” God eight “three questions

answers were: Shenzhou VIII spacecraft chief designer Zhang Bonan

■ Shenzhou VIII: Exalted spacecraft Why not?

Shenzhou VIII perform the first space rendezvous and docking missions, compared to the Shenzhou V, Shenzhou VI, Shenzhou VII, its the nature of the tasks has greatly changed, there are certain security risks , it is not on the astronauts.

■ Shenzhou VIII: This boat was no one like?

Shenzhou VIII although not astronauts, but all environmental conditions, are designed in accordance with one state. Mini “kitchen space”, a special “space conditioning” mini “space hospital” and so on, all kinds of equipment readily available, but no one operating it.

■ Shenzhou VIII: The Chinese spacecraft shaping the future of the standard version?

Shenzhou VIII spacecraft in history, the biggest improvement, technology, the device state changes to 51%, which is China’s future version of the Shenzhou series of spacecraft shape the future of manned spacecraft, the the Shenzhou VIII prototype, local optimization and updates.

bus performance

intelligent system upgrade

all stand-alone devices made

● new research equipment accounted for 15%, 40% improved equipment, technology equipment accounted for changes in the state 51%

● docking mechanism and increase the appearance of relay antennas, all stand-alone devices are localized

curtain opened, China’s aerospace history’s first “space bus” Shenzhou VIII to show in front of reporters –

9 meters long and weighs 8082 kg, the maximum diameter of 2.8 meters, the largest wingspan of 16.9 meters … … The superior performance of the manned spacecraft, the chief designer Zhang Bonan so excited: “This is the future of China Shenzhou series of spacecraft stereotypes version! “

” Shenzhou spacecraft has a span of this step. “Zhang Bonan said,” and the United States and Russia after the two models before entering the standard transportation systems, our development of the Shenzhou spacecraft from aimed at this goal early on to do, whether developed or developing time efficiency are greatly improved. “

” Shenzhou VIII spacecraft ever biggest improvement, more than 600 sets of equipment, new research facilities about 15%, about 40% improvement of equipment, technology equipment state changes to 51%, is a new world and from the aircraft … “Despite two days did not sleep a wink, but a talk about his” children “, Zhang Bonan still high spirits.

compared to the Shenzhou VII, Shenzhou VIII to take on what? And less of what? Answer this question, necessarily involves the Shenzhou VIII of the two missions: First space rendezvous and docking technology breakthrough, the second is to achieve a manned spacecraft stereotypes.

Shenzhou VIII spacecraft overall design engineer Yang Haifeng Speaking to reporters the changes in the spacecraft: mission to complete the rendezvous and docking, orbital configuration of the new measure new communications equipment, to achieve a greater distance relative to the whole measurement coverage, front-end installed docking mechanism, the internal channel diameter of 800 mm.

new generation of CNC computer for the Shenzhou VIII even paying attention, the ability to more, higher IQ … In Yang Haifeng seems most proud of is that “Shenzhou VIII are all stand-alone devices achieved domestically. ”

“shape after the spacecraft, the internal design of more humane.” Shenzhou VIII did a lot of man-machine ergonomics evaluation, for example, the position of the handle docking, the astronauts can adjust the length of the arm, adaptive more.

In addition, Yang Haifeng told reporters, because Temple One, Shenzhou VIII responsible for carrying goods and greatly reduced the space experiments, spacecraft, space shuttles so that “pomp.” The future, the Shenzhou spacecraft will gradually return to its standard role – full-time manned flying.

space passengers

physical signs of lifelike dummy

full and accurate record of flying experience

● The two dummy body weight 75 kg, according to the real flight cabin space suits worn

● box simulation of the physical test ECG, respiration, body temperature, blood pressure signal downstream ground

wearing a white cabin space suit, lying in a small chair pot, the body was tightly bound with a fixed … … Shenzhou VIII spacecraft launch, you will see this cabin scene.

unmanned spacecraft where’s the astronaut? Look closely, you will understand that this is the physical dummy.

Reporters learned from the Chinese astronaut center, according to a manned spacecraft Shenzhou VIII is equipped with two standard dummy body, the astronauts used to simulate flight conditions.

aerospace medical experts Xu told reporters that two of the dummy body weight 75 kg, according to the real flight cabin space suit to wear, clothing boxes installed on the physical test, to simulate the resulting ECG, respiration , body temperature, blood pressure and other physiological signals, the collection and transmission, the lower to the ground.

According to reports, real flight, this close relationship between four astronauts physiological health of flight, you need real-time monitoring, medical monitoring and medical analysis for the ground. Astronauts will test 24 hours wearing a vest of physiological signals, pass their time under the physiological indicators.

“because no astronaut Shenzhou VIII spacecraft, will not really produce ECG, respiration, body temperature, blood pressure and other physiological signals, so we use anthropomorphic host of physiological signals, analog issue these signals, the signal transmission assessment link is normal for the next manned flight validation. “Xu said.

body cabin space suit worn by the dummy, is the spacecraft launch and orbit phase of the astronauts return to the necessary “first line”, an emergency can save lives. Once the spacecraft cabin leaks, the pressure suddenly drops, the cabin space suit oxygen supply to immediately provide protection.

spacesuit expert Liu Xiangyang, told this reporter only in the spacecraft cabin in the space suit equipped with astronauts living in the Temple I do not need to wear to work. He also revealed that being female cabin space suits astronauts to study for their body feature is designed to ensure comfortable fit.

