Description

The invention relates to experimental space orbital vehicles and planetary bases.

The operating experience of the Salyut, Mir, Skylab, ISS orbital stations showed a huge shortage of the required volumes of pressurized compartments of space complexes required for storing raw materials, materials, spare parts, food, water and consumables in orbit to ensure the life of crews, experiments, space production, providing microgravity, placing a greenhouse for food production [1].

History of the issue

Since the 60s of the 20th century, inflatable pressurized compartments have been considered as one of the available technical solutions for increasing the volume of pressurized compartments. In the United States, the life cycle of the creation of an NGO went through the stages of theoretical studies [1], preliminary design, detailed design of demonstrators for ground tests and prototypes for flight tests [1, 2].

The patents and rights to work on the program were bought up by the private company Bigelow Aerospace to be used as the base for its Nautilus orbital hotel project. The Bigelow Aerospace project provided for the launch of a working module into orbit by 2015 [1, 2].

To test the technology, Bigelow Aerospace launched the first Genesis I module into an orbit with an altitude of 500 km on July 12, 2006 [2]. The launch was carried out using a Dnepr carrier rocket from the Dombarovskiy positioning area (Orenburg region). Module weight - 1400 kg, length - about 4 meters, diameter - 1.9 meters. After insertion into orbit, the diameter of the module should have doubled. Later on the same day, the company confirmed that the launch went off without comment and after entering orbit, the module successfully deployed.

In the USA, a project was proposed for an interplanetary spacecraft with an inflatable compartment and artificial gravity - the Nautilus-X Orbital Station [2].

In Russia, the NPO named after S.A. Lavochkin developed an inflatable braking device (NTU) of the descent vehicle, which is a closed sealed shell or a series of shells forming a given shape after filling them with gas [4]. This shell docks with the object intended for descent into the atmosphere (payload). During launches, the NTU is located under the LV fairing in a folded position in a compact volume, and in space, immediately before the phase of aerodynamic braking, it is brought into a deployed operating position. NTU is designed for short-term extreme operation in conditions of high temperatures and loads.

In addition to the Genesis module, taken as a prototype, Bigelow Aerospace has designed the Guardian modules - this is a prototype of the hotel module, already made in a 1: 2 scale. Unlike Genesis, it included not only the outer hull and deployment system, but also the onboard power system, as well as the life support system [3].

Comparative characteristics of known inflatable compartments are given in table. 1.

The disadvantages of inflatable structures, limiting the scope of their application, include the lower rigidity of the shell, which does not allow the installation of precision astro-equipment and highly directional antennas on it, and also complicates the dynamics of the movement of such objects in space, which requires a combination of an inflatable structure with a frame and all-metal elements, which is proposed by the author.

In addition, new materials created for inflatable space structures are very expensive due to the small volume of production, the technologies for working with them have not been developed, which leads to the heterogeneity of the properties that require increasing the safety factors, which reduces the economic efficiency of their use.

The aim of the proposal is to propose a design that allows for its multipurpose use.

Since the deployment of orbital pressurized compartments can be carried out by compressible gas, incompressible liquid and mechanisms, it is therefore more correct to call such structures transformable.

The author proposes several options for using transformable space compartments and provides a qualitative and economic assessment of the advantages of multipurpose transformable pressurized compartments (MTGO).

At the initial stage, it is proposed to use fairly widely used materials used in body armor, airships, spacesuits and equipment for rescue, radiological and degassing services.

On the basis of the author's inventions and with the help of the proposed technology and design, a transformer module can be created for placement in the Earth's orbit as part of orbital stations, on the Moon orbit and Mars orbit, as well as as planetary modules on neighboring planets as part of planetary bases, in caves and on the surfaces of neighboring planets and other celestial bodies to house the gene pool of terrestrial life species.

The author considers the following options for using transformable hermetic structures:

- warehouse space;

- modules for waste disposal;

- gym;

- dining room;

- greenhouse;

- cover for planetary bases;

- shelter for planetary or orbital storage facilities from outer space factors;

- shelter for the industrial zone on the planetary base;

- expansion of the available habitable space of orbital stations;

- reserve rooms to ensure the internal rearrangement of the orbital station or expeditionary complex in flight;

- a conference room as part of an orbital vehicle or a planetary base;

- a film studio as part of an orbital vehicle or on a planetary base for shooting educational and feature films in space and about space;

- assembly and testing complex for assembling expeditionary complexes in orbit [8-11, 15].

