RQ-2-4
Thermal warping effects on large thin-film membranes in the solar environment
Simulation Methodology
This Monte Carlo simulation models thermoelastic warping of large thin-film membranes under solar illumination, a key engineering challenge for Dyson swarm collector satellites.
- Equilibrium temperature from radiative energy balance with PV conversion
- Front-to-back thermal gradient from emissivity asymmetry (~8%)
- Thermoelastic curvature: kappa = CTE x dT / thickness
- Flat membrane deflection: w = kappa x L² / 8
- Tension counteraction reduces effective deflection toward zero
- Stochastic variation: CTE +/-10%, emissivity +/-5%, tension +/-15%
Key trade-off: Larger membranes capture more energy but require higher tension to maintain flatness within phased array tolerances (5 mm) or structural limits (10 cm).
