subject: Cheap Porsche Piwis [print this page] Zhongguang Wang, Beijing, June 17 (Xinhua Zhang Mian Mian) According to the Voice of China "CNR news reports, the Shenzhou No. 9 spacecraft orbiting the Earth one hour consumption how much Maybe you could not guess, only 1800 watts, equivalent to an ordinary home air conditioning or power consumption of the high point of a power microwave, but the spacecraft and home appliances, but full of a big head. Day flying down the "divine nine" power consumption of only 43 degrees. Although the "divine nine" power consumption is small, but there was a strong "heart" of the power system, always as "God nine flight to provide power protection. According to the power system development and production of eight homes of the China Aerospace Science and Technology Corporation 811 technicians, Shenzhou on the 9th power system three kinds of power, solar sailing, Ni-Cd battery, emergency battery. A few hours before the rocket launch, the power system will be fully charged from the moment the rocket began to work. After the rocket launch, people will be very concerned about whether the spacecraft solar panels can proceed smoothly because the power system is actually a PV system, like a small "farm", the source of energy is solar energy, solar cells windsurfing launched power system to work properly. Rely on solar electricity, part of the supply spacecraft, part of the battery storage. "Shenzhou on the 9th orbiting the Earth circle about 90 minutes, during which more than 50 minutes of light in the sunlight, the solar panels can work properly and charge storage batteries. But there are more than 30 minutes in the shadow of sunlight, solar windsurfing will stop working, this time to maintain the spacecraft to the normal operation of the electricity from the nickel-cadmium batteries prior to storage of good electricity. Itlike we usually use the phone, only the battery is charged to work properly, so in the light of the battery is charged, the spacecraft in order to maintain normal operation. Rendezvous and docking implementation, the "One Temple ()" and "Shenzhou No. 9" will work together to fly, due to the location of the "One Temple" obscured the spacecraft part of the solar windsurfing, occluded part is not the normal charge . In order to solve the problem of maxiscan ms509 energy balance, after a successful rendezvous and docking, "Temple One" will "Shenzhou on the 9th part of the electricity," Shenzhou on the 9th only need ten minutes of electric charge in more than 50 minutes can a. In addition, the power system also has an important role of "help". In case the spacecraft mishap, emergency battery will be hired. The emergency battery is a high-performance than the new silver-zinc battery, acts like a UPS. The event of an emergency, the spacecraft back to the ground requires four hours, emergency battery can ensure that the spacecraft power supply, and fall to the ground search and rescue system to provide 24 hours of electricity. Astronauts in the sky flying ten days, the power consumption must rely on the power system. One of the manned space project, due to the limited power supply capacity, the astronauts fear the costs of electricity, could not bear to heat meals, are left-eat. Second phase of the manned space power systems, solar panels of the material using a three-junction GaAs, compared with a use of polysilicon, the power generation autoboss v30 capacity has doubled. It also makes the more the robustness of the power system. Meanwhile, the power system using high-pressure system, and reduced loss. An adequate supply of electricity, the "Shenzhou No. 9 to ensure that the astronauts to attend a lecture to eat hot meals.
