(57) Abstract:The invention relates to an astronaut and about creating hydrolaboratory test facilities for training astronauts for extravehicular activity in the conditions of their stay for a long time in hydro-environment. Hydroabrasive building includes pool, suspended platform with clamps and drive its ascent-descent. The pool is equipped with interacting with the platform vertical rotary columns for them in the height of the lugs and rails. The platform is suspended on power circuits. The tabs can be placed on the platform and executed in the form of spring-loaded dogs associated with the power circuit by means of flexible elements. Flexible elements retainers it is reasonable to provide brightly colored floats.

The invention relates to the field hydrolaboratory test facilities for training astronauts for extravehicular activity in the conditions of their stay within disannul platform with clamps and drive its ascent-descent (see auth. mon. N 1444629, IPC G 01 M 10/00 from 1988).Constructive execution of a known hydrolaboratories construction has the disadvantage that it though and allows you to install the platform on small plots, but do not provide the required security, because the tabs structures that interact with suspended elements, with the disengagement of at least one of them is able to hold the platform against tilting or misalignment.The proposed solution is devoid of the above disadvantages due to the fact that the pool hydrolaboratories facilities equipped with interacting with the platform vertical rotary columns for them in the height of the lugs and rails. When this locking structures are located on the platform and made in the form of spring-loaded dogs associated with the power circuit by means of flexible elements, equipped with brightly coloured floats.The technical result of the present invention is the ability to set the platform to the required levels of immersion in the hydro-environment by improving the reliability of structures.Offer hydroabrasive the construction shown in the drawings, where
in Fig. 1 shows it In FD (the dog).Hydroabrasive structure includes walling 1, pool 2, which houses the rotary columns 3, 4, 5, 6. Each column stops mounted 7, 8, 9, 10, 11, the rail 12 and drives the rotation of the columns 13, 14, 15, 16. Between the rotary columns suspended platform 17 on power circuits 18, 19, 20, 21. The power circuit pass through blocks 22, 23, 24, 25, 26, 27, 28 and 29 to the actuator (not shown). The blocks are installed on the stationary columns 30, 31, 32, 33, mounted outside of the pool 2.The platform 17 is equipped with retainers in the form of dogs 34, 35, 36, 37, turning in their housings 38 on the axis 39 under the action of springs 40. Each dog is connected by a flexible element 41 with its circuit 18 to 21. Each flexible element 41 is mounted brightly coloured float 42.Works hydroabrasive structure as follows:
In pool 2 is filled with water to the specified level. The platform 17 installed the necessary devices for power circuits 18, 19, 20, 21 is immersed to a certain level (less than specified). Then turning columns 3 to 6 are rotated 90ochocks 7 - 11 mounted under the platform 17, which is then lowered onto the blocks. During the movement of the platform 17 of the pawl 34 to 37 using a flexible element 41 is mA 17 is lifted, columns 3 to 6 are rotated in the opposite direction and free platform can move to any new level or to the initial position (up), where the operation to rotate the columns 3 to 6 are repeated.Upon release of the platform 17 stops from 7 - 11 and move it to another level, you may experience an emergency condition due to breakage of the power circuit 18 to 21 or weaken it. In this case, under the action of springs 40 of the pawl 34 to 37 are rotated in their housings 38 and occupy the position shown in Fig. 4 by the dot-dash, caplease with the rail 12, while at the breakage of the flexible element 41 floats the float 42, signaling the actuation of the pawl 34 to 37, without breakage of the power circuit.In the course of the experiments, the platform 17 is stopped at depths of 2, 4, 6, 8 and 10 meters. The need of stops due to the safety of astronauts during diving descents for training for extravehicular activity. This reduces the time the astronauts are under the greatest pressure (10 m), and also excludes the possibility of atmospheric overload when long-time work in hydro-environment.Constructive implementation of the proposed hydrolaser is a high degree of security without performing decompression in long time trials. 1.

FIELD: optimization and testing of equipment for grouped and associated launches of satellites.
SUBSTANCE: proposed method includes ground experimental optimization of turntable for action of operational loads followed by check of turning system for serviceability and flight and design tests. Ground optimization of turntable is performed together with flight model of adapter. For testing the turntable for action of operational loads on vibration table, use is made of satellite mock-up. Tests for separation of mock-up (in weightlessness state) from turntable fixed in initial position, use is made of standard satellite separation system. Then mock-up is again mounted on turntable and is subjected to test for operation of turning system together with mock-up (in weightlessness state of mock-up and turntable). Flight and design tests of turntable are performed during individual launch of satellite with the use of adapter and turntable after ground experimental optimization. Mass and moment and centering characteristics of satellite correspond to mass and moment and centering characteristics of mock-up for performing ground optimization of turntable. Turn of turntable on adapter is performed after separation of satellite from turntable secured in initial position.
EFFECT: reduction of economical expenses (by 65-70%) and optimization time.