Let us consider the features of the listed options for the use of MTGO and identify signs that have novelty, which together can be used in all options.

MTGO-industrial waste warehouse, is the simplest version of a transformable containment, to which the mildest requirements are imposed. In principle, it can be leaky, not have a frame and serve for storing packages and boxes with used and out-of-order equipment and garbage for burial in the ocean. Fastening of goods in the MTGO-warehouse can be carried out in standard honeycomb cells equipped with lacing to fix the goods. The MTGO warehouse can be attached to the OS in the traditional way to one of the free ports or using manipulators. After filling the warehouse with waste, it is docked with a cargo ship of the Soyuz, Progress, Clipper, Dregon and others type sailing away from the OS to impart a braking impulse to its disposal in the ocean. Considering that the cost of renting free volumes at the orbital station is about a million dollars per year per cubic meter, the income from the placement of an MTGO with a volume of 150 cubic meters. m. on the ISS can be $ 150 million per year, which ensures the payback of the storage module for one year of operation.

MTGO-gym is a damping structure to reduce the load on the OS during training and dynamic movements of astronauts inside the station. The medical requirements for the gym are quite high, corresponding to a manned space object with enhanced ventilation and vibration damping from cyclic locally applied forces. The gym is equipped with exercise bikes, a treadmill, sets of training suits such as "Chibis", etc., placed in honeycomb bags on the inner surface of the shell and on the central frame. On the central frame there is also a simulator of the "Paired squirrel wheel" type to provide cosmonauts with microgravity in the mode of paired oncoming running along the tracks of "squirrel wheels". The hall is equipped with the necessary diagnostic medical equipment for monitoring the physical condition of the crew, physiotherapy equipment for taking "oxygen cocktails" and other procedures, in particular, massagers, as well as sports equipment such as badminton, ball, etc. If there are fragile structures, they can be fenced nets, which can also serve as protection against injury.

The MTGO dining room can be combined with a greenhouse and include sections for growing edible crops in artificial soil and in aquariums. The food intake sections house refrigerators, microwave ovens, tables, armchairs and fixing devices and devices for eating in zero gravity. Here, squirrel-wheel centrifuges can also be used for eating in microgravity conditions, both with a muscular drive and with an electric drive of wheels placed along the cylindrical contour of the MTGO shell. Considering that the cost of delivering cargo to orbit is about $ 15,000 per kilogram, growing just one kilogram of food per day saves $ 5,475,000 per year for this cost item, which provides a payback period for the canteen-greenhouse module in about five years.

Shelters on planetary bases, by analogy with the roofs of sports facilities and exhibition halls on Earth, can be combined truss-film structures, using special mirror, electrostatic and other coatings on the films. If necessary (in combination), they can serve as concentrators of solar and other energy, concentrators of weak radio signals, and so on. The advantage of multilayer hollow structures is the possibility of filling them with materials extracted on the studied (developed) host planet, the possibility of increasing the mass of the filler to increase radiation and micrometeoroid protection as the required local materials are extracted and processed [11].

The shelters of the industrial zone on the planetary base are specialized shelters as part of the planetary bases and provide more comfortable working conditions for astronauts, providing diffused lighting, protection from space dust and a gentle thermal regime, an increase in the service life of spacesuits, a feeling of greater safety and comfort for personnel to increase productivity labor on the planet being mastered.

Expansion of the available habitable space of the orbital stations, reserve rooms to ensure the internal re-arrangement of the orbital station or the expeditionary complex in flight, as well as specialized rooms are used for staged work on the re-arrangement of orbital means (according to the principle of playing "tag") in the process of their deployment, so Naturally, the first modules will have a multifunctional, multipurpose purpose, gradually transforming into target ones: scientific, technological, medical modules, with the appropriate target equipment, placed in unified cells of the orbital vehicle frame.

