Mobile thrust reverser cowl and thrust reverser provided with such a cowl

摘要

A mobile cowl for a cascade-type thrust reverser includes an interior wall having an anterior zone, a movably mounted shutter and a link rod of which one end is connected to the shutter to actuate the shutter from one position to other. One of the positions may be a direct-jet position in which the shutter is situated facing the anterior zone, and other position may be a reverse-jet position in which the shutter is situated away from the anterior zone. The interior wall has, in the anterior zone, a part able to allow the link rod end to move beyond a normal position in the event of abnormal movements of the link rod end, without wrecking the interior wall.

主权项

1. A mobile cowl for a cascade type thrust reverser, the mobile cowl comprising:
an interior wall having an anterior zone and defining a cold air flow path with a fixed interior wall; at least one shutter mounted such that the shutter is articulated between a direct-jet position in which the shutter is situated facing said anterior zone and a reverse-jet position in which the shutter is situated away from said anterior zone; and at least one link rod of which one end is connected to said shutter in order to actuate the shutter from one of said positions to the other, wherein said interior wall has, in said anterior zone, a part having an exterior surface connected to an inner surface of the interior wall and forms a radial clearance with the link rod able to allow said link rod end to radially move toward an outside of the thrust reverser without wrecking said interior wall in the event of abnormal movements of said link rod end which have been brought on by at least one of an explosion of an engine duct and pressure differences in the thrust reverser cold air flow path.
