amazing machine! do you have the core engine for the back nozzles and the FAn (powered by core engine) for the front nozzles and for charging up the core engine? i would love to look inside this!
Have you ever tried to detect if it experience compressor stall? Cause i think you need to have twin fan to compress more and to stabilize the negative effect of compressor stall or compressor surge.
During the whole demonstration, I was fixated on the lack of heat effect on the background behind where the heat should be ! No Heat ? is this a cold turbine maybe ?
Educated guess: Only the rear outlets have hot exhaust, but the background is just grey low contrast asphalt so it may be that the video compression ignores the subtle effect of heat haze.
