Abstract: A method of cutting a wafer of composite core from a bulk composite core including the steps of placing the bulk composite core in a container, the bulk composite core having a plurality of tube members; depositing a potting compound in contact with an outer surface of the bulk composite core; curing the potting compound; and after curing of the potting compound, cutting through each of the tube members. A method of cutting a wafer of composite core from a bulk composite core, the method comprising the steps of stabilizing the bulk composite core by wrapping an exterior of the bulk composite core with a composite wrap, the bulk composite core having a plurality of tube members; curing the composite wrap; and cutting through each of the tube members.

Abstract: An aircraft includes a wing positioned below a vertical rotor, the wing extending in a transverse direction to a wingtip having an outboard face, and a turbulence feature located on the wingtip and oriented to induce turbulence in the rotor downwash flowing across the outboard face in a direction from a top surface of the wing to a bottom surface of the wing.
