Terrafin™ Terrafin is a simplified, single-wing configuration of Pterofin's oscillating-wing platform — a lower-complexity variant of the core technology intended for smaller-scale or lower-cost deployments. Terrafin demonstrates the adaptability of the underlying Pterofin platform: the same oscillating-wing principle, scaled down to a single wing rather than the multi-wing configurations used in Skimmer and Manta. The videos below show Terrafin prototype testing. Explore the Technology
