasks: reduced weight and dimensions folding aerodynamic surfaces under high aerodynamic loads and large angles of opening. To achieve the technical result in folding of the aerodynamic surface, comprising a fixed and a hinged hinged on her rotary part, a plunger sliding within the holes of the hinge, and screw the Converter of the translational motion of the pusher into a rotary movement of the rotary part of the aerodynamic surface, comprising a cylinder with helical surfaces and interacting with them the finger, screw the Converter comes with a second cylinder with helical surfaces a different direction than the helical surface of the first cylinder, the cylinders are concentric to each other and prevented from mutually-and-forth movements, with one of the cylinders is connected with a fixed part of the aerodynamic surface, and the other with swivel part, the plunger is placed in the inner cylinder with the possibility of translational and rotational movements, the finger is mounted on the plunger and communicates with the helical surfaces of both cylinders through the spherical bushing, and screw the surface of each cylinder is formed with lateral surfaces of the helical grooves made on diametrically opposite sides of the cylinder shells. Distinctive features of the proposed folding aerodynamic surfaces are as follows: screw reobrazovateli comes with a second cylinder with helical surfaces other direction, than the helical surface of the first cylinder, the cylinders are concentric to each other and prevented from mutually-and-forth movements, with one of the cylinders is connected with a fixed part of the aerodynamic surface, and the other rotary part, the plunger is placed in the inner cylinder with the possibility of translational and rotational movements, the finger is mounted on the plunger and communicates with the helical surfaces of both cylinders through the spherical bushing, and screw the surface of each cylinder is formed with lateral surfaces of the helical grooves made on diametrically opposite sides of the cylinder shells. The grooves in the outer cylinder can be made in the form of grooves on the inner surface of the shell of the cylinder or end-to-end - all thickness of the shell, the inner cylinder is transparent, and to ensure the necessary law of sowing is a constant or variable pitch. Due to the presence of these distinctive features, allowing twice as slow coil of the transducer and the actuator, which significantly reduces the longitudinal dimension of the drive device, and double shoulder tackle loads (load is overcome in the medium diameter of the cylinder screw Converter), in conjunction with the known (specified in rancitelli part of the formula), achieved the following technical result is compared with the prototype reduced the size and weight of the rotary device, and accordingly, the weight and dimensions of the aerodynamic surfaces, provides a more effective functioning of the coil of the transducer under high aerodynamic loads and large angles of opening. The proposed solution can be used in the construction of collapsible steering surfaces of unmanned aerial vehicles. The invention is illustrated figure 1, 2, 3. 1 shows a General view of the collapsible aerodynamic surface with a spiral motion Converter, figure 2 - cross section through the screw Converter in the unfolded position of the rotating part, figure 3 - cross-section through the screw Converter in the folded position of the rotating part. We offer folding aerodynamic surface contains a fixed part 1, pivotally hung on her swivel part 2. With the rotating part 2 is connected to the cylinder 3, in which with the possibility of relative rotation is placed in the cylinder 4, which is connected with the fixed part 1. On the shells of the cylinder is screw slots 5 and 6, with the side surfaces of which (through the spherical bushing 7 and 8) interacts finger 9, fixed to the plunger 10 of the actuator 11. From mutual the CSOs longitudinal displacement of the cylinders is limited thrust bearing 12. Described folding aerodynamic surface is as follows. When triggered, the actuator 11 of the plunger 10 moves the finger 9 and the screw slots 5 and 6. Interacting with a screw slot 5, the finger 9 is rotated with the pusher 10 relative to the fixed part 1 by turning the screw through the slot 6 of the rotary part 2 at the same angle. Interacting with a spiral slot 6, the finger 9 advanced rotates the rotatable part 2. Thus, the smaller the course actuator and screw transducer provides the necessary angle folding aerodynamic surfaces, "outside the groove of the rotation limiter screw in the proposed Converter becomes "work" - it also rotates the rotary surface on its part of the angle folding. Folding aerodynamic surface, comprising a fixed and a hinged hinged on her rotary part, a plunger sliding within the holes of the hinge, and screw the Converter of the translational motion of the pusher into a rotary movement of the rotary part of the aerodynamic surface, comprising a cylinder with helical surfaces and interacting with them the finger, wherein the coil transducer comes with a second cylinder with helical surfaces other healthy lifestyles the tion, than the helical surface of the first cylinder, the cylinders are concentric to each other and prevented from mutually-and-forth movements, with one of the cylinders is connected with a fixed part of the aerodynamic surface, and the other rotary part, the plunger is placed in the inner cylinder with the possibility of translational and rotational movements, the finger is mounted on the plunger and communicates with the helical surfaces of both cylinders through the spherical bushing, and screw the surface of each cylinder is formed with lateral surfaces of the helical grooves made on diametrically opposite sides of the cylinder shells.
