RU2726300C1 - Boot fixing device to provide spaceman escape from suit - Google Patents

Abstract

FIELD: space equipment.SUBSTANCE: invention relates to space engineering, particularly, to spacecraft astronaut output from space suit. Device for fixing shoes to provide for spaceman's escape from the space suit includes a support platform, a bent staple, space suit shoe locks fixators located on the outer surface of the support platform. It includes L-shape suit boots socks fixing devices arranged opposite to boot track retainers at the distance of space suit boot length. Distance between said retainers is not less than the width of the space-order boot. Curved bracket intended for provision of the space suit outer jacket fixing in the shin area is made as C-shaped with cutout width not less than the width of the space suit and is installed on the support platform by means of brackets attached to the bracket at points of its maximum curvature.EFFECT: higher reliability of fixation.1 cl, 4 dwg

Description

The invention relates to space technology, in particular to equipment for ensuring work in space conditions, namely, to devices used in the preparation and conduct of work on extravehicular activities, intended for the release of an astronaut from a spacesuit.

A device for fixing the boots of the "Anchor" spacesuit is known, where elements of fastening on the boots and the pressurization characteristic of the spacesuit are used. The device contains a support platform, a spatial curved bracket for attaching the toe of the boots and stops for the heel area of the boots. (Tsygankov O.S., Fifty years of extravehicular activity. "Space technology and technology." No. 1 (8), 2015, p. 10, fig. 10).

The disadvantage of this device is the need to pressurize the boot of the spacesuit for fixation. When performing the operation to exit the spacesuit, the astronaut equalizes the working pressure in the spacesuit with atmospheric pressure, which leads to the absence of boot inflation, and, as a consequence, to unreliable fixation.

The objective of the invention is to provide an ergonomic, reliable and safe boot fixing device for ensuring the exit of the astronaut from the spacesuit, which ensures the boot of the spacesuit is fixed in a non-inflated state.

The technical result consists in the possibility of operating an ergonomic, reliable and safe boot fixing device intended for the astronaut to exit the spacesuit and ensuring the fixation of the spacesuit boots in an unaddressed state.

The technical result is achieved by the fact that in the boot fixation device to ensure the exit of the astronaut from the spacesuit, containing a support platform, a curved bracket, spacesuit boot spur retainers located on the outer surface of the support platform, spacesuit boot sock locks are introduced, made L-shaped and located opposite boot spur locks at the distance of the spacesuit boot length, and the distance between the mentioned locks should be no less than the spacesuit boot width, while the curved bracket is designed to secure the outer shell of the spacesuit in the shin area, made C-shaped with a cutout width not less than the spacesuit boot width and is installed on the support platform using brackets attached to the bracket at the points of its maximum curvature.

The essence of the invention is illustrated by drawings (Fig. 1-4).

In FIG. 1 - device from the side of the spacesuit boot sock locks.

In FIG. 2 - device from the side of the spacesuit boot spur retainers.

In FIG. 3 - placement of an astronaut in a spacesuit when using the device inside the airlock module.

In FIG. 4 - an experimental sample of the device.

The following designations are adopted in the figures:

1 - support platform;

2 - boot spur clamps;

3 - locks of toes of shoes;

4 - curved bracket;

5 - brackets;

6 - gateway module.

The proposed device for fixing boots to ensure the exit of the astronaut from the spacesuit contains a support platform 1, a curved bracket 4, clips of the spurs of the boots of the spacesuit 2 located on the outer surface of the support site 1, clips of the toes of the boots of the spacesuit 3, made L-shaped and located opposite the clips of the spurs of the boots 2 at the distance of the length of the spacesuit boot, and the distance between the mentioned locks 2 and 3 must be not less than the width of the spacesuit boot. The curved bracket 4 is designed to secure the outer shell of the spacesuit in the lower leg area, is made in a C-shape with a cutout width not less than the width of the spacesuit boot and is installed on the support platform 1 using brackets 5 attached to the bracket 4 at points of its maximum curvature (Fig. 1-2).

The proposed device is located and secured inside the airlock module 6 before carrying out extravehicular activities (Fig. 3-4).

The proposed device is operated by an astronaut after the reverse sluicing process as follows. The cosmonaut places the boot of the spacesuit in the bent bracket 4, resting the sole of the boot on the support platform 1, resting the spur of the boot against the spur retainer 2, and then by turning the boot fixes its toe in the toe of the boot of the spacesuit 3. The cosmonaut performs similar operations with another boot.

The proposed device can be made of the following materials:

- support platform, boot spur lock and boot toe lock - aluminum alloy AMg6 GOST 17232-99;

- bent bracket - pipe AMg6.M. KR OST 192096-83.
