The paddle includes an air outlet (23) in fluid communication with the cavity, where the volume of the cavity is greater than 10 percent of the total volume of the blade. The air outlet is placed in a depression area so as to maintain a naturally constant air flow through the cavity, where the cavity is partially filled with foam. Independent claims are also included for the following: (1) a turboshaft engine (2) a method for manufacturing the blade.</p> |
