chinese astronauts walk in space for the first time in the weight loss, dark and cold of space, the astronauts how to accurately calculate the “space walk” time? The astronauts will wear shenzhen Fiyta developed “God 7 Space Form,” into space. Fiyta official said, a few space watches are developed in a simulated space environment out, they can pressure, shock, anti-magnetic and can be -80 ℃ to 80 ℃ environment, work properly. Meanwhile, in the dark space where astronauts can distinguish between day and night so that the precise time of the Earth.

Watch weight than ordinary double

Watch this space, its size larger than the average watch, take up heavier. According to reports, extravehicular spacesuit watch because of its unique performance requirements than regular watches to be significant at about 1-fold. In order to minimize the weight of extravehicular spacesuit watches, Fiyta technicians watch the selection of materials and structures made a lot of improvements, especially in case of space materials using titanium.

    As early as October 2003, china’s space hero Yang Liwei, the wear Fiyta table provides a dedicated space to achieve “the Millennium Flying Dreams.” In October 2005, the “Shenzhou VI” astronauts Fei Junlong and Nie Haisheng They were wearing two Fiyta space form, the successful completion of space missions.

Facing the harsh environment in space complexity

With the two previous space trip is different is that the “Shenzhou VII” flight will be completed the first Chinese astronaut to walk in space missions, watch extravehicular spacesuit worn during extravehicular spacesuit, the direct face of complex and harsh working space the environment, including: the launch and landing phase of the vibration acceleration of the environment, a vacuum environment, space temperature of the environment, radiation environment, magnetic environment, atomic oxygen environment, micro-gravity. The wearing of the extravehicular spacesuit, the extravehicular spacesuit watches the need for direct face of the space environment, such as the space temperature environment, magnetic environment and the vacuum environment. After Fiyta technical personnel more than three years of scientific research and technological research, to capture a lot of research and technological difficulties, completed the development of extravehicular spacesuit watch.

    Be able to distinguish day and night inside the dark space,

“In the EVA, the only way to see the light of the technical equipment is a table of space. This space for all the details of the table are based on the needs of astronauts in space operations designed to: specially designed for astronauts” space walk “design a special time-dial for the astronauts to complete the task within the allotted time to provide technical support; the calendar shows a change in the way to a special window displays, so that the dark space, the astronauts can know that the earth be divided into day and night to protect the space Members of patterns of life can be time synchronization with the Earth.

In space, space the table to face the sun this powerful radiation source, γ-rays, X-rays, ultraviolet, visible, infrared, microwaves and radio waves and other wavelengths of the electromagnetic radiation and magnetic environment in space has a great influence on the watch, the main affect the accuracy of watches, when walking and may cause stop watches to go, so watch the space to bear Fiyta 10 times higher than the national standard of the magnetic field strength of the technical indicators, through a thorough magnetic shielding and magnetic shielding radiation environment and the impact of environment on the watch, the indicator has reached the international advanced level.

Ordinary Table into space will stop and go

Space into the space, the technical requirements of the table is very high, if an ordinary watch into the space, what would happen?

According to reports, as an ordinary watch, national standard operating temperature of -5 ℃ to 50 ℃, if an ordinary watch exposed to specific temperature in the space environment, first of all stop taking the phenomenon occurs, a number of organic materials will also aging and becoming brittle. Also in a vacuum environment, the ordinary watch the pressure due to internal than external large, the table may be off the glass.
