ABSTRACT:
A fairing 122 is provided for covering a wire strike cutter 120. The fairing 122 comprises a microwave energy absorbing core 150 covered by dielectric skin 160,161,165,166. The fairing 122 reduces the radar signature of the wire cutter and fractures in response to a wire strike so as to permit the cutter to capture and cut a wire/cable. At least one projection 135 is formed on the fairing 122 for catching a slack wire/cable as it slides up the fairing, the projection holds the wire/cable until tension develops to fracture the fairing, thereby permitting the wire/cable to pass through to the wire cutter where it is subsequently cut. The fairing 122 minimizes drag and improves the aircraft's aerodynamic characteristics by directing the airflow around the wire cutter and equipment adjacent to the wire cutter.
