Fractal fragmentation analysis model for aerospace vehicle breakup presented at 9th Australia Space Science Conference
Ian Bryce, our space engineering adviser, presented his novel fractal fragmentation analysis model for aerospace vehicle breakup to the 9th Australia Space Science Conference in Sydney. This conference was sponsored by the National Space Society of Australia and the Australian Academy of Sciences.
Our conference paper describes how, using fractal fragmentation modelling, a vehicle breaks up into a small number of fragments with certain ratios, and then each fragments breaks again into the same ratio, and so on. This process continues to a number of degrees between 1 and 6, depending on the ratio of the forces applied to the structural strength of the vehicle, tank etc. The one model transitions seamlessly from low to high intensity events and between aerodynamic break and internal explosions. It has been extensively verified against known cases where fragments were recovered.
The fractal fragmentation model is currently being used as part of the Range Safety Template Toolkit (RSTT) to analyse air-launched guided weapons and to support the HIFiRE joint US / Australia collaborative hypersonic flight research program involving a series of suborbital space launches and hypersonic controlled flight from Woomera, South Australia.
