Abstract
An air intake of a turbofan engine, capable of being fixed at the front of an engine casing enclosing the fan. The air intake includes an annular inner wall, an annular outer cowl radially spaced apart from the inner wall and of the outer cowl, a front annular partition linking downstream ends of the inner wall and of the outer cowl, a rear annular flange located in an extension of the inner wall to fix the air intake in front of the engine casing, and a front annular lip that forms with the front partition an annular de-icing chamber capable of being connected to a defrosting system. The air intake is made in at least two separable parts. The separation plane of the two parts passes outside the de-icing chamber, the inner wall, and the rear flange, and cuts out a dome in the outer cowl and a crescent with rectilinear edge in the rear partition.
