Description

A useful iodel belongs to the field of aircraft, namely, to the structural elements of the wing folding wings.

A known mechanism for opening the wing (see media patent No. 3853288, cl. 244.3.29, 19741, in which the mechanical drive is made in the form of a torsion spring from a wire of circular cross section, marked at the critical section of the nozzle of the engine. A rigid ring with longitudinal grooves is an open element). in which, in the folded position, the rotary parts of the wings enter.The ring, turning under the action of the central spring, squeezes the rotary parts of the wings and puts them into working position. and torsion, lawsuit | 11; | det - the possibility of increasing the spring force due to limitations, according to the required disclosure, change the hard ring and the diameter of the spring wires on one side and the weight of the spring on the other. A couple of the rigid ring opening part creates a significant friction moment, prevention of disclosure.

A known mechanism for the disclosure of the wing (see patent SIA No. 2784 & B9, cl. 244.3.29, 1954), in which the mechanical drive is made in the form of a torsion spring from a wire of rectangular cross section, marked at the critical section of the nozzle of the engine. The disclosed element is the central driving wheel. One End Spring

mounted on the rocket body, its other end engages with the wheel of the Veductia. The central non-gear wheel engages with wheels fixed on the rotation axes of the rotary parts. This design has an increased mass of the mechanical drive and significant friction between the opening elements, and the presence of cores on the wing axis worsens the rocket's aerodynamics.

A known mechanism for opening the wing (see patent C1 No. 4296895, class 244.3.29, 1981) TAKEN As a prototype, in which the mechanical drive is made in the form of a torsion spring marked along the axis of rotation, the wing part opens. One end of which is fixed on the fixed part of the wing, the other - on the open part. As a help for opening the element, a cable is used, with the help of which the opening parts of the wings are connected. The design of the wing opening mechanism is a unified system, allowing to summarize the forces from the springs of each wing. Intermediate cable supports are installed on the body in the form of supporting rollers, increasing the aerodynamic drag of the rocket. The flexible cable eliminates the possibility of using the helping disclosure of the aerodynamic force and inertia of the rotary parts, which reduces the efficiency of the system.

The technical result that this useful provides

the model swears that the use as a mechanical drive of tension springs connected in a unifying system

wing openings, distributed in the missile body, allows to obtain significant disclosures of nonents, with no weight and azrodynamic resistance of the mechanism’s elements.

The technical result is achieved by the fact that the disclosure mechanism comprises, as a connecting element, a central ring with vernally fixed rods, the other end of which is connected with the rotary part of the wings. A mechanical drive in the form of tensile springs mounted on the body is connected via traction to the rotary parts of the wings. That allows, through the central ring, to combine the efforts of the springs in a single opening moment on the shoulder from the center of the rocket to the axis of the springs. An increase in useful moment is achieved by using the design of the mechanism for disclosing the principle of summing the forces of individual springs and azrodynamic forces through a connecting element - the central ring. The use of rigid rods in the design allows, by incorporating into the work, helping to uncover the azrodynamic forces, to reduce the total counteracting moment from the wind load. The hinged connection of rigid rods with the central ring and the rotary parts of the wings, allows you to use their own moments of inertia in the disclosure.

The utility model is illustrated by drawings, where in FIG. Figure 1 shows the location of the opening mechanism on the tip of a rocket fragment with wings spread. In FIG. 2 shows the transverse

section of the rocket along the element and non-disclosure of opening with folded wings, and in FIG. 3 in the working position of the wings.

The wing opening mechanism includes a central ring 1, thrust 2, tension springs 3, a rotatable part of the wing 4, a rocket body 5, a rocket engine nozzle b.

The central ring 1 has a support surface on the nozzle of the engine 6. The rods 2 are connected to the ring i and the rotary parts 4. They are connected to the rods by tension springs 3, the other end of which is attached to the housing 5.

The mechanism works as follows. The rotary part 4 opens from the folded position to a position that is a continuation of the root part, and is called the worker, under the action of the forces of the springs 3, creating through the rods 2 and ring 1 at a distance from the axes of the springs to the center of the rocket the total opening moment.
