slat slot vortex generator confusing me
keep mixing these up in practice test. as i understand it - slot is just the gap, slat is the moving panel on leading edge that opens and makes the slot, vortex generator is small separate fin that just re-energises the boundary layer, not making any slot at all. is this correct or am i missing something

why 120 degree for stainless not 118
always use 118 degree drill for normal jobs. why stainless need 120 and slow speed, not fast like i thought for harder metal. is it because it work hardens if you go too fast? anyone know the actual reason not just the answer
