,christian louboutin pas cher as well as the impact of jet engine landing will raised dust, these boosting not only affect the success of lunar dust, but the lander will cause some harm. " In addition,doudoune moncler homme, Chang E III detector with many new technologies, products sub-sample, low product maturity; and flight procedures and very complex, especially in recent months, brake,chaussures giuseppe zanotti pas cher, power down process, high flight timing requirements, the need flight control detector strict chronological execution, otherwise it will affect the completion of the main tasks. Faced with a number of risks, Chang E III research team in the early sample stage, fully validated to risk identification, adequate identification,giuseppe zanotti sneakers, test verification fully focus on ensuring technical bottom; turn to the sample after he offered to "grasp the key link comprehensive quantization control, fine operation to implement "as the focus, to ensure product reliability, risk control. To ensure that the process of in-orbit flight timely and accurately locate the fault, and the fault handling process is completed in the shortest possible time, to develop a team from two key flight events and public service system to sort out failure mode,air jordan italia, the lander plans to develop more than 140 items , Patroller plans to develop more than 70, specifically in rail failure criterion and disposal measures for the detector to provide a strong guarantee the implementation of the flight control. Six innovation to meet the challenges Faced with new technology, difficult, and complex systems risk the enormous challenge and a difficult period, Chang E III research team has tackled the landing deceleration, autonomous navigation control landing stage, cushion the impact of the landing, the lunar surface thermal control guarantee .

Arduous process of research, make a lot of participation in the task of designers unforgettable. Chang E III detector system Ting new commander,woolrich parka, said Chang E III detector has "four new dilemmas over two-tight" distinct characteristics. Among them, the "four new" refers to the new environment facing the lunar surface temperature,peuterey prezzi, lunar dust, regolith, the lunar surface topography, etc; identification equipment accounted for more than 80 percent of new development platform; for the new loading device is equipped with new scientific exploration and working relationships Coupling high,tute nike, high degree of product integration of the new model. "Two more" mainly landing navigation sensors, thermal control two-phase fluid loop Patroller lunar surface moves Patroller remote operation for the new technology represents a more and technologies span; involved in the development, design and experimental verification more collaboration supporting units. "Dilemma" is reflected in the ground verification is difficult, especially in a soft landing characteristics of the decision by the whole weight loss is difficult. "A tight" is reflected in the tight schedule,nike air max italia, from the project to launch just five years and 9 months, complete from the beginning of the sample program demonstration, being kind, launch various stages of development work,zanotti pas cher, etc., as well as dozens of related products research, hundreds of sets / kits single.

lunar surface movement,scarpe firmate nike uomo, lunar process of autonomous navigation and remote operational control of six major aspects of key technologies. Variable thrust engine landing deceleration crack problem. After the launch,abercrombie fitch, Chang E III flew toward the moon, until designers carefully selected power drop points. In this case, if it continues to rapidly advance, Chang E III on landing on the moon could a hit, resulting in unimaginable consequences. Therefore, we must allow her to slow down. As we all know,zanotti femme, the lunar surface without atmosphere. Therefore,scarpe hogan, Chang E III was unable to take advantage of aerodynamic deceleration approach landing, can only rely on its own propulsion system to reduce the speed detector in this process but also for precise adjustment of attitude, and gradually slow down to a safe landing in a predetermined area. To ensure the landing process control,abercrombie soldes, research team after repeated demonstration, that "variable thrust propulsion system" design scheme,chaussure homme louboutin, developed adjustable thrust 7500N variable thrust engine, after several ignition test and associated test verification, cracked landing deceleration problems. The new technology help landing segment GNC system of autonomous navigation control. According to the lander GNC (Guidance Navigation and Control) System Director Designer.

probe power down process is a relatively short time, varies greatly speed the process, we can not rely on the ground in real-time control. In this regard, GNC system design a special sensor,air jordan italia, conducted on May speed,hogan scarpe, distance and terrain recognition.

identification and other pieces of development and production, several large-scale special experimental verification, development schedule is very tight. Where is the greatest risk points as the country's first celestial body other than Earth spacecraft implementation of a soft landing, as compared with any previous satellite missions, Chang E III detector affect the success or failure of the mission? "There is no doubt, is the uncertainty it brings the moon and the lunar environment," Chang-e III lander division vice president, said Zhang, "From the available information, the lunar surface is covered with a layer of the lunar surface rock chips, powder, breccia composed of lunar soil, and this layer of soil and very soft and bumpy; the same time, when sangrakwol specific lunar surface topography can not be completely sure that these bring to a safe landing unavoidable risk. And when the lander impinge on the lunar surface.
