so if they have a 600kW one they can't call it a microturbine? omg they'd have to call it something else . they could use multiple stage, and a recuperator is just a heat exchanger, how much would it weigh? as for boundary layer, that's a bit of a red flag on a forum tbh, with no numbers or sources, and 'tip losses' is a bit in the same bracketTommy Cookers wrote: ↑Mon Jul 08, 2019 3:37 pm
my Wiki says microturbines are 25 - 500 kW and 15% efficient without a (bulky, heavy) recuperator
the 'principles' of disadvantage seem to be rather strongly proclaimed ...
tip losses and the boundary layer losses are disproportionately large with small size - and short length is a hindrance
ie these don't downsize
and remember the F1 turbine has the 'free power' of exhaust pulse blowdown
and obviously it all does downsize as we're not even talking about small ones, but ones that are actually too big!!
anyway i just think they'd be extremely cool to have on an F1 car, and whatever efficiency they have now would rocket with F1 getting involved, as long as FIA didn't strangle it with limits
