NASA reveals 70 the working principle of air service

　　Aerospace technology for both countries is highly confidential. Especially for those most advanced in this area of the United States and Russia, it is even more important. However, with the development of China and the Western Europe and other countries and regions in space, United States aerospace technology "early" some of the secret began to lose its value. Recently, NASA released the United States used in the 70 's of last century's aviation services, such as equipment design and working principles, attracted the attention of tech enthusiasts.

　　In General, due to the existence of atmospheric pressure in the ground, under normal circumstances the pressure and blood pressure in our body in a State of relative balance. While in space, due to loss of air pressure, not to mention the hypoxia problem, if the person is in the space in the unprepared state, due to loss of blood pressure changes in the body caused by atmospheric pressure alone, it can cause people to die because of broken blood vessels.

　　Therefore, every country wants to do space walks, air service is critical to the design. Now completed this great country in the world with only Russia, United States and China. It is learned that the Chinese Shenzhou seventh spacewalk is completed when the initiative. Warehouse for the operation of two astronauts Zhai Zhigang and Liu boming was prepared by wearing two different types of air service. One is Russia design has completed the spacewalk's aviation service; the other is a self-designed field tests have not been carried out in China's aviation service. This is done to ensure that at least one person (that is, wearing a Russia human design that sets aviation suit) lives. Just proves a breakthrough in this field in China. But it can be seen that the importance of aviation service and its design development complexity.

　　The manual of the 1976 Edition of the United States air service and design principles are described in detail, as well as to the United States in the era of the space shuttle makes a simple introduction. This book is for aviation enthusiasts and technology enthusiasts have a special commemoration. If you are interested, you can buy a home study. Of course, if your English level, first to cross the border.
