N2 - A previous study by the authors has proposed a foldable heat shield that deploys by harnessing the re-entry kinetic energy, namely DEployable, Self-regulating, CENTrifugally-stiffened decelerator (DESCENT). The design benefits from being self-regulating and lightweight, having low requirement on thermal protection, and allowing downrange manoeuvre based on conventional attitude control devices. The present study demonstrates that the system mass can be scaled across 6 orders of magnitude using a set of relatively simple design rules, showing the potential to realise miniaturised entry probes that are simple and robust, with a possible mass-reduction of > 25% to an 8 m diameter inflatable heat shield.
