Abstract
The cascade-type thrust reverser comprises a cowling in which there is formed an opening which, when in a direct thrust mode, is closed by a sliding cowl and which, in a thrust-reversal mode, is uncovered by the translation of the said sliding cowl, a fan duct being defined between an interior skin and an exterior skin, said exterior skin having a radius Re in the plane transversal to the longitudinal axis of the reverser and passing through the upstream end of the sliding cowl in the direct thrust mode, and said interior skin having, downstream of this upstream plane, a maximum radius Ri in a plane parallel to the upstream plane, the upstream end of the said sliding cowl substantially blocking the fan duct upstream of the said downstream plane in a thrust-reversal mode, the said radius Re being less than the radius Ri.