In the future, it is possible to create conference rooms, film studios for orbital or on-planet placement, differing in large diameters (8 meters or more), to accommodate guests of the orbital vehicle, tourists, clients and patients of space sanatoriums, workers of space clinics, realizing superoperations in zero gravity, filmmakers and space correspondents.

Space hangars and assembly test orbital space complexes designed for the assembly and testing of Martian and other expeditionary complexes of a multi-module type or using nuclear engines, the inclusion of which is prohibited on Earth, stand somewhat apart. Since the expeditionary complexes have a mass of more than 500 tons, it is proposed to build hangars according to the frame-panel principle. The frames are supplied with unified fasteners for placing the shell flaps, with the possibility of closing and opening them if necessary. Inside and outside the frame, there are support locks and numerous manipulators for gripping and moving loads and assembly units. The assembly of the expeditionary complex will apparently be carried out along the longitudinal axis of the hangar, with constant control of the geometric parameters of the assembled object. The hangar shell provides comfortable conditions for installation work, soft thermal cycling, lighting, protection from micrometeoroids and radiation.

Transformable space screens can also be used to create protective structures on planetary surfaces and in outer space.

On-planet screens can provide:

- an increase in the radiation protection of the planetary equipment and the crew during work in open space;

- increasing the micrometeoroid protection of the planetary equipment and the crew.

Transformable screens [10] in open space can serve as additional OS “umbrellas” and, being combined into large-sized structures, can form space DOKs (space MICs) for assembly and testing and preparation for departure of expeditionary complexes up to the formation of a “Dyson sphere”. The concept of the Reaction Engine Ltd. campaign can serve as an analogue of such structures and hangars.

To test and clarify the composition of the MTGO package, it is necessary to create prototype demonstrators of a multipurpose transformable orbital module (MTOM - a variant of the name of the invention).

The multipurpose transformable pressurized compartment (MTGO) includes a multilayer hull, tanks for water and fuel, interconnected propulsion system and a pneumohydraulic fuel supply system, solar panels, a pressurized compartment containing a life support system, a multipurpose payload compartment and a service compartment, while multi-layer the body of the MTGO is made with the possibility of transformation, from the petals of radiation protection, meteoroid protection. In addition, to ensure deployment inside planetary embankments and caves, the radiation protection petals of the hull can be equipped with multilayer elastic chambers with the ability to fill them with water. In addition, in order to increase the protection against space debris, in the MTGO the meteoroid protection petals can be made in the form of a layered package of metal and polymer grids, while the petals located along the stabilization planes are equipped with solenoids for stabilization in the geomagnetic field, and the axial solenoid increased power for electrodynamic change of the orbit and collection of ferromagnetic debris and orbital particles for the accumulation of the mass of the MTGO in orbit for its subsequent use as a fulcrum of the tether transport system.

The MTGO or MTOM device is illustrated by drawings on 5 sheets, in the amount of 11 figures, which show the MTGO figures in the folded and unfolded state and the results of calculations of its effectiveness (the names of the figures are given in brackets).

MTGO 1 in the process of launching under fairing 2 of the "Angara-A1" LV 3 is shown in Fig. 1 (MTGO folded under the head fairing on the "Angara A1" launch vehicle) and Fig. 3 (General view of the prototype MTGO under the fairing in the transport position).

MTGO integrated with a reusable single-stage launch vehicle (MORN) of the Korona type 4 is shown in Fig. 2 when folded, and in fig. 4 (Section of the MTGO at the launch site) shows a cross-section of the folded MTGO.

The external view of the deployed experimental MTGO in orbital flight is shown in Fig. 5 (External view of the deployed MTGO in an autonomous orbital flight), and in a section during experiments with experimental equipment, in Fig. 6 (sectional MTGO deployed in orbital flight).

In fig. 7 (Variant of the multilayer MTGO shell), a section (section) of the multilayer MTGO shell is shown, and in Fig. 8 (View of the unit cell of the petal in the foamed state) Typical view of the cell 5 of the petal 6 MTGO.

In fig. 9 (The limits of applicability of the MTGO based on the volumes available under the fairings of the unified series of the "Angara" launch vehicle), a diagram of the area of application of the MTGO is shown, and Fig. 10 (Volumetric efficiency of the MTGO application) diagram of the comparative volumetric efficiency of conventional modules of the Salyut, FGB and MTGO type.

