ABSTRACT:
A novel seal is provided for sealing the annular gap between a tube and a cylinder, such as between a missile and its launch canister, which comprises an annular base for engaging the outer surface of the missile, an annular flap formed integral with the base and extending radially outwardly and downwardly to seal the annular gap between missile and canister, the annular flap having formed thereon means to control the location of buckling around the periphery thereof upon compression of the seal within the gap. The means to control the buckling of the flap include, in one representative embodiment, a plurality of prebuckling webs or, in an alternative embodiment, a plurality of slit pairs regularly spaced around the circumference of the flap, to promote buckling of the seal at predetermined locations.
