  • Patent number: 6964169
    Abstract: The invention proposes a long life nozzle flap for aircraft turbojets. This flap is remarkable in that it is composed of a hollow tapered body (10) flattened in the transverse direction along straight geometric generating lines (11), the body (10) forming a thin wall (12) with an approximately constant thickness E, this wall (12) comprising a continuous inner surface with a radius of curvature equal to at least 2×E, the wall (12) being made of a refractory composite material composed of reinforcing fibers (18) embedded in a matrix also made from a refractory material, the reinforcing fibers (18) being arranged in a plurality of continuous layers of fibers (18) stacked on each other, the fibers (18a) of a layer crossing the fibers (18b) of any adjacent layer.
