- Rotor inspection: non-destructive, dimensional and geometric checks, balancing.
Implementation / working method :
Interactive, one-day, face-to-face course. Powerpoint support will be shared at the start of the course in paper and digital formats.
A questionnaire will be sent to trainees before the course in order to adapt the course content to participants' expectations as far as possible.
A course evaluation questionnaire will be distributed to participants at the end of the course.
