Estimating the term…
A low cost, lightweight frangible wing slot seal can be applied to a guidance wing slot of a folding fin aerial rocket or missile, providing a barrier against exposure of internal missile components to external contaminants, while allowing unhindered deployment of missile guidance wings simply by bursting through the seals. The simple design is nearly foolproof, and has no impact the likelihood of weapon failure. The seal is a flexible sheet which is sufficiently thin so as not to exceed the required volume envelope of the missile. The sheet includes a burst seam, which is breached when impacted by the leading edge of a deploying wing. No additional wing deployment force is required, and after deployment the seal has minimal impact on the aerodynamic performance of the wing.
A frangible wing slot seal suitable for preventing penetration of contaminants through a wing slot provided in the fuselage of a folding fin aerial rocket or missile, the wing slot seal being frangible so as to permit deployment of a guidance wing through the wing slot by breaking of the guidance wing through the wing slot seal, the wing slot seal comprising:
