Description
Technical field
The present invention relates to plasma space environmental-test facility technical field more particularly to Anti-splash molsink and
Band cylinder bilayer Anti-splash molsink and above-mentioned bilayer equipped with the ground electric propulsion experiment for having above-mentioned Anti-splash molsink are anti-
Sputter the cooling means of molsink.
Background technology
Compared with traditional chemical thruster, electric thruster has the characteristics that than leaping high, thrust is small, the long-life, therefore electricity pushes away
Into the service life that can be improved the payload of spacecraft, improve rail control precision, spacecraft is substantially improved, worldwide by
To being widely applied.It is gradually ripe that the electric thruster of China also passes through the research of decades, but electric thruster is in China's satellite
The precedent of upper application not yet, and electric thruster plume splash effect influences whether the service life of spacecraft and spacecraft temperature
The normal use of the components such as control, optics can not be ignored the splash effect of spacecraft.Since plume experiment in space is very difficult
And expensive, researchers have then carried out ion sputtering corrosion effect long-term ground vacuum cabin experiment.But carry out ground
In vacuum chamber experiment, the background sputtering effect of vacuum bulkhead has seriously affected experimental result, and therefore, it is necessary to carry out Anti-splash molecule
Heavy rational design.
One important prerequisite of electric propulsion plume ground experiment is to ensure that background sputtering effect is small as possible so that experimental situation
It can reach the set quota.The design structure master to shoot at the target more in the world suitable for the splashproof of the large-scale vacuum chamber of electric propulsion
There is flat, special-shaped two kinds of formula.But all sputtering targets are all single layer structures.Structure that splashproof such as LEEP2 is shot at the target and
The splashproof of the LVTF vacuum chambers of Aerospazio companies is shot at the target using flat type, the IV10vacuum of Alta companies
The cone key protection core part of the beam that the special-shaped splashproof of chamber is shot at the target using middle with hole.
The back amount of the sputtering product of sputtering target material is considered as while the Anti-splash effect that splashproof is shot at the target is fully considered
It should lack as possible, it is possible to reduce the influence to thruster and test parts, this just needs to optimize the structure that splashproof is shot at the target
It designs to achieve the effect that long-life and the cleannes for improving test space environment that splashproof shoots at the target.
