Chi­nese sci­en­tists study use of wire­less charg­ing tech­nol­ogy in rock­ets

Global Times US Edition - - TOPNEWS -

China’s space sci­en­tists are now ex­plor­ing ways of us­ing wire­less charg­ing tech­nol­ogy in rocket de­signs.

Liu Fei, the project man­ager at the China Academy of Launch Ve­hi­cle Tech­nol­ogy (CALT), said dozens of de­vices in any rocket, in­clud­ing the con­trol sys­tem and teleme­try, still need to be con­nected by ca­ble to the power sources.

“Ca­bles weigh­ing hun­dreds of kilo­grams form a huge net­work with a wide va­ri­ety of hid­den dan­gers and a mul­ti­tude of po­ten­tial prob­lems,” Liu said.

Liu noted that com­pared to small elec­tronic prod­ucts, wire­less power sup­plies and in­for­ma­tion trans­mis­sion in rock­ets are a very com­pli­cated busi­ness.

“One bat­tery needs to sup- ply power to all de­vices through elec­tro­mag­netic in­duc­tion, but each de­vice has a dif­fer­ent work­ing mode. Our task is to re­duce in­ter­fer­ence for bet­ter re­li­a­bil­ity and se­cu­rity,” Liu said.

Ac­cord­ing to CALT, once wire­less tech­nol­ogy ma­tures, the weight of a rocket will be re­duced by at least one hun­dred kilo­grams, which means an ex­tra hun­dred kilo­grams of pay­load. Xin­hua
