I know only 2 ways for start an tuboreator,because it doesn t start himself like piston engines: start with electric motor or with little piston engine(gazoline or pressured air)!!
i had the chance to see one original jumo in british museum, who was cutted for check inside: it s little piston engine starting!!(see the red arrow!!)
General electric start with electric motor :wink:



so i think we should heard the little air pressure piston engine first, and in same time the turbine getting speed, at the end the turboreator start with loud sound and get more speed again...

but anyway this video look great, i m waiting for the new U.I. and others

cheers
