<p> technical precision and control unprecedented high. Beijing flight control center deputy general room Ray: just a few minutes,tn pas cher, Chang E III changed the thrust under the command of the navigation guidance and control systems,tn requin, complete the main deceleration and quick adjustment. Speed down to about 50 meters per second from 1.7 kilometers per second,nike tn 2014, the height from 15 km to less than 3 kilometers. Guidance: smart "brain" Q: The power within 15 kilometers of decline, Chang E III or under autonomous navigation ground command action? Chang E III detector system deputy commander Tan Mei: power down the entire segment on ten minutes,escarpins louboutin, time is very short. Foreign counterparts to such a similar ground detectors can not directly control short period of time known as the "black moment." The program can only be set up in advance deposit into,hogan outlet, let Chang E III are "smart enough brains" - navigation guidance control system. Chang E III lander subsystems deputy chief Zhang : navigation guidance and control system is one of the major difficulties in the entire detector. We equip the new distance and speed sensor terrain recognition device as Chang E III, at the same time developed a complete set of control algorithms. Navigation guidance control system will speed ranging data and terrain data binding judgment, and ultimately the formation of a comprehensive strategy to control the propulsion system to ensure a smooth landing. China Aerospace Science and Technology Corporation Xi'an Branch of the five branches of the party secretary Li Jun: power down segments ranging speed sensors play an important role. Mounted on the lander ranging speed antenna,nike store, like sensitive "antennae", send and receive RF signals in real time,christian louboutin pas cher, and promptly transmitted to the detector control system.</p>

Park speecXinhua Beijing December 14 (Reporter Yu Xiaojie,nike pas cher, Rocha, Li Zhihui) 14 evening,barbour femme, Chang E "three girls" embrace "rabbit" 380,tn pas cher,000 kilometers from Earth, your visit to the moon,jordan pas cher, to achieve a number of Millennium's Chinese dream of flying to the moon,hogan sito ufficiale, too let China become the world after the United States, the former Soviet Union to achieve the third lunar landing. Chang-e III probe this fall, in the Sky draw a beautiful arc. It sounds relaxing and romantic.</p>
<p> real-time control Chang E III landing with respect to the speed and position of the lunar surface. Wu Feng Lei: rapid adjustment after the completion of Chang-e III into the segment and hover near the segment,louboutin homme, the height from the lunar surface gradually declined to about 100 meters, then hover. Avoidance: "We are your eyes" Q: The lunar surface bumpy,tn requin, Chang E III how to avoid the rock pit? Zhang Xiao: Chang E III near the segment has once optical imaging, the first large-scale look for a relatively flat place moved to the neighborhood.</p>
<p> it is not. Just think, the detector itself plus total 3780 kg of propellant "monster" in 11 minutes in speed to zero from about 1.7 kilometers per second, 15 kilometers from a height into a strange and bumpy landing place,tn pas cher, which is what thrilling! "Chang E" and "dodge" How to Make? Experts told reporters, researchers in the "Chang E" and "mind" in the input main gear, quick adjustment, proximity, hover,nike tn pas cher, obstacle avoidance and retarder drop six "Password." Power: push refined, become quasi Q: over the moon has no atmosphere,tn, Chang E III deceleration is how to achieve? Rocket scientist, China Aerospace Science and Technology Corporation sixth Vice President Liu Handicap: We developed a variable thrust engine tailored for the Chang-e III. It is moving in the opposite direction of the role of Chang E III sangrakwol movement, in order to achieve deceleration. Only engine "push fine,barbour paris," Chang-e III speed in order to "become quasi." Chang E III propulsion subsystem by 1 7500 cattle variable thrust engine and the number of units attitude control engine components. 7500 cattle this variable thrust engine is currently China's largest engine thrust range. This is a variable thrust engine in our lunar exploration project in China's aerospace industry and the first show. Development of difficulty.</p>
