Abstract
A propulsion unit for an aircraft includes a gas generator and an air intake with an upstream annular lip that is axially translatable. The propulsion unit further includes a sealing system of an annular shape that is borne by the lip at its downstream edge. The sealing system has an annular envelope with a downstream annular surface configured to bear on an upstream edge of the rest of the air intake. The sealing system also includes at least one elastically deformable member situated at the downstream edge of the lip and configured to be elastically deformed by compression and to exert an elastic return force on the envelope.
