Manned cabin
Manned spacecraft
The main structural feature of manned spacecraft is that it has manned module.Its main structure can be divided into several compartments, for example, two compartment structure and three compartment structure can be used.If there is a docking mission, there is a docking mechanism, which is placed at the front of the spacecraft.The first generation of Soviet spacecraftVostok Its structure is very simple. It is a two compartment type. The spaceship only carries one person.When the second generation spacecraft flew, the SovietAscending signThere is an extra one for getting out of the cabinAirlock, and can carry 2-3 people;The United StatesGemini spacecraftIt is still a two compartment plus docking mechanism.The third generation spacecraft is a three compartment structure, such as the SovietSoyuz spacecraft。The front end of this kind of spacecraft is the docking mechanism, then the orbital module, and then theReturn capsuleAnd service cabin, and finallyCarrier rocketto be connected.Some cabins are connected by transition cabins.Having the mission of leaving the cabinManned spacecraftAir locks for exit are added.U.S.AApolloIn addition to the two compartment structure, the NoLunar module。
Orbital module
Manned airshipOrbital moduleIt is the key segment of the spacecraft.The docking mechanism at its front end is used for spacecraft to connect with other spacecraft orspace stationFor butt joint, its lower end is connected withReturn capsuleto be connected.It is a space for astronauts to carry out scientific experiments, eat, exercise, sleep and rest in space flight, which is equipped with food, water andSleeping bag, waste collection device, observation instrument and communication equipment, etc.The orbital module can also be used for astronaut extravehicular activitiesAirlock。
Return capsule
It's also a closed cabinOrbital flightHour andOrbital moduleTogether, they are called astronaut quarters.In the take-off phase and re-entry phase, astronauts are half lying on the seats in the cabin, and have a certain angle to overcome the pressure of overweight.In front of the seat is the dashboard to monitor the flight situation;The attitude control handle is installed on the seat to adjust manually in case of automatic control failure.U.S.AMercury spacecraft When returning to the ground, the automatic control fails, and the astronauts manually control the spacecraft to return to the ground.Before the spacecraft returns to the ground, the orbital module and service module are respectivelyReturn capsuleThey were separated and burned during re-entry, and only the return capsule carried the astronauts back to the ground.
Service cabin
The service cabin of manned spacecraft can also be called "instrument equipment cabin".Its front end is connected with theReturn capsuleConnected with the rear endCarrier rocketConnect.Soyuz spacecraftThe cabin is divided into front and rear parts. The front section is sealed and pressurized. It is equipped with electronic equipment, environmental control, propulsion system and communication equipment;The rear section is non sealed, mainly for the installation of derailment engines, storage tanks and other objects.Installed outside the service cabinEnvironmental control systemRadiator andSolar panel。[2]
Manned spaceships fly around the earth and return safely, which can study people's reaction ability in the process of space flight, and how people can withstand spaceship takeoff, orbital flight andRe-entry into the atmosphereThe study of the conditions and equipment necessary for long-term survival in the space environment will help us understandSpace environmentImpact on human body, development and utilization for human beingsSpace resourcesTo achieve long-term space navigation, so as to achieve alien immigration and accumulate experience.
Manned spaceflightIt is the further deepening of human understanding of space, the use of space microgravityhigh vacuumandStrong cosmic particleRadiation and other space resources, conducting scientific experiments under microgravity conditions, and producing materials that cannot be produced on the ground, have always been the dream of mankind since the realization of manned spaceflight.For decades, astronauts have“Space factory”Achievements made in, for human development and utilizationSpace resourcesBringing dawn.
Over the years, astronauts have carried out a large number of space material science experiments in space, the purpose of which is to use the unique spacemicrogravity Under the condition of no gravity interference, study the characteristics of materials and produce various materials that cannot be produced on the ground.Space material processing and technology development areManned spaceflightThe inevitable product of development.Since the realization of manned spaceflight, astronauts have studied the physical laws of material processing under microgravity conditions in space and produced many new materials. At the same time, the research on space material processing technology has also been developed rapidly.