In fig. 11 (Cost-effectiveness of MHTS in comparison with traditional modules of orbital stations) shows a diagram of the cost-effectiveness of MHT in comparison with standard rigid modules.

To solve multipurpose tasks and research works, the MTGO in the folded state can be launched into orbit as integrated with the MORN of the "Korona" type (it does not require a fairing on both disposable launch vehicles), and on the launch vehicles of the "Angara", "Proton" or "Soyuz" type ".

The outer shell 8 of the MTGO body is made transformable from foldable multilayer petals-manipulators 6, ensuring reusability. In the case of the MORN "Corona", the MTHO can be deployed in flight in orbit or after landing on the planet under study, inside the MORN tanks, turning it into a space or planetary base 7.

A transformable pressurized compartment for reusable use, includes a power case 9, which houses the target 10 and service equipment 11, tanks for water 12 and fuel 13, a propulsion system 14, a pneumohydraulic fuel supply system 15. Interconnected, a power plant 16 containing a solar power plant (SPP ) 17, a multipurpose payload compartment 18 and a service compartment 19, combined into a removable space platform 20.

The proposed design of the MTGO (a prototype demonstrator of the launch vehicle of the "Angara" or MORN "Korona" type) assumes functioning in orbit and testing of all the main MTGO systems.

Ways to deploy MTGO

Considering the options for multi-layer MHTO shells cured by heat treatment in flight, it should be noted that the forming layer must be thermally insulated from vacuum, Fig. 7.

Since the MTGO can be composed of various elements, a variant of the elementary cells is proposed, from which the shape of the MTGO can be made and which, when folded, occupy a small volume.

When the final structure of the MTGO module is formed, they are pre-pressurized, then, if necessary, the state of the material in them changes (curing, foaming). These elementary forms are used in the composition of the MTGO shell.

The MTGO casing cell is a hollow multilayer element, inside of which there is a material 22 that changes its properties under technological influence and is additionally sewn / glued with inserts to maintain its shape during the pre-pressurization process.

Forming method 1: After technological pressurization, heating is proposed by various heat-heating elements (TEN) 23, in particular by microwave action, located inside the module. The shell materials are activated by heat, the thermal insulation 24 retains heat inside the cells, the foam powder 25 (fixed between 2 polyethylene films in the form of portions) absorbs heat, melts (temperature 80 ° C), and foams with a further increase in temperature. With further exposure at an elevated temperature (for example, up to 150 ° C), the final curing of the expanded foam occurs and its mechanical characteristics increase. Glass fabric 26 allows volatile gases formed during foaming to pass through.

As a source of heat 23, heating elements in the form of electric sheets 29 of the Brest plant of electrical appliances or purging the module with hot pressurization gases from fuel tanks can be used.

A full cycle (time from the activation of materials to a set of final mechanical characteristics due to exposure at elevated temperatures) can leave from 5-6 hours to a day;

Cons: Using foaming and microgravity curing materials:

- variability (the process under terrestrial conditions has not yet learned to calculate mathematically, but under microgravity conditions it becomes more complicated);

- irreversibility of the process, does not allow reverse folding of the transformer.

The section view of the shell is shown in Fig. 7. In the curable shell, the use of materials given in table is applicable. 2.

Forming method 2 - ordinary pressurization of the shell with pressurized gases of the oxygen tank (oxygen + helium) after the upper stage of the LV or MORN of the "Corona" type is injected into orbit. The reverse folding of the MTOM is carried out according to the principle of an automatic umbrella. Non-planetary MTGOs are supplied on their surface with pocket-bags for filling with local soil to increase radiation and meteoroid protection. Applicable in this method, materials MTGO are given in table. 3.

For MTGO as a MTOM, Figures 5 and 6 show the elements that ensure the autonomous operation (operation) of the module, for example, as a demonstrator: upper technological hatch 32, which can be equipped with a docking unit, upper conical skirt 33, interior panels 34, load-bearing frame 35 , shell pressurization system 36, command and measurement system with telemetry control system 37, transceiver 38, lower technological hatch 39, equipped with a docking unit, lower conical skirt 40, triaxial orientation and stabilization solenoid 41, which can be built into the petals or on power frame of the module, as well as an axial solenoid 42 of increased power for electrodynamic change of the MTOM orbit and accumulation of the orbital ferromagnetic mass on the module.

