NASA Testing Aims at Supercooled Large Droplet Aviation Safety

US · 2026-10-05

1. Step 1 · The triggerNASA's Icing Research Tunnel tests produce calibrated supercooled large droplet (SLD) drop-sizing data across the full droplet size spectrum.
2. Step 2 · Knock-onThe calibrated SLD data feed the Subsonic Flight Demonstrator project, improving its icing-condition measurement capability.
3. Step 3 · Knock-onBetter SLD measurement tools give the aerospace industry improved engineering tools for designing aircraft ice protection systems.
4. Step 4 · Knock-onAircraft manufacturers and suppliers adopt the improved tools, leading to more efficient ice protection designs and potentially lower certification costs.
5. Step 5 · Reaches youUS SMEs in the aerospace supply chain see reduced design iterations and testing expenses for ice protection components.
