Abstract:
A device for guiding a stream of air entering a combustion chamber of a turbomachine is disclosed. The device includes a flow straightener followed by a diffuser. One of the flow straightener shrouds is formed as one with one wall of revolution of the diffuser. The other flow straightener shroud is added and attached to the other wall of revolution of the diffuser. The vanes of the flow straightener are secured by one end to one shroud of the flow straightener and separated by a small clearance from the other shroud at their other end.
