The invention discloses a novel muffling wing which comprises a main spar (1), wherein wing ribs (2) are arranged outside the main spar (1); a rear spar (3) is arranged in the wing ribs (2); a wing chord line (4) is arranged on the outer side of the rear spar (3) and the main spar (1); reinforcing ribs (5) are arranged between the wing chord line (4) and the wing ribs (2); the rear spar (3) is provided with shock-absorbing holes (6); and the main spar (1) is provided with muffling triangle zones (7). The novel muffling wing has the advantages of reasonable design and simple structure. The novel muffling wing can achieve the desired results when working and does not generate much resistance when flying in high space, thereby facilitating the prolonging of the service life of the novel muffling wing and better protecting the entire wing by virtue of materials.
