Known related rocket firing after scalable orbital module is entered the orbit on propelling module, posture adjustment is carried out to the scalable orbital module Or boosting, the inside cabin in inside cabin is docked mechanical device and mechanical device docking is docked with the known space station on space station；Then To stretch the scalable orbital module and be allowed in cabin space to increase, operation sequence be divided into stretching, extension prepare, stretching, extension for the first time, second The programs such as stretching, extension, structure life or working environment.
Stretching, extension prepares：The astronaut unrelated with the stretching, extension of scalable orbital module, passes through inside cabin docking machine in the inside cabin in inside cabin Hatch door on tool device is transferred to space station, is then shut off the hatch door.The astronaut for stretch operation is stayed in the inside cabin to wear Wear known suit.
Stretch for the first time：The valve cock nut in inside cabin is unscrewed, inside cabin is sealed into gas in courage releases, and at the same time can stretch Air also releases therewith in contracting orbital module.After bolt and nut in the inside cabin is screwed out from the middle deck rear thread hole on middle deck Exited again from the inside cabin bolt hole in the inside cabin.Under the promotion of mobile device, the middle deck is with respect to the inside cabin axially rearward Slowly slide, when the rear end of the non-threaded cylinder and the inside cabin positioning straight trough in the inside cabin of the middle deck bolt on the middle deck When face contacts, by the outer end of the bolt and nut by the inside cabin bolt hole in the inside cabin, the middle deck being then threaded on the middle deck In preceding thread hole, the inside cabin and the middle deck are fastened again and are combined into entirety.The air inlet of pump and the valve cock in the inside cabin End connection simultaneously squeezes into gas again by the valve cock to inside cabin sealing courage, again should after the volumetric expansion of inside cabin sealing courage Inside cabin is sealed in the middle deck.
Second of stretching, extension：The valve cock nut on middle deck is unscrewed, by gas is released in middle deck sealing courage on the middle deck.Should Bolt and nut on middle deck moves back from the middle deck bolt hole on the middle deck again after being screwed out from the outer cabin rear thread hole on outer cabin Go out.Under the promotion of mobile device, the outer cabin is slowly slided axially rearward with respect to the middle deck, when the outer cabin positioning on the outer cabin When the non-threaded cylinder of bolt contacts with the rear end face of the middle deck positioning straight trough on the middle deck, by the outer end of the bolt and nut By the middle deck bolt hole on the middle deck, it is then threaded into the outer cabin preceding thread hole on the outer cabin, by the middle deck and the outer cabin weight New fasten is combined into entirety.Pump is connected and close to the middle deck by the valve cock with the inlet end of the valve cock on the middle deck Envelope courage squeezes into gas again, and the middle deck is sealed in the outer cabin again after the volumetric expansion of middle deck sealing courage.
Structure life or working environment：Again air is injected into scalable orbital module.
Hereafter astronaut can live or work in scalable orbital module, but its interior space has expanded many.
Mobile device described above is the known retro-rocket on propelling module, caused to push away after the retro-rocket is lighted a fire Power overcomes frictional resistance, outer cabin can be made to be slided backward with respect to middle deck, or middle deck is slided backward with respect to inside cabin.
To extend the working life of scalable orbital module, inside cabin sealing courage, middle deck sealing courage on the scalable orbital module Must energy long period not aging in severe space environment.
To ensure astronaut's safety, there are the component in the space of astronaut's life or work, corner in scalable orbital module Place should use fillet structure.
Scalable orbital module in stretching process in order to not damage, caused thrust after the igniting of retro-rocket on propelling module Size and the duration of ignition must strictly control：
When stretching for the first time, incipient stage thrust acts on the stiction of middle deck slightly larger than inside cabin.The middle deck is relative should When inside cabin is slowly slided backward, by the big minor adjustment of thrust to the force of sliding friction that the middle deck is acted on equal to the inside cabin.In this , should when the non-threaded cylinder of middle deck bolt on cabin soon contacts with the rear end face of the inside cabin positioning straight trough in the inside cabin Retro-rocket is stopped, after the middle deck continues relative one section of slip backward because of inertia, the non-threaded circle of the middle deck bolt When cylinder contacts with the rear end face of inside cabin positioning straight trough, the middle deck and the relative velocity of the inside cabin are just reduced to zero.
During second of stretching, extension, incipient stage thrust acts on the stiction in outer cabin slightly larger than middle deck.The outer cabin is relative should When middle deck slowly slides backward, by the big minor adjustment of thrust to the force of sliding friction that the outer cabin is acted on equal to the middle deck.This is outer , should when the non-threaded cylinder of outer cabin bolt on cabin soon contacts with the rear end face of the middle deck positioning straight trough on the middle deck Retro-rocket is stopped, after relative one section of slip backward is continued in the outer cabin because of inertia, the non-threaded circle of the outer cabin bolt When cylinder contacts with the rear end face of middle deck positioning straight trough, the outer cabin and the relative velocity of the middle deck are just reduced to zero.
Because the size of frictional force is non-constant, retro-rocket may need repeatedly to light a fire and control the time of igniting, no It is disconnected to be adjusted.
As needed, solar panel can be installed on the external peripheral surface in the outer cabin Shang Waicang stage casings of scalable orbital module.
In order to reduce impact force in the stretching process of scalable orbital module, following buffer structure can be used：
Reduce the diameter of the non-threaded cylinder of the middle deck bolt on middle deck, then one is covered on the non-threaded cylinder Individual flexible soft overcoat, but on the non-threaded cylinder of holster after the overcoat external diameter of the overcoat still equal to inside cabin in inside cabin Position the width of straight trough.
Reduce the diameter of the non-threaded cylinder of the outer cabin bolt on outer cabin, then one is covered on the non-threaded cylinder Individual flexible soft overcoat, but on the non-threaded cylinder of holster after the overcoat external diameter of the overcoat still equal to middle deck on middle deck Position the width of straight trough.
After such structure, scalable orbital module lift-off is significantly increased after entering the orbit by stretching, extension, its dischargeable capacity, can Life or work in it for more aerospace.Identical scale spatial station is built, compares single cabin transmitting, launching scalable orbital module can Emitting times are reduced, transmitting funds is saved, 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 Work.The core technology can greatly improve the transmitting benefit of rocket.
After such structure, due to there is the sealing courages sealing of multiple middle decks between outer cabin and middle deck, due to middle deck with it is interior There are multiple inside cabin sealing courage sealings, multi-sealed meaning multiple security between cabin.The core technology can ensure that astronaut can stretch Safety in contracting orbital module.
After such structure, astronaut need not go out cabin, and just scalable orbital module can be completed in scalable orbital module Stretching, extension, program is simple, and intensity is little, and the operating time is not long, it is necessary to which the instrument carried is few.