“return cabin has three seats, two of which were above the safe holiday, put another experiment supplies, there are three seat cushion, can protect the astronauts.” Shenzhou VIII spacecraft overall design engineers to make the Soviet Union, the “return to the cabin has space daily to simulate the process of landing, the astronauts use. All in all, manned spacecraft design and the status of all exactly the same.”

car equipment

protect other facilities

featured ride comfort

● cabin equipped with a mini “kitchen space”, a special “space conditioning” mini “space hospital”

● Manual control can also be automatically controlled, for future astronauts flying trip to provide reliable protection

you may see luxury car with a bar, but you never think of “God eight” this “space bus” was actually with the “kitchen.”

fish-flavored pork, kung pao chicken, boiled fish … this is the future of astronauts in space, three meals a day part of the recipe. Cooking these dishes, the food placed in the cabin just a length, width and height less than 30 cm silver containers can be done automatically.

this tailor-made for the Shenzhou spacecraft, the food heating device, weighing only 4.4 kg, has a good impact resistance, anti-vibration performance, both compact and practical, known as mini “kitchen space” , literally. Research personnel, future spacecraft can also increase fluid heating device, at any time for the astronauts on the hot glass of apple juice, orange fruit or pure water … …

Reporters learned that Shenzhou VIII is not only equipped with a “space kitchen “, also has a special” space conditioning “mini” space hospital “, manual control of these facilities can also be automatically controlled, for future astronauts flying trip to provide reliable protection.

Shenzhou VIII spacecraft, the gas flow control devices, temperature regulating devices, space suit as environmental control and life protection sub-systems products, like a “space conditioning” in the astronauts in flight test, ensure that cabin with suitable living and working environment.

space suit temperature adjustment device that regulates the temperature inside the space suit, space suit to adapt the space to ensure that the sudden cold, sudden hot environment. Because of differences in the space environment, this “air” design principle and use, and very different from everyday household air conditioning.

miniature “space hospital”, mainly through the physical test case, ECG recording devices, medical monitoring and biological and chemical detection devices, quality measurement instrument to monitor astronauts ECG, respiration, body temperature, urine and other key physiological indicators, and automated analysis of the data transmitted to ground equipment, ground personnel to the physical condition of the astronauts in real-time monitoring. In addition, there is a special fitness space – neuromuscular stimulation, muscle fatigue to help astronauts recover.

It is commendable, “the hospital space” in these devices, small cigarette size, but the largest adult palm.

frequency routes

land sea and sky together based escort

space shuttles all the way through

● two relay satellites to join, so that monitoring and control coverage from 17% to 69%

● 230 Multiple fault plan, the spacecraft reliability and security than substantial increase in the past

the saying goes, a good road car, even better.

Shenzhou VIII this “space bus”, the world go round “highway”, for many people are familiar with – the starting point is the Jiuquan Satellite Launch Center is located in the Basalt of Inner Mongolia of the end the landing site area.

in this world and from the “highway” from the “one God” to “seven gods”, the Shenzhou-7 spacecraft to create a 100% safe driving record. Road safety no doubt.

ordinary reinforced concrete highway is pouring from one meter one meter, and this world from the “highway” is the China Aerospace Science and Technology personnel with the most advanced information technology tools and inch by inch, paved percent. This road, now the China Aerospace Science and Technology who has built over 20 years.

“rendezvous and docking tasks of high-precision determination of rail, high degree of guidance control, monitoring and control management, the twin goals of a series of new requirements.” Monitoring and control communication system stability in Beijing, said Xie, deputy chief designer, scientific and technical personnel devoted to “highway” for a new round of upgrades for the Shenzhou VIII to create a more secure and smooth “road conditions.”

worth mentioning is that our own design, development and construction of land-based Trinity Marina manned control communication network, the first official work for the rendezvous and docking mission escort. Two relay satellite to join, so that monitoring and control coverage increased to 69%.

special mission made a special request. Unlike in the past is that this car “space bus” departure time is very harsh: the spacecraft must be “zero window” launch, via the site are to arrive on time!

safe and smooth return to the spacecraft, rendezvous and docking mission is an important indicator of success. To this end, Shenzhou VIII spacecraft designed 230 fault plan, a substantial increase in reliability. Return capsule and landing parachute improved buffer system, the weak link has been enhanced with advance umbrella, so that the capsule has a recycling capacity of more than 50% margin.

effective back-up measures, so that “space bus” line is more stable and reliable. A plan not to use Plan B, B with C program plan not only one purpose – to ensure smooth all the way from the spacecraft to achieve world.

” Alliance “series of spacecraft is a Soviet/Russian manned spacecraft to use the longest series, divided into the Soyuz, the Union-T, Soyuz-TM-TMA and the Alliance several stages of development. Soyuz can carry three astronauts, with orbital maneuvering, rendezvous and docking capability, shuttle astronauts for the space station, but also in the dock with space station after the flight, the world’s most reliable systems in the world of space shuttles.

“Alliance” series of spacecraft on April 23, 1967 the first launch, so far, more than 90 ships were launched. It is the largest diameter of 2.72 m, a launch weight of 6600 kg, from the capsule, the orbital module, service module components.

U.S. space shuttle family

U.S. space shuttle made a total of six. The earliest available is the “pioneer” was, but only for testing, never perform space missions. “Columbia” is the oldest member, it was April 12, 1981 the first launch, February 1, 2003 in the implementation of its 28th mission, unfortunately crashed. “Challenger” in the January 28, 1986 for its 10th explosive disintegration of the space mission.

“Discovery” space shuttle is the family’s “attendance of the King”, which in its nearly 27-year flying career, the implementation of the 39 space missions, to stay in space to create a record 365 days. “Endeavour” and “Atlantis” was a space shuttle’s two younger members of the family. July 21 this year, “Atlantis” was staged at the Kennedy Space Center, “curtain call tour”, the end of the U.S. space shuttle 30 years of age.
