Abstract

The invention relates to an extension-type orbital module comprising an inner cabin (1), a middle cabin (2) and an outer cabin (3). During the process of lifting off by a carrier rocket, the extension-type orbital module is in a fold-up state and its volume is approximately equal to the volume of the outer cabin (3). After entering the orbit, the extension-type orbital module extends outward, thus the space for astronauts to live or work is significantly enlarged. The use of multiple sealing measures ensures the safety of the astronauts inside the cabins. While constructing a space station of the same scale, launching the extension-type orbital module can reduce the number of launches, save launching costs, and save manpower as well as resources. The astronauts do not have to go out of the cabins while the extension-type orbital module is extending outwards; therefore, the operating procedure is simple, the strength is small, the time is short, no accessories are required to be taken along, and few tools are required to be carried.

5th step, docks the outer cabin on outer cabin machinery and docks machinery docking with the known propelling module on known propelling module. After completing above-mentioned installation, spaceman can be moved in interior cabin by the known hatch door on Shang Nei cabin, interior cabin docking machinery, then closes Close this hatch door.At this moment this scalable orbital module just can be launched by carrier rocket.

Scalable orbital module enter the orbit after known relevant rocket firing on propelling module, this scalable orbital module is carried out posture adjustment or boosting, The docking machinery of the interior cabin on interior cabin is made to dock machinery docking with the known space station on space station；Then it is to stretch to be somebody's turn to do In scalable orbital module is allowed to cabin, space increases, and operation sequence is divided into stretching, extension preparation, for the first time stretching, extension, second time to stretch, structure The programs such as life or working environment.

Stretch and prepare: in interior cabin, stretch unrelated spaceman with scalable orbital module, dock machinery by this Shang Nei cabin, interior cabin On hatch door transfer to space station, be then shut off this hatch door.The spaceman carrying out stretching operation in staying this interior cabin is dressed known Spacesuit.

Stretching for the first time: unscrew the valve cock nut on interior cabin, in interior cabin seals gallbladder, gas is released, the most scalable rail In cabin, road, air releases the most therewith.Again from this after the bolt and nut on this interior cabin middle deck rear thread hole from middle deck being screwed out Interior cabin bolt hole on interior cabin exits.Under the promotion of mobile device, this middle deck the most slowly slides relative to this interior cabin, When the non-threaded cylinder of the middle deck bolt on this middle deck contacts with the rear end face of location, the interior cabin straight trough on this interior cabin, will The outer end of this bolt and nut is by the interior cabin bolt hole on this interior cabin, in the middle deck preceding thread hole being then threaded on this middle deck, and will This interior cabin and this middle deck again fasten and are combined into entirety.Pump is connected with the inlet end of the valve cock on this interior cabin and passes through this gas Door mouth seals gallbladder and again squeezes into gas to this interior cabin, again this interior cabin is sealed in this middle deck after the volumetric expansion of this interior cabin sealing gallbladder In.

Second time stretches: unscrew the valve cock nut on middle deck, and in middle deck on this middle deck seals gallbladder, gas is released.By this middle deck On bolt and nut rear thread hole, outer cabin on outer cabin in screw out after again the middle deck bolt hole from this middle deck exits.Moving Under the promotion of dynamic device, the most slowly slide relative to this middle deck in this outer cabin, when the nothing of the outer cabin bolt on this outer cabin When threaded cylinder contacts with the rear end face of the middle deck location straight trough on this middle deck, by the outer end of this bolt and nut by this middle deck On middle deck bolt hole, in the preceding thread hole, outer cabin being then threaded on this outer cabin, this middle deck is fastened again with this outer cabin and is combined into Overall.Pump is connected with the inlet end of the valve cock on this middle deck and seals gallbladder by this valve cock to this middle deck squeezes into gas again Body, is sealed in this middle deck in this outer cabin again after the volumetric expansion of this middle deck sealing gallbladder.

Build life or working environment: in scalable orbital module, again inject air.

Hereafter spaceman just can be lived in scalable orbital module or work, but in it, space has expanded many.

