Abstract
A notched blade seal for covering a gap between a wing and a wing flap of a high performance aircraft includes a bottom seal strip of a flexible, resilient material having a plurality of spaced-apart notches defining a plurality of finger portions, and a top seal strip, also of a flexible, resilient material having a plurality of spaced-apart notches defining a plurality of finger portions. The top seal strip overlies and engages the bottom seal strip and is positioned relative to the bottom seal strip such that the finger portions of the top seal strip overlie and cover the notches in the bottom seal strip.

A notched blade seal for covering a gap between a wing and a wing flap of a high performance aircraft, comprising:
- a bottom seal strip of a flexible, resilient material having a generally right triangle cross-section configuration and a plurality of spaced-apart notches defining a plurality of finger portions, and
- a top seal strip of a flexible, resilient material having a generally right triangle cross-section configuration similar to the bottom seal strip and also having a plurality of spaced-apart notches defining a plurality of finger portions,
- the top seal strip overlying and engaging the bottom seal strip along one leg of the generally right triangle cross-section configuration and being positioned relative to the bottom seal strip such that the fingers of the top seal strip overlie and cover the notches in the bottom seal strip.
A notched blade seal for covering a gap between a wing and a wing flap of a high performance aircraft, comprising:
- an elongated bottom seal strip having a generally right triangle cross-section configuration and a plurality of spaced-apart notches defining a plurality of spaced-apart finger portions, and
- an elongated top seal strip having a generally right triangle cross-section configuration similar to the bottom seal strip and also having a plurality of spaced-apart notches defining a plurality of finger portions,
- the top seal strip overlying and engaging the bottom seal strip along one leg of the generally right triangle cross-section configuration and being positioned relative to the bottom seal strip such that the fingers of the top seal strip overlie and cover the notches in the bottom seal strip,
- each seal strip having a substantially uniform width along a longitudinal extent and being tapered widthwise from a thicker edge to a thinner edge, and
- the notches and fingers being along the thinner edge.
