The space shuttle on the lubricating oil quality is more and more strict requirements. Because of the Shenzhou VI flight time is 115 hours, the lubricating oil must be in outer space, strong radiation, multi medium, weight loss and other complex flight environment to maintain stability, meet more than five consecutive days of uninterrupted flight requirements, and must be a filling. In fact, to have been long standby missiles, jet of lubricating oil. For rocket engine grease in rocket engine, can be in 10 years as the engine starting at any time to provide lubrication support. Space precision bearing lubricating oil can meet the operation for Shenzhou VI provides 17000 hours continuously, meet -60 to 250 DEG C. under the condition of speed for every 7000 minutes to turn the 11000 micro motor lubrication.

Insiders said the aerospace special oil a poor environment to adapt to high temperature technology Application to the car oil technology development, the car with the lubricating oil in the low temperature of -40 C, 50 C high temperature environment can ensure the normal start of the machine.

Seal - Shenzhou VI orbit is a cylinder, a total length of 2.8 meters, a maximum diameter of 2.25 meters, and the end of the capsule is communicated, the other end is connected with the space docking mechanism. From the capsule into orbit cabin must pass a diameter of 0.6 meters. The first flight of the Shenzhou five doors, the door is closed state, the Shenzhou six flight, the astronauts will open the door to the cabin door two Unicom. If the technology does not pass, or the seal is not good, will not open the door, the door does not close the door or leak danger. Especially when astronauts return to the ground, the two class to implement separation, in case of occurrence of the door problem of air leak. This door is the consequences be unbearable to contemplate the astronauts of the "gate of life", so the sealing requirement between the door and the bulkhead of the Shenzhou six is very high, even the hair can not have small gaps, and switch to the door Freely, but also to unlock the device, to prevent the door opening by mistake. When astronauts to return to the ground, into the return tank shut the door, they only 10 minutes of time can instruments detection door drain does not leak. The spacecraft flight in absolutely closed state. There is no air exchange and therefore require the use of lubricating oil has good biological inert, non-toxic, non volatile, ensure the spacecraft cabin safety.

Precision, scattered in the space of more than 4000 million pieces have become space transportation big security risk, these fragments although small in size, but fast running speed, is several times larger than the speed of sound. In advance do not know if the whereabouts of the garbage, once was the Shenzhou VI met May will result in difficult to expected loss. So the Shenzhou VI must be measured in advance a good track, in strict accordance with the orbit.

Experts said that although the Shenzhou VI orbit estimates reasonably accurate, but after the spacecraft, trajectory will never step by step, change complex, need not stop according to the actual position of the spacecraft observations to fine tune. Space precision bearing lubrication oil to adjust the spacecraft attitude to ensure the running direction of the spacecraft gyroscope, performance is never allowed to make mistakes. As for the gyro motor instrument oil problems, will cause problems with the spacecraft navigation.

The Shenzhou VI during takeoff, multistage rocket after launch, operation to the specified time, all levels of rocket detachment, this time the need for timely and accurate separation Rockets; return orbit cabin and the returns cabin also need to separate, spacecraft separation mechanism of the lubricating grease for problems, lead to fall off time deviation.

Temperature difference of Shenzhou VI spacecraft operation temperature difference between the two sides at least 180 DEG C, and sometimes to 350 DEG C. Spacecraft launch and operation of the huge difference in temperature requirements of lubricating oil has excellent viscosity temperature, high temperature stability, low-temperature fluidity. Ships of the lubricating oil temperature meet 80 DEG C to 260 DEG C requirements. While the vehicle launch oil ambient temperature is only 40 DEG to 50 DEG C, the oil temperature is 150 DEG C.

Quality -- because of the Shenzhou spacecraft has more than 70000 components, which any part of the small error may lead to unpredictable disaster. Therefore, space launch requirements on a per link must have strict quality guarantee, such as the US space shuttle Challenger is due to a booster rocket sealing ring for low temperature failure and lead to a disaster. For the long march rocket and the Shenzhou spacecraft, if one component of the unreliability of only 0.1%, the overall reliability of the ship also only 37%, so space launch of strict requirements the lubricating oil can not be any quality, quality defects, failure probability can not be more than one hundred thousandth.
