Abstract: A nacelle for an aircraft propulsion unit, includes at least one safety rod capable of holding a cowl open when the rod is placed in a holding position. The rod is configured so that it can be arranged, by moving at least one of its ends, in a flight position so as to fulfill a structural reinforcement function when the cowl is closed.

Abstract: A propulsion unit for an aircraft, includes a support structure, a nacelle and a turbomachine. The support structure is configured to independently support, on the one hand, the turbomachine and, on the other hand, preferably by a cradle, an air inlet and/or a rear section of the nacelle.

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.

Abstract: A propulsion unit for an aircraft includes a gas generator; an air inlet; and a sealing system inserted axially between the air inlet and the gas generator. The sealing system has at least: a compression ring with a first axial end configured for mechanical connection to one of the gas generator and the air inlet. The compression ring also has a second opposite axial end configured to be axially separated from the other of the gas generator and the air inlet by an annular space. An annular seal is mounted in the space and configured to be axially compressed by reduction of the axial dimension of said space.