Diagrams 9-11 show the following comparative characteristics of standard modules and MTOM: available useful volume of 43 standard modules, possible volume of 44 convertible modules, volume of 45 payload zones under the LV fairing, launch price of LV 46, price of classic module 47, commercial price of an annual lease the volume of the module per year 48, the price of the transformable module 49 and the rise in the cost of the 50 transformer in relation to the standard module, the rental price of the MTGO 51.

Evaluation of the effectiveness of the use of transformable structures in comparison with traditional structures.

Depending on the applications of transformable structures, they have the advantages and disadvantages listed above in comparison with traditional OS. Consider several options for using inflatable space compartments and give a qualitative and economic assessment of the advantages of inflatable structures.

The use of transformable structures has the following advantages in the development of structures for orbital and non-planetary stations [5-7]:

- a smaller volume of cargo during launching into orbit in comparison with "rigid" modules and, as a consequence, the use of carriers of a lighter class for launching modules of the required dimensions;

- obtaining orbital modules of larger dimensions and volume than "hard" modules;

- ease of deployment;

- inflatable modules can provide a higher level of protection against adverse space factors;

- low cost in production (after mastering technologies).

So, for example, on the "Angara A5" launch vehicle at the same launch cost, both a standard FGB-type module with a diameter of 4 meters and a volume of about 120 cubic meters, and an MTGO with a diameter of 8 meters and a volume of 470 cubic meters can be launched. meters. Additional income from leasing additional volumes can be more than $ 300 million per year, which ensures payback of MTGO in one year.

The efficiency of large-sized structures - transformers can be increased by placing film solar cells (SB) on their surface. On a typical module with a diameter of 8 meters, displayed on the "Proton-M" or "Angara-A5" LV, it is possible to freely place an SB with an area of 200 sq. meters. With an effective area of 80 sq. meters SB can provide an average of 8 kW. electrical power. Considering that the cost of electricity resources on board the ISS is $ 2,000 per kW / hour, we can receive income from renting free energy sources in the amount of $ 140 million per year, which pays for the module in one year.

Let us consider the effectiveness of the MTGO shown in Fig. 4 in relation to the capabilities provided by the unified series of "Angara" type launch vehicles shown in Table. 2. It can be seen that one MTGO in terms of volume replaces up to 4 standard modules, which, despite the relative high cost of the transformer, reduces the cost of creating the required volume of the space complex by reducing the number of launch vehicles.

To assess the optimality of MTGO, we use the following indicators as an indicator of efficiency:

- the volume of MTGO at launch to the launch vehicle,

- the volume of the MTGO in orbital flight,

- the commercial potential of the created free volumes of MTGO in orbit,

- the commercial potential for the sale of electricity by SB located on the free outer surface of the MTGO.

The limits of applicability of transformable structures.

The prospects of transformable modules depend on the rational ways of using them in practical astronautics. Above, descriptions of options for orbital vehicles and on-planet structures using MTGO were presented, outlining the preliminary boundaries of applicability of transformable structures.

Large overall dimensions of deployable structures provide great opportunities in terms of providing free volumes, support surfaces in outer space, which expands the commercial use of orbital vehicles with such modules.

From table. 4 shows the limit of applicability of the MTGO, associated with the capabilities of the launch vehicle in terms of carrying capacity and available volumes under the fairings (versions of the launch vehicle of the "Angara", "Soyuz", "Proton" and "Korona" types).

The limits of applicability of the MTGO are shown in Fig. 9 along the "X" axis, and the assessment of the volumetric and economic efficiency of the MTGO is shown in the diagrams in Fig. 10 and 11.

The analysis performed allows us to note the main advantages of transformable structures:

1) Small dimensions when withdrawing,

2) Large dimensions after deployment at the site of use.

So, if we build standard modules, for example, an inflatable multipurpose laboratory module (MLM), then, based on the required level of radiation protection inside the module shell, it is practically the same in terms of launch mass and we are forced to use the same launch vehicle. That is, we do not win on delivery to orbit, but on deployment we lose on the high cost of shell materials and complex deployment technology. However, to ensure the orbital volume achieved in the MTGO, it is necessary to launch four standard modules, which is more expensive by the total cost of launching three LVs.

