In the guide vanes it's the same, best to mentinon on the first turbine vane: relatively slow, high pressure flow from the combustion chamber gets expanded & accelerated in Vane Row 1 & sent in the desired direction (strongly circumferential), for maximum momentum on Blade Row 1. That centerfire spacecraft nozzle in the RR engine is indeed hilarious | |
