Description
The on-ground casualty risk of any re-entry (controlled or uncontrolled) shall be below 1 in 10,000. One way of reducing the risk for the system is to focus on the equipment on-board.
For equipment which does not demise, the casualty risk can be reduced by design-for-demise (D4D), this is achieved by reducing the number, size, and kinetic energy of the surviving fragments associated with the equipment. To assess improvement in demisability one can use spacecraft-oriented re-entry tools (e.g. SCARAB). By studying the equipment in detail with numerical re-entry simulations and experiments using high-enthalpy wind tunnels one can ensure that the equipment will demise upon re-entry.
The current status and evolution of the equipment-level based analysis within HTG will be presented.
