Abstract

See full text

The present application relates to a splitter nose of an axial turbomachine designed to separate an annular flow into the turbomachine into a primary flow and a secondary flow for undergoing a thermodynamic cycle. The nose includes a de-icing device with a wall defining, at least partially, an annular channel. A hot oil stream created by the turbomachine circulates in this latter. The oil runs through the circular nose and de-ices it while itself getting cooled. The wall is located so as to form the leading edge of the said splitter nose. The wall is an open or closed strip such as a tube which can be fixed by bonding, welding or recessing. The present application also relates to a multi-flow turbomachine with splitter noses fitted with de-icing devices.
