Printed circuits for aircraft jet engines
This fantastic news item from AFP published in a daily a few days ago is awesome news for the future safety feature of aircraft jet engines. Essentially, conventional electric cables will be replaced by printed wiring circuits. This has already been demonstrated in two prototype jet engines. One is on display at the Australian Air Show, while another is with the French aircraft jet engine maker 'Microturbin' in Toulouse in France.
In my opinion, it is possibly the most revolutionary and a very significant safety development in the modern aeronautic jet engine technology. Among others, apart from weight saving compared to heavily insulation protected aircraft engine cables, it is most advantageous compared to conventional insulation copper wire cables now used in the aircraft engines that can logically eliminate all potential threat of sparking and igniting hazard for aircraft.
