Abstract
L'invention a pour objet un dispositif de refroidissement par impact des segments d'étanchéité de turbine d'un turboréacteur. Conformément à l'invention, le flux d'air de refroidissement entrant dans une enceinte 9 concentrique aux segments est divisé en deux circuits de ventilation distincts par une virole 17 de forme générale circulaire ayant des ondulations 17a d'amplitudes dégressives d'amont en aval. Application au refroidissement des turboréacteurs d'aviation.
