Scientific paper

An analysis is described for defining the limits of perforation protection against cometary meteoroids achievable by shielding systems. One and two element shield concepts of four materials are treated with worst case models which define meteoroid masses above which no perforation will occur. Dual element shields are shown to provide two to three orders of magnitude greater protection than single element shields. In the context of the ESA Comet Halley probe mass and area constraints, protection against meteoroid masses in excess of one gram, striking at 57 km/s, is demonstrated.
