A simple approach for the design and optimization of stand-off hypervelocity particle shields
We describe a simple engineering model applicable to stand-off ``Whipple bumper`` shields, which are used to protect space-based assets from impacts by orbital debris particles. The model provides a framework for analyzing: (1) the parameter limits governing the penetration and breakup or decomposition of the hypervelocity debris particle; (2) the behavior of the induced debris cloud, including its velocity and divergence; and (3) the design and optimization of the stand-off shield for a specific threat and level of protection required. The model is normalized to actual stand-off debris shield experiments and multi-dimensional numerical simulations at impact velocities of {approximately} km/s. The subsequent analysis of a current space station shield design suggests that: (1) for acceptable levels of protection, stand-off shields can be significantly thinner than previously thought; and (2) with the proper balance between shield thickness and stand-off distance, the total shield mass can be reduced substantially. 16 refs.
