# What is the speed the fan blade would go if it would separate from the shaft with the engine at full throttle?

I'm making a simulation of a blade separating from the shaft to test the case of the engine, but i don't know what speed should i put on the blade to go outwards the case, anyone has any idea how to measure this? thank you

You can compute the actual velocity at any point of the blade, it's the product of the perimeter of the point path and the rpm: $$v = \pi d * rpm / 60$$, in m/s if the distance d is in m.