A series of biotechnology and life science experiments carried out by mankind since the realization of manned spaceflight have made important achievements in deepening the research of human life itself, synthesizing new drugs, resisting the impact of various diseases, extending life and improving the quality of life. At the same time, they have also established long-term living bases on space stations or extraterrestrials for the future,It provides a controlled ecological environment and life support system, and makes theoretical and technical preparations.
For decades, astronauts have carried out a series of biological experiments in space, mainly focusing on the study of biological material, energy cycle and regulationbiosphereResearch;utilizemicrogravity Promote the research of life process and gravity biology research on how the microgravity environment affects the formation, function and behavior of biological organisms on the earth;Radiation biology research on damage and protection of organisms exposed to space high-energy environment;In addition, there are organismstissue cultureExperiments are used for in vitro cell and tissue culture of organisms for various physiological studies when the whole organism cannot be used for experiments.
Conduct engineering and technical tests
Not implementedManned spaceflightPreviously, tests on new technologies and materials needed by human beings to conquer space could only be carried out on the ground. After manned spaceflight was realized, various tests could be carried out in space.The use of manned spaceflight for engineering and technical experiments is convenient and accurate. Therefore, whether the space shuttle of the United States or the former Soviet Unionspace station, both take engineering technology experiment as an important task.Over the years, in order to prepare for large-scale space activities, space maintenance and space operations, a large number of simulation tests and hardware operation experiments have been carried out to verify the feasibility of its methods and technologies.At the same time, new technologies, new materials and new processes in the development of new spacecraft were tested.Thus,Manned spaceflightServed as a pioneer for the further development of space industry.
Observing Earth and Cosmic Celestial Bodies
Observing the Earth in space is not only“A view of mountains”In addition, when humans enter space, they find that under space conditions, due to overcoming the interference of the atmosphere, the observation effect of ground and celestial bodies is far better than that of ground conditions, especially those that cannot be carried out on the groundX-rayDetection and ultraviolet detection can be carried out conveniently in space.More importantly, manned space flight can give full play to humanSubjective initiativeTherefore, compared with satellite observation, it can change passive observation into active observation, so it can achieve better results than satellite observation.
Important use
The important purpose of the manned spacecraft is to serve as a space shuttle to pick up astronauts for the space station.Former Soviet Union/Russia“Gun salute”The astronauts on the space station No. and the space station No. Mir are transported by the manned spacecraft No. Soyuz.“The International Space Station”The main means of delivery is also a spaceship.
Manned spaceships are also lifeboats. Astronauts work in the space station for a long time, and there may be dangers at any time, such as outer space micro meteors orArtificial celestial bodyDebris breaks through the bulkhead of the pressure chamber, the control system of the space station is unstable, or the astronaut suddenly gets sick. In case of the above emergencies, the astronaut needs to leave the space station immediately and return to the ground.For this reason, when astronauts work in the space station, at least one manned spacecraft docks with the space station as an orbital lifeboat, ready to pick up astronauts at any time to leavespace station, return to the ground.[3]

Apollo spacecraft detected fire
On January 27, 1967,Kennedy Space CenterThe ground joint simulation flight test of manned spacecraft was conducted on the No. 34 launch site.
Riding with three astronautsApolloThe 4A spacecraft docked atSaturn 1B carrier rocketOn.The three astronauts are: once participated inMercuryNo. 4Suborbital flight、Gemini 3Colonel Fergil Bugrisom, who is very experienced in flying, once participated in the Gemini 4 flight and was the first US Lieutenant Colonel Edward H. White to walk in space, and another is Major Roger B. Chafei, who is preparing for the first flight in space.If the ground simulation test is successful, the three astronauts will take this spaceship to enter the ringOrbital flightTo test the degree of moon landing flight.
