Submission of a report.
Experimental investigation in ENSAM wind tunnel.
Tests of a wind turbine and determination of its characteristic curves: thrust, torque
and power. Analysis of results and submission of a testing report.
Initiation to scientific communication.
The student is asked to do a personal work within a small group about a research subject in the field of wind enegy. A specific bibliographic revue must be prepared. This work must be finalized as a written paper respecting a given template and also as an oral presentation.
