Abstract
A shield assembly for protection of vehicles traveling in space consisting of at least five layers that would replace the thin metal impact shield in Whipple shields fabricated using the current art that employs only a single metal. All of the layers in the present invention are metallic. At least three different metals must be used in this invention. FIG. 1 shows the basic embodiment of the transparent blast protection assembly. The shield assembly (10) comprises a first metal layer (20), a second metal layer (30), a third metal foam layer (40), a fourth metal layer (50), and a fifth metal layer (60). At least one spacer component (70) is used to create and maintain a space between the structure requiring impact protection (80) and the shield assembly.
Claims8
a shield assembly comprising:
- (a) a first metal layer having a melting temperature less than 700 degrees Celsius at atmospheric pressure,
- (b) a second metal layer contiguous with said first metal layer, the metal comprising said second metal layer having a density greater than the first metal layer and having a melting temperature less than 700 degrees Celsius at atmospheric pressure,
- (c) a third metal foam layer, said third metal foam layer being contiguous with the second metal layer and having a pore size typically greater than 0.5 millimeter and density less than 60% of the density of the same metal without porosity,
- (d) a fourth metal layer having a density exceeding 8 grams per cubic centimeter contiguous with the third metal foam layer,
- (e) a fifth metal layer, said fifth metal layer having a melting temperature less than 700 degrees Celsius at atmospheric pressure and a density exceeding 7 grams per cubic centimeter, and
- (f) at least one spacer, said spacer causing a space to be formed between the fifth metal layer and surface of an object being protected against penetration by an object impinging on the first metal layer, said space being at least 5 centimeters prior to impingement by an object on the first layer.