Mobile device mentioned above is the known retro-rocket on propelling module, and after this retro-rocket is lighted a fire, the thrust of generation overcomes Frictional resistance, can make outer cabin slide backward relative to middle deck, or makes middle deck internal cabin mutually slide backward.

For extending the working life of scalable orbital module, the interior cabin on this scalable orbital module seals gallbladder, middle deck seals gallbladder badly In spatial environments, the palpus energy long period is the most aging.

For ensureing spaceman safety, having the component in the space of spaceman life or work in scalable orbital module, corner should be adopted Use fillet structure.

Scalable orbital module in stretching process in order to not damage, the size of the thrust produced after the igniting of retro-rocket on propelling module Must strictly control with the duration of ignition:

When stretching for the first time, incipient stage thrust acts on the stiction of middle deck slightly larger than interior cabin.This middle deck relative to this interior cabin to When the most slowly sliding, by the size adjustment of thrust to the force of sliding friction acting on this middle deck equal to this interior cabin.In on this middle deck When the non-threaded cylinder of cabin bolt soon contacts with the rear end face of location, the interior cabin straight trough on this interior cabin, this retro-rocket stops Only work, after this middle deck continues slip one section the most relatively because of inertia, the non-threaded cylinder of this middle deck bolt and this interior cabin When the rear end face of location straight trough contacts, this middle deck is just reduced to zero with the relative velocity in this interior cabin.

When second time stretches, incipient stage thrust acts on the stiction in outer cabin slightly larger than middle deck.This outer cabin relative to this middle deck to When the most slowly sliding, by the size adjustment of thrust to the force of sliding friction acting on this outer cabin equal to this middle deck.Outside on this outer cabin When the non-threaded cylinder of cabin bolt soon contacts with the rear end face of the middle deck location straight trough on this middle deck, this retro-rocket stops Only work, after slip one section the most relatively is continued because of inertia in this outer cabin, the non-threaded cylinder of this outer cabin bolt and this middle deck When the rear end face of location straight trough contacts, this outer cabin is just reduced to zero with the relative velocity of this middle deck.

Owing to the size of frictional force is non-constant, retro-rocket may need repeatedly to light a fire and control well the time lighted a fire, and constantly carries out Regulation.

As required, the external peripheral surface in the outer Shang Waicang stage casing, cabin of scalable orbital module can install solar panel.

In order to reduce impact force in the stretching process of scalable orbital module, following buffer structure can be used:

The cylindrical diameter of non-threaded of the middle deck bolt on reduction middle deck, then one, set has on this non-threaded cylinder Elastic soft overcoat, but on this non-threaded cylinder of holster, after this overcoat, the external diameter of this overcoat positions straight trough still equal to Shang Nei cabin, interior cabin Width.

Reduce the cylindrical diameter of non-threaded of outer cabin bolt on outer cabin, then on this non-threaded cylinder, overlap one have Elastic soft overcoat, but on this non-threaded cylinder of holster, after this overcoat, the external diameter of this overcoat positions straight trough still equal to middle deck on middle deck Width.

After using such structure, the lift-off of scalable orbital module is passed through to stretch after entering the orbit, and its dischargeable capacity significantly increases, and is available for relatively Many aerospace are within it lived or work.Build identical scale spatial station, compare single cabin and launch, launch scalable orbital module and can reduce Emitting times, saves transmitting funds, uses manpower and material resources sparingly, large number of ground scientific research personnel can be allowed to have the more time to be engaged in scientific research. This core technology can be greatly improved the transmitting benefit of rocket.

After using such structure, seal, due between middle deck and interior cabin owing to there being multiple middle deck to seal gallbladder between outer cabin and middle deck Have multiple interior cabin to seal gallbladder to seal, multi-sealed meaning multiple security.This core technology can ensure that spaceman is at scalable orbital module Interior safety.

After using such structure, spaceman need not go out cabin, just can complete the stretching, extension of scalable orbital module in scalable orbital module, Program is simple, and intensity is little, and the operating time is the longest, needs the instrument carried few.
