Cooled turbomachine blade

The blade has pins (23) of high thermal conductivity along the trailing edge (14), alternating with blow-out apertures (22) in the trailing edge material (141). The pins project into the trailing edge cooling channel (12), conducting heat from the trailing edge material to improve the cooling of the...

More Information
Summary:The blade has pins (23) of high thermal conductivity along the trailing edge (14), alternating with blow-out apertures (22) in the trailing edge material (141). The pins project into the trailing edge cooling channel (12), conducting heat from the trailing edge material to improve the cooling of the trailing edge without increasing the number of blow-out apertures.
