Shots and military utility assessment are scheduled for Spring This is discussed in more detail below in reference to FIG. As shown in FIG. 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: The invention includes a thin, flexible sheet which can be attached by an adhesive layer to a surface of the fuselage of a rocket or missile so as to cover a wing slot Various embodiments further include a burst initiating region which is contiguous with the burst seam and formed at a location of initial contact between the deploying guidance wing and the barrier sheet, the inner layer being absent from the burst initiating region, the burst initiating region including at least one burst assisting feature attached to the outer layer in the burst initiating region, the burst assisting feature, upon contact with the deploying guidance wing, tending to press against and perforate the outer layer of the barrier sheet. The wing slot seal of claim 9 , wherein the edge of the burst assisting feature is at least one of sharp and pointed.
This application claims the benefit of U. W31P4QC awarded by the Navy. The United States Government has certain rights in this invention. The invention relates to ballistic weaponry, and more particularly to folding fin aerial rockets and missiles. The guidance wings for these weapons are typically folded within the main fuselage in a stowed configuration until the weapon is launched, at which point the wings are extended through slots in the fuselage and deployed in a flight configuration.
While foldable wing designs provide the advantages of compact storage and reduced launcher size, the slots in the fuselage required for deployment of the wings tend to create a hazard that internal components of the weapon will be exposed to contaminants. These can include natural contaminants, such as salt, moisture from fog, moisture from humidity, blowing sand, blowing dust, and such like.
The internal components can also be exposed to induced contaminants, such as debris from an adjacent rocket launch, and contaminants resulting from handling of the missile.
One approach is to provide retractable or openable covers over the wing slots. However, such mechanisms add weight and cost to the missile, take up space which may be needed for other components, and tend to be complex and prone to failure.

Country of ref document: Kind code of ref document: 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.
