Secret Temple One: Russia and beyond to
follow
September 27 -30, the Chinese Temple One will choose the target
launch vehicle, then China will launch Shenzhou 8 spacecraft
rendezvous and docking with the space to carry out tests, taken
from China in the first step in space station
construction. One of the main temple then what is the
purpose?Temple One and the use of those
technologies? What is the significance of China's space
it? NetEase will be the exclusive interpretation
of the military.
September
20, "Temple" target aircraft, two F carrier rocket Long March has
arrived in combination launchers firing choose to wait for 27-30
days.
China's manned space program has entered the
second step
Upon completion of the
Shenzhou VII manned mission, China's manned space program for
nearly three years of silence. Although
released in August 2010 to complete assembly of the temple One
news, October 27, 2010 China's manned space station project was
officially launched, but after all, from the actual launch of
manned space flight and testing is also too
far. But
to the end of June 2011 the official release, "Temple One target
aircraft arrived in Jiuquan review by the factory", a clear
reference to the third and fourth quarters, respectively, Temple
One goal of aircraft launch and unmanned spacecraft, Shenzhou
VIII. Although
since August 18, the Long March II C rocket 11 04 satellites lost
in practice, leading to Temple One delayed the launch
time.However, after a
period of re-inspection, China announced in September 27 to 30
choose the launch One Temple. Jiuquan
Satellite Launch Center in the 921-station after a long silence, it
finally hit the headlines again, China's first space rendezvous and
docking experiments are also about to pull off.
Upon
completion of a manned orbital flight, the first step to achieve
the strategic goals of manned space flight, China started in
December 2004, the second step manned space
mission. The
second step of the manned space mission focused on spacecraft
rendezvous and docking and astronauts in space activities, the
first phase of the mission objectives for the implementation of the
main spacecraft rendezvous and docking missions and extravehicular
activity, rendezvous and docking technology breakthrough and master
the extravehicular activity techniques.
Shenzhou VII mission in
2008 in advance of the extravehicular activity during the task,
breaking the extravehicular activity
techniques. Phase
of the task to the next section, decided to set up China's manned
space project space laboratory system, developed by Temple series
of spacecraft used to implement the second strategic goal of
China's manned space flight. Technical
complexity of rendezvous and docking technology, engineering
characteristics difficult to break through to master this
technology, China's manned space engineering expertise developed
Temple One target aircraft, used for validation, breakthrough and
master the rendezvous and docking technology.One temple
is manned Shenzhou series of spacecraft rendezvous and docking
target, the target vehicle the name, very precise description of
its main purposes.
Temple One of the main purpose is
to verify the space rendezvous and docking
technology. The picture shows the complete assembly
of the Temple One target aircraft.
Temple One of the basic situation
One goal of the
Temple is about to launch aircraft length 9 meters, the maximum
diameter of 3.35 meters, a launch mass of about 8.5
tons. Temple One target aircraft is
divided into two compartments, each compartment is the JEM and
resources. JEM, according to the
preceding frame with Shanghai Aerospace developed the docking
device, for the people and the Shenzhou spacecraft
docking. JEM divided
into pre-cone, cylinder segments and post-cone, of which the first
two parts sealed pressurized environment that can support three
astronauts to work and live. JEM
and resources after the cone section a non-sealed cabin
environment, though transient, after the cone section of install
regenerative life-assurance systems, resources, installation of
various equipment such as possession of power systems, solar wings
and engines, to provide in-orbit spacecraft and space flight
applicationsexperimental support.
Temple Temple II and III programs
2010 China Manned Space Engineering Office, Wang Bao told the
English media space revealed a series of spacecraft, the details of
the temple, he pointed out that Temple II and III space laboratory
and the Temple One goal of aircraft similar quality are about
8.5 diameter
of 3.35 m tons of specifications, use the Long March II-F rocket,
will be 400 kilometers in altitude, angle of 42-43 degrees
orbit. Under the plan,
China will launch the first Temple One target aircraft, then launch
Shenzhou VIII spacecraft for rendezvous and
docking. Shenzhou VIII
spacecraft and manned spacecraft in the same configuration, but in
order to reduce the risk of rendezvous and docking test personnel
will not be manned.
