A Bounce-Regime Impact Cushion: Crush Stroke and Peak Load for a Landing Pad Using Torsion Pressure Near the Bounce
Year: 2026
Type: article
Abstract: This paper presents a complete design study of the device is a landing cushion pad, sized here for a two-tonne descending vehicle, built around a crush core of spin-polarised material whose resistance rises steeply as it is compressed, in the manner that torsion pressure rises as matter approaches a bounce rather than a singularity, derived from stated assumptions and computed throughout by the accompanying script. A 2000 kg vehicle arriving at 8 m/s carries 64.0 kJ, and a half-metre stroke holds the mean deceleration within the crewed limit only up to about 5 m/s in the plain absorber case; the stated torsion enhancement shortens the required stroke by up to the percentages tabulated for polarised fractions to 0.30. Every figure in the study is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
