Hello everyone,
I have some questions about Hot spot measurements for peening with blade turbine.
What did you put in your internal standard as reference? the whole "burnt" spot that appear on the steel sheet, or did you specify/determine the center of it?
How did you determine the thermal center of it? thermal imagery?
I have read some litterature where they state that the hot spot is at 2/5 of the length of the burnt spot. Is true for all straight blades turbines?
Some company (winoa for example) use thermal imagery, but how precise is it? how can you really measure the location of the spot?

have a nice day.