Within two years of working life, China will launch Shenzhou 9 and
Shenzhou 10 spacecraft continue to work with Temple One goal of
aircraft for rendezvous and docking, which will be manned Shenzhou
10 spacecraft, whether manned Shenzhou 九号
yet OK, Shenzhou VIII will
rendezvous and docking with the Temple I make a decision whether
the test successfully. But
certainly at this stage with a temple of the Shenzhou manned
spacecraft rendezvous and docking, the actual verification of
manned rendezvous and docking capability, Temple One of the JEM's
life support system and laboratory equipment, the presence of the
flight was short, as Next was the mid-space
laboratory space to carry out scientific experiments in the
presence and accumulation of experience.
Manned space docking technology is a major
difficulty
Although there are
other goals, but Temple One main purpose of the target spacecraft
rendezvous and docking technology is a breakthrough to
master.Manned
space rendezvous and docking technology is an important technical
difficulties, either the U.S. or the Soviet Union, in the reaches
of space rendezvous and docking technology, the actual space
rendezvous and docking operations have experienced multiple
failures.
Gemini 8 in the United States and A Jinna upper stage successfully
completed before the first rendezvous and docking, Gemini 6 and 7
spacecraft rendezvous and control for the first time people, most
recently from the 180 meters earlier Gemini 3,
4, 5, rendezvous and docking experiments have
failed.Despite
the success of the Soviet Union a lot of automation and human
control of rendezvous and docking experiments, but the actual use
of the space station Salyut still frequent docking failure, even to
the number of times of peace and progress cargo ship also appeared
in hit Mir docking failure incidents.
June 29, 1995, the
U.S. space shuttle Atlantis and the "Peace" space station for
docking. Rendezvous and docking
space for the two sides should continue to be speed control and
attitude control, is also very difficult.
China docking device follow the same
structure allogeneic peripheral docking system
Although China's manned space project can only be associated with
the Russian technical exchanges, but all aspects of text and video
reports, China did not use the docking device ready pin Russia -
cone system, but follow the same structure allogeneic peripheral
docking system design. Allogeneic
peripheral docking system with the structure from the Soviet Union
in the 1970s Apollo - Alliance space docking experiments show that
docking space rescue prospects. To any of the
two docking between different spacecraft, the Soviet Union
developed a variant with the structure around the docking system,
the number APAS-75. It
overcomes the needle - cone docking system's shortcomings, the use
of any variant with a docking device structure design can only do a
passive end is also active side, which is extremely important for
space rescue, reducing the complexity of the
system. As the
peripheral-type docking system is not the needle - the central cone
system type, easier docking mechanism under the same conditions as
the total diameter of the central pressure to increase the channel
diameter.
Variant isomorphism has been widely used
around the docking system
Although the Soviet Union, then manned spacecraft, space station
Salyut spacecraft and Progress cargo to use the classic needle -
cone docking device, but the structure still further improved
variants with peripheral systems, preparing the next generation of
manned space systems in use, a new generation of Soviet
Buran Use
Code APAS-89 space shuttle system, the external diameter of 2.03 m
the original design, but then decreased to 1.55 m in diameter, due
to reduced external diameter, internal channel diameter reduced to
80 cm. Mainly
refers to the Mir space station with a needle - way docking cone at
the same time, with a quantum laboratory modules on the APAS-89 is
also the interface, and the Buran space shuttle ready for
docking.Soviet Union's space program
led to a follow-up in the water, directly Buran
retired.
"Alliance"
series of spacecraft approaching the International Space Station
docking module aimed to "needle - cone" type of docking mechanism
of the "cone", pay attention to red circle.
In preparation for building the International Space Station,
equipped with the U.S. space shuttle Buran space shuttle scheduled
for allogeneic peripheral docking system with the structure, the
manufacturer of energy consortium will re-numbered as
APAS-95. U.S. space shuttle using the
APAS-95 carried out a number of the Mir
docking. International
Space Station docking device also uses the APAS-95 docking system,
the Russian-built Zarya module and service module of the U.S. Unity
connecting node number using a variant homogeneous system, in Italy
and the United States has the Harmony node module Serenity all have
the same a APAS-95 docking system for space
shuttle. However,
the variant with the International Space Station docking system
structure surrounding the space shuttle in order to prevent massive
shock too much, allogeneic peripheral isomorphism passive docking
mechanism for the permanent end to the adaptive changes, while the
space shuttle APAS- 95 still in active and passive end-side
switch between.