Later, it was found that the reason for the fire was that the spacecraft wire was short circuited, and the electric spark ignited the plastic products in the cabin.Apollo spacecraft1/3atmospheric pressureSome plastic products that were originally fire-resistant in normal air became flammable in pure oxygen.In addition, the opening time of the cabin door is designed to be 90 seconds. Negative pressure is formed inside the ship when the fire occurs. The cabin door cannot be opened in a very short time, whether outside or inside.
Soyuz 1 returns and crashes
In April 1967,Former Soviet UnionNewly developedSoyuz spacecraftThe planned lunar landing flight rendezvous and docking simulation test was carried out, and the Soyuz 1 and Soyuz 2 were scheduled to be launched on April 23 and 24, respectively, and then on April 25-26Earth orbitRendezvous and docking, and space transfer.
At 3:35 a.m. on April 23, Colonel Vladimir M. Komarov took the Soyuz 1 spaceship and, amid cheersBaikonur Launching Site Launch on time.
At lap 2,KomarovThe report said: "The left side of the spaceshipSolar cellThe sail is not turned on, and the power supply is insufficient,Radio shortwavetransmitterjobless.Attitude stabilization systemAlso affected, the spacecraft is in irregular operation. "By the fifth lap, the spacecraft fault was further aggravated.Komarov tried to eliminate the fault and tried to start the engine of the spacecraft to stabilize the flight, but failed.Exhausted, Komarov requested a sleep on lap 10.With permission, the communication with the ground was interrupted.At lap 13, communication with the ground flight control center was restored.However, the fault of the spacecraft has not disappeared and the attitude is still unstable.The flight control center decided to suspend the launch of Soyuz 2, and Soyuz 1 returned immediately.
On lap 17, the spacecraft failed to adjust its attitude and failed to return.At the 19th lap, Komarov manually controlled the return, making the spacecraft enterReturn to orbit。When the spacecraft descends to an altitude of 10km from the ground according to the return orbit, the mainparachuteThe ground commander heardKomarovSaid, "The parachute did not open!" At 6:24 on April 24, the spaceship rushed to the ground with a flash of fire at a speed of more than 100 meters per second and landed atUralSome violent explosions were heard 65 kilometers east of Orsk.Komarov died on the spot.
Air leakage when Alliance 11 returns
On June 6, 1971,Alliance 11The spaceship came fromBaikonur Launching Site Launch and launch, carrying the first batch of shouldersSalute 1 space stationThe three astronauts with heavy responsibilities flew towards the space station.These three astronauts are George DobroWolski, Vladislav Volkov, Victor Pachayev.After the orbit change flight, the spacecraft began rendezvous and docking 100 meters away from the space station, and succeeded. Three astronauts opened the cabin door and entered the space station.
They stayed at the space station for 23 days, 18 hours and 22 minutes, and carried out a series of astronomical observationsweightlessnessThe experiment of growing under the conditions and some medical experiments have obtained a lot of valuable information and done quite well.During docking, the orbit of the space station was raised twice.
At 9:00 p.m. on June 29, 1971, three astronauts leftSalyut 1 return.But none of the three wore themSpace suit。After leaving the space station, the spacecraft flew for more than 4 hours and kept in touch with the ground.At 1:35 on June 30, 1971, the spacecraft started according to the procedureBrake rocket。On reentryatmospherefront,Return capsuleandOrbital moduleSeparation.However, after the separation plug connecting the two cabins was separated, the pressure valve of the return cabin was opened, the sealing performance was damaged, the air in the return cabin leaked from there, and the cabin was rapidly decompressed, which caused the astronauts to suffer from acute hypoxiaBody fluid boilingAnd death.
The reason for this accident is that the design of the spaceship is unreasonable and the cockpit is crowded. Only by taking off the bloated spacesuit can we sit down.At that time, the Soyuz return procedure was clearly stipulated,astronautThe spacesuit must be taken off before returning.Many scientists objected to this design and procedure at that time, but the leaders of the space sector did not accept the correct opinions.To this end, the Soviet Space Director CardMa NingThe general was dismissed from his post.[9]
