De-Icing Splitter Lip for Axial Turbomachine Compressor

摘要

The present application relates to a de-icing splitter lip for a low-pressure compressor of a turbofan aircraft engine. The splitter lip surrounds the primary flow and includes an annular splitter wall with a circular leading edge, an outer shroud connected to the splitter wall, and a heating device in an electric ribbon that de-ices the splitter lip. The splitter lip further includes an elastic element made of elastomer, holding the heating device on the inside of the splitter wall. The elastic element is compressed, pre-loaded, in the splitter lip. Thus, the elastic element exerts a force F clamping the heating device against the splitter wall and the outer shroud in order to improve thermal contact. The present application also provides a method for assembling a splitter lip.

主权项

1. A splitter lip for a turbomachine, the splitter lip comprising:
an annular splitter wall with a circular leading edge; a heating device configured in order to de-ice the splitter lip; and at least one elastic element holding the heating device on the inside of the splitter wall; wherein the at least one elastic element is pre-stressed in the splitter lip so as to exert a clamping force F on the heating device towards the splitter wall.
