[quote] It's a law of physics. You start to give ANY MASS a rotational velocity around a point then its going to move outwards.
Sorry but even if the forces are tiny and the movement is small the effect is still there.
However i'm not in a position to state without facts or figures if there would be any difference in ash density into the non-bypass airflow. /quote]
The bigger stuff gets thrown out further,
The stuff at the fan blade roots doesn't get much acceleration, same with birds. The spinner shape is also critical to particles heavier than air.
Pretty easy to model once you've defined the particle size.
claims-counter claims are just that unless you want to take it to the technical section
