Single Piece FAN (LPC) Repair
A couple of questions on new type single piece fans (LPC) Referring to something like PW800 series.as fitted to Gulfstream G500/G600
Are they lighter than convention architecture
Do they need to be more damage tolerant
How do you prevent blades vibrating given that traditional blade mounts allow each blade to find it's optimal position.
How is the stage balanced as a complete unit - must be great casting to get such fine balance out of the mold.
How are damaged blades repaired from say a bird strike.
Wouldn't having to have entire fan stage assemblies as spare parts be more expensive than a field replacement of a single blade.
What other benefits/pitfalls haven't I thought of.
