Chen Yue team from 2010 to officially launch EM engine research. The team relies on the classical electromagnetic field theory analysis and calculation, carried out the thrust chamber design. Through analysis and calculation, the researchers believe that the thrust generated from the electromagnetic field in a specific design of the resonant cavity generated by the uneven distribution, so the technology does not require traditional working fluid, in fact, the use of electromagnetic force on the material, Consistent with the laws of classical mechanics.
"We have successfully developed several specifications of several prototype principle, the establishment of experimental verification platform to complete the milli-level micro thrust measurement test, through several years of repeated tests and the corresponding interference factors investigation test, confirm that the type of thruster Thrust exists. "Chen Yue introduced that they have completed the test device can be used for flight test development, is in orbit verification.
"This technology is currently in the latter stages of the proof-of-principle phase, with the goal of making the technology available in satellite engineering as quickly as possible," said Li Feng, chief architect of the China National Space Technology Institute's communications satellite division. , The principle prototype volume, thrust is small, require special engineering methods, optimize the cavity design, improve the cavity quality factor, reduce the loss, the microwave energy is more effective for generating thrust. At present, the thrust is measured to micro-cow level to millennial level, at least to improve the level of 100 cents or even cattle-level satellite can be used for attitude control, orbit and other work.
He explained in detail, from the proof of principle to the application of the project, need to solve the current prototype prototype thrust is small, push power ratio is low, the thruster is difficult to work long hours, thruster layout, application strategy and a series of engineering problems, if these engineering problems Have been resolved, EM engine engineered applications will enable space technology to promote inter-generational leap. These technical problems, although there are great difficulties, but in engineering can be resolved.
Li Feng said, Chen Yue team relies on national related project support, is carrying out engineering application of key technology research, for 5 years to achieve engineering applications, "we have mobilized microwave, structure, thermal control, power electronics, on-board electronic systems and other related professional Strength, to do this thing, although difficult, but we have the confidence to make.

Not very clear and not so sure, but interesting report.
Some other buzz reports test in Chinese space station... some just that Yang Juan, unlike previous reports of failure, continues the reserach and have achievements....
Buzz Buzz... we have to be careful but watching. Success is not to exclude.