China rendezvous and docking device
designed to house long Bo
One
target aircraft and the Chinese Temple Shenzhou VIII spacecraft
docking system is designed to draw on Russia's main system, but the
gambling house long to design their own
needs. From
the current data, China's rendezvous and docking measurement system
using a remote microwave radar, laser radar, close the video
navigation sensor (VGS) plus a combination of the optical sight
configuration, hardware specifications and Russian docking
mechanism APAS-89 line, in theory Harmony
and the space station with the number of nodes with a quiet cabin
on the APAS-95 docking interface, the ability, of course, because
of political obstacles from the United States, and the docking
station is not possible. Although
the space station on the APAS-95 interface, only as a passive side,
but China for security reasons, Temple Shenzhou spacecraft and
aircraft docking mechanism is unlikely to blindly
follow. One
temple can be expected after the docking device was tested, it will
become the standard of China's manned space docking mechanism,
which is the temple One of the most important contributions to
China's space industry.
Two
years of near-Earth orbit far beyond the maintenance of the
Shenzhou spacecraft design life of six months of the orbital
module, which is another of China's manned space technology,
unprecedented challenges.
Two years of near-Earth orbit to maintain
technological breakthroughs
Temple
One Although primarily designed to break through the rendezvous and
docking techniques to master, but it itself as an 8.5-ton large
space platform, it will naturally be more
applications. Temple
One and Shenzhou VIII will conduct a series of scientific
experiments in space, such as China's first manned aerospace
project of international cooperation, Sino-German joint study space
microgravity life science experiments SIMBOX Shenzhou VIII will be
put on space. Temple
One goal of aircraft will be about 400 km near-Earth orbit for two
years of a long flight, Shenzhou spacecraft is much larger than the
design life of six months of the orbital module, which opened up
the Chinese long-life low-orbit spacecraft flight area,
2 year design life if the
flight can be achieved, will be close to the Soviet Salyut 4 space
station numbers.
Potential of low-orbit space
platforms
One temple will become a huge potential of low-orbit platform,
Shanghai is now planning to bring the total material of 60 cm
diameter silicon carbide used infrared cameras to detect, in
addition equipped with a hyperspectral imaging three off-axis
optical system, anti- ,
Changchun Institute of Optics on the Shenzhou VI to achieve a 400
km height 0.5 m resolution performance, the Shanghai design objects
have and give us what kind of surprise. One
temple itself has 8.5 tons of quality, according to Wang Yongzhi,
former chief designer of the manned space project mentioned in the
article information, the Temple of the target aircraft and space
research laboratory results will be a large cargo ship and the
basis for future Space Station JEM . 13 tons
of cargo ship and aircraft temple almost identical in appearance,
20-ton after the release of the JEM picture was said to be even
more magnified version of the cargo ship.Magnification
of 13 tons and 20-ton cargo ship JEM potential, suggesting Temple
One reconnaissance platform in the near-Earth orbit on the
astronomical observations and a bright future.
Compare similar
products in the United States, if we see the future of China's
keyhole and Hubble, believe and do not feel
strange. In
fact, both of these, Temple One of the development of spacecraft
and space station cargo JEM accumulated experience and the
development paved the way for its use and subsequent Temple II
Temple run Skylab III accumulated experience, which
has value for money. From
the existing data speculation, Temple One goal of the three docking
aircraft flight time probably in 20 days, due to the flight of
Shenzhou spacecraft design life of only 7 days, Temple One of the
experiments will greatly extend the time for China's manned flight,
more long long low-orbit
flight, the space environment to study the impact on human
biomedical experiments in space.
Temple One
fact is China's first experimental space station, are responsible
for the 2020 construction of large, multi-cabin space station
technology accumulation task. Although
the quality of overall performance, especially as the Soviet
Union's Salyut Volume One, not to mention the U.S. Skylab, but
Temple One part of the performance and design specifications there
own characteristics, which reflects the efforts of China's space
and technologyprogress.
Space as an important
step towards China, Temple One will become a milestone in China's
space.
