▎ 摘  要

NOVELTY - The structure has a leading edge skin (1), a leading edge web (3) and a leading edge end rib (5) combined to form a closed space as a filling cavity of a graphene honeycomb (2). The graphene honeycomb is integrally formed with a hidden front edge with wave-absorbing-wave-transmitting function through an adhesive film (4). The hidden front edge is assembled together with a wing front beam (7) with wave reflection function through a detachable connecting piece, where the detachable connecting piece is arranged with a connecting corner box (6). An inner cavity of the connecting corner box is filled with wave absorbing foam. The front edge web and the front edge end rib are made of glass steel wave transparent material. The wing front beam is made of carbon fiber material. USE - Honeycomb sandwich graphene invisible front edge structure for a wing or wing front edge of a stealth aircraft. ADVANTAGE - The structure has strong universality, better wave absorbing performance of graphene material, smart structure design, convenient assembly and better and use and maintenance, and controls leading edge structure manufacturing risk. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a honeycomb sandwich graphene invisible front edge structure processing method. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a honeycomb sandwich graphene invisible front edge structure.