If we create non-standard rigid modules of a large volume, then in order to launch them, we will need to create a new rocket, and we can pack the folding module into a standard CHS. Then the savings consist in the absence of costs for creating a new launch vehicle, amounting to tens of billions of rubles and obtaining additional volumes on orbital vehicles with a commercial unit rental cost of about $ 1 million per cubic meter per year.

As for the efficiency criteria, we are improving the criterion of the relative cost of removing a cubic meter of the OS volume, since if the volume increases by four times during the deployment of the MTGO, then, accordingly, the unit cost of removing the volume decreases four times.

Large overall dimensions of deployable structures provide great opportunities in terms of providing free volumes, support surfaces in outer space, which expands the commercial use of orbital vehicles with such modules.

So, for example, on the "Angara A5" LV with the same launch cost, it can be displayed as a standard module of the "Almaz", "Salyut", FGB, MLM, NEM type with a diameter of 4 meters and a volume of about 120 cubic meters. inflatable module with a diameter of 8 meters and a volume of 420 cubic meters. meters. The lease cost of the difference in volumes can be $ 300 million per year, which ensures the payback of MTGO in one year. Income from the lease of such a MTGO for 10 years of operation can amount to $ 3 billion in volume and $ 1,400 million due to free energy resources provided by the placement of film SB on the surface of the transformer.

When creating space DOKs, for example, according to the concept of the Reaction Engine Ltd campaign [15], for the assembly of large-size expeditionary space complexes, transformers, which must also include inflatable space structures, cannot be dispensed with.

The calculation of the feasibility of the operations of launching the MTGO integrated with the MORN of the "Korona" type into the reference orbit around the Earth and the possibility of takeoff and landing of the takeoff and landing MTGO integrated with the MTEM or MORN on the Moon are given in the author's calculation tables 5, 6 and 7.

Since the required characteristic speed of the MORN entering the reference orbit is about 9270 m / s, it can be seen from Table 5 that even without using an engine with a central body, the proposed simplified MORN enters the Earth's orbit in a single-stage design on three-component liquid-propellant engines using three-component fuel (kerosene + oxygen + hydrogen). At the same time, the required dry mass of the MORN structure (tanks, KMDU, BO) can be 53.7 tons, and the mass available for the target on-board systems MTEM, MTGO or delivered components - 10.3 tons, that is, better than on a one-time multi-stage LV "Soyuz-5".

Table 6 shows that even without the use of new physical principles, the takeoff and landing MORN of the "Corona" type, refueled in a circumlunar orbit or on the Moon with ordinary water, implements launching into a circumlunar orbit (Characteristic takeoff speed from the Moon = 1800 m / s) and landing from a circumlunar orbit to the Moon (Required characteristic speed of landing on the Moon = 1900 m / s).

Table 7 shows that the available mass reserve of the MTEM-transformer to accommodate the MTGO and experimental equipment of the MTGO considered in the description can be about 15 tons.

Depending on the achieved weight perfection and technological level at the time of construction of the MTGO, it can have various configurations, in accordance with the claims of the patent formula, including the possibility of using the engine on new physical principles.

In other words, the multipurpose transformable pressurized compartment includes a hull, tanks for water and fuel, interconnected propulsion system and a pneumohydraulic fuel supply system, solar panels, a pressurized compartment containing a life support system, a multipurpose payload compartment and a service compartment, while the multilayer outer housing of the MTGO is made with the possibility of transformation, from the petals of radiation protection, meteoroid protection.

In addition, to ensure deployment inside planetary caves and increase radiation protection, the radiation protection petals of the hull are made of multilayer from elastic chambers for filling with water, and to increase protection from space debris, meteoroid protection is made in the form of a layered package of metal and polymer meshes.

The technical result of the claimed invention is to increase the efficiency of space exploration and expand the arsenal of tools for use in astronautics.

Conclusions:

The offer is more efficient than analogues, in particular: it provides a reusable solution to several tasks, is cheaper, provides the ability to fold and return.
