Description

The utility model relates to stands for ground testing of space technology, mainly to self-expanding structures such as a solar battery.

A known test bench for opening the solar battery, containing mounted on a transport ring horizontally mounted in the upper part of the spacecraft, sectional folding rods located in plan above the corresponding sections of the folding solar panels and associated with them by means of vertically mounted detachable latches and adjustable spring-free springs, Supporting pylons with horizontal shelves are fixed on the ceiling of the room, and on the sectional folding rods from the side folding folding solar panel panels, support rollers are installed with the possibility of their interaction with the open position of sectional folding rods with horizontal shelves of bearing pylons, while horizontal shelves are equipped with inclined receivers of supporting rollers, and spring-loaded permanent magnets mounted with the possibility of their interaction with the slats are fixed on bearing pylons made of magnetic material and mounted on sectional folding bars. (Patent No. 229984. IPC: B64G 7/00, G01M 13/00, G01M 17/00, B64G 5/00. Published on 05.27.2007).

The disadvantage of this device is the complexity of the design of the stand, which does not allow you to accurately simulate real conditions corresponding to the work of space technology in near-Earth space.

A known test bench for opening the solar battery, containing a truss fixedly mounted and fixed on the base, in the upper part of which is fixed a fixed beam with articulated levers that simulate the kinematic characteristics of the shutters of the test panels BS and connected to the shutters by cables, on the truss coaxially with the axis of rotation of the BS panel along the pitch, a technological frame is pivotally mounted with a balancing weight and with an inertia moment equal to the moment of inertia of the BS panel relative to its rotation axis, A BS panel is fixed at regular seats and interacts with a two-link articulated strut, the second link of which is pivotally mounted on the technological frame, which is equipped with a spring interacting with the strut hinge, while the BS panel and the technological frame are movably fixed on one shaft, which also interacts by means of a cam covering the shaft with a spring compensator rigidly fixed to the base, and the cables connecting the articulated levers to the BS flaps are equipped with dampers, moreover the cables have a length of not more than 0.5 m, and the stiffness of the spring compensators is calculated using the formula. (Patent No. 2468969. IPC: B64G 7/00. Publ. 10.12.2012).

The disadvantage of this device is the complexity of the design of the stand, which does not allow you to accurately simulate real conditions corresponding to the work of space technology in near-Earth space.

A known disclosure stand of the solar battery containing a support mounted and fixed on the base, in the upper part of which is mounted a weighing device in the form of separate links articulated between each other and located above the corresponding flaps of the solar battery, and the axis of rotation of each link of the weighing device coincides with the axis of rotation the corresponding flap of the solar battery, and damping devices, damping devices are installed in each link of the weighing device and in the middle pendants are rigidly connected to the shutters of the solar battery, while the platform is rigidly fixed to the support, in which similar seats are made above and below for simulating the spacecraft to provide alternate opening of the mirrored shutters of the solar battery, and guides for the bracket are made in the upper part of the support with the possibility of its movement in the horizontal direction, which, in turn, interacts rigidly with the first link of the weighting device, and the support itself is fixed and on the basis of the adjustable racks, providing the exposure of the solar panel panels in a vertical position, and between the links of the weighing device and the shutters of the solar panel there is a gap of not more than 150 mm. (Patent No. 2483991. IPC: B64G 7/00, B64G 1/44. Published. 06/10/2013).

The disadvantage of this device is the complexity of the design of the stand, which does not allow you to accurately simulate real conditions corresponding to the work of space technology in near-Earth space.

As the closest analogue (prototype), the astronaut’s weightlessness simulation stand was chosen consisting of a control unit, a respiratory mixture supply station, an energy supply unit and a metal structure with trolleys moving in a horizontal plane having horizontal movement mechanisms, the metal structure is mounted on fixed supports, on one of the supports placed a vertical movement mechanism, a spacesuit, through a vertical load sensor, connected to a vertical movement mechanism, and sensors g Horizontal loads are mounted on trolleys moving in a horizontal plane. (Patent No. 152039. IPC: B64G 7/00. Published. 04/27/2015).

The disadvantage of this device is its limited functionality.

The technical problem solved by the utility model is to increase the accuracy of simulating conditions in near-Earth space when the solar battery is opened.

The problem is solved due to the fact that the test bench of the solar battery contains a control unit 1, a metal structure 2 with trolleys 3 moving in a horizontal plane, which is mounted on stationary supports 4, aerostatic supports 5 and compressor 6, with aerostatic supports 5 placed on trolleys 3 and connected to the compressor by hoses 7.

The technical result is the deprivation of the panels of the solar battery, when it is opened, during the horizontal movement of the solar cells due to the use of trolleys with aerostatic supports.

In FIG. 1 shows a stand for testing a solar battery (side view).

In FIG. 2 shows a test bench for a solar battery (top view).

The test bench of the solar battery works as follows. Before starting the test, the solar panel is suspended from the bogies 3. The operator from the control panel 1 turns on the compressor 6, compressed air through hoses 7 enters the aerostatic supports 5 mounted on the bogies 3. A thin air film is created between the aerostatic supports 5 and the metal structure 2. Carts 3 float above the surface of the metal structure 2, weightless solar panels. The operator, from the control unit 1, activates a squib (not shown in FIG.) Mounted on the assembled solar battery, which, when activated, releases the lock (not shown in FIG.) Holding the solar panel assembly. Under the action of elastic elements (not shown in FIG.) Built into the design of the solar battery, it begins to unfold. The solar panel panels are moved horizontally, supported by bogies 3 on aerostatic supports 5, with a minimum value of the coefficient of friction-slip.

Claims (1)
